In Filecoin, users pay to store their files on storage providers. Storage providers are computers responsible for storing files and proving they have stored them correctly over time. Anyone who wants to store their files or get paid for storing other users’ files can join Filecoin. Available storage, and the price of that storage, are not controlled by any single company. Instead, Filecoin facilitates open markets for storing and retrieving files that anyone can participate in. + +Filecoin is built on top of the same software powering [IPFS protocol](https://docs.ipfs.tech/), which is a peer-to-peer distributed storage network that leverages [content addressing](https://docs.ipfs.tech/concepts/content-addressing/) to allow permanent references to the data, and avoids relying on specific devices or cloud servers for addressing the content. Filecoin is different from IPFS because it has an incentive layer on top to incentivize contents to be reliably stored and accessed. + +Filecoin enables several use cases, from Web3 native NFT and metaverse/game assets storage, incentivized permanent storage, to archiving Web2 datasets as a cheaper alternative to cloud storage. For example, [NFT.Storage](https://nft.storage/) utilizes Filecoin to provide a simple decentralized storage solution for NFT contents and metadata, while [Shoah Foundation](https://sfi.usc.edu/) and [Internet Archive](https://archive.org/) leverages Filecoin to backup their contents. Filecoin also supports a wide range of formats of data, including audio and video files, allowing Web3 platforms such as [Audius](https://audius.co/) and [Huddle01](https://huddle01.com/) to leverage Filecoin as the decentralized storage backend for music streaming and video conferencing. diff --git a/SUMMARY.md b/SUMMARY.md new file mode 100644 index 000000000..1480b4ae7 --- /dev/null +++

Due to the diversity of data transport protocols in the IPFS ecosystem, Lassie is able to use the Graphsync or Bitswap protocols, depending on how the requested data is available to be fetched. One prominent use case of Lassie as a library is the **Saturn Network**.

Anybody can join the Filecoin network without needing permission. Running a storage provider only requires an internet connection and spare disk space. By lowering the barriers to entry, Filecoin enables a thriving ecosystem of many independent storage providers. + +#### Competitive prices + +Prices for storage and retrieval are determined by supply and demand, not corporate pricing departments. Filecoin makes reliable storage available at hyper-competitive prices. Miners compete based on their storage, reliability, and speed rather than through marketing or locking users in. + +#### Reliable storage + +Because storage is paid for, Filecoin provides a viable economic reason for files to stay available over time. Files are stored on computers that are reliable and well-connected to the internet. + +#### Reputation, not marketing + +In Filecoin, storage providers prove their reliability through their track record published on the blockchain, not through marketing claims published by the providers themselves. Users don’t need to rely on status pages or self-reported statistics from storage providers. + +#### Choice of tradeoffs + +Users get to choose their own tradeoffs between cost, redundancy, and speed. Users are not limited to a set group of data centers offered by their provider but can choose to store their files on any storage provider participating in Filecoin. + +#### Censorship resistance + +Filecoin resists censorship because no central provider can be coerced into deleting files or withholding service. The network is made up of many different computers run by many different people and organizations. Faulty or malicious actors are noticed by the network and removed automatically. + +#### Useful blockchain + +In Filecoin, storage providers are rewarded for providing storage, not for performing wasteful computations. Filecoin secures its blockchain using proof of file replication and proof of storage over time. It doesn’t rely on energy-intensive proof-of-work schemes like other blockchains. Miners are incentivized to amass hard drives and put them to use by storing files. Filecoin doesn’t incentivize hoarding of graphics cards or application-specific integrated circuits for the sole purpose of mining. + +#### Provides storage to other blockchains + +Filecoin’s blockchain is designed to store large files, whereas other blockchains can typically only store tiny amounts of data, very expensively. Filecoin can provide storage to other blockchains, allowing them to store large files. In the future, mechanisms will be added to Filecoin, enabling Filecoin’s blockchain to interoperate with transactions on other blockchains. + +#### Content addressing + +Files are referred to by the data they contain, not by fragile identifiers such as URLs.

When a file becomes popular, it can be quickly distributed by swarms of computers instead of relying on a central computer, which can become overloaded by network traffic. + +When multiple users store the same file (and choose to make the file public by not encrypting it), everyone who wants to download the file benefits from Filecoin keeping it available. No matter where a file is downloaded from, users can verify that they have received the correct file and that it is intact. + +#### Content distribution network + +Retrieval providers are computers that have good network connections to lots of users who want to download files. By prefetching popular files and distributing them to nearby users, retrieval providers are rewarded for making network traffic flow smoothly, and files download quickly. + +#### Single protocol + +Applications implementing Filecoin can store their data on any storage provider using the same protocol. There isn’t a different API to implement for each provider. Applications wishing to support several different providers aren’t limited to the lowest-common-denominator set of features supported by all their providers. + +#### No lock-in + +Migrating to a different storage provider is made easier because they all offer the same services and APIs. Users aren’t locked into providers because they rely on a particular feature of the provider. Also, files are content-addressed, enabling them to be transferred directly between providers without the user having to download and re-upload the files. + +Traditional cloud storage providers lock users by making it cheap to store files but expensive to retrieve them again. Filecoin avoids this by facilitating a retrieval market where providers compete to give users their files back as fast as possible, at the lowest possible price. + +#### Open source code + +The code that runs both clients and storage providers is open-source. Storage providers don’t have to develop their own software for managing their infrastructure. Everyone benefits from improvements made to Filecoin’s code. + +#### Active community + +Filecoin has an active community of contributors to answer questions and help newcomers get started. There is an open dialog between users, developers, and storage providers. If you need help, you can reach the person who designed or built the system in question.

See the [GitHub docs](https://github.com/consensus-shipyard/ipc-agent/tree/main/docs) for a conceptual overview. + +### Installation + +#### Prerequisites + +To build the IPC Agent you need to have Rust installed in your environment. The current MSRV (Minimum Supported Rust Version) is nightly-2022-10-03 due to some test build dependencies. A working version is tracked in rust-toolchain (this is picked up by rustup automatically). You can look for instructions on [how to run Rust and rustup following this link](https://www.rust-lang.org/tools/install). + +{% hint style="info" %} +️According to the operating system you are running, you may have to install additional dependencies not installed in your system to follow these instructions like `build-essentials`, `libssl-dev`, `git`, `curl`. If something fails while building the binaries double-check these dependencies. +{% endhint %} + +#### Build instructions + +To build the binary for the IPC agent you need to build the requirements in your environment, clone this repository, and build the binary following these steps: + +```shell +git clone https://github.com/consensus-shipyard/ipc-agent.git +cd ipc-agent +rustup target add wasm32-unknown-unknown +make build +``` + +This builds the binary of the IPC agent in the `./bin` folder of your repository. If you want to make the command available everywhere, add this folder to the binary `PATH` of your system. To see if the installation was successfully you can run the following command: + +```shell +./bin/ipc-agent --help +``` + +### Infrastructure + +IPC currently uses [a fork of Lotus](https://github.com/consensus-shipyard/lotus), that we like to call _Eudico_, to run its subnets. The IPC agent does nothing by itself, and is just an orchestrator over existing subnet deployments. To ease the deployment of new subnets and nodes, we provide a set of convenient scripts to deploy all the infrastructure required to run IPC. + +#### Install infrastructure scripts + +[Eudico](https://github.com/consensus-shipyard/lotus/tree/spacenet/scripts/ipc) provides a set of infrastructure scripts, which assume a working installation of Docker. To install Docker [follow this link](https://docs.docker.com/get-docker/) and choose your working environment. + +{% hint style="info" %} +Some users have reported issues trying to build the required images using Docker Desktop, if this is the case, try installing a version of [Docker engine](https://docs.docker.com/engine/install/#server) supported by your system. +{% endhint %} + +With Docker installed, you can then `make install-infra` in the root of the `ipc-agent`. This make rule will clone the Eudico repository, build the docker image that you need to run subnets, and install the infrastructure scripts in the `./bin` folder. In Unix-based systems, it is highly recommended to include your user inside the `docker` group to avoid having to run many of the commands from this tutorial using `sudo`. You can achieve this running the following commands: + +```shell +sudo usermod -aG docker $USER newgrp docker +newgrp docker +``` + +To check if the installation of the image and all infra-related scripts was successful you can run the following command, and it should return a similar output: + +```shell +docker images | grep eudico +# eudico latest 8fb6db609712 2 minutes ago 341MB +``` + +### Usage + +#### Configuration + +If you are running the agent for the first time, the first thing you need to do is to create a new config. The default config path for the agent is `~/.ipc-agent/config.toml`. The agent will always try to pick up the config from this path unless told otherwise. To populate a sample config file in the default path, you can run the following command: + +```shell +./bin/ipc-agent config init +``` + +If you `cat ~/.ipc-agent/config.toml` you should see a new config populated with a sample root and subnet configurations. + +#### Running the daemon + +The IPC agent runs as a foreground daemon process that spawns a new JSON RPC server to interact with it, and all the processes to automatically handle checkpoints and the execution of cross-net messages for the subnets our agent is participating in. The agent determines the list of subnets it should interact with from its config file. + +Alternatively, the agent can also be used as a CLI to interact with IPC. Under the hood, this CLI sends new commands to the RPC server of the daemon. To run the IPC agent daemon you can run: + +```shell +./bin/ipc-agent daemon +``` + +Running the agent at this point will throw an error, because we haven´t configured it to interact with any IPC network. In the next few sections we will walk you through different alternatives to spawn and connect your agent to a running IPC instance. + +The RPC server of the daemon will be listening to the endpoint determined in the `json_rpc_address` field of the config. If you are looking for your agent to be accessible from Docker or externally, remember to listen from `0.0.0.0` instead of `127.0.0.1` as specified in the empty configuration. + +### Interacting with a rootnet + +#### Spacenet + +For more information about the Spacenet testnet have a look at the [Spacenet repository](https://github.com/consensus-shipyard/spacenet). In this section we will guide you through how to connect your IPC agent to a running instance of Spacenet. Spacenet hosts all the IPC actors and can be used as a rootnet to deploy new subnets from. + +In order to use the IPC agent with Spacenet we need to have access to a full-node syncing with the network. The easiest way to achieve this is to run your own Spacenet node. Running you own Spacenet node is as simple as [installing the dependencies](https://github.com/consensus-shipyard/lotus#basic-build-instructions), cloning the Eudico repository, and compiling and running it: + +```shell +git clone https://github.com/consensus-shipyard/lotus +cd lotus +``` + +The `spacenet` branch is the main branch in the repository. To find the latest release deployed over Spacenet, you can check the [last release](https://github.com/consensus-shipyard/lotus/releases) published in the repository and use checkout that tag: + +```shell +git checkout +``` + +Compile Eudico for Spacenet: + +```shell +make spacenet +``` + +Run your node: + +```shell +./eudico mir daemon --bootstrap=true +``` + +With this, your node should automatically connect to the bootstraps of the network and start syncing the latest state of the chain. + +{% hint style="info" %} +More information and further details about the operation of Spacenet can be found in the [Spacenet repository](https://github.com/consensus-shipyard/spacenet). +{% endhint %} + +With the node running, you are ready to connect the IPC agent to Spacenet. For this, you’ll need to get an authentication token for your node, and point to the RPC API of the node (by default running on port `1234`). + +```shell +# Generate auth token to node +./eudico auth create-token --perm admin + +eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJBbGxvdyI6WyJyZWFkIiwid3JpdGUiLCJzaWduIiwiYWRtaW4iXX0.8vIV7pCrWx-nxOBAAw_IayDzrGf22kMjagRYmj_8Qqw +``` + +Additionally, you should create a new wallet address (if you don’t have one already) to use for your IPC interactions. You can create a new wallet by running the following command in your Eudico node: + +```shell +# Create new wallet +./eudico wallet new + +t1cp4q4lqsdhob23ysywffg2tvbmar5cshia4rweq +``` + +With all this information, the config of the agent should be updated to connect to the peer and start interacting with Spacenet’s IPC by editing the following section for the `/root`: + +```toml +[[subnets]] +id = "/root" +gateway_addr = "t064" +network_name = "root" +jsonrpc_api_http = "http://127.0.0.1:1234/rpc/v1" +auth_token = "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJBbGxvdyI6WyJyZWFkIiwid3JpdGUiLCJzaWduIiwiYWRtaW4iXX0.8vIV7pCrWx-nxOBAAw_IayDzrGf22kMjagRYmj_8Qqw" +accounts = ["t1xbevqterae2tanmh2kaqksnoacflrv6w2dflq4i"] +``` + +You can now start your IPC agent daemon with `./bin/ipc-agent daemon`. + +{% hint style="warning" %} +In the current implementation of Spacenet, the gateway is always deployed in the `t064` address. This should be the address always reflected on your config for the gateway. In the future, this will change, and the gateway may be deployed in different addresses. +{% endhint %} + +To check if the agent has been connected to Spacenet successfully you can try creating a new wallet in the network, but this type through the agent by running: + +```shell +./bin/ipc-agent wallet new --key-type=bls + +2023-03-30T12:01:11Z INFO ipc_agent::cli::commands::manager::wallet] created new wallet with address WalletNewResponse { address: "t1om5pijjq5dqic4ccnqqrvv6zgzwrlxf6bh2apvi" } in subnet "/root" +``` + +Finally, to be able to interact with Spacenet and run new subnets, some FIL should be provided to, at least, the wallet that will be used by the agent to interact with IPC. You can request some Spacenet FIL for your address through the [Spacenet Faucet](https://spacenet.consensus.ninja/). + +#### Local deployment + +To deploy sample rootnet locally for testing you can use the IPC scripts installed in `./bin/ipc-infra` by running: + +```shell +./bin/ipc-infra/run-root-docker-1val.sh +``` + +For instance, running `./bin/ipc-infra/run-root-docker-1val.sh 1235 1379` will run a rootnet daemon listening at `localhost:1235`, and a single validator mining in the rootnet listening through its libp2p host in `localhost:1379`. The end of the log in the execution of this script should look something like: + +```plaintext +>>> Root daemon running in container: 84711d67cf162e30747c4525d69728c4dea8c6b4b35cd89f6d0947fee14bf908 +>>> Token to /root daemon: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJBbGxvdyI6WyJyZWFkIiwid3JpdGUiLCJzaWduIiwiYWRtaW4iXX0.j94YYOr8_AWhGGHQd0q8JuQVuNhJA017SK9EUkqDOO0 +>>> Default wallet: t1cp4q4lqsdhob23ysywffg2tvbmar5cshia4rweq +``` + +This information will be relevant to configure our agent to connect to this rootnet node. For this, the `config.toml` section should be updated accordingly. In the above case, we need to set the endpoint of our rootnet node to be `127.0.0.1:1235`, we need to set `auth_token` to the one provided by the script, and the default account, for instance, the one provided by the script (although we could use ant other). + +The configuration for our rootnet should look therefore like this: + +```toml +[[subnets]] +id = "/root" +gateway_addr = "t064" +network_name = "root" +jsonrpc_api_http = "http://127.0.0.1:1235/rpc/v1" +auth_token = "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJBbGxvdyI6WyJyZWFkIiwid3JpdGUiLCJzaWduIiwiYWRtaW4iXX0.j94YYOr8_AWhGGHQd0q8JuQVuNhJA017SK9EUkqDOO0" +accounts = ["t1cp4q4lqsdhob23ysywffg2tvbmar5cshia4rweq"] +``` + +{% hint style="warning" %} +If you are already running the daemon, changes in the config file are only picked up after running `./bin/ipc-agent config reload` so be sure to run it after editing your config. +{% endhint %} + +Finally, to test if the connection to the rootnet has been successful, we can for instance try to create a new wallet in the rootnet: + +```shell +./bin/ipc-agent wallet new --key-type=bls +``` + +### Running a subnet + +To spawn a new subnet, our IPC agent should be connected to at least the subnet of the parent we want to spawn the subnet from. You can refer to the previous section for information on how to run or connect to a rootnet. This instructions will assume the deployment of a subnet from `/root`, but the steps are equivalent for any other parent subnet. + +#### Spawn subnet actor + +To run a subnet the first thing is to configure and create the subnet actor that will govern the subnet’s operation: + +```shell +./bin/ipc-agent subnet create -p -n --min-validator-stake 1 --min-validators --bottomup-check-period --topdown-check-period + +# Sample command execution +./bin/ipc-agent subnet create -p /root -n test --min-validator-stake 1 \ +--min-validators 0 --bottomup-check-period 10 --topdown-check-period 10 + +[2023-03-21T09:32:58Z INFO ipc_agent::cli::commands::manager::create] created subnet actor with id: /root/t01002 +``` + +This command deploys a subnet actor for a new subnet from the `root`, with a human-readable name `test`, that requires at least `1` validator to join the subnet to be able to mine new blocks, and with a checkpointing period to the parent of `10` blocks. We can see that the output of this command is the ID of the new subnet. + +#### Exporting wallet keys + +In order to run a validator in a subnet, we’ll need a set of keys to handle that validator. To export the validator key from a wallet that may live in another network into a file (like the wallet address we are using in the rootnet), we can use the following Lotus command: + +```shell +eudico wallet export --lotus-json > +``` + +For example: + +```shell +eudico wallet export --lotus-json t1cp4q4lqsdhob23ysywffg2tvbmar5cshia4rweq > ~/.ipc-agent/wallet.key +``` + +If your daemon is running on a docker container, you can get the container id (provided also in the output of the infra scripts), and run the following command above inside a container outputting the exported private key into a file locally: + +```shell +docker exec -it eudico wallet export --lotus-json > ~/.ipc-agent/wallet.key +``` + +For example: + +```shell +docker exec -it 84711d67cf162e30747c4525d69728c4dea8c6b4b35cd89f6d0947fee14bf908 eudico wallet export --lotus-json t1cp4q4lqsdhob23ysywffg2tvbmar5cshia4rweq > ~/.ipc-agent/wallet.key +``` + +Let’s illustrate the flow by creating a new wallet in our recently deployed root and exporting the keys. + +```shell +# Create the new wallet +./bin/ipc-agent wallet new --key-type=secp256k1 +[2023-03-29T09:32:52Z INFO ipc_agent::cli::commands::manager::wallet] created new wallet with address WalletNewResponse { address: "t17rnww5qirr2fh5uiqy6fyi6ix7otwjzgu6pgpey" } in subnet "/root" + +# Export the created wallet into ipc-agent +docker exec -it eudico wallet export --lotus-json > + +# Sample execution for the address created above +docker exec -it 84711d67cf162e30747c4525d69728c4dea8c6b4b35cd89f6d0947fee14bf908 eudico wallet export --lotus-json t17rnww5qirr2fh5uiqy6fyi6ix7otwjzgu6pgpey > ~/.ipc-agent/wallet.key +``` + +#### Deploy subnet daemon + +Before joining a new subnet, our node for that subnet should be initialized, because as part of the joining process we would need to provide information about our validator network address, so other validators know how to dial them. For the deployment of subnet daemons we also provide a convenient infra script: + +```shell +./bin/ipc-infra/run-subnet-docker.sh + +# Sample execution +./bin/ipc-infra/run-subnet-docker.sh 1239 1349 /root/t01002 ~/.ipc-agent/wallet.key +``` + +{% hint style="danger" %} +This script doesn’t support the use of relative paths for the wallet path. +{% endhint %} + +The end of the log of the execution of this script provides a bit more of information than the previous one as it is implemented to be used for production deployments: + +```shell +>>> Subnet /root/t01002 daemon running in container: 22312347b743f1e95e50a31c1f47736580c9a84819f41cb4ed3d80161a0d750f +>>> Token to /root/t01002 daemon: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJBbGxvdyI6WyJyZWFkIiwid3JpdGUiLCJzaWduIiwiYWRtaW4iXX0.TnoDqZJ1fqdkr_oCHFEXvdwU6kYR7Va_ALyEuoPnksA +>>> Default wallet: t1cp4q4lqsdhob23ysywffg2tvbmar5cshia4rweq +>>> Subnet subnet validator info: +t1cp4q4lqsdhob23ysywffg2tvbmar5cshia4rweq@/ip4/172.17.0.3/udp/1348/quic/p2p/12D3KooWN5hbWkCxwvrX9xYxMwFbWm2Jpa1o4qhwifmS t1cp4q4lqsdhob23ysywffg2tvbmar5cshia4rweq@/ip4/127.0.0.1/udp/1348/quic/p2p/12D3KooWN5hbWkCxwvrX9xYxMwFbWm2Jpa1o4qhwifmS t1cp4q4lqsdhob23ysywffg2tvbmar5cshia4rweq@/ip4/172.17.0.3/tcp/1347/p2p/12D3KooWN5hbWkCxwvrX9xYxMwFbWm2Jpa1o4qhwifmSw3Fb t1cp4q4lqsdhob23ysywffg2tvbmar5cshia4rweq@/ip4/127.0.0.1/tcp/1347/p2p/12D3KooWN5hbWkCxwvrX9xYxMwFbWm2Jpa1o4qhwifmSw3FbaVcL +>>> API listening in host port 1239 +>>> Validator listening in host port 1349 +``` + +The validator address specified here should be the same as the one that will be used in the next step to join the subnet. + +This log provides information about the API and auth tokens for the daemon, default validator wallet used, the multiaddresses where the validator is listening, etc. To configure our IPC agent with this subnet daemon, we need to once again update our IPC agent with the relevant information. In this case, for the sample execution above we need to add the following section to the end of our config file: + +```toml +[[subnets]] +id = "/root/t01002" +gateway_addr = "t064" +network_name = "test" +jsonrpc_api_http = "http://127.0.0.1:1239/rpc/v1" +auth_token = "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJBbGxvdyI6WyJyZWFkIiwid3JpdGUiLCJzaWduIiwiYWRtaW4iXX0.TnoDqZJ1fqdkr_oCHFEXvdwU6kYR7Va_ALyEuoPnksA" +accounts = ["t1cp4q4lqsdhob23ysywffg2tvbmar5cshia4rweq"] +``` + +As always, remember to run `./bin/ipc-agent config reload` for changes in the config of the agent to be picked up by the daemon. + +#### Joining a subnet + +With the daemon for the subnet deployed, we can join the subnet: + +```shell +./bin/ipc-agent subnet join --subnet= --collateral= --validator-net-addr= +``` + +For example: + +```bash +./bin/ipc-agent subnet join --subnet=/root/t01002 --collateral=2 --validator-net-addr="GET_ADDRESS_FROM_SCRIPT" +``` + +This command specifies the subnet to join, the amount of collateral to provide and the validator net address used by other validators to dial them. We can pick up this information from the execution of the script above or running `eudico mir validator config validator-addr` from your deployment. Bear in mind that the multiaddress provided for the validator needs to be accessible publicly by other validators. According to the deployment used you may need to tweak the IP addresses of the multiaddresses and the ones provided by these scripts and commands won’t be usable out-of-the-box. + +For instance, in the example above, we are using the DNS endpoint `/dns/host.docker.internal/` so other Docker containers for the subnet deployed in the host machine know how to contact the validator. + +As a sanity-check that we have joined the subnet successfully and that we provided enough collateral to register the subnet to IPC, we can list the child subnets of our parent with the following command: + +```shell +./bin/ipc-agent subnet list --gateway-address= --subnet= + +``` + +For example: + +```bash +./bin/ipc-agent subnet list --gateway-address=t064 --subnet=/root + +# [2023-03-30T17:00:25Z INFO ipc_agent::cli::commands::manager::list_subnets] /root/t01003 - status: 0, collateral: 2 FIL, circ.supply: 0.0 FIL +``` + +In the current implementation of IPC the gateway actor is deployed as a system actor on the default address `t064`, so whenever one of the IPC commands requests the address of the gateway actor you can use that value. + +#### Mining in a subnet + +With our subnet daemon deployed, and having joined the network, as the minimum number of validators we set for our subnet is 0, we can start mining and creating new blocks in the subnet. Doing so is a simple as running the following script using as an argument the container of our subnet node: + +```shell +./bin/ipc-infra/mine-subnet.sh +``` + +For example: + +```bash +./bin/ipc-infra/mine-subnet.sh 84711d67cf162e30747c4525d69728c4dea8c6b4b35cd89f6d0947fee14bf908 +``` + +The mining process is currently run in the foreground in interactive mode. Consider using `nohup ./bin/ipc-infra/mine-subnet.sh` or tmux to run the process in the background and redirect the logs to some file. + +#### Changing subnet validator network address + +It may be the case that while joining the subnet, you didn’t set the multiaddress for your validator correctly and you need to update it. You’ll realize that the network address of your validator is not configured correctly, because your agent throws an error when trying to connect to your subnet node, or starting the validator in your subnet throws a network-related error. + +Changing the validator is as simple as running the following command: + +```shell +./bin/ipc-agent subnet set-validator-net-addr --subnet= --validator-net-addr= +``` + +For example: + +```bash +./bin/ipc-agent subnet set-validator-net-addr --subnet=/root/t01002 --validator-net-addr="/dns/host.docker.internal/tcp/1349/p2p/12D3KooWDeN3bTvZEH11s9Gq5bDeZZLKgRZiMDcy2KmA6mUaT9KE" +``` + +#### Committing checkpoints from a subnet + +Subnets are periodically committing checkpoints to their parent every `check-period` (parameter defined when creating the subnet). When you configure the connection to your child subnet in the agent config, and `config reload`, your agent should automatically start the process responsible for creating the checkpoints and submitting them to the parent. This process will only commit new subnet if you are a validator in that subnet. If the agent has spawned successfully the checkpointing process, you should start seeing every now and then these logs: + +```plaintext +[2023-03-29T09:52:48Z INFO ipc_agent::manager::checkpoint] Submitting checkpoint for account t1cp4q4lqsdhob23ysywffg2tvb +[2023-03-29T09:52:55Z INFO ipc_agent::manager::checkpoint] successfully published checkpoint submission for epoch 50 +``` + +It is common for the checkpointing process to fail if while configuring a child subnet: either because the auth token is not correct, or because no wallet addresses have been configured in the subnet, etc. If this happens, running `./bin/ipc-agent config reload` will restart the checkpoint manager and pick up the latest config values. Whenever you see an error in the checkpointing process, check that your subnet’s configuration is correct and `config reload` to restart the process. + +Finally, if you want to inspect the information of a range of checkpoints committed in the parent for a subnet, you can use the `list-bottomup` command provided by the agent as follows: + +```shell +# List checkpoints between two epochs for a subnet +./bin/ipc-agent checkpoint list-bottomup --from-epoch= --to-epoch= --subnet= + +``` + +For example: + +```bash +./bin/ipc-agent checkpoint list-bottomup --from-epoch=0 --to-epoch=100 --subnet=/ +root/t01002 + +# [2023-03-29T12:43:42Z INFO ipc_agent::cli::commands::manager::list_checkpoints] epoch 0 - prev_check={"/":"bafy2bzacedkoa623kvi5gfis2yks7xxjl73vg7xwbojz4tpq63dd5jpfz757i"}, cross_msgs=null, child_checks=null +# [2023-03-29T12:43:42Z INFO ipc_agent::cli::commands::manager::list_checkpoints] epoch 10 - prev_check={"/":"bafy2bzacecsatvda6lodrorh7y7foxjt3a2dexxx5jiyvtl7gimrrvywb7l5m"}, cross_msgs=null, child_checks=null +# [2023-03-29T12:43:42Z INFO ipc_agent::cli::commands::manager::list_checkpoints] epoch 30 - prev_check={"/":"bafy2bzaceauzdx22hna4e4cqf55jqmd64a4fx72sxprzj72qhrwuxhdl7zexu"}, cross_msgs=null, child_checks=null +``` + +#### Sending funds in a subnet + +The agent provides a command to conveniently exchange funds between addresses of the same subnet. This can be achieved through the following command: + +```shell +./bin/ipc-agent subnet send-value --subnet= --to= +``` + +For example: + +``` +./bin/ipc-agent subnet send-value --subnet=/root/t01002 --to=t1xbevqterae2tanmh2kaqksnoacflrv6w2dflq4i 10 +``` + +#### Leaving a subnet + +To leave a subnet, the following agent command can be used: + +```shell +./bin/ipc-agent subnet leave --subnet= +``` + +For example: + +```bash +./bin/ipc-agent subnet leave --subnet=/root/t01002 +``` + +Leaving a subnet will release the collateral for the validator and remove all the validation rights from its account. This means that if you have a validator running in that subnet, its validation process will immediately terminate. + +#### Importing a wallet to a subnet node + +Depending on if the subnet is running inside a docker container or not, we can use the following commands to import a wallet to a subnet node: + +```shell +# Importing directly into the node +eudico wallet import --lotus-json +``` + +```bash +# Importing directly into a docker container +docker cp : +``` + +```bash +# Copy the wallet key inside the container +docker exec -it sh -c "./eudico wallet import --format=json-lotus " +``` + +```bash +# Sample execution +docker cp ~/.ipc-agent/t1ivy6mo2ofxw4fdmft22nel66w63fb7cuyslm4cy.key 91d2af805346:/input.key +docker exec -it 91d2af805346 sh -c "eudico wallet import --format=json-lotus input.key" +``` + +#### Running a subnet with several validators + +In this section, we will deploy a subnet where the IPC agent is responsible for handling more than one validator in the subnet. Throughout this guide, we use the `ipc-infra` scripts to deploy the nodes in Docker containers, but a similar steps could be used to deploy the nodes on bare-metal or any other runtime. + +For the rest of this tutorial, we’ll assume that you have your agent already configured and interacting with a rootnet. We are going to deploy a subnet with 5 validators. The first thing we’ll need to do is creating a new wallet for every validator we want to run. We can do this directly through the agent with the following command: + +```shell +./bin/ipc-agent wallet new --key-type=secp256k1 +``` + +We also need to provide with some funds our wallets so they can put collateral to join the subnet. According to the rootnet you are connected to, you may need to get some funds from the faucet, or send some from your main wallet. Funds can be send from your main wallet also through the agent with: + +```shell +./bin/ipc-agent subnet send-value --subnet=/root --to= +``` + +With this, we can already create the subnet with `/root` as its parent. We are going to set the `--min-validators 5` so no new blocks can be created without this number of validators in the subnet. + +```shell +# Creating a sample subnet with 5 as the minimum number of validators. +./bin/ipc-agent subnet create -p /root -n test --min-validator-stake 1 --min-validators 5 --bottomup-check-period 10 --topdown-check-period 10 +``` + +#### Deploying the infrastructure + +In order to deploy the 5 validators for the subnet, we will have to first export the keys from our root node so we can import them to our validators. Depending on how you are running your rootnet node you’ll have to make a call to the docker container, or your nodes API. + +With the five keys conveniently exported, we can deploy the subnet nodes using the `infra-scripts`. The following code snippet showcases the deployment of five sample nodes. Note that each node should be importing a different wallet key for their validator, and should be exposing different ports for their API and validators: + +```shell +./bin/ipc-infra/run-subnet-docker.sh 1240 1359 /root/t01002 ~/.ipc-agent/wallet1.key +./bin/ipc-infra/run-subnet-docker.sh 1250 1369 /root/t01002 ~/.ipc-agent/wallet2.key +./bin/ipc-infra/run-subnet-docker.sh 1280 1379 /root/t01002 ~/.ipc-agent/wallet3.key +./bin/ipc-infra/run-subnet-docker.sh 1270 1389 /root/t01002 ~/.ipc-agent/wallet4.key +./bin/ipc-infra/run-subnet-docker.sh 1280 1399 /root/t01002 ~/.ipc-agent/wallet5.key +``` + +If the deployment is successful each of these nodes should return the following output at the end of their logs. Note down this information somewhere as we will need it to conveniently join our validators to the subnet. + +```plaintext +>>> Subnet /root/t01002 daemon running in container: 91d2af80534665a8d9a20127e480c16136d352a79563e74ee3c5497d50b9eda8 (friendly name: ipc_root_t01002_1240) +>>> Token to /root/t01002 daemon: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJBbGxvdyI6WyJyZWFkIiwid3JpdGUiLCJzaWduIiwiYWRtaW4iXX0.JTiumQwFIutkTb0gUC5JWTATs-lUvDaopEDE0ewgzLk +>>> Default wallet: t1ivy6mo2ofxw4fdmft22nel66w63fb7cuyslm4cy +>>> Subnet subnet validator info: +t1ivy6mo2ofxw4fdmft22nel66w63fb7cuyslm4cy@/ip4/172.17.0.4/udp/1348/quic/p2p/12D3KooWEJXcSPw6Yv4jDk52xvp2rdeG3J6jCPX9AgBJE2mRCVoR +t1ivy6mo2ofxw4fdmft22nel66w63fb7cuyslm4cy@/ip4/127.0.0.1/udp/1348/quic/p2p/12D3KooWEJXcSPw6Yv4jDk52xvp2rdeG3J6jCPX9AgBJE2mRCVoR +t1ivy6mo2ofxw4fdmft22nel66w63fb7cuyslm4cy@/ip4/172.17.0.4/tcp/1347/p2p/12D3KooWEJXcSPw6Yv4jDk52xvp2rdeG3J6jCPX9AgBJE2mRCVoR +t1ivy6mo2ofxw4fdmft22nel66w63fb7cuyslm4cy@/ip4/127.0.0.1/tcp/1347/p2p/12D3KooWEJXcSPw6Yv4jDk52xvp2rdeG3J6jCPX9AgBJE2mRCVoR +>>> API listening in host port 1240 +>>> Validator listening in host port 1359 +``` + +#### Configuring the agent + +To configure the agent for its use with all the validators, we need to connect to the RPC API of one of the validators, and import all of the wallets of the validators in that node, so the agent is able through the same API to act on behalf of any validator. + +Here’s an example of the configuration connecting to the RPC of the first validator, and configuring all the wallets for the validators in the subnet. + +```toml +[[subnets]] +id = "/root/t01002" +gateway_addr = "t064" +network_name = "test" +jsonrpc_api_http = "http://127.0.0.1:1240/rpc/v1" +auth_token = "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJBbGxvdyI6WyJyZWFkIiwid3JpdGUiLCJzaWduIiwiYWRtaW4iXX0.JTiumQwFIutkTb0gUC5JWTATs-lUvDaopEDE0ewgzLk" +accounts = ["t1ivy6mo2ofxw4fdmft22nel66w63fb7cuyslm4cy", "t1cp4q4lqsdhob23ysywffg2tvbmar5cshia4rweq", "t1nv5jrdxk4ljzndaecfjgmu35k6iz54pkufktvua", "t1pr3qzqieikp33pfdaygwkwt5v35a5ljsxsu64xq", "t1pmxk3nhg2u2ge7ioilrk7c5rmdmmbgpazipvzyy"] +``` + +Remember to run `./bin/ipc-agent config reload` for your agent to pick up the latest changes for the config. + +#### Joining the subnet + +All the infrastructure for the subnet is now deployed, and we can join our validators to the subnet. For this, we need to send a `join` command from each of our validators from their validator wallet addresses providing the validators multiaddress. We can get the validator multiaddress from the output of the script we ran to deploy the infrastructure (or by running `eudico mir validator config validator-addr`). These scripts expose through docker the port for the TPC port of the libp2p host of the validator (if there is interest to use the UDP-based multiaddress drop an issue and we can update them accordingly). Hence, we need to choose from the available multiaddresses one that exposes a TCP connection. Finally, our validators are configured so their docker containers interact with each other through ports in the host machine, so instead of exposing an IP address for the multiaddress, the following DNS-based multiaddress needs to be used for all validators: `/dns/host.docker.internal/`. + +This is the command that needs to be executed for every validator to join the subnet: + +```shell +./bin/ipc-agent subnet join --from= --subnet=/root/t01002 --collateral= --validator-net-addr="/dns/host.docker.internal/tcp//p2p/" +``` + +For example: + +```bash +# Sample execution for the validator whose logs where shared above for 2FIL collateral +./bin/ipc-agent subnet join --from=t1ivy6mo2ofxw4fdmft22nel66w63fb7cuyslm4cy --subnet=/root/t01002 --collateral=2 --validator-net-addr="/dns/host.docker.internal/tcp/1359/p2p/12D3KooWEJXcSPw6Yv4jDk52xvp2rdeG3J6jCPX9AgBJE2mRCVoR +``` + +Remember doing the above step for the five validators. + +#### Mining in subnet + +We have everything in place now to start mining from all the validators. Mining is as simple as running the following script passing the container id for the validators: + +```shell +./bin/ipc-infra/mine-subnet.sh +``` + +The mining process is currently run in the foreground in interactive mode. Consider using `nohup ./bin/ipc-infra/mine-subnet.sh` or tmux to run the process in the background and redirect the logs to some file as handling the mining process of the five validators in the foreground may be quite cumbersome. + +### Troubleshooting + +#### I need to upgrade my IPC agent + +Sometimes, things break, and we’ll need to push a quick path to fix some bug. If this happens, and you need to upgrade your agent version, kill you agent daemon if you have any running, pull the latest changes from this repository, build the binary, and start your daemon again. This should pick up the latest version for the agent. In the future, we will provide a better way to upgrade your agent. + +```shell +# Pull latest changes +git pull + +# Build the agent +make build + +# Restart the daemon +./bin/ipc-agent daemon +``` + +#### The make install-infra command is not building the Eudico image + +`make install-infra` may fail and not build the `eudico` image if your system is not configured correctly. If this happens, you can always try to build the image yourself to have a finer-grain report of the issues to help you debug them. For this you can [follow these instructions](https://github.com/consensus-shipyard/lotus/blob/spacenet/scripts/ipc/README.md). + +High-level you just need to clone the [Eudico repository](https://github.com/consensus-shipyard/lotus), and run `docker build -t eudico .` in the root of the repository. + +#### My subnet node doesn’t start + +Either because the dockerized subnet node after running `./bin/ipc-infra/run-subnet-docker.sh` gets stuck waiting for the API to be started with the following message: + +```plaintext +Not online yet... (could not get API info for FullNode: could not get api endpoint: API not running (no endpoint)) +``` + +Or because when the script finishes no validator address has been reported as expected by the logs, the best way to debug this situation is to attach to the docker container and check the logs with the following command: + +```shell +docker exec -it bash +``` + +Once inside the container, run: + +```bash +tmux a +``` + +Generally, the issue is that: + +* You haven’t passed the validator key correctly and it couldn’t be imported. +* There was some network instability, and lotus parameters couldn’t be downloaded successfully. + +#### My agent is not submitting checkpoints after an error + +Try running `./bin/ipc-agent config reload`, this should pick up the latest config and restart all checkpointing processes.

These primitives and features include publicly verifiable cryptographic storage proofs, [cryptoeconomic mechanisms](https://filecoin.io/blog/filecoin-cryptoeconomic-constructions/), and a public blockchain. Filecoin provides these primitives to solve the really hard problem of creating a trustless decentralized storage network. + +On top of the core Filecoin protocol, there are a number of layer 2 solutions that enable a broad array of use cases and applications, many of which also use [IPFS](https://ipfs.tech). These solutions include [Powergate](https://docs.textile.io/powergate/), [Textile Hub](https://blog.textile.io/announcing-the-textile-protocol-hub/), and more. Using these solutions, any use case that can be built on top of IPFS can also be built on Filecoin! + +Some of the primary areas for development on Filecoin are: + +* Additional developer tools and layer-2 solutions and libraries that strengthen Filecoin as a developer platform and ecosystem. +* IPFS apps that rely on decentralized storage solutions and want a decentralized data persistence solution as well. +* Financial tools and services on Filecoin, like wallets, signing libraries, and more. +* Applications that use Filecoin’s publicly verifiable cryptographic proofs in order to provide trustless and timestamped guarantees of storage to their users. + +#### How can a website or app be free if it costs to retrieve data from the Filecoin network? + +Most websites and apps make money by displaying ads. This type of income-model could be replaced with a Filecoin incentivized retrieval setup, where users pay small amounts of FIL for whatever files they’re hoping to download. Several large datasets are hosted through Amazon’s _pay per download_ S3 buckets, which Filecoin retrieval could also easily augment or replace. + +#### How will Filecoin attract developers to use Filecoin for storage? + +It’s going to require a major shift in how we think about the internet. At the same time, it is a very exciting shift, and things are slowly heading that way. Browser vendors like Brave, Opera, and Firefox are investing into decentralized infrastructure. + +We think that the internet must return to its _decentralized roots_ to be resilient, robust, and efficient enough for the challenges of the next several decades. Early developers in the Filecoin ecosystem are those who believe in that same vision and potential for the internet, and we’re excited to work with them to build this space. + +#### What are the detailed parameters of Filecoin’s cryptoeconomics? + +We are still finalizing our cryptoeconomic parameters, and they will continue to evolve. + +Here is a blog about Filecoin economics from December 2020: [Filecoin network economics](https://filecoin.io/blog/posts/filecoin-network-economics/). + +#### How expensive will Filecoin storage be at launch? + +As Filecoin is a free market, the price will be determined by a number of variables related to the supply and demand for storage. It’s difficult to predict before launch. However, a few design elements of the network help support inexpensive storage. + +Along with revenue from active storage deals, Storage Miners receive block rewards, where the expected value of winning a given block reward is proportional to the amount of storage they have on the network. These block rewards are weighted heavily towards the early days of the network (with the frequency of block rewards exponentially decaying over time). As a result, Storage Miners are relatively incentivized to charge less for storage to win more deals, which would increase their expected block reward. + +Further, Filecoin introduces a concept called _Verified Clients_, where clients can be verified to actually be storing useful data. Storage Miners who store data from _Verified Clients_ also increase their expected block reward. Anyone running a Filecoin-backed IPFS Pinning Services should qualify as a _Verified Client_. We do not have the process of verification finalized, but we expect it to be similar to submitting a GitHub profile. + +#### Will it be cheaper to store data on Filecoin than other centralized cloud services? + +Filecoin creates a hyper-competitive market for data storage. There will be many storage providers offering many prices, rather than one fixed price on the network. We expect Filecoin’s permissionless model and low barriers to entry to result in some very efficient operations and low-priced storage, but it’s impossible to say what exact prices will be until the network is live. + +#### What happens to the existing content on IPFS once Filecoin launches? What if nodes continue to host content for free and undermine the Filecoin incentive layer? + +IPFS will continue to exist as it is, enhanced with Filecoin nodes. There are many use cases that require no financial incentive. Think of it like IPFS is HTTP, and Filecoin is a storage cloud-like S3 – only a fraction of IPFS content will be there. + +People with unused storage who want to earn monetary rewards should pledge that storage to Filecoin, and clients who want guaranteed storage should store that data with Filecoin storage providers. + +#### Lotus or Venus, which is better for storage providers? + +Lotus is the primary reference implementation for the Filecoin protocol. At this stage, we would recommend most storage providers use lotus to participate in the Filecoin network. + +#### What is your recommendation on the right hardware to use? + +While the Filecoin team does not recommend a specific hardware configuration, we document various setups [here](../../storage-providers/infrastructure/). Additionally, [this guide to storage mining](../../storage-providers/basics/quickstart-guide.md) details hardware considerations and setups for storage providers. However, it is likely that there are more efficient setups, and we strongly encourage storage providers to test and experiment to find the best combinations. + +#### We are worried about the ability of our network to handle the additional overhead of running a Filecoin node and still provide fast services for our customers. What are the computational demands of a Lotus node? Are there any metrics for node performance given various requirements? + +For information on Lotus requirements, see [Prerequisites > Minimal requirements](https://lotus.filecoin.io/lotus/install/prerequisites/#minimal-requirements). + +For information on Lotus full nodes and lite nodes, see [Types of nodes](https://lotus.filecoin.io/lotus/get-started/use-cases/). + +#### We bought a lot of hard drives of data through the Discover project. When will they be shipped to China? + +There are a number of details that are still being finalized between the verified deals construction and the associated cryptoeconomic parameters. + +Our aim is to allow these details to finalize before shipping, but given timelines, we’re considering enabling teams to take receipt of these drives before the parameters are set. We will publish updates on the status of the Discover project on the Filecoin blog. + +#### Do Filecoin storage providers need a fixed IP? + +For mainnet, you will need a public IP address, but it doesn’t need to be fixed (just accessible). + +#### What if we lost a sector accidentally, is there any way to fix that? + +If you lost the data itself, then no, there’s no way to recover that, and you will be slashed for it. If the data itself is recoverable, though (say you just missed a _WindowPoSt_), then the Recovery process will let you regain the sector. + +#### Has Filecoin confirmed the use of the SDR algorithm? Is there any evidence of malicious construction? + +SDR ([Stacked DRG PoRep](https://spec.filecoin.io/algorithms/porep-old/stacked\_drg/#section-algorithms.porep-old.stacked\_drg)) is confirmed and used, and we have no evidence of malicious construction. The algorithm is also going through both internal and external security audits. + +If you have any information about any potential security problem or malicious construction, reach out to our team at [security@filecoin.org](mailto:security@filecoin.org). + +#### How likely is it that the Filecoin protocol will switch to the NSE Proof-of-Replication construction later? + +Native storage extension (NSE) is one of the best candidates for a proof upgrade, and teams are working on implementation. But there are other candidates too, which are promising as well. It may be that another algorithm ends up better than NSE – we don’t know yet. Proof upgrades will arrive after the mainnet launch and will coexist. + +AMD may be optimal hardware for SDR. You can [see this description](https://github.com/filecoin-project/lotus/blob/master/documentation/en/sealing-procs.md) for more information on why. + +#### How are you working on bootstrapping the demand side of the marketplace? The Discover program is nice, but who is the target market for users, and how do you get them? + +In addition to [Filecoin Discover](https://filecoin.io/blog/posts/introducing-filecoin-discover/), a number of groups are actively building tools and services to support the adoption of the Filecoin network with developers and clients. For example, check out the recordings from our [Virtual Community Meetup](https://filecoin.io/blog/filecoin-virtual-community-meetup-recap/) to see updates about Textile Powergate and Starling Storage. You can also read more about some of the teams building on Filecoin through HackFS in our [HackFS Week 1 Recap](https://filecoin.io/blog/hackfs-teams-vol-1/). + +#### Does Filecoin have an implementation of client and storage provider order matching through order books? + +There will be off-chain [order books](https://www.investopedia.com/terms/o/order-book.asp) and storage provider marketplaces – some are in development now from some teams. They will work mostly off-chain because transactions per second on-chain are not enough for the volume of usage we expect on Filecoin. These order books build on the basic deal-flow on-chain. These order books will arrive in their own development trajectory – most likely around or soon after the mainnet launch. + +#### Why does Filecoin mining work best on AMD? + +Currently, Filecoin’s Proof of Replication (PoRep) prefers to be run on AMD processors. See this description of Filecoin sealing for more information. More accurately, it runs much slower on Intel CPUs. It runs competitively fast on some ARM processors, like the ones in newer Samsung phones, but they lack the RAM to seal the larger sector sizes. The main reason that we see this benefit on AMD processors is due to their implementation of the SHA hardware instructions. + +#### What do storage providers have to do to change a committed capacity (CC) sector into a “real-data” sector? + +Storage providers will publish storage deals that they will upgrade the CC sector with, announce to the chain that they are doing an upgrade, and prove to the chain that a new sector has been sealed correctly. We expect to evolve and make this cheaper and more attractive over time after the mainnet launch. + +#### What does “terminating a sector” mean? + +When a committed capacity sector is added to the chain, it can upgrade to a sector with deals, extend its lifetime, or terminate through either faults or voluntary actions. While we don’t expect this to happen very often on mainnet, a storage provider may deem it rational to terminate their promise to the network and their clients, and accept a penalty for doing so. + +#### Does the committed capacity sector still need to be sealed before it upgrades to one with real data? + +For the first iteration of the protocol, yes. We have plans to make it cheaper and more economically attractive after mainnet with no resealing required and other perks. + +#### What’s the minimum time period for the storage contract between the provider and the buyer? + +The minimum duration for a deal is set in the storage provider’s ask. There’s also a practical limitation because sectors have a minimum duration (currently 180 days). + +#### After I made a deal with a storage provider and sent my data to them, how exactly is the data supposed to be recoverable and healable if that storage provider goes down? + +Automatic repair of faulted data is a feature we’ve pushed off until after the mainnet launch. For now, the way to ensure resiliency is to store your data with multiple storage providers, to gain some level of redundancy. If you want to learn more about how we are thinking about repair in the future, [here are some notes](https://github.com/filecoin-project/specs/pull/245/files). + +#### How do I know that my storage provider will not charge prohibitively high costs for data retrieval? + +To avoid extortion, always ensure you store your data with a fairly decentralized set of storage providers (and note: it’s pretty difficult for a storage provider to be sure they are the only person storing a particular piece of data, especially if you encrypt the data). + +Storage providers currently provide a ‘dumb box’ interface and will serve anyone any data they have. Maybe in the future, storage providers will offer access control lists (ACLs) and logins and such, but that requires that you trust the storage provider. The recommended (and safest) approach here is to encrypt data you don’t want others to see yourself before storing it. + +#### How do you update data stored on Filecoin? + +We have some really good ideas around ‘warm’ storage (that is mutable and provable) that we will probably implement in the near future. But for now, your app will have to treat Filecoin as an append-only log. If you want to change your data, you just write new data. + +‘Warm’ storage can be done with a small amount of trust, where you make a deal with a storage provider with a start date quite far in the future. The storage provider can choose to store your data in a sector now (but they won’t get paid for proving it until the actual start date), or they can hold it for you (and even send you proofs of it on request), and you can then send them new data to overwrite it, along with a new storage deal that overwrites the previous one. + +There’s a pretty large design space here, and we can do a bunch of different things depending on the levels of trust involved, the price sensitivity, and the frequency of updates clients desire. + +#### Who will be selected to be verifiers to verify clients on the network? + +Notaries, selected through an application process, serve as fiduciaries for the Filecoin Network and are responsible for allocating DataCap to clients with valuable storage use cases. + +See [Filecoin Plus](../how-storage-works/filecoin-plus.md). + +#### Will the existence of Filecoin mining pools lead to centralized storage and away from the vision of distributed storage? + +No – Filecoin creates a decentralized storage network in part by massively decreasing the barrier to entry to becoming a storage provider. Even if there were some large pools, anyone can join the network and provide storage with just a modest hardware purchase, and we expect clients to store their files with many diverse storage providers. + +Also, note that world location matters for mining: many clients will prefer storage providers in specific regions of the world, so this enables lots of storage providers to succeed across the world, where there is storage demand. + +#### Even though Filecoin will be backed up to our normal IPFS pinning layer, we still need to know how quickly we can access data from the Filecoin network. How fast will retrieval be from the Filecoin network? + +If you are retrieving your data from IPFS or a remote pinning layer, retrieval should take on the order of milliseconds to seconds in the worst case. Our latest tests for retrieval from the Filecoin network directly show that a sealed sector holding data takes \~1 hour to unseal. 1-5 hours is our best real-world estimate to go from sector unsealing to delivery of the data. If you need faster data retrieval for your application, we recommend building on Powergate or an FPS. diff --git a/basics/project-and-community/related-projects.md b/basics/project-and-community/related-projects.md new file mode 100644 index 000000000..3bebca5a7 --- /dev/null +++ b/basics/project-and-community/related-projects.md @@ -0,0 +1,28 @@ +--- +description: >- + Filecoin is a highly modular project that is itself made out of many different + protocols and tools.

They do not need to convince the reader of something or explain a concept. Walkthroughs are a list of steps the reader must follow to achieve a process or function. + +The vast majority of documentation within the Filecoin documentation project falls under the _Walkthrough_ category. Walkthroughs are generally quite short, have a neutral tone, and teach the reader how to achieve a particular process or function. They present the reader with concrete steps on where to go, what to type, and things they should click on. There is little to no _conceptual_ information within walkthroughs. + +**Goals** + +Use the following goals when writing walkthroughs: + +
    GoalKeywordExplanation
    AudienceGeneralEasy for anyone to read with minimal effort.
    FormalityNeutralSlang is restricted, but standard casual expressions are allowed.
    DomainTechnicalAcronyms and tech-specific language is used and expected.
    ToneNeutralWriting contains little to no emotion.
    IntentInstructTell the reader how to do something.
    + +**Function or process** + +The end goal of a walkthrough is for the reader to achieve a very particular function. _Installing the Filecoin Desktop application_ is an example. Following this walkthrough isn’t going to teach the reader much about working with the decentralized web or what Filecoin is. Still, by the end, they’ll have the Filecoin Desktop application installed on their computer. + +**Short length** + +Since walkthroughs cover one particular function or process, they tend to be quite short. The estimated reading time of a walkthrough is somewhere between 2 and 10 minutes. Most of the time, the most critical content in a walkthrough is presented in a numbered list. Images and GIFs can help the reader understand what they should be doing. + +If a walkthrough is converted into a video, that video should be no longer than 5 minutes. + +**Walkthrough structure** + +Walkthroughs are split into three major sections: + +1. What we’re about to do. +2. The steps we need to do. +3. Summary of what we just did, and potential next steps. + +#### Conceptual articles + +Articles are written with the intent to inform and explain something. These articles don’t contain any steps or actions that the reader has to perform _right now_. + +These articles are vastly different in tone when compared to walkthroughs. Some topics and concepts can be challenging to understand, so creative writing and interesting diagrams are highly sought-after for these articles. Whatever writers can do to make a subject more understandable, the better. + +**Article goals** + +Use the following goals when writing conceptual articles: + +
    GoalKeywordExplanation
    AudienceKnowledgeableRequires a certain amount of focus to understand.
    FormalityNeutralSlang is restricted, but standard casual expressions are allowed.
    DomainAnyUsually technical, but depends on the article.
    ToneConfident and friendlyThe reader must feel confident that the writer knows what they’re talking about.
    IntentDescribeTell the reader why something does the thing that it does, or why it exists.
    + +**Article structure** + +Articles are separated into five major sections: + +1. Introduction to the thing we’re about to explain. +2. What the thing is. +3. Why it’s essential. +4. What other topics it relates to. +5. Summary review of what we just read. + +#### Tutorials + +When writing a tutorial, you’re teaching a reader how to achieve a complex end-goal. Tutorials are a mix of walkthroughs and conceptual articles. Most tutorials will span several pages, and contain multiple walkthroughs within them. + +Take the hypothetical tutorial _Get up and running with Filecoin_, for example. This tutorial will likely have the following pages: + +1. A brief introduction to what Filecoin is. +2. Choose and install a command line client. +3. Understanding storage deals. +4. Import and store a file. + +Pages `1` and `3` are conceptual articles, describing particular design patterns and ideas to the reader. All the other pages are walkthroughs instructing the user how to perform one specific action. + +When designing a tutorial, keep in mind the walkthroughs and articles that already exist, and note down any additional content items that would need to be completed before creating the tutorial. + +### Grammar and formatting + +Here are some language-specific rules that the Filecoin documentation follows. If you use a writing service like [Grammarly](https://www.grammarly.com/), most of these rules are turned on by default. + +#### American English + +While Filecoin is a global project, the fact is that American English is the most commonly used _style_ of English used today. With that in mind, when writing content for the Filecoin project, use American English spelling. The basic rules for converting other styles of English into American English are: + +1. Swap the `s` for a `z` in words like _categorize_ and _pluralize_. +2. Remove the `u` from words like _color_ and _honor_. +3. Swap `tre` for `ter` in words like _center_. + +#### The Oxford comma + +In a list of three or more items, follow each item except the last with a comma `,`: + +| Use | Don’t use | +| ----------------------------- | ---------------------------- | +| One, two, three, and four. | One, two, three and four. | +| Henry, Elizabeth, and George. | Henry, Elizabeth and George. | + +#### References to Filecoin + +As a proper noun, the name “Filecoin” (capitalized) should be used only to refer to the overarching project, to the protocol, or to the project’s canonical network: + +> Filecoin \[the project] has attracted contributors from around the globe! Filecoin \[the protocol] rewards contributions of data storage instead of computation! Filecoin \[the network] is currently storing 50 PiB of data! + +The name can also be used as an adjective: + +> The Filecoin ecosystem is thriving! I love contributing to Filecoin documentation! + +When referring to the token used as Filecoin’s currency, the name `FIL`, is preferred. It is alternatively denoted by the Unicode symbol for an integral with a double stroke ⨎: + +* Unit prefix: **100 FIL**. +* Symbol prefix: **⨎ 100**. + +The smallest and most common denomination of FIL is the `attoFIL` (10^-18 FIL). + +> The collateral for this storage deal is 5 FIL. I generated ⨎100 as a storage provider last month! + +Examples of discouraged usage: + +> Filecoin rewards storage providers with Filecoin. There are many ways to participate in the filecoin community. My wallet has thirty filecoins. + +Consistency in the usage of these terms helps keep these various concepts distinct. + +#### References to Lotus + +Lotus is the main implementation of Filecoin. As such, it is frequently referenced in the Filecoin documentation. When referring to the Lotus implementation, use a capital _L_. A lowercase _l_ should only be used when referring to the Lotus executable commands such as `lotus daemon`. Lotus executable commands should always be within code blocks: + +````markdown +1. Start the Lotus daemon: + + ```shell + lotus daemon + ``` + +2. After your Lotus daemon has been running for a few minutes, use `lotus` to check the number of other peers that it is connected to in the Filecoin network: + + ```shell + lotus net peers + ``` +```` + +#### Acronyms + +If you have to use an acronym, spell the full phrase first and include the acronym in parentheses `()` the first time it is used in each document. Exception: This generally isn’t necessary for commonly-encountered acronyms like _IPFS_, unless writing for a stand-alone article that may not be presented alongside project documentation. + +> Virtual Machine (VM), Decentralized Web (DWeb). + +### Formatting + +How the Markdown syntax looks, and code formatting rules to follow. + +#### Syntax + +The Filecoin Docs project follows the _GitHub Flavoured Markdown_ syntax for markdown. This way, all articles display properly within GitHub itself. This gives readers the option to view articles on [the docs website](http://localhost:5000/o/NNmD4UvLc26b1TmEYgzE/s/ljEfPn4P3ow2x1OCSoi4/) or [its GitHub repo](https://github.com/filecoin-project/filecoin-docs). + +#### Rules + +We use the rules set out in the [VSCode Markdownlint](https://github.com/DavidAnson/vscode-markdownlint) extension. You can import these rules into any text editor like Vim or Sublime. All rules are listed [within the Markdownlint repository](https://github.com/DavidAnson/markdownlint/blob/master/doc/Rules.md). + +We highly recommend installing [VSCode](https://code.visualstudio.com/) with the [Markdownlint](https://github.com/DavidAnson/vscode-markdownlint) extension to help with your writing. The extension shows warnings within your markdown whenever your copy doesn’t conform to a rule. + +### Style + +The following rules explain how we organize and structure our writing. The rules outlined here are in addition to the [rules](https://github.com/DavidAnson/markdownlint/blob/master/doc/Rules.md) found within the [Markdownlinter extension](https://github.com/DavidAnson/vscode-markdownlint). + +#### Text + +The following rules apply to editing and styling text. + +**Titles** + +1. All titles follow sentence structure. Only _names_ and _places_ are capitalized, along with the first letter of the title. All other letters are lower-case: + +
    ## This is a title
+
+### Only capitalize names and places
+
+### The capital city of France is Paris
+
    + +2. Every article starts with a _front-matter_ title and description: + +```markdown +--- +title: Example article +description: This is a brief description that shows up in link teasers in services like Twitter and Slack. +--- + +## This is a subtitle + +Example body text. +``` + +In the above example `title:` serves as a `

    ` or `#` tag. There is only ever one title of this level in each article. + +3. Titles do not contain punctuation. If you have a question within your title, rephrase it as a statement: + +```markdown + +## What is Filecoin? + + +## Filecoin explained +``` + +**Bold text** + +Double asterisks `**` are used to define **boldface** text. Use bold text when the reader must interact with something displayed as text: buttons, hyperlinks, images with text in them, window names, and icons. + +```markdown +In the **Login** window, enter your email into the **Username** field and click **Sign in**. +``` + +**Italics** + +Underscores `_` are used to define _italic_ text. Style the names of things in italics, except input fields or buttons: + +```markdown +Here are some American things: + +- The _Spirit of St Louis_. +- The _White House_. +- The United States _Declaration of Independence_. + +Try entering them into the **American** field and clicking **Accept**. +``` + +Quotes or sections of quoted text are styled in italics and surrounded by double quotes `"`: + +```markdown +In the wise words of Winnie the Pooh _"People say nothing is impossible, but I do nothing every day."_ +``` + +**Code blocks** + +Tag code blocks with the syntax of the core they are presenting: + +````markdown + ```javascript + console.log(error); + ``` +```` + +Output from command-line actions can be displayed by adding another codeblock directly after the input codeblock.

In the Filecoin network, there are two types of actors: + +* [_Built-in actors_](actors.md#built-in-actors): Hardcoded programs, written ahead of time by network engineers that manage and orchestrate key subprocesses and subsystems in the Filecoin network. +* [_User actors_](actors.md#user-actors-smart-contracts): Code implemented by **any developer** that interacts with the Filecoin Virtual Machine (FVM). + +## Built-in actors + +Built-in actors are how the Filecoin network manages and updates _global state_. The _global state_ of the network at a given epoch can be thought of as the set of blocks agreed upon via network consensus in that epoch. This global state is represented as a _state tree_, which maps an actor to an _actor state_. An _actor state_ describes the current conditions for an individual actor, such as its FIL balance and its nonce. In Filecoin, actors trigger a _state transition_ by sending a _message_. Each block in the chain can be thought of as a **proposed** global state, where the block selected by network consensus sets the **new** global state. Each block contains a series of messages, and a checkpoint of the current global state after the application of those messages. The Filecoin Virtual Machine (FVM) is the Filecoin network component that is in charge of execution of all actor code. + +A basic example of how actors are used in Filecoin is the process by which storage providers prove storage and are subsequently rewarded. The process is as follows: + +1. The [`StorageMinerActor`](actors.md#storagemineractor) processes proof of storage from a storage provider. +2. The storage provider is awarded storage power based on whether the proof is valid or not. +3. The [`StoragePowerActor`](actors.md#storagepoweractor) accounts for the storage power. +4. During block validation, the [`StoragePowerActor`](actors.md#storagepoweractor)’s state, which includes information on storage power allocated to each storage provider, is read. +5. Using the state information, the consensus mechanism randomly awards blocks to the storage providers with the most power, and the [`RewardActor`](actors.md#rewardactor) sends FIL to storage providers. + +### Blocks + +Each block in the Filecoin chain contains: + +* Inline data such as current block height. +* A pointer to the current state tree. +* A pointer to the set of messages that, when applied to the network, generated the current state tree. + +### State tree + +A [Merkle Directed Acyclic Graph (Merkle DAG)](../../reference/general/glossary.md#merkle-directed-acyclic-graph) is used to map the state tree and the set of messages.

Messages sent to an actor contain information on which method(s) to call, and the input parameters for those methods. Additionally, actor code interacts with a _runtime_ object, which contains information on the general state of network, such as the current epoch, and cryptographic signatures and proof validations. Like smart contracts in other blockchains, actors must pay a _gas fee_, which is some predetermined amount of FIL to offset the cost (network resources used, etc.) of a transaction. Every actor has a Filecoin balance attributed to it, a state pointer, a code which tells the system what type of actor it is, and a nonce, which tracks the number of messages sent by this actor + +### Types of built-in actors + +The 11 different types of built-in actors are as follows: + +* [CronActor](actors.md#cronactor) +* [InitActor](actors.md#initactor) +* [AccountActor](actors.md#accountactor) +* [RewardActor](actors.md#rewardactor) +* [StorageMarketActor](actors.md#storagemarketactor) +* [StorageMinerActor](actors.md#storagemineractor) +* [MultisigActor](actors.md#multisigactor) +* [PaymentChannelActor](actors.md#paymentchannelactor) +* [StoragePowerActor](actors.md#storagepoweractor) +* [VerifiedRegistryActor](actors.md#verifiedregistryactor) +* [SystemActor](actors.md#systemactor) + +#### CronActor + +The `CronActor` sends messages to the `StoragePowerActor` and `StorageMarketActor` at the end of each epoch. The messages sent by `CronActor` indicate to StoragePowerActor and StorageMarketActor how they should maintain internal state and process deferred events. This system actor is instantiated in the genesis block, and interacts directly with the FVM. + +#### InitActor + +The `InitActor` can initialize new actors on the Filecoin network. This system actor is instantiated in the genesis block, and maintains a table resolving a public key and temporary actor addresses to their canonical ID addresses. The `InitActor` interacts directly with the FVM. + +#### AccountActor + +The `AccountActor` is responsible for user accounts. Account actors are not created by the `InitActor`, but by sending a message to a public-key style address. The account actor updates the state tree with new actor address, and interacts directly with the FVM. + +#### RewardActor + +The `RewardActor` manages unminted Filecoin tokens, and distributes rewards directly to miner actors, where they are locked for vesting. The reward value used for the current epoch is updated at the end of an epoch. The `RewardActor` interacts directly with the FVM. + +#### StorageMarketActor + +The `StorageMarketActor` is responsible for processing and managing on-chain deals. This is also the entry point of all storage deals and data into the system. This actor keeps track of storage deals, and the of locked balances of both the client storing data and the storage provider. When a deal is posted on chain through the `StorageMarketActor`, the actor will first check if both transacting parties have sufficient balances locked up and include the deal on chain. Additionally, the `StorageMarketActor` holds _Storage Deal Collateral_ provided by the storage provider to collateralize deals. This collateral is returned to the storage provider when all deals in the sector successfully conclude. This actor does not interact directly with the FVM. + +#### StorageMinerActor + +The `StorageMinerActor` is created by the `StoragePowerActor`, and is responsible for storage mining operations and the collection of mining proofs. This actor is a key part of the Filecoin storage mining subsystem, which ensures a storage miner can effectively commit storage to the Filecoin, handles the following: + +* Committing new storage +* Continuously proving storage +* Declaring storage faults +* Recovering from storage faults + +This actor does not interact directly with the FVM. + +#### MultisigActor + +The `MultisigActor` is responsible for dealing with operations involving the Filecoin wallet, and represents a group of transaction signers, with a maximum of 256. Signers may be external users or the `MultisigActor` itself. This actor does not interact directly with the FVM. + +#### PaymentChannelActor + +The `PaymentChannelActor` creates and manages _payment channels_, a mechanism for off-chain microtransactions for Filecoin dApps to be reconciled on-chain at a later time with less overhead than a standard on-chain transaction, and no gas costs. Payment channels are uni-directional and can be funded by adding to their balance. To create a payment channel and deposit fund, a user calls the `PaymentChannelActor`. This actor does not interact directly with the FVM. + +#### StoragePowerActor + +The `StoragePowerActor` is responsible for keeping track of the storage power allocated to each storage miner, and has the ability to create a `StorageMinerActor`. This actor does not interact directly with the FVM. + +#### VerifiedRegistryActor + +The `VerifiedRegistryActor` is responsible for managing Filecoin Plus (Fil+) clients. This actor can add a verified client to the Fil+ program, remove and reclaim expired DataCap allocations and manage claims. This actor does not interact directly with the FVM. + +#### SystemActor + +For more information on `SystemActor`, see the [source code](https://github.com/filecoin-project/specs-actors/blob/master/actors/builtin/system/system\_actor.go). + +## User actors (smart contracts) + +A _user actor_ is code defined by **any developer** that can interact FVM, otherwise known as a _smart contract_. + +A _smart contract_ is a small, self-executing blocks of custom code that runs on other blockchains, like Ethereum. In the Filecoin network, the term is a synonym for [_user actor_](actors.md#user-actors-smart-contracts).

In future updates, any language that compiles to WASM will be supported. With user actors, users can create and enforce custom rules for storing and accessing data on the network. The FVM is responsible for actors and ensuring that they are executed correctly and securely. diff --git a/basics/the-blockchain/addresses.md b/basics/the-blockchain/addresses.md new file mode 100644 index 000000000..ab128ff8a --- /dev/null +++ b/basics/the-blockchain/addresses.md @@ -0,0 +1,71 @@ +--- +description: >- + A Filecoin address is an identifier that refers to an actor in the Filecoin + state.

An _ID address_ is an actor’s ID prefixed with the network identifier and the address type. + +Actor ID addresses are not _robust_, in the sense that they do depend on chain state, and are defined on-chain by the `InitActor`. Additionally, actor IDs can change for a brief time after creation if the same ID is assigned to different actors on different forks. Actor ID addresses are similar to monotonically increasing numeric primary keys in a relational database. So, when a chain reorganization occurs (similar to a rollback in a SQL database), you can refer to the same ID for different rows. The expected consensus algorithm will resolve the conflict. Once the state that defines a new ID reaches finality, no changes can occur, and the ID is bound to that actor forever. + +For example, the mainnet burn account ID address, `f099`, is structured as follows: + +```plaintext + Address type + | +f 0 9 9 +| | +| Actor ID +| +Network identifier +``` + +ID addresses are often referred to by their shorthand `f0`. + +## Public keys + +Actors managed directly by users, like accounts, are derived from a public-private key pair. If you have access to a private key, you can sign messages sent from that actor. The public key is used to derive an address for the actor. Public key addresses are referred to as _robust addresses_ as they do not depend on the Filecoin chain state. + +Public key addresses allow devices, like hardware wallets, to derive a valid Filecoin address for your account using just the public key. The device doesn’t need to ask a remote node what your ID address is. Public key addresses provide a concise, safe, human-readable way to reference actors before the chain state is final.

This implements the same design as ETH2, but contrasts with Zcash, which has signatures on `G1` and public keys on `G2`.

In Ethereum, for example, the blocktime is approximately 15 seconds on average, meaning that a new block is added to the Ethereum blockchain roughly every 15 seconds. + +In the Filecoin network, storage providers compete to produce blocks by providing storage capacity and participating in the consensus protocol. The block time determines how frequently new blocks are added to the blockchain, which impacts the overall speed and responsiveness of the network. + +Filecoin has a block time of 30 seconds, and this duration was chosen for two main reasons: + +* **Hardware requirements**: If the block time were faster while maintaining the same gas limit or the number of messages per block, it would lead to increased hardware requirements.

EC is a probabilistic Byzantine fault-tolerant consensus protocol that runs a leader election among a set of storage providers to submit a block every epoch. Like proof-of-stake, Filecoin uses proof-of-storage for the leader election, meaning the likelihood of being elected depends on how much provable storage power a miner contributes to the network. The storage power of the network is stored in the storage power table and managed by the Storage Power Actor. + +At a high level, the consensus process relies on [Drand](https://drand.love) to provide distributed and verifiable randomness to keep leader election secret, fair and verifiable. All the election participants and their power are drawn from the Power Table, which is calculated and maintained over time by the Storage Power Consensus subsystem. Eventually, EC takes all valid blocks produced in this epoch and uses a weighting function to select the chain with the highest weight to add blocks. + +### Block production process + +The process of producing a block for each epoch can be briefly described as follows: + +* Elect leaders from eligible miners. +* Miners need to check if they are elected. +* An elected miner gets the randomness value to generate WinningPoSt. +* If all above is successful, miners build and propagate a block. +* Verify whether a miner won the block and verify the leader election. +* Eventually, select the heaviest chain to add blocks. + +### Finality + +EC enforces a version of soft finality whereby all miners at round `N` will reject all blocks that fork off before round `N - F`. `F` is set to `900`. This is important to enforce finality at no cost to chain availability and functionality. + +## Proofs + +As a decentralized storage network, Filecoin is built on the proof-of-storage in which miners contribute their vacant storage space to the network to store data and then provide proofs for the client to verify if their data has been stored throughout a period. + +### Proof of replication + +Using proof-of-replication (PoRep), storage providers prove that they have created a unique copy of the client’s data and stored it on behalf of the network. + +### Proof of spacetime + +Storage providers also need to continuously prove that they store clients’ data for the whole lifetime of the storage deal. There are two types of challenges as part of the proof-of-spacetime (PoSt) process: + +* Winning PoSt guarantees that the storage provider maintains a copy of data at a specific time. +* Window PoSt is used as proof that a copy of the data has been continuously maintained over time. + +### Slashing + +If storage providers fail to provide reliable uptime or act maliciously against the network, they will be penalized by slashing.

The goal with the compute-over-data protocols is generally to perform computation over IPLD, which is the data layer used by content-addressed systems like Filecoin. There are working groups working on different types of computing on Filecoin data, such as large-scale parallel compute (e.g., Bacalhau) and cryptographically verifiable compute (e.g. [Lurk](https://filecoin.io/blog/posts/introducing-lurk-a-programming-language-for-recursive-zk-snarks/)), etc. + +For example, [Bacalhau](https://www.bacalhau.org/) is a platform for public, transparent, and optionally verifiable distributed computation.

By supporting compute-over-data on the Filecoin network, we enable a new paradigm of computing on the data where the data exists rather than moving the data to external compute nodes. + +## Filecoin virtual machine + +The Filecoin virtual machine (FVM) is a runtime environment for smart contracts on the Filecoin network. Smart contracts enable users to run any bounded computation, including those that create and enforce rules for storing and accessing data on the network. The FVM is responsible for executing these smart contracts and ensuring they are executed correctly and securely. + +FVM is designed to support native Filecoin actors written in languages that compile to WASM, as well as smart contracts written for foreign runtimes, including Solidity contracts for Ethereum Virtual Machine (EVM), Secure EcmaScript (SES), and eBPF. The [reference FVM](https://github.com/filecoin-project/ref-fvm) and SDK are written in Rust. + +According to the FVM roadmap, we initially support smart contracts written in Solidity and eventually support any language that compiles to WASM. + +The FVM enables compute-over-states on the Filecoin network and allows developers to build endless new use cases on top of Filecoin. Some example use cases are: + +### Data organizations + +FVM can create a new kind of organization – one built around datasets of various kinds. + +#### Data DAO and tokenized datasets + +The FVM enables the creation and management of data-based decentralized and autonomous organizations – data DAOs. The FVM allows a group of individuals, or organizations, to curate and preserve data collection. Data DAOs can govern and monetize data access and pool the returns into a shared treasury to fund the collections preservation and long-term growth. One could even exchange those data tokens between peers and request computation services on that data, such as validation, joins, analysis, feature detection, and extraction, moving into machine learning. + +#### Perpetual storage + +FVM allows users to store once and have repair and replication bots manage the repetitive storage deal creation tasks so that data can be stored perpetually. Using a smart contract, users can provision a wallet with FIL, and storage providers can use that to fund data storage permanently. Repair bots can monitor the storage deals and replicate the data with other storage providers when necessary. This process gives users long-term storage permanence. + +### Financial services for miners + +FVM can provide a variety of financial services for storage providers. The needs of these SPs are unique to the Filecoin ecosystem. + +#### Lending and staking protocols + +Users can lend out Filecoin to storage providers to use it as storage collateral and receive interest in return. These loans can be undercollateralized based on the on-chain storage history of past storage provider performance. Community members can use this history to generate reputation scores, enabling everyone to identify good borrowers. On top of that, loans can be automatically paid back to investors by using a multisig as the storage provider’s owner address, including lenders and a third party, to help negotiate payback. New FVM-enabled smart contracts give every FIL token holder access to new yield opportunities on their holdings while also benefiting the whole Filecoin economy by allowing entry ramps for providing storage on the network. + +#### Insurance + +SPs need to have financial products that help protect them from the risk they are undertaking in creating more storage solutions. Certain characteristics such as payment history, length of operation, and availability can be used to craft insurance policies just as they can be used to underwrite loans to SPs. This can protect them from the financial consequences of active faulting or token price drops. + +### Core chain infrastructure + +We expect that FVM will gain feature parity with other chains that persist. This is required for any EVM chain to operate but is not necessarily tied to storage primitives. + +#### Decentralized exchanges + +Users on FVM need to be able to exchange FIL for other tokens issued on-chain. This may be a decentralized exchange such as a fork of Uniswap or Sushi or involve building a decentralized order book similar to Serum on Solana. + +#### Token bridges + +While not immediately on the roadmap, bridges are needed from EVM chains, Move chains, and Cosmos chains to bring wrapped tokens from other ecosystems into the fold. With the current launch, we are more focused internally since the value proposition of Filecoin is unique enough that it does not need to bootstrap TVL from other chains. However, in the long run, we expect FVM to be part of a broader family of blockchains. + +Besides these, there are a lot more use cases that the FVM could enable, such as data access control ([Medusa](https://cryptonet.org/projects/project-medusa-scalable-threshold-network-on-chain)), retrieval and trustless reputation systems, replication workers, storage bounties, and L2 networks.

It will allow developers to port any existing EVM-based smart contracts straight onto the FVM and make them work out of the box. FEVM emulates EVM bytecode at the low level, supporting contracts written in Solidity, Vyper, and Yul. The EVM foreign runtime is based on preexisting OSS libraries, including [SputnikVM](https://github.com/rust-blockchain/evm) and Revm. You can find out more details in the [EVM <> FVM mapping specification](https://github.com/filecoin-project/fvm-project/blob/main/04-evm-mapping.md). + +Because Filecoin nodes offer the Ethereum JSON-RPC API support, FEVM is also completely compatible with any EVM development tools, such as Hardhat, Brownie, and MetaMask. Most smart contracts ported to Filecoin shouldn’t require changes or auditing. For example, new ERC-20 tokens can be launched on the Filecoin network or bridged directly to token pools on other chains. + +Developers can deploy actors on either the FEVM or native FVM; which one should you choose? The decision can be summed up as such: if you want better performance, write actors that are compiled to WASM and deployed to native FVM. If you are familiar with Solidity and want access to the EVM ecosystem of tools, but don’t mind slightly less performance, deploy to the FEVM. + +To sum it up, the FEVM allows current Web3 developers to quickly start writing actors on the Filecoin blockchain while using all of the tools, software packages, and languages they are used to while having access to Filecoin storage deals as a native. + +The difference between FEVM and EVM contracts is that contracts deployed on FEVM can interact with built-in actors to interact with Filecoin-specific actors, such as miner actors, as mentioned in the built-in actor section. This allows developers to build Filecoin-native decentralized applications for the new use cases mentioned above. Smart contracts deployed to the Ethereum blockchain have no direct access to the Filecoin network or Filecoin-specific actors. + +To allow Solidity smart contracts on FEVM to seamlessly call methods on Filecoin built-in actors and access Filecoin-specific syscalls idiomatically, a Filecoin-Solidity API library has been developed, you can use it for building your use cases, such as interacting with storage deals. + +If you build on FEVM, you might find some of the [example contracts here](https://github.com/lotus-web3/client-contract) helpful. diff --git a/basics/what-is-filecoin/retrieval-market.md b/basics/what-is-filecoin/retrieval-market.md new file mode 100644 index 000000000..6f53f7a7f --- /dev/null +++ b/basics/what-is-filecoin/retrieval-market.md @@ -0,0 +1,22 @@ +--- +description: >- + The retrieval market refers to negotiating retrieval deals for a provider to + serve stored data to a client.

Generally, the network speed between client and storage provider is the limiting factor in transfer rate. +3. _Deal shows up on-chain_: Once the data is received, the storage provider verifies that it matches the deal parameters. Then, the provider publishes the deal on the chain. +4. _Sector sealing_: Once the deal shows up on-chain, the storage provider must still generate Proof-of-Replication and seal the sector. This process is currently estimated to take roughly 1.5 hours for a 32 GB sector on a machine that meets the minimum hardware requirements for storage providers. + +For the majority of clients, the most important metric is the time from deal acceptance to deal appearance on-chain. This metric is the sum of the time required to complete steps (1) through (3), described above. Based on current high-level benchmarks, these steps are estimated to take roughly 5-10 minutes for a 1 MiB file. + +## Data retrieval + +There are two methods by which one can directly retrieve data from the Filecoin network: + +* **Fast retrieval**: By default, some Filecoin clients, like lotus, enable storage providers to store an unsealed copy of the stored data in addition to a sealed copy. The sealed copy is necessary for the ongoing storage proofs that a storage provider must submit, while the unsealed copy can be used for quicker retrievals of the data from the storage provider. While this is a valuable feature, there is no guarantee that all storage providers are storing extra unsealed copies of the stored data, as this is not a verifiable part of the protocol. In lotus, this feature is called _fast-retrieval_. +* **Retrieval after unsealing**: Because of the Filecoin protocol’s design, storage providers are essentially cryptographically guaranteed to store client data in its sealed format. Therefore, if the storage provider doesn’t have an unsealed copy of the data stored, they will have to unseal the sealed data first (i.e., decoding the encoded data) and then serve it back up to the requester (i.e., the retrieval client). + +In both methods, the data retrieval process after a retrieval deal is accepted includes: + +1. **Funding the payment channel for retrieval**: Similar to the storage deal payment channel funding above, except for data retrieval. The timing estimates for payment channel creation and funding are roughly the same as noted above. +2. **Unsealing (if needed)**: The storage provider unseals (decodes) the data so that the requester can read it. Sealing and unsealing are symmetric processes, which means they take roughly the same amount of time in either direction. Thus, the unsealing step is estimated to take around as long as the sealing step listed above, or around \~3 hours for a 32 GiB sector on a machine running minimum hardware requirements. +3. **Data transfer**: The storage provider begins transferring the data back to the data requester. This is also transferred back at a rate similar to the original data transfer rate, which depends on several factors. + +Because of the various steps involved in the data retrieval process, Filecoin storage currently meets similar performance bars as traditional _warm_ or _cold_ storage. To get performance that is similar to other hot storage solutions, most users utilize Filecoin with a caching layer such as IPFS. These hybrid and multi-tiered storage solutions use IPFS for hot storage and Filecoin for affordable, frequent, and versioned backups. Some example hybrid storage products include [Powergate](https://blog.textile.io/filecoin-developer-tools-concepts/) and [Textile Buckets](https://docs.textile.io/buckets/). diff --git a/networks/mainnet/rpcs.md b/networks/mainnet/rpcs.md new file mode 100644 index 000000000..66bb58f6d --- /dev/null +++ b/networks/mainnet/rpcs.md @@ -0,0 +1,48 @@ +--- +description: Public RPC endpoints are available for the Filecoin mainnet. +--- + +# RPCs + +{% hint style="info" %} +[Chainlist](https://chainlist.org/chain/314159) contains a dynamically updated list of available RPCs along with stats like current block-height and latency.

The _global state_ of the network at a given epoch can be thought of as the set of blocks agreed upon via network consensus in that epoch. This global state is represented as a _state tree_, which maps an actor to an _actor state_. An _actor state_ describes the current conditions for an individual actor, such as its FIL balance and its nonce. In Filecoin, actors trigger a _state transition_ by sending a _message_. Each block in the chain can be thought of as a **proposed** global state, where the block selected by network consensus sets the **new** global state. Each block contains a series of messages, and a checkpoint of the current global state after the application of those messages. The Filecoin Virtual Machine (FVM) is the Filecoin network component that is in charge of execution of all actor code. + +A basic example of how built-in actors are used in Filecoin is the process by which storage providers prove storage and are subsequently rewarded. The process is as follows: + +1. The [`StorageMinerActor`](https://docs.filecoin.io/reference/built-in-actors/overview/#storagemineractor) processes proof of storage from a storage provider. +2. The storage provider is awarded storage power based on whether the proof is valid or not. +3. The [`StoragePowerActor`](https://docs.filecoin.io/reference/built-in-actors/overview/#storagepoweractor) accounts for the storage power. +4. During block validation, the `StoragePowerActor`’s state, which includes information on storage power allocated to each storage provider, is read. +5. Using the state information, the consensus mechanism randomly awards blocks to the storage providers with the most power, and the [`RewardActor`](https://docs.filecoin.io/reference/built-in-actors/overview/#rewardactor) sends FIL to storage providers. + +## Blocks + +Each block in the Filecoin chain contains: + +* Inline data such as current block height. +* A pointer (CID) to the current state tree. +* A pointer (CID) to the set of messages that, when applied to the network, generated the current state tree. + +## State tree + +A Merkle Directed Acyclic Graph (Merkle DAG) is used map the state tree. and the set of messages.

Messages sent to an actor contain information on which method(s) to call, and the input parameters for those methods. Additionally, actor code interacts with a _runtime_ object, which contains information on the general state of network, such as the current epoch, and cryptographic signatures and proof validations. Like smart contracts in other blockchains, actors must pay a _gas fee_, which is some predetermined amount of FIL to offset the cost (network resources used, etc.) of a transaction. Every actor has a Filecoin balance attributed to it, a state pointer, a code which tells the system what type of actor it is, and a nonce, which tracks the number of messages sent by this actor + +## Types of built-in actors + +The 11 different types of built-in actors are as follows: + +* [CronActor](https://docs.filecoin.io/reference/built-in-actors/overview/#cronactor) +* [InitActor](https://docs.filecoin.io/reference/built-in-actors/overview/#initactor) +* [AccountActor](https://docs.filecoin.io/reference/built-in-actors/overview/#accountactor) +* [RewardActor](https://docs.filecoin.io/reference/built-in-actors/overview/#rewardactor) +* [StorageMarketActor](https://docs.filecoin.io/reference/built-in-actors/overview/#storagemarketactor) +* [StorageMinerActor](https://docs.filecoin.io/reference/built-in-actors/overview/#storagemineractor) +* [MultisigActor](https://docs.filecoin.io/reference/built-in-actors/overview/#multisigactor) +* [PaymentChannelActor](https://docs.filecoin.io/reference/built-in-actors/overview/#paymentchannelactor) +* [StoragePowerActor](https://docs.filecoin.io/reference/built-in-actors/overview/#storagepoweractor) +* [VerifiedRegistryActor](https://docs.filecoin.io/reference/built-in-actors/overview/#verifiedregistryactor) +* [SystemActor](https://docs.filecoin.io/reference/built-in-actors/overview/#systemactor) + +### CronActor + +The `CronActor` sends messages to the `StoragePowerActor` and `StorageMarketActor` at the end of each epoch. The messages sent by `CronActor` indicate to StoragePowerActor and StorageMarketActor how they should maintain internal state and process deferred events. This system actor is instantiated in the genesis block, and interacts directly with the FVM. + +### InitActor + +The `InitActor` can initialize new actors on the Filecoin network. This system actor is instantiated in the genesis block, and maintains a table resolving a public key and temporary actor addresses to their canonical ID addresses. The `InitActor` interacts directly with the FVM. + +### AccountActor + +The `AccountActor` is responsible for user accounts. Account actors are not created by the `InitActor`, but by sending a message to a public-key style address. The account actor updates the state tree with new actor address, and interacts directly with the FVM. + +### RewardActor + +The `RewardActor` manages unminted Filecoin tokens, and distributes rewards directly to miner actors, where they are locked for vesting. The reward value used for the current epoch is updated at the end of an epoch. The `RewardActor` interacts directly with the FVM. + +### StorageMarketActor + +The `StorageMarketActor` is responsible for processing and managing on-chain deals. This is also the entry point of all storage deals and data into the system. This actor keeps track of storage deals, and the of locked balances of both the client storing data and the storage provider. When a deal is posted on chain through the `StorageMarketActor`, the actor will first check if both transacting parties have sufficient balances locked up and include the deal on chain. Additionally, the `StorageMarketActor` holds _Storage Deal Collateral_ provided by the storage provider to collateralize deals. This collateral is returned to the storage provider when all deals in the sector successfully conclude. This actor does not interact directly with the FVM. + +### StorageMinerActor + +The `StorageMinerActor` is created by the `StoragePowerActor`, and is responsible for storage mining operations and the collection of mining proofs. This actor is a key part of the Filecoin storage mining subsystem, which ensures a storage miner can effectively commit storage to the Filecoin, handles the following: + +* Committing new storage +* Continuously proving storage +* Declaring storage faults +* Recovering from storage faults + +This actor does not interact directly with the FVM. + +### MultisigActor + +The `MultisigActor` is responsible for dealing with operations involving the Filecoin wallet, and represents a group of transaction signers, with a maximum of 256. Signers may be external users or the `MultisigActor` itself. This actor does not interact directly with the FVM. + +### PaymentChannelActor + +The `PaymentChannelActor` creates and manages _payment channels_, a mechanism for off-chain microtransactions for Filecoin dApps to be reconciled on-chain at a later time with less overhead than a standard on-chain transaction, and no gas costs. Payment channels are uni-directional and can be funded by adding to their balance. To create a payment channel and deposit fund, a user calls the `PaymentChannelActor`. This actor does not interact directly with the FVM. + +### StoragePowerActor + +The `StoragePowerActor` is responsible for keeping track of the storage power allocated to each storage miner, and has the ability to create a `StorageMinerActor`. This actor does not interact directly with the FVM. + +### VerifiedRegistryActor + +The `VerifiedRegistryActor` is responsible for managing Filecoin Plus (Fil+) clients. This actor can add a verified client to the Fil+ program, remove and reclaim expired DataCap allocations and manage claims. This actor does not interact directly with the FVM. + +### SystemActor + +For more information on `SystemActor`, see the [source code](https://github.com/filecoin-project/specs-actors/blob/master/actors/builtin/system/system\_actor.go). + +## Access and invoke built-in actors + +Developers can access and invoke built-in actors the _Protocol API_ or the Zondax _filecoin.solidity_ API + +The Filecoin Solidity project is [currently in beta](https://docs.zondax.ch/fevm/filecoin-solidity#disclaimer-%EF%B8%8F%EF%B8%8F). + +* _Protocol API_, maintained by [Protocol Labs](https://protocol.ai/), … +* _Filecoin.solidity_, maintained by [Zondax](https://docs.zondax.ch/), is a set of libraries that allows Solidity smart contracts to seamlessly call built-in actors methods. **Not all built-in actors and methods are supported** - for a complete list, see the [actors and methods supported](https://docs.zondax.ch/fevm/filecoin-solidity/api/#actors-and-methods-supported).

Time in the Filecoin network is dissected into [epochs](https://spec.filecoin.io/#section-glossary.epoch) set to 30 seconds. A new set of blocks is produced for every epoch for a [tipset](https://spec.filecoin.io/#section-glossary.tipset). The hard finality of the Filecoin network is 900 epochs. + +## Accounts and wallets + +Filecoin uses an account-based model. There are 4 types of account prefixes: + +* `f0` for ID address +* `f1` for Secp256k1 wallets +* `f2`for [actor](https://spec.filecoin.io/#section-glossary.actor) accounts +* `f3` for BLS wallets + +`f1`, `f2`, and `f3` prefixed addresses are called account addresses. An account address is activated when it first receives a transaction. `f0` prefixed addresses are mapped to each active account address. + +**Testnet addresses** Within a testnet, the address prefix is `t`. So ID addresses become `t0`, Secp256k1 wallets become `t1`, etc. + +## Signatures + +Filecoin currently uses two types of signatures: + +* ECDSA signatures over the Secp256k1 elliptic curve +* BLS signatures over the BLS12-381 group of curves. + +Details and reference implementations can be found [in the Filecoin specification](https://spec.filecoin.io/#section-algorithms.crypto.signatures.signature-types). + +## Messages + +There are two message types: + +* [Signed messages](https://github.com/filecoin-project/lotus/blob/9deda06ec632da3f7a035cc63b9408de72c96f79/chain/types/signedmessage.go#L44) +* [Unsigned messages](https://github.com/filecoin-project/lotus/blob/9deda06ec632da3f7a035cc63b9408de72c96f79/chain/types/message.go#L28). + +Messages are fully irreversible at 900 epochs. Waiting 200 epochs for message confirmation is acceptable. + +There are multiple gas fees associated with each message. Refer to the [practical guide to gas section of this blog post](https://filecoin.io/blog/filecoin-features-gas-fees/) for details. + +An `ExitCode` of `0` in the message receipt indicates that the message was sent successfully. + +### Mempool + +When a user sends a transaction to the network, it gets placed into the mempool queue. If a transaction doesn’t have enough gas, it stays in the mempool and doesn’t go anywhere. To new users, it looks like this transaction is lost forever. However, users can update the transaction with an updated `GasLimit`, `GasFeeCap`, and/or `GasPremium`. As long as you don’t change anything else in the transaction (`nonse`, `to`, `from`, `value`), then the transaction that is sat in the mempool will get updated with the new gas allowance. + +**Expiration** + +There is no limit for how long a message can spend in the mempool. However, the mempool does get _cleaned_ when there are too many messages in it, starting with the messages with the least gas. + +### Automatic gas values + +When `GasFeeCap`, `GasPremium` and `MaxFee` are set to `0`, Lotus will do the gas estimation for the message with 25% overestimation for the gas limit based on the current network condition. + +Some JavaScript libraries attempt to estimate the gas fees before sending the transaction to the Filecoin network. However, they sometimes underestimate, leading to transactions getting stuck in the mempool. If you are noticing your transactions getting stuck in the mempool after sending them to the network using a JavaScript library, try `GasFeeCap`, `GasPremium`, and `MaxFee` to `0`. + +## Integration + +You can interact with the network by using Lotus CLI or using the [JSON-RPC APIs](https://lotus.filecoin.io/reference/basics/overview/). Follow the [API tokens guide](https://lotus.filecoin.io/docs/developers/api-access/) to set up API tokens on your node and grant necessary permissions.

This value, a public key, is paired with a corresponding private key. The mathematical relationship between the two keys is such that access to the private key allows the creation of a signature that can be verified with the public key. Filecoin specifically employs the Boneh–Lynn–Shacham (BLS) signature scheme for this purpose. + +## Block + +In a blockchain, a _block_ is the fundamental unit of record. Each block is cryptographically linked to one or more previous blocks. Blocks typically contain [messages](https://docs.filecoin.io/reference/general/glossary/#message) relating changes to some state (for example, financial records) tracked by the blockchain. + +## Blockchain + +Fundamentally, a _blockchain_ is a system of record in which new records, or [blocks](https://docs.filecoin.io/reference/general/glossary/#block) are cryptographically linked to preceding records. This construction is a foundational component of secure, verifiable, and distributed transaction ledgers. + +## Block height + +The _height_ of a [block](https://docs.filecoin.io/reference/general/glossary/#block) corresponds to the number of [epochs](https://docs.filecoin.io/reference/general/glossary/#epoch) elapsed before the block was added to the blockchain. The height of the Filecoin [blockchain](https://docs.filecoin.io/reference/general/glossary/#blockchain) is defined to be the maximum height of any block in the blockchain. + +## Capacity commitment + +If a storage provider doesn’t find any available deal proposals appealing, they can alternatively make a _capacity commitment_, filling a [sector](https://docs.filecoin.io/reference/general/glossary/#sector) with arbitrary data, rather than with client data. Maintaining this sector allows the storage provider to provably demonstrate that they are reserving space on behalf of the network. + +## CommP + +The commitment phase of the Proof-of-Replication (PoRep) process. PoRep is a mechanism used to verify that a storage provider is storing data on behalf of a client by requiring the provider to prove that they have replicated the client’s data to their storage space. + +## Content IDentifier (CID) + +A self-describing format for referencing data in distributed information systems by it’s _contents_, rather than its _location_ using cryptographic hashing and self-describing formats. It is a core component of IPFS and IPLD, which are in turn components of Filecoin. + +## Collateral + +In order to enter into a [storage deal](https://docs.filecoin.io/reference/general/glossary/#deal), a [storage provider](https://docs.filecoin.io/reference/general/glossary/#storage-provider) is required to provide [FIL](https://docs.filecoin.io/reference/general/glossary/#fil) as _collateral_, to be paid out as compensation to a client in the event that the provider fails to uphold their storage commitment. + +## Deal + +Two participants in the Filecoin network can enter into a _deal_ in which one party contracts the services of the other. The Filecoin specification currently details _storage deals_ (in which one party agrees to store data for the other for a specified length of time) and _retrieval deals_ (in which one party agrees to transmit specified data to the other). + +## Election + +Every [epoch](https://docs.filecoin.io/reference/general/glossary/#epoch), a small subset of Filecoin [storage providers](https://docs.filecoin.io/reference/general/glossary/#storage-provider) are _elected_ to mine a new [block](https://docs.filecoin.io/reference/general/glossary/#block) for the Filecoin blockchain. A provider’s probability of being elected is roughly proportional to the share of the Filecoin network’s total storage capacity that they contribute. + +## Epoch + +Time in the Filecoin blockchain is discretized into _epochs_ that are currently thirty seconds in length. Every epoch, a subset of storage providers are elected to each add a new block to the Filecoin blockchain via [Winning Proof-of-Spacetime](https://docs.filecoin.io/reference/general/glossary/#winning-proof-of-spacetime-winningpost). + +## FIL + +_FIL_ is the name of the Filecoin unit of currency; it is alternatively denoted by the Unicode symbol for an integral with a double stroke (⨎). + +## Faucet + +A _faucet_ is a service that provides free [FIL](https://docs.filecoin.io/reference/general/glossary/#fil). Typically, faucets are run for the benefit of new users in a network, providing them with the necessary seed capital to begin making transactions. + +## Fault + +When a [storage provider](https://docs.filecoin.io/reference/general/glossary/#storage-provider) fails to complete [Window Proof-of-Spacetime](https://docs.filecoin.io/reference/general/glossary/#window-proof-of-spacetime-windowpost) for a given sector, the Filecoin network registers a _fault_ for that sector, and the provider is [_slashed_](https://docs.filecoin.io/reference/general/glossary/#slash). If a storage provider does not resolve the fault quickly, the network assumes they have abandoned their commitment. + +## Filecoin + +The term _Filecoin_ is used generically to refer to the Filecoin project, protocol, and network. + +## Finality + +Finality refers to the immutability of messages and state recorded to the Filecoin blockchain. As new blocks are added to the blockchain, it becomes more and more difficult for older blocks to be altered, until they become effectively impossible to modify. The _finality period_ is the amount of time that must elapse before a block is considered completely immutable. In the current [mainnet](https://docs.filecoin.io/reference/general/glossary/#mainnet), this is configured as 900 [epochs](https://docs.filecoin.io/reference/general/glossary/#epoch). + +## Gas + +_Gas_ is a property of a [message](https://docs.filecoin.io/reference/general/glossary/#message), corresponding to the resources involved in including that message in a given [block](https://docs.filecoin.io/reference/general/glossary/#block). For each message included in a block, the block’s creator extracts a fee from the message’s sender; this fee is proportional to the message’s gas. + +## Mainnet + +A portmanteau of “main” and “network, _mainnet_ is a term used to refer to the predominant public-facing network of the Filecoin project and community. The mainnet embodies an expectation of widespread adoption and permanence; changes to its protocol are subject to the adoption of the network participants. + +If used as a proper noun, capitalize the term: _“I am providing on Mainnet.”_ + +## Message + +The term _message_ is used to refer to data stored as part of a [block](https://docs.filecoin.io/reference/general/glossary/#block). A block can contain several messages. + +## Merkle Directed Acyclic Graph + +Abbreviated as _Merkle DAG_. A graph data structure where nodes: + +* Have a unique identifier that is the hash of the nodes contents +* Are directionally related to other nodes +* Never form a closed loop + +Merkle DAGs are a fundamental component for the representation of relationships between content-addressed data in IPLD, which is in turn used by Filecoin. + +## Miner + +The Filecoin project uses the term _provider_ to refer to participants in the network who provide a service of value to a client. Other blockchains, like Ethereum and Bitcoin, use the term _miner_. At present, the Filecoin specification recognizes two provider types: [storage providers](https://docs.filecoin.io/reference/general/glossary/#storage-provider) and [retrieval providers](https://docs.filecoin.io/reference/general/glossary/#retrieval-provider). + +## Pledged storage + +Storage capacity that a provider has promised to reserve for the Filecoin network via [Proof-of-Replication](https://docs.filecoin.io/reference/general/glossary/#proof-of-replication-porep) is termed _pledged storage_. + +## Proof-of-Storage + +Many blockchain networks are underpinned by the notion that participants supply something of value to the blockchain - a contribution that is hard to fake, but which, if actually made, can be trivially verified. Blockchains based in this approach are often said to require “Proof-of-X”, where X is the valued contribution. The Filecoin blockchain values contributions of storage capacity; it is predicated upon a novel _Proof-of-Storage_ construction, distinguishing it from other blockchains that, as is most often the case, require a contribution of computing power. + +As a term, Proof-of-Storage refers to the design elements of the Filecoin protocol that allow one to guarantee (to some very high tolerance) that participants that claim to be contributing a given amount of storage are indeed fulfilling that pledge. In fact, Filecoin’s Proof-of-Storage construction provides for a much stronger claim, allowing one to efficiently verify that a participant is storing a _particular piece of data_, without requiring that one have a copy of the file itself. + +_Note_: “proof” here is used in an informal sense - typically, these proofs take the form of a probabilistic argument, rather than a concrete proof; that is, it might _technically_ be possible to convince other participants that one is making a contribution one is not, but the possibility is so vanishingly slight as to border on impossibility. + +## Proof-of-Replication (PoRep) + +_Proof-of-Replication_ is a procedure by which a [storage provider](https://docs.filecoin.io/reference/general/glossary/#storage-provider) can prove to the Filecoin network that they have created a unique copy of some piece of data on the network’s behalf. + +## Proof-of-Spacetime (PoSt) + +_Proof-of-Spacetime_ is a procedure by which a [storage-provider](https://docs.filecoin.io/reference/general/glossary/#storage-provider) can prove to the Filecoin network they continue to store a unique copy of some data on behalf of the network. Proof-of-Spacetime manifests in two distinct varieties in the present Filecoin specification: [Window Proof-of-Spacetime](https://docs.filecoin.io/reference/general/glossary/#window-proof-of-spacetime-windowpost) and [Winning Proof-of-Spacetime](https://docs.filecoin.io/reference/general/glossary/#winning-proof-of-spacetime-winningpost). + +## Quality-adjusted storage power + +The storage power a [storage provider](https://docs.filecoin.io/reference/general/glossary/#storage-provider) earns from a storage deal offered by a [verified client](https://docs.filecoin.io/reference/general/glossary/#verified-client) will be augmented by a multiplier. Power totals that take into account this multiplier are termed _quality adjusted_. + +## Retrieval provider + +A _retrieval provider_ is a Filecoin participant that enters retrieval [deals](https://docs.filecoin.io/reference/general/glossary/#deal) with clients, agreeing to supply a client with a particular file in exchange for [FIL](https://docs.filecoin.io/reference/general/glossary/#fil). Note that unlike [storage providers](https://docs.filecoin.io/reference/general/glossary/#storage-provider), retrieval providers are not additionally rewarded with the ability to add blocks to the Filecoin blockchain; their only reward is the fee they extract from the client. + +## Seal + +_Sealing_ is one of the fundamental building blocks of the Filecoin protocol. It is a computation-intensive process performed over a [sector](https://docs.filecoin.io/reference/general/glossary/#sector) that results in a unique representation of the sector. The properties of this new representation are essential to the [Proof-of-Replication](https://docs.filecoin.io/reference/general/glossary/#proof-of-replication-porep) and the [Proof-of-Spacetime](https://docs.filecoin.io/reference/general/glossary/#proof-of-spacetime-post) procedures. + +## Sector + +Storage providers store data on behalf of the Filecoin network in fixed-size blocks of data called _sectors_. + +## Slash + +When a [fault](https://docs.filecoin.io/reference/general/glossary/#fault) is registered for a [sector](https://docs.filecoin.io/reference/general/glossary/#sector), the Filecoin network will _slash_ the [storage provider](https://docs.filecoin.io/reference/general/glossary/#storage-provider) that is supposed to be storing the sector; that is, it will assess penalties to the provider (to be paid out of the [collateral](https://docs.filecoin.io/reference/general/glossary/#collateral) fronted by the provider) for their failure to uphold their pledge of storage. When slashing takes place, the power a provider earns for the associated sector is subtracted from the provider’s total power for the purposes of [election](https://docs.filecoin.io/reference/general/glossary/#election). + +## Storage provider + +A _storage provider_ is a Filecoin participant that stores data on behalf of the network. Storage providers are rewarded for this service through payments by clients that contract their services, as well as by periodic authorization to extend the Filecoin [blockchain](https://docs.filecoin.io/reference/general/glossary/#blockchain) with [blocks](https://docs.filecoin.io/reference/general/glossary/#block) of their own creation. When they create a block, storage providers are rewarded with newly minted [FIL](https://docs.filecoin.io/reference/general/glossary/#fil), as well as the transaction fees they can levy on other participants seeking to include [messages](https://docs.filecoin.io/reference/general/glossary/#message) in the block. + +## Storage power + +A [storage provider’s](https://docs.filecoin.io/reference/general/glossary/#storage-provider) _storage power_ is a value roughly proportional to the amount of storage capacity they make available on behalf of the network via [capacity commitments](https://docs.filecoin.io/reference/general/glossary/#capacity-commitment) or [storage deals](https://docs.filecoin.io/reference/general/glossary/#deal). Storage power is used to select storage providers for rewards in proportion to their contributions to the total network storage capacity. + +## Zero-knowledge succinct non-interactive argument of knowledge (zk-SNARK) + +An _argument of knowledge_ is a construction by which one party, called the _prover_, can convince another, the _verifier_, that the prover has access to some piece of information. There are several possible constraints on such constructions: + +* A _non-interactive_ argument of knowledge has the requirement that just a single message, sent from the prover to the verifier, should serve as a sufficient argument. +* A _zero-knowledge_ argument of knowledge has the requirement that the verifier should not need access to the knowledge the prover has access to in order to verify the prover’s claim. +* A _succinct_ argument of knowledge is one that can be “quickly” verified, and which is “small”, for appropriate definitions of both of those terms. + +A zero-knowledge, succinct non-interactive argument of knowledge (zk-SNARK) embodies all of these properties. Filecoin utilizes these constructions to enable its distributed network to efficiently verify that [storage providers](https://docs.filecoin.io/reference/general/glossary/#storage-provider) are storing files they pledged to store, without requiring the verifiers to maintain copies of these files themselves. + +## Testnet + +A portmanteau of “test” and “network, _testnet_ is a term used to refer to one of the [primary Filecoin testing networks](https://network.filecoin.io/#calibration). + +Note: if used as a proper noun, capitalize the term. For example, “I am providing on Testnet.” + +## Tipset + +A [tipset](https://filecoin.io/blog/tipsets-family-based-approach-to-consensus/) is a set of [blocks](https://docs.filecoin.io/reference/general/glossary/#block) that each have the same [height](https://docs.filecoin.io/reference/general/glossary/#block-height) and parent tipset; the Filecoin [blockchain](https://docs.filecoin.io/reference/general/glossary/#blockchain) is a chain of tipsets, rather than a chain of blocks. + +Each tipset is assigned a weight corresponding to the amount of storage the network is provided per the commitments encoded in the tipset’s blocks. The consensus protocol of the network directs nodes to build on top of the heaviest chain. + +By basing its blockchain on tipsets, Filecoin can allow multiple [storage providers](https://docs.filecoin.io/reference/general/glossary/#storage-provider) to create blocks in the same [epoch](https://docs.filecoin.io/reference/general/glossary/#epoch), increasing network throughput. By construction, this also provides network security: a node that attempts to intentionally prevent the valid blocks of a second node from making it onto the canonical chain runs up against the consensus preference for heavier chains. + +## Verified client + +To further incentivize the storage of “useful” data over simple [capacity commitments](https://docs.filecoin.io/reference/general/glossary/#capacity-commitment), [storage providers](https://docs.filecoin.io/reference/general/glossary/#storage-provider) have the additional opportunity to compete for special [deals](https://docs.filecoin.io/reference/general/glossary/#deal) offered by [verified clients](https://docs.filecoin.io/reference/general/glossary/#verified-client). Such clients are certified with respect to their intent to offer deals involving the storage of meaningful data, and the power a storage provider earns for these deals is augmented by a multiplier. + +## Window Proof-of-Spacetime (WindowPoSt) + +_Window Proof-of-Spacetime_ (WindowPoSt) is the mechanism by which the commitments made by [storage providers](https://docs.filecoin.io/reference/general/glossary/#storage-provider) are audited. It sees each 24 hour period broken down into a series of windows. Correspondingly, each storage provider’s set of pledged [sectors](https://docs.filecoin.io/reference/general/glossary/#sector) is partitioned into subsets, one subset for each window. Within a given window, each storage provider must submit a [Proof-of-Spacetime](https://docs.filecoin.io/reference/general/glossary/#proof-of-spacetime-post) for each sector in their respective subset. This requires ready access to each of the challenged sectors, and will result in a proof compressed via [zk-SNARK](https://docs.filecoin.io/reference/general/glossary/#zero-knowledge-succinct-non-interactive-argument-of-knowledge-zk-snark) being published to the Filecoin [blockchain](https://docs.filecoin.io/reference/general/glossary/#blockchain) as a [message](https://docs.filecoin.io/reference/general/glossary/#message) in a [block](https://docs.filecoin.io/reference/general/glossary/#block). In this way, every sector of [pledged storage](https://docs.filecoin.io/reference/general/glossary/#pledged-storage) is audited at least once in any 24 hour period, and a permanent, verifiable, and public record attesting to each storage provider’s continued commitment is kept. + +The Filecoin network expects constant availability of stored data. Failing to submit WindowPoSt for a sector will result in a [fault](https://docs.filecoin.io/reference/general/glossary/#fault), and the storage provider supplying the sector will be [slashed](https://docs.filecoin.io/reference/general/glossary/#slash). + +## Winning Proof-of-Spacetime (WinningPoSt) + +_Winning Proof-of-Spacetime_ (WinningPoSt) is the mechanism by which [storage providers](https://docs.filecoin.io/reference/general/glossary/#storage-provider) are rewarded for their contributions to the Filecoin network. At the beginning of each [epoch](https://docs.filecoin.io/reference/general/glossary/#epoch), a small number of storage providers are [elected](https://docs.filecoin.io/reference/general/glossary/#election) to each mine a new [block](https://docs.filecoin.io/reference/general/glossary/#block). As a requirement for doing so, each provider is tasked with submitting a compressed [Proof-of-Storage](https://docs.filecoin.io/reference/general/glossary/#proof-of-storage) for a specified [sector](https://docs.filecoin.io/reference/general/glossary/#sector). Each elected provider who successfully creates a block is granted [FIL](https://docs.filecoin.io/reference/general/glossary/#fil), as well as the opportunity to charge other Filecoin participants fees to include [messages](https://docs.filecoin.io/reference/general/glossary/#message) in the block. + +Storage providers who fail to do this in the necessary window will forfeit their opportunity to mine a block, but will not otherwise incur penalties for their failure to do so. diff --git a/reference/general/specifications.md b/reference/general/specifications.md new file mode 100644 index 000000000..98058a37d --- /dev/null +++ b/reference/general/specifications.md @@ -0,0 +1,15 @@ +--- +description: >- + This page quickly covers what the Filecoin Specification is, and how you can + access it. +--- + +# Specifications + +The Filecoin specification is the technical document that outlines the details of how the Filecoin network operates, including the rules for participating in the network, the format of the transactions that are used to manage data storage, and the algorithms and data structures that are used to store and retrieve data on the network.

Before the Filecoin virtual machine was implemented into the network, storage deals could only be created using the following workflow: + +![Offline deal-making workflow](https://docs.filecoin.io/smart-contracts/developing-contracts/client-contract-tutorial/deal-workflow\_huf733bba29f74cfe3f5265eabb149070a\_158858\_1224x0\_resize\_q75\_h2\_box\_3.webp) + +This process requires a lot of different actions to be taken by both the client and the storage provider. But with the advent of the Filecoin Virtual Machine, smart contracts can be deployed on top of the Filecoin blockchain. This allows developers to access and now create Filecoin Storage Deals within smart contracts! And thus, now developers can also create new storage deals on the Filecoin blockchain. This reduces the number of actions clients, and storage providers have to take to generate storage deals. + +### Smart contract deal creation workflow + +To create storage deals, smart contracts need a specific Solidity event called `DealProposalCreate`. Storage Providers running [Boost software](https://boost.filecoin.io/) can then listen for this event and, if the deal is acceptable to them, pick up the deal automatically. The workflow can be seen below. + +
    + +## Steps + +Let’s now run through how to create storage deals via smart contracts. + +### Setup + +First, let’s grab the kit and set up the development environment. + +1. Clone the Filecoin virtual machine deal-making kit, including all submodules: + +```sh +git clone --recurse-submodules https://github.com/filecoin-project/fvm-starter-kit-deal-making.git +``` + +2. This will copy the fvm deal-making kit into your current directory and initiate the `go-generate-car` submodule. +3. Moving into the `fvm-starter-kit-deal-making` directory and grab all the dependencies using `yarn`: + +```sh +cd fvm-starter-kit-deal-making +yarn +``` + +4. Now that all the packages are downloaded, we will need to create a `.env` file with your private key. This is so the hardhat kit knows what wallet to use for transactions. Open up the repo in your code editor of choice and find the file titled `.env.example`. Rename the file to `.env`. + +```sh +mv .env.example .envll +``` + +5. Replace the example private key with your actual private key. If you are using Metamask, follow [this tutorial to get your private key](https://support.metamask.io/hc/en-us/articles/360015289632-How-to-export-an-account-s-private-key). Remember to take precautions to never share your private key with anyone or check it into Git! The `.gitignore` of the hardhat kit is already set to ignore `.env` files. +6. Deploy the contracts with `hardhat`: + +```sh +yarn hardhat deploy +``` + +7. This should compile and deploy all the contracts, including the client contract, which is the one we will be interacting with. Copy and take note of the address of the deployed contract for later. + +### Preparing a file for storage + +Before storing a file with a storage provider, it needs to be prepared by turning it into a `.car` file, and the metadata must be recorded. To do this the Hardhat kit has a tool [which can do this for you](https://github.com/filecoin-project/fevm-hardhat-kit/tree/main/tools). However, to keep things nice and simple, we’re going to use the [FVM Data Depot website](https://data.lighthouse.storage/). This website will automatically convert files to the `.car` format, output all the necessary metadata, and act as an HTTP retrieval point for the storage providers. + +1. Go to the [FVM Data Depot website](https://data.lighthouse.storage/) and create an account. +2. Click **Upload File** and select a file you wish to upload. +3. Select the **File ID** of the file to read all the relevant metadata. Make a note of the: + + * Piece CID + * Payload CID + * Car size + * Piece size + * URL + + We’ll use this information in the next step when invoking the `MakeDealProposal` method. + +### Invoke the MakeDealProposal method + +Now that we have the `.car` file prepared in the data depot, we can invoke the MakeDealProposal method on the smart contract we deployed earlier. To do this, we will run the `make-deal-proposal` task in Hardhat. There are quite a few parameters to include in this call: + +* `contract`: the address of your deployed `ClientContract.sol` +* \`piece-cid: gathered from the previous step. +* `piece-size`: gathered from the previous step. +* `car-size`: gathered from the previous step. +* `start-epoch`: The block number you want the deal to begin on. It should be a block in the future. You can find the current block number on [FilFox Calibration](https://calibration.filfox.info/en). +* `end-epoch`: The block number you want the deal to end on. It should be a block in the future and after the `Start-Epoch`. You can find the current block number on [FilFox Calibration](https://calibration.filfox.info/en). +* `location-ref`: The location of where the storage provider can find the .car file. This is the `URL` from the previous step. + +When calling the `make-deal-proposal` task in Hardhat, your command will look something like this: + +```shell +yarn hardhat make-deal-proposal \ + --contract 0x0219eB1740C315fe5e20612D7E13AE2A883dB3f4 \ + --piece-cid baga6ea4seaqn4eomxfk3ttog7lnvlvedu7nia377w4gotw2pm746k6kq7gwe6ga \ + --piece-size 2097152 \ + --verified-deal false \ + --car-size 1439368 \ + --label baga6ea4seaqn4eomxfk3ttog7lnvlvedu7nia377w4gotw2pm746k6kq7gwe6ga \ + --start-epoch 180000 \ + --end-epoch 700000 \ + --storage-price-per-epoch 0 \ + --provider-collateral 0 \ + --client-collateral 0 \ + --extra-params-version 1 \ + --location-ref "https://bafybeidguwwno5ohjss7g4l6ygvyy3dzxxrkkgtxqkobnnxnu62aw4ipxa.ipfs.w3s.link/ipfs/bafybeidguwwno5ohjss7g4l6ygvyy3dzxxrkkgtxqkobnnxnu62aw4ipxa/baga6ea4seaqn4eomxfk3ttog7lnvlvedu7nia377w4gotw2pm746k6kq7gwe6ga.car \ + --skip-ipni-announce true \ + --remove-unsealed-copy true \ +``` + +Parameters such as the `collateral` and `price-per-epoch` are set to `0`. On mainnet, these would be determined by storage providers, but since this is on the Calibration testnet, the storage providers should pick up the jobs even with these parameters set to `0`. + +### Storage provider picks up the job + +Now if you’ve invoked the task with all the correct parameters, the method will execute on-chain and emit an event that Boost storage providers will be listening to. If the deal is well-formed and the parameters are acceptable, they will download the .car file, double-check to ensure the `piece-cid` and `piece-size` match the deal and publish your storage deal! This could take up to a day. Once the deal is published, you can find it on a [Calibration testnet block explorer](../../networks/calibration/explorers.md). The client in the deal should be the `t4` address of the smart contract we called `MakeStorageDeal` on. + +## Conclusion + +During this tutorial, we have shown the significance of making deals using smart contracts and then walked through making a storage deal using the FVM deal-making kit and web3.storage. Developers can make use of this workflow to integrate decentralized storage on Filecoin with their smart contracts and decentralized applications. diff --git a/smart-contracts/developing-contracts/filecoin.sol.md b/smart-contracts/developing-contracts/filecoin.sol.md new file mode 100644 index 000000000..45e42cc96 --- /dev/null +++ b/smart-contracts/developing-contracts/filecoin.sol.md @@ -0,0 +1,109 @@ +--- +description: >- + External Solidity libraries can help developers create their applications + quicker by offloading some of the work to already existing smart contracts. +--- + +# Filecoin.sol + +The Filecoin Solidity library allows developers to: + +* Interact with Filecoin built-in actors. +* Simplify the interaction with the Filecoin storage market, miner actors, the verified registry for FIL+ automation, and more. +* Filecoin-specific data types such as `FilAddress`, `FilActorID`, `CIDs`, storage deals, and more. +* OpenZeppelin-like utilities specific to Filecoin. +* CBOR serialization and deserialization for parameters and return data. + +In order to access exported Filecoin built-in actor methods in your smart contract, you will need to import Filecoin.sol in your Solidity project.

A message is sent from the account that would exist at that placeholder’s address. If this happens, the placeholder is automatically upgraded into an account. +2. An EVM smart contract is deployed to the address. + +## Ethereum-style account + +An Ethereum-style account is the Filecoin EVM runtime equivalent of an account with an `f1` or `f3` address, also known as native accounts. However, there are a few key differences: + +1. These accounts have `0x`-style addresses and an equivalent `f`-style address starting with `f410f`. +2. Messages from these accounts can be sent with Ethereum wallets like MetaMask by connecting the wallet to a Filecoin client. +3. These accounts can be used to transfer funds to native or Ethereum-style. +4. They can be used to call EVM smart contracts and can be used to deploy EVM smart contracts. However, they cannot be used to call native actors such as multisig or miner actors. + +## EVM smart contract + +An EVM smart contract actor hosts a single EVM smart contract.

The integer that gets assigned is the ID of that actor. An _ID address_ is an actor’s ID prefixed with the network identifier and the protocol indicator.

It provides a way to create robust addresses for actors not associated with a public key. They are generated by taking a `sha256` hash of the output of the account creation. + +Actor addresses are often referred to by their shorthand, `2`. + +## Wallet addresses + +Addresses managed directly by users, like accounts, are derived from a public-private key pair. If you have access to a private key, you can sign messages sent from that wallet address. The public key is used to derive an address for the actor. Public key addresses are referred to as _robust addresses_ as they do not depend on the Filecoin chain state. + +Public key addresses allow devices, like hardware wallets, to derive a valid Filecoin address for your account using just the public key. The device doesn’t need to ask a remote node what your ID address is. Public key addresses provide a concise, safe, human-readable way to reference actors before the chain state is final. ID addresses are a space-efficient way to identify actors in the Filecoin chain state, where every byte matters. + +Filecoin supports two types of public key addresses: + +* [secp256k1 addresses](https://en.bitcoin.it/wiki/Secp256k1) that begin with the protocol indicator as `1`. +* [BLS addresses](https://en.wikipedia.org/wiki/BLS\_digital\_signature) that begin with the protocol indicator as `3`. + +`t1iandfn6d...ddboqxbhoeva` - a testnet wallet address generated using secp256k1. `t3vxj34sbdr3...road7cbygq` - a testnet wallet address generated using BLS. + +## Delegated addresses + +Filecoin supports extensible, user-defined actor addresses through the `4` address class, introduced in [Filecoin Improvement Proposal (FIP) 0048](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0048.md). The `4` address class provides the following benefits to the network: + +* Implement foreign addressing systems in Filecoin. +* A predictable addressing scheme to support interactions with addresses that do not yet exist on-chain. +* User-defined, programmable addressing systems without extensive changes and network upgrades. + +For example, a testnet delegated address using the Ethereum Addressing System is structured as follows: + +```plaintext + Address manager actor ID + | +t 410 iandfn6d... +| | +| New actor ID +| +Network identifier +``` + +The _address manager actor ID_ is the actor ID of the address manager actor, which creates new actors and assigns a `4` address to the new actor. This leverages the extensible feature of the `f4` address class. + +The _new actor ID_ is the arbitrary actor ID chosen by that actor. + +### Restrictions + +Currently, per [FIP 0048](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0048.md), `f4` addresses may only be assigned by and in association with specific, built-in actors called _address managers_. This restriction will likely be relaxed once users are able to deploy custom WebAssembly actors. + +This address type plays an essential role in supporting the FEVM. It allows the Filecoin network to be able to recognize the foreign address and validate and execute the transactions sent and signed by the supported foreign addresses. + +The supported foreign addresses can be cast as `f4/t4` addresses, and vice-versa. But not with `f1/t1` or `f3/t3` addresses. + +### Ethereum Address Manager + +Ethereum Address Manager (EAM) is a built-in actor that manages the Ethereum address space, anchored at the `410` address namespace. It acts like an EVM smart contract factory, offering methods to create and assign the `f410/t410` Filecoin address to Ethereum address. + +The subaddress of an `f410/t410` address is the original Ethereum address. Ethereum addresses can be cast as `f410` addresses, and vice-versa. The `f410/t410` address will be used for the Ethereum-compatible FVM (FEVM) development tools and applications built on FEVM. + +**Example** + +```plaintext +# An Ethereum wallet address. +0xd388ab098ed3e84c0d808776440b48f685198498 + +# The corresponding Filecoin address on Calibration. +t410f2oekwcmo2pueydmaq53eic2i62crtbeyuzx2gmy +``` + +If you have an Ethereum wallet address starting with `0x`, then the Ethereum Address Manager (EAM) will assign a corresponding `t410` Filecoin address to it. If you send 10 TFIL to `0xd388ab098ed3e84c0d808776440b48f685198498` using a wallet like MetaMask, you will receive 10 TFIL to your `t410f2oekwcmo2pueydmaq53eic2i62crtbeyuzx2gmy` address on Filecoin Calibration testnet. + +```plaintext +# A Filecoin smart contract address. +t410fl5qeigmkcytz7b6sqoojtcetqwf37dm4zv4aijq + +# The corresponding Ethereum smart contract address. +0x5f6044198a16279f87d2839c998893858bbf8d9c +``` + +Again, assume you have deployed a solidity smart contract on Filecoin Calibration.

This includes the Filecoin EVM runtime. Instead of the Filecoin EVM runtime charging gas according to the EVM spec for each EVM opcode executed, the Filecoin virtual machine (FVM) charges Filecoin gas for executing the EVM interpreter itself. The [How gas works](how-gas-works.md) page goes into this in more detail. Importantly, this means that Filecoin EVM runtime gas costs and EVM gas costs will be very different: + +1. EVM and Filecoin gas are different units of measurement and are not 1:1. Purely based on chain throughput (gas/second), the ratio of Ethereum gas to Filecoin gas is about 1:444. Expect Filecoin gas numbers to look _much_ larger than those in Ethereum. +2. Because Filecoin charges Filecoin gas for executing the Filecoin EVM runtime interpreter: + 1. Some instructions may be more expensive and/or cheaper in Filecoin EVM runtime than they are in the EVM. + 2. EVM instruction costs can depend on the exact Filecoin EVM runtime code-paths taken, and caching. + +{% hint style="danger" %} +⚠️ Filecoin gas costs are not set in stone and should never be hard-coded. Future network upgrades will break any smart contracts that depend on gas costs not changing. +{% endhint %} + +## Gas stipend + +Solidity calls `address.transfer` and `address.send` to grant a fixed gas stipend of 2300 Ethereum gas to the called contract. The Filecoin EVM runtime automatically detects such calls, and sets the gas limit to 10 million Filecoin gas. This is a relatively more generous limit than Ethereum’s, but it’s future-proof. You should expect the address called to be able to carry out more work than in Ethereum. + +## Self destruct + +Filecoin EVM runtime emulates EVM self-destruct behavior but isn’t able to entirely duplicate it: + +1. There is no gas refund for self-destruct. +2. On self-destruct, the contract is marked as self-destructed, but is not actually deleted from the Filecoin state-tree. Instead, it simply behaves as if it does not exist. It acts like an empty contract. +3. Unlike in the EVM, in Filecoin EVM runtime, self-destruct can _fail_ causing the executing contract to revert. Specifically, this can happen if the specified beneficiary address is an embedded [ID address](../../basics/the-blockchain/addresses.md) and no actor exists with the specified ID. +4. If funds are sent to a self-destructed contract after it self-destructs but before the end of the transaction, those funds remain with the self-destructed contract. In Ethereum, these funds would vanish after the transaction finishes executing. + +## CALLCODE + +The `CALLCODE` opcode has not been implemented. Use the newer `DELEGATECALL` opcode. + +## Bare-value sends + +In Ethereum, `SELFDESTRUCT` is the only way to send funds to a smart contract without giving the target smart contract a chance to execute code. + +In Filecoin, any actor can use `method 0`, also called a bare-value send, to transfer funds to any other actor without invoking the target actor’s code. You can think of this behavior as having the suggested [`PAY` opcode](https://eips.ethereum.org/EIPS/eip-5920) already implemented in Filecoin. + +## Precompiles + +The Filecoin EVM runtime, unlike Ethereum, does not usually enforce gas limits when calling precompiles. This means that it isn’t possible to prevent a precompile from consuming all remaining gas. The `call actor` and `call actor id` precompiles are the exception. However, they apply the passed gas limit to the actor call, not the entire precompile operation (i.e., the full precompile execution end-to-end can use more gas than specified, it’s only the final `send` to the target actor that will be limited). + +## Multiple Addresses + +In Filecoin, contracts generally have multiple addresses. Two of these address types, `f0` and `f410f`, can be converted to 0x-style (Ethereum) addresses which can be used in the `CALL` opcode. See [Converting to a 0x-style address](address-types.md#converting-to-a-0x-style-address) for details on how these addresses are derived. + +Importantly, this means that any contract can be called by either its “normal” EVM address (corresponding to the contract’s `f410f` address) or its “masked ID address” (corresponding from the contract’s `f0` address). + +However, the addresses returned by the CALLER, ORIGIN, and ADDRESS instructions will always be the same for the same contract. + +* The ADDRESS will always be derived from the executing contract’s `f410f` address, even if the contract was called via a masked ID address. +* The CALLER/ORIGIN will be derived from the caller/origin’s `f410f` address, if the caller/origin is an Ethereum-style account or an EVM smart contract. Otherwise, the caller/origin’s “masked ID address” (derived from their `f0` address) will be used. + +## Deferred execution model + +When calling an Ethereum method that allows the user to ask for the `latest` block, Filecoin will return the `chain head` - `1` block. This behavior was implemented for compatibility with the deferred execution mode that Filecoin uses. In this mode, messages submitted at a given `height` are only processed at `height` + `1`. This means that receipts for a block produced at `height` are only available at `height` + `1`. diff --git a/smart-contracts/filecoin-evm-runtime/filforwarder.md b/smart-contracts/filecoin-evm-runtime/filforwarder.md new file mode 100644 index 000000000..2f6520f6e --- /dev/null +++ b/smart-contracts/filecoin-evm-runtime/filforwarder.md @@ -0,0 +1,146 @@ +--- +description: >- + The FilFowarder is a smart contract that lets users transfer FIL from an + Ethereum-based f4 address to a Filecoin address of a different type. +--- + +# FILForwarder + +## The problem + +Filecoin has multiple [address spaces](../../basics/the-blockchain/addresses.md): `f0`, `f1`, `f2`, `f3`, and `f4`.

Our gas parameters are: + +* `GasUsage` = `1000` attoFIL +* `BaseFee` = `20` attoFIL +* `Gas limit` = `2000` attoFIL +* `Gas premium` = `5` attoFIL + +The total fee is `(GasUsage × BaseFee) + (Gaslimit x GasPremium)`: + +```plaintext + 1000 +x 20 += 20000 + + 2000 +x 5 += 10000 + + 20000 ++ 10000 += 30000 attoFIL +``` + +Additionally, the message sender can also set the `GasFeeCap` parameter they are willing to pay. If the sender sets the `GasLimit` too high, the network will compute the amount of gas to be refunded and the amount of gas to be burned as `OverEstimationBurn`. + +## Estimate gas + +Filecoin nodes, such as Lotus, have several JSON-API API endpoints designed to help developers estimate gas usage. The available JSON-RPC APIs are: + +* `GasEstimateMessageGas`: estimate gas values for a message without any gas fields set, including GasLimit, GasPremium, and GasFeeCap. Returns a message object with those gas fields set. +* `GasEstimateGasLimit` takes the input message and estimates the `GasLimit` based on the execution cost as well as a transaction multiplier. +* `GasEstimateGasPremium`: estimates what `GasPremium` price you should set to ensure a message will be included in `N` epochs. The smaller `N` is the larger `GasPremium` is likely to be. +* `GasEstimateFeeCap`: estimate the `GasFeeCap` according to `BaseFee` in the parent blocks. + +If you want to learn more about how to use those JSON-RPC APIs for the Filecoin gas model, please check the [JSON RPC API docs for Gas](../../reference/json-rpc/). + +Gas estimation varies from network to network. For example, the `BaseFee` on mainnet is different from the `BaseFee` on the Calibration testnet. + +If you’d rather not calculate and estimate gas for every message, you can just leave the optional fields unset. The gas fields will be estimated and set when the message is pushed to the mempool. + +## Ethereum compatibility + +Since Filecoin is fully EVM-compatible, Filecoin nodes also provide Ethereum-compatible APIs to support gas estimation: + +* [EthEstimateGas](../../reference/json-rpc/eth.md#ethestimategas): generates and returns an estimate of how much gas is necessary to allow the transaction to complete. +* [EthMaxPriorityFeePerGas](../../reference/json-rpc/eth.md#ethmaxpriorityfeepergas): returns a fee per gas that is an estimate of how much you can pay as a priority fee, or “tip”, to get a transaction included in the current block. + +To request the current max priority fee in the network, you can send a request to a public Filecoin endpoint: + +```shell +curl --location --request POST 'https://api.calibration.node.glif.io/rpc/v1' \ +--header 'Content-Type: application/json' \ +--data-raw '{ + "jsonrpc":"2.0", + "method":"eth_maxPriorityFeePerGas", + "params": null, + "id":1 +}' | jq +``` + +This will output something like: + +```plaintext +{ + "jsonrpc": "2.0", + "result": "0x31157", + "id": 1 +} +``` + +You can convert the `result` field from hexadecimal to base 10 in your terminal. Take the `result` output and remove the `0x` from the start.

If you are looking for more technical FAQs, please head to [Filecoin Community Discussion](https://github.com/filecoin-project/community/discussions/categories/q-a). + +## **What is FVM** + +The FVM (Filecoin virtual machine) enables developers to write and deploy custom code to run on top of the Filecoin blockchain. This means developers can create apps, markets, and organizations built around data stored on Filecoin. + +## **What broader implications does FVM have** + +FVM allows us to think about data stored on Filecoin differently. Apps can now build a new layer on the Filecoin network to enable trading, lending, data derivatives, and decentralized organizations built around datasets. + +## **What problems does FVM solve** + +FVM can create incentives to solve problems that Filecoin participants face today around data replication, data aggregation, and liquidity for miners. Beyond these, there is a long tail of data storage and retrieval problems that will also be resolved by user programmability on top of Filecoin. + +## **How does Aptos compare to FVM** + +[Aptos](https://aptoslabs.com/) is a Move-based L1 chain, whereas FVM is a WASM runtime on the Filecoin chain. The latter comes with an EVM right of the box; the former does not. The FVM also supports programmable storage with deals on Filecoin. + +## **How does the FVM directly interact with data on Filecoin** + +The FVM operates on blockchain state data — it does _not_ operate on data stored in the Filecoin network. This is because access to that data depends on network requests, an unsealed copy’s availability, and the SPs’ availability to supply that data. + +Access and manipulation of data stored in the network will happen via L2 solutions, for example, retrieval networks or compute-over-data networks, e.g., Saturn or CoD. + +## **How do other EVMs compare to FEVM** + +Unlike other EVM chains, FEVM specifically allows you to write contracts that orchestrate programmable storage. This means contracts that can coordinate storage providers, data health, perpetual storage mechanisms, and more. Other EVM chains do not have direct access to Filecoin blockchain state data. + +## **What is an actor** + +An actor is code that the Filecoin virtual machine can run. Actors are also referred to as smart contracts. + +## **What are built-in actors** + +[Built-in actors](https://github.com/filecoin-project/builtin-actors) are code that come precompilied into the Filecoin clients and can be run using the FVM.

Reduce costs of writing to storage from an EVM smart contract to a separate storage service. + +## **Why FEVM vs native FVM** + +FEVM allows Solidity developers to easily write/port actors to the FVM using the tools that have already been introduced in the Ethereum ecosystem. + +## **What applications make FVM/FEVM unique** + +Applications that natively make use of storage contracts. Perpetual storage contracts, Data DAOs, etc. + +## **What is perpetual storage** + +Perpetual storage is a unique actor design paradigm only available on the FVM that allows users the ability to renew Filecoin storage deals and to keep them active indefinitely. This could be achieved by using a Decentralized Autonomous Organization (DAO) structure for example. + +## **What are Data DAOs** + +Data DAOs are a unique design paradigm FVM developers could create which use Filecoin storage to store all their data instead of a service like AWS (which is currently used). + +## **Is FVM part of Filecoin clients like Lotus** + +Yes. + +## **Do I have to install Lotus to work with FVM** + +Not necessarily.

Bridges can be built to top of the FEVM which connect it to other blockchains however. + +## **How is the Filecoin network accessed through Solidity** + +When an EVM is deployed to FEVM, it is compiled with WASM and an actor instance is created in FEVM that runs the EVM bytecode.

It is + maintained by Protocol Labs. Understanding the components of Lotus is + necessary for building well-balanced storage provider. +--- + +# Lotus components + +The diagram below shows the major components of Lotus: + +
    + +The following components are the most important to understand: + +* [Lotus daemon](lotus-components.md#lotus-daemon) +* [Lotus miner](lotus-components.md#lotus-miner) +* [Lotus worker](lotus-components.md#lotus-worker) + +## Lotus daemon + +The daemon is a key Lotus component that does the following: + +* Syncs the chain +* Holds the wallets of the storage provider + +The machine running the Lotus daemon must be connected to the public internet for the storage provider to function. See the [Lotus documentation](https://lotus.filecoin.io/storage-providers/setup/initialize/#connectivity-to-the-storage-provider) for more in-depth information on connectivity requirements. + +### Syncing the chain + +Syncing the chain is a key role of the daemon. It communicates with the other nodes on the network by sending messages, which are, in turn, collected into [blocks](../../reference/general/glossary.md#block). These blocks are then collected into [tipsets](../../reference/general/glossary.md#tipset). Your Lotus daemon receives the messages on-chain, enabling you to maintain consensus about the state of the Filecoin network with all the other participants. + +Due to the growth in the size of the chain since its genesis, it is not advised for storage providers to sync the entire history of the network. Instead, providers should use the available [lightweight snapshots](https://lotus.filecoin.io/kb/chain-snapshots/) to import the most recent messages. One exception in which a provider would need to sync the entire chain would be to run a [blockchain explorer](../../networks/mainnet/explorers.md). + +Synced chain data should be stored on an SSD; however, faster NVMe drives are strongly recommended. A slow chain sync can lead to delays in critical messages being sent on-chain from your Lotus miner, resulting in the faulting of sectors and the slashing of collateral. + +Another important consideration is the size of the file system and available free space. Because the Filecoin chain grows as much as 50GB a day, any available space will eventually fill up. It is up to storage providers to manage the size of the chain on disk and prune it as needed. Solutions like [SplitStore](https://lotus.filecoin.io/lotus/configure/splitstore/) (enabled by default) and [compacting](https://lotus.filecoin.io/lotus/manage/chain-management/#compacting-the-chain-data) reduce the storage space used by the chain. Compacting involves replacing the built-up chain data with a recent lightweight snapshot. + +### Holding wallets + +Another key role of the Lotus daemon is to host the Filecoin wallets that are required to run a storage provider (SP). As an SP, you will need a minimum of 2 wallets: an _owner wallet_ and a _worker wallet_. A third wallet called the _control_ wallet is required to scale your operations in a production environment. + +To keep wallets safe, providers should consider physical access, network access, software security, and secure backups. As with any cryptocurrency wallet, access to the private key means access to your funds. Lotus supports [Ledger hardware wallets](https://lotus.filecoin.io/lotus/manage/ledger/), the use of which is recommended. The worker and control wallets can not be kept on a hardware device because Lotus requires frequent access to those types of wallets. For instance, Lotus may require access to a worker or control wallet to send [WindowPoSt](../../reference/general/glossary.md#window-proof-of-spacetime-windowpost) proofs on-chain. + +For information on how to view wallets and their funds, see [Helpful commands](lotus-components.md#view-wallets-and-funds). For information and instructions on integrating your Ledger device with Lotus, see the following video: + +{% embed url="https://www.youtube.com/watch?v=u_S5F6WyBAU" %} + +#### **Control wallets** + +Control wallets are required to scale your operations in a production environment. In production, only using the general worker wallet increases the risk of message congestion, which can result in delayed message delivery on-chain and potential sector faulting, slashing, or lost block rewards. It is recommended that providers create wallets for each subprocess. There are five different types of control wallets a storage provider can create: + +* PoSt wallet +* PreCommit wallet +* Commit wallet +* Publish storage deals wallet +* Terminate wallet + +## Lotus miner + +The Lotus miner, often referred to using the daemon naming syntax `lotus-miner`, is the process that coordinates most of the storage provider activities. It has 3 main responsibilities: + +* Storing sectors and data +* Scheduling jobs +* Proving the stored data + +### Storing sectors and data + +Storage Providers on the Filecoin network store sectors. There are two types of sectors that a provider may store: + +* Sealed sectors: these sectors may or may not actually contain data, but they provide capacity to the network, for which the provider is rewarded. +* Unsealed sectors: used when storing data deals, as retrievals happen from unsealed sectors. + +Originally, `lotus-miner` was the component with storage access. This resulted in `lotus-miner` hardware using internal disks, directly attached storage shelves like [JBODs](https://en.wikipedia.org/wiki/Non-RAID\_drive\_architectures#JBOD), Network-Attached-Storage (NAS), or a storage cluster. However, this design introduced a bottleneck on the Lotus miner. + +More recently, Lotus has added a more scalable storage access solution in which workers can also be assigned storage access. This removes the bottleneck from the Lotus miner. Low-latency storage access is critical because of the impact on storage-proving processes. + +Keeping a backup of your sealed sectors, the cache directory, and any unsealed sectors is crucial. Additionally, you should keep a backup of the `sectorstore.json` file that lives under your storage path. The `sectorestore.json` file is required to restore your system in the event of a failure. You can read more about the `sectorstore.json` file in the [Lotus docs](https://lotus.filecoin.io/). + +It is also imperative to have at least a daily backup of your `lotus-miner` state. Backups can be made with: + +```shell +lotus-miner backup +``` + +{% hint style="info" %} +For information on how to back up Lotus miner state, see [Helpful commands](lotus-components.md#backup-lotus-miner-state). +{% endhint %} + +The `sectorstore.json` file, which lives under your storage path, is also required for restoration in the event of a failure. You can read more about the file in the [Lotus docs](https://lotus.filecoin.io/storage-providers/seal-workers/seal-workers/#sector-storage-groups). + +## Scheduling jobs + +Another key responsibility of the Lotus Miner is the scheduling of jobs for the [sealing pipeline](sealing-pipeline.md) and storage proving. + +For information on how to view scheduled jobs, see [View scheduled jobs](lotus-components.md#view-scheduled-jobs). For information on how to see the workers on which the miner can schedule jobs, see [View available workers](lotus-components.md#view-available-workers). + +### Storage proving + +One of the most important roles of `lotus-miner` is the [Storage proving](lotus-components.md#storage-proving). Both [WindowPoSt](../../reference/general/glossary.md#window-proof-of-spacetime-windowpost) and [WinningPoSt](../../reference/general/glossary.md#winning-proof-of-spacetime-winningpost) processes are usually handled by the `lotus-miner` process. For scalability and reliability purposes it is now also possible to run these proving processes on dedicated servers (proving workers) instead of using the Lotus miner. + +The proving processes require low-latency access to sealed sectors. The proving challenge requires a GPU to run on. The resulting `zkProof` will be sent to the chain in a message. Messages must arrive within 30 minutes for WindowPoSt, and 30 seconds for WinningPoSt. It is extremely important that providers properly size and configure the proving workers, whether they are using just the Lotus miner or separate workers. Additionally, dedicated wallets, described in [Control wallets](lotus-components.md#control-wallets), should be set up for these processes. + +Always check if there are upcoming proving deadlines before halting any services for maintenance. For detailed instructions, refer to the [Lotus maintenance guide](https://lotus.filecoin.io/storage-providers/operate/maintenance/). + +For information on how to check if there are upcoming proving deadlines, see [Helpful commands](lotus-components.md#helpful-commands). + +## Lotus worker + +The Lotus worker is another important component of the Lotus architecture. There can be - and most likely will be - multiple workers in a single storage provider setup. Assigning specific roles to each worker enables higher throughput, [sealing rate](sealing-rate.md), and improved redundancy. + +As mentioned above, proving tasks can be assigned to dedicated workers, and workers can also get storage access. The remaining worker tasks encompass running a [sealing pipeline](sealing-pipeline.md), which is discussed in the next section. + +## Helpful commands + +The following commands can help storage providers with their setup. + +### Backup Lotus miner state + +It is imperative to have at least one daily backup of your Lotus miner state.

    + +### AddPiece + +The sealing pipeline begins with _AddPiece_ (AP), where the pipeline takes a _Piece_ and prepares it into the sealing scratch space for the _PreCommit 1_ task (PC1) to take over. In Filecoin, a _Piece_ is data in CAR-file format produced by an [IPLD DAG](https://ipld.io) with a corresponding `PayloadCID` and `PieceCID`. The maximum Piece size is equal to the sector size, which is either 32 GiB or 64 GiB. If the content is larger than the sector size, it must be split into more than one `PieceCID` during data preparation. + +The AddPiece process is not a very intensive process and only uses some CPU cores; it doesn’t require the use of a GPU. It is typically co-located on a server with other worker processes from the sealing pipeline. As PC1 is the next process in the sealing pipeline, running AddPiece on the same server as the PC1 process is a logical architecture configuration. + +Consider limiting the AP process to a few cores by using the [`taskset` command](https://man7.org/linux/man-pages/man1/taskset.1.html), where `` is the range on which cores the process needs to run on: + +```shell +taskset -c lotus-worker run ... +``` + +### PreCommit 1 + +PreCommit 1 (PC1) is the most intensive process of the entire sealing pipeline. PC1 is the step in which a sector, regardless of whether it contains data or not, is cryptographically secured. The worker process loads cryptographic parameters from a cache location, which should be stored on enterprise NVMe for latency reduction. These parameters are then used to run Proof-of-Replication (PoRep) SDR encoding against the sector that was put into the sealing scratch space. This task is single-threaded and very CPU intensive, so it requires a CPU with SHA256 extensions. Typical CPUs that meet this requirement include the AMD Epyc Milan/Rome or an Intel Xeon Ice Lake with 32 cores or more. + +Using the scratch space, the PC1 task will create 11 layers of the sector. Storage providers must host scratch space for this on enterprise NVMe. This means that: + +* Every sector consumes memory equal to 1+11 times its size on the scratch volume. +* For a 32 GiB sector, PC1 requires 384 GiB on the scratch volume +* For a 64 GiB sector, PC1 requires 768 GiB. + +In order to seal at a decent rate and to make use of all the sealing capacity in a PC1 server, you will run multiple PC1 workers in parallel on a system. You can learn more about this in the chapter on [Sealing Rate](sealing-rate.md). Sealing several sectors multiplies the requirements on CPU cores, RAM, and scratch space by the number of sectors being sealed in parallel. + +In order to achieve a decent sealing rate and make use of all sealing capacity in a PC1 server, storage providers should run multiple PC1 processes in parallel on a system. More information on this can be found in [Sealing Rate](sealing-rate.md). + +The process of sealing a single 32 GiB sector takes roughly **3 hours**. + +### PreCommit 2 + +When PC1 has been completed on a given sector, the entire scratch space for that sector is moved over to the _PreCommit 2 (PC2)_ task. This task is typically executed on a different server than the PC1 server because it behaves differently. In short, PC2 validates PC1 using the Poseidon hashing algorithm over the Merkle Tree DAG that was created in PC1. As mentioned in the previous section, the entire scratch space is either 384 GiB or 768 GiB, depending on the sector size. + +Where PC1 is CPU-intensive, PC2 is executed on GPU. This task is also notably shorter in duration than PC1, typically 10 to 20 minutes on a capable GPU. This requires a GPU with at least 10 GiB of memory and 3500+ CUDA cores or shading units, in the case of Nvidia. Storage providers can use slower GPUs, but this may create a bottleneck in the sealing pipeline. + +For best performance, compile Lotus with CUDA support instead of OpenCL. For further information, see the Lotus [CUDA Setup](https://lotus.filecoin.io/tutorials/lotus-miner/cuda/) + +In the case of a [Snap Deal](../filecoin-deals/snap-deals.md), an existing committed capacity sector is filled with data. When this happens, the entire PC1 task does not run again; however, the snapping process employs PC1’s `replica-update` and `prove-replica-update` to add the data to the sector. This can run on the PC2 worker or on a separate worker depending on your sealing pipeline capacity. + +When PC2 is complete for a sector, a _precommit_ message is posted on-chain. If batching is configured, Lotus will batch these messages to avoid sending messages to the chain for every single sector. In addition, there is a configurable timeout interval, after which the message will be sent on-chain. This timeout is set to 24 hours by default. These configuration parameters are found in the `.lotusminer/config.toml` file. + +If you want to force the pre-commit message on-chain for testing purposes, run: + +```shell +lotus-miner sectors batching precommit --publish-now +``` + +The sealed sector and its 11 layers are kept on the scratch volume until Commit 2 (C2) is complete. + +### WaitSeed + +WaitSeed is not an actual task that is executed, but it is a step in the pipeline in which the blockchain forces the pipeline to wait for 150 epochs as a built-in security mechanism. With Filecoin’s 30 second epochs, this means 75 minutes must elapse between PC2 and the next task, Commit 1 (C1). + +### Commit 1 + +The Commit 1 (C1) phase is an intermediate phase that performs the preparation necessary to generate a proof. It is CPU-bound and typically completes in seconds. It is recommended that storage providers run this process on the server where PC2 is running. + +### Commit 2 + +The last and final step in the sealing pipeline is Commit 2 (C2). This step involves the creation of zk-SNARK proof. Like PC2, this task is GPU-bound and is, therefore, best co-located with the PC2 task. + +Finally, the proof is committed on-chain in a message. As with the pre-commit messages, the commit messages are batched and held for 24 hours by default before committing on-chain to avoid sending messages for each and every sector. You can again avoid batching by running: + +```shell +lotus-miner sectors batching commit --publish-now +``` + +Finally, the sealed sector is stored in the miner’s long-term storage space, along with unsealed sectors, which are required for retrievals if configured to do so. diff --git a/storage-providers/architecture/sealing-rate.md b/storage-providers/architecture/sealing-rate.md new file mode 100644 index 000000000..2c6018355 --- /dev/null +++ b/storage-providers/architecture/sealing-rate.md @@ -0,0 +1,44 @@ +--- +description: >- + The rate at which storage providers complete the sealing pipeline process is + called the sealing rate sealing capacity. This page describes considerations + and advice in regards to sealing rate. +--- + +# Sealing rate + +## Cost + +When setting up their business, storage providers must determine how fast they should seal and, thus, how much sealing hardware they should buy. In other words, the cost is an important factor in determining a storage provider’s sealing rate. For example, suppose you have an initial storage capacity of 100 TiB, which would account for 1 PiB [QAP](../../reference/general/glossary.md#quality-adjusted-storage-power) if all the sectors contain Filecoin Plus verified deals. If your sealing capacity is 2.5 TiB per day, you will seal your full 100 TiB in 40 days. Is it worth investing in double the sealing capacity to fill your storage in just 20 days? It might be if you are planning to grow way beyond 100 TiB. This is an example of the sort of cost considerations storage providers must factor in tuning the sealing rate. + +## Customer expectations + +A common reason that a storage provider may want or need a faster sealing rate is customer expectations. When you take on a customer deal, there are often requirements to seal a dataset of a certain size within a certain time window. If you are a new storage provider with 2.5 TiB per day in sealing capacity, you cannot take on a deal of 2 PiB that needs to be on-chain in 1 month; at the very least, you could not take the deal using your own sealing infrastructure. Instead, you can use a [Sealing-as-a-service provider](sealing-as-a-service.md), which can help you scale your sealing capabilities. + +## Balancing the sealing pipeline + +When designing their sealing pipeline, storage providers should consider bottlenecks, the grouping of similar tasks, and scaling out. + +### Bottlenecks + +The art of building a well-balanced sealing pipeline means having the bottlenecks where you expect them to be; any non-trivial piece of infrastructure always contains some kind of bottleneck. Ideally, you should design your systems so that the PC1 process is the bottleneck. By doing this, all other components are matched to the capacity required to perform PC1. With PC1 being the most resource-intensive task in the pipeline, it makes the most sense to architect a solution around this bottleneck. Knowing exactly how much sealing capacity you can get from your PC1 servers is vital so you can match the rest of your infrastructure to this throughput. + +Assuming you obtain maximum hardware utilization from your PC1 server to seal 15 sectors in parallel, that would mean a sealing rate of 3.75 TiB per day. The calculation is described below: + +```plaintext +15 sectors x 32 GiB / 3 hours PC1 runtime x 24 hours / 1024 = 3.75 TiB /day +``` + +### Grouping similar tasks + +While a Lotus worker can run all of the various tasks in the sealing pipeline, different storage provider configurations may split tasks between workers. Because some tasks are similar in behavior and others are insignificant in terms of resource consumption, it makes sense to group like-tasks together on the same worker. + +A common grouping is _AddPiece (AP)_ and PreCommit1 (PC1) because AP essentially prepares the data for the PC1 task. If you have dedicated hardware for PreCommit2 (PC2), your scratch content will move to that other server. If you are grouping PC1 and PC2 on the same server, you won’t have the sealing scratch copied, but you will need a larger NVMe volume. Eventually, you may run out of sealing scratch space and not be able to start sealing additional sectors. + +As PC1 is CPU-bound and PC2 is GPU-bound, this is another good reason to separate those tasks into dedicated hardware, especially if you are planning to scale. Because PC2 is GPU-bound, it makes sense to have PC2, C1, and C2 colocated on the same worker. + +Another rule of thumb is to have two PC2 workers for every PC1 worker in your setup. The _WaitSeed_ phase occurs after PC2, which locks the scratch space for a sector until C1 and C2. In order to keep sealing sectors in PC1, PC2 must have sufficient capacity. + +### Scaling out + +A storage provider’s sealing capacity scales linearly with the hardware you add to it. For example, if your current setup allows for a sealing rate of 3 TiB per day, doubling the number of workers could bring you to 6 TiB per day. This requires that all components of your infrastructure are able to handle this additional throughput. Using [Sealing-as-a-Service providers](sealing-as-a-service.md) allows you to scale your sealing capacity without adding more hardware. diff --git a/storage-providers/basics/README.md b/storage-providers/basics/README.md new file mode 100644 index 000000000..6fdfd9b0d --- /dev/null +++ b/storage-providers/basics/README.md @@ -0,0 +1,53 @@ +--- +description: >- + This page will help you understand how to plan a profitable business, design a + suitable storage provider architecture, and make the right hardware + investments. +--- + +# Basics + +The Filecoin network provides decentralized data storage and makes sure data is verified, always available, and immutable.

To achieve this, it’s crucial to add valuable data to the network. Filecoin Plus (Fil+) is a social trust program encouraging storage providers to store data in _verified deals_. A deal becomes _verified_ after the data owner (client) completes a verification process, where community _notaries_ assess the client’s use of Filecoin to determine its relevance and value to the Filecoin mission: storing and preserving humanity’s vital data.

However, many large storage providers use up to 100 GB internet connections. \`\`\` + +Data preparation, which involves separating files and folders in CAR files, is time-consuming and requires expertise.

A backup strategy is only as good as the last successful restore. +--- + +# Backup and disaster recovery + +It is crucial to have a backup of any production system. It is even more crucial to be able to restore from that backup. These concepts are vital to a Filecoin storage provider because not only are you storing customer data for which you have (on-chain) contracts, you have also pledged a large amount of collateral for that data. + +If you are unable to restore your Lotus miner and start proving your storage on-chain, you risk losing a lot of money.

HA will protect against unplanned unavailability in many cases, such as a system failure. It will **not** protect you against data corruption, data loss, ransomware, or a complete disaster at the datacenter level. + +Backups and (tested) restores are the basis for a DR (disaster recovery) plan and should be a major point of attention for any Filecoin storage provider, regardless of your size of operation. + +## Recovery Time Objective (RTO) and Recovery Point Objective + +When planning for backup and recovery, the terms RPO and RTO are important concepts to know about. + +* **Recovery Time Objective (RTO)** is the time taken to recover a certain application or dataset in the event of a failure. Fast recovery means a shorter RTO (typically measured in hours/minutes/seconds). Enterprises plan for very short RTOs when downtime is not acceptable to their business. Application and file system snapshots typically provide the lowest possible RTO. +* **Recovery Point Objective (RPO)** is the last known working backup from which you can recover. A shorter RPO means the time between the last backup and the failure is short. Enterprises plan for very short RPOs for systems and data that changes very often (like databases). Synchronous replication of systems and data typically provides the lowest possible RPO. + +### RPO/RTO for storage providers + +Although ‘RPO zero’ and ‘RTO zero’ are the ideal, in practice it is rarely economical. DR planning requires compromises and if you are a storage provider you need to consider cost versus RPO. + +RTO is typically less concerning for storage providers. The most critical parts to recover are your sealed storage and your wallets. Wallet addresses typically do not change, so the only thing to worry about is your sealed storage. With storage level snapshots (such as ZFS snapshots), you can reduce your RTO to almost zero. + +For RPO, although synchronous replication, together with snapshots, can reduce RPO to nearly zero, that is not a cost-efficient solution. Asynchronous replication of sealed storage is the most viable option if you are running at small-to-medium scale. Once you grow beyond 10PB of storage, even replicating the data will become an expensive solution. + +In such cases you might want to look into _storage cluster_ solutions with built-in redundancy. Very large storage providers will operate [Ceph clusters](https://en.wikipedia.org/wiki/Ceph\_\(software\)) or other solutions with built-in _erasure coding_. Although this does more become more like a HA setup than a DR setup, at scale, it becomes the only economically viable option. + +Running a storage cluster comes with its own operational challenges though, which does not make this a good fit for small-to-medium setups. + +### RPO/RTO for customers + +Both storage providers and data owners (customers) should look at RPO and RTO options. As a customer, you can achieve HA/DR by having multiple copies of your data stored (and proven) across multiple storage providers. In the event of data loss at one provider, other providers will hold a copy of your data from which you can retrieve. As a customer, you choose how much redundancy you need, by doing storage deals with more providers. + +RTO for data owners is a matter of how fast the storage provider(s) can provide you the data. + +* Do your storage providers offer “fast retrieval” of the data through unsealed copies? If not, the unsealing process (typically multiple hours) must be calculated into the RTO. +* Do your storage providers offer retrieval through [Saturn, (the Web3 CDN)](https://saturn.tech) for ultra-fast retrieval? +* Do your storage providers pin your data on IPFS, in addition to storing it on Filecoin? + +RPO for data owners is less of a concern, especially once the data is sealed. The Filecoin blockchain will enforce availability and durability of the data being stored, once it is sealed. It is therefore important, as a data owner, to know how fast your storage provider can prove the data on-chain. + +## Backup techniques + +* A first level of protection comes from ZFS (if you are using ZFS as the file system for your storage). Having ZFS snapshots available protects you against data loss caused by human error or tech failure, and potentially even against ransomware. Other file systems typically also have a way to make snapshots, albeit not as efficiently as ZFS. +* A second level of defense comes from a dedicated backup system. Not only should you have backup storage (on a different storage array than the original data), you also need to have a backup server that can at a minimum run the Lotus daemon, Lotus miner and 1 WindowPoSt worker (note: this requires a GPU). With that you can sync the chain, offer retrievals and prove your storage on-chain, from your backup system, whilst you bring your primary back online. +* An alternative technique to having a dedicated backup system and copy is to have a storage cluster. This still requires a backup system to run the Lotus daemon, Lotus miner and PoST worker on. Implementing a storage cluster is usually only done for large-scale deployments as it comes with additional operational tasks. + +For maximum resilience, you could host your backup system (server + storage) in a different datacenter than your primary system. diff --git a/storage-providers/infrastructure/network.md b/storage-providers/infrastructure/network.md new file mode 100644 index 000000000..9d005926d --- /dev/null +++ b/storage-providers/infrastructure/network.md @@ -0,0 +1,32 @@ +--- +description: >- + This page covers topics related to internet bandwidth requirements, LAN + bandwidth considerations, the use of VLANs for network traffic separation, + network redundancy measures, and common topologies. +--- + +# Network + +## Internet bandwidth + +The amount of internet bandwidth required for a network largely depends on the size of the organization and customer expectations.

    1 PiB raw reference architecture.

    + +The following reference architecture is designed for 1 PiB of raw sectors or raw data to be stored. Let’s discuss the various design choices of this architecture. + +### Virtual machines + +* 32 CPU Cores +* 512 GB RAM +* 8x 2 TB SSD storage +* 2x 10 GbE ethernet NICs + +Lotus daemon and Boost run as Virtual Machines in this architecture. The advantages of virtualization are well-known, including easy reconfiguration of parameters (CPU, memory, disk) and portability. The daemon is not a very intensive process by itself, but must be available at all times. We recommend having a second daemon running as another VM or on backup infrastructure to which you can fail over. + +Boost is a resource-intensive process, especially when deals are being ingested over the internet. It also feeds data payload of the deals into the Lotus miner. + +We recommend 12-16 cores per VM and 128 GiB of memory. Lotus daemon and Boost need to run on fast storage (SSD or faster). The capacity requirements of Boost depend on the size of deals you are accepting as a storage provider. Its capacity must be sufficient to be landing space for deals until the data can be processed by your sealing cluster in the backend. + +Both Lotus daemon and Boost require public internet connectivity. In the case of Boost you also need to consider bandwidth. Depending on the deal size you are accepting, you might require 1 Gbps or 10 Gbps internet bandwidth. + +### Lotus miner + +* 16 CPU Cores +* 256 GB RAM +* 2x 1TB SSD storage +* 2x 10 GbE ethernet NICs + +Lotus miner becomes a less intensive process with dedicated PoST workers separated from it (as in this design). If you use a dedicated storage server or NAS system as the storage target for your sealed and unsealed sectors, Lotus miner eventually could also become a VM. This requires additional CPU and memory on the hypervisor host. + +We opted for a standalone Lotus miner in this design and gave it 256 GiB of memory. This is because we operate ZFS at the storage layer, which requires a lot of memory for caching. Lotus miner has enough with 128 GiB of memory when you opt for a dedicated storage server or NAS system for your storage. + +### SATA Storage + +In this architecture we have attached storage shelves to the Lotus miner with 2.4 PiB of usable capacity. This is the capacity after the creation of a RAIDZ2 file system (double parity). We recommend vdevs of 12 disks wide. In RAIDZ2 this results in 10 data disks and 2 parity disks. Storage systems also don’t behave well at 100% used capacity, so we designed for 20% extra capacity. + +### PoST workers + +* 16 CPU Cores +* 128 GB RAM +* 2x 1TB SSD storage +* 1x GPU 10+ GB memory, 3500+ CUDA cores +* 2x 10 GbE ethernet NICs + +We have split off the Winning PoST and Window PoST tasks from the Lotus miner. Using dedicated systems for those processes increase the likelihood of winning block rewards and reduces the likelihood of missing a proving deadline. For redundancy, you can run a standby WindowPoSt worker on the WinningPoSt server and vice versa. + +PoST workers require 128 GiB of memory at the minimum and require a capable GPU with 10GB of memory and 3500 or more CUDA cores. + +### Sealing workers + +The sealing workers require the most attention during the design of a solution. Their performance will define the sealing rate of your setup, and hence, how fast you can onboard client deals. + +Keep in mind that using [Sealing-as-a-Service](../architecture/sealing-as-a-service.md) reduces the requirements to have a fast performing sealing setup. In this design, however, we plan for an on-premise sealing setup of maximum 7 TiB/day. This theoretical sealing capacity is based on the entire sealing setup running at full speed for 24 hrs/day. + +**AP / PC1 worker** + +* 32 CPU Cores **with SHA-extensions** +* 1 TB RAM +* 2x 1TB SSD OS storage +* 15+ TB U.3 NVMe sealing / scratch storage +* 2x 10 GbE (or faster) ethernet NICs + +We put the AddPiece and PreCommit1 tasks together on a first worker. This makes sense because AddPiece prepares the scratch space that will be used by the PC1 tasks thereafter. The first critical hardware component for PC1 is the CPU. This must be a CPU with SHA-256 extensions. Most storage providers opt for AMD Epyc (Rome, Milan or Genova) processors, although Ice Lake and newer Intel Xeon processors also support these extensions. + +To verify if your CPU has the necessary extensions, run: + +```shell +cat /proc/cpuinfo | grep --color sha_ni +``` + +PC1 is a single-threaded process so we require enough CPU cores to run multiple PC1 tasks in parallel. This reference architecture has 32 cores in a PC1, which would allow for \~30 parallel PC1 processes. + +For this, we also need 1TB of memory in the PC1 server. + +Every PC1 processes requires approximately 450 GiB of sealing scratch space. This scratch space is vital to the performance of the entire sealing setup. It requires U.2 or U.3 NVMe media. For 30 parallel PC1 processes we then need \~15 TiB of scratch space. RAID protection on this volume is not mandatory, however losing 30 sectors during sealing and having to start over does have an impact on your sealing rate. + +**PC2 / C1 / C2 workers** + +* 32 CPU Cores +* 512 GB RAM +* 2x 1TB SSD +* 1x GPU 10+ GB memory, 3500+ CUDA cores +* 2x 10 GbE (or faster) + +The next step in the sealing pipeline is PreCommit2 (PC2). You could decide to keep it together with PC1, but given the size of our setup (1 PiB) and the likely requirement to scale beyond that later, we split off PC2 in this architecture. + +We plan for twice the amount of PC2 workers compared to PC1, as explained under [sealing rate](../architecture/sealing-rate.md). Apart from the memory requirements this process specifically requires a capable GPU with preferably 24GB of memory and 6000 or more CUDA cores. + +The scratch space contents from PC1 is copied over to the PC2 worker. This PC2 worker also requires fast NVMe scratch space. Since we plan for 2 PC2 workers against 1 PC1 worker, the capacity of the scratch space per PC2 worker is half of the total scratch space capacity of the PC1 worker, 8 TiB in our case. + +C1 doesn’t require much attention for our architecture. C2 however requires a capable GPU again. + +## Solo storage providing + +Please take a look at the presentation Benjamin Hoejsbo from [PIKNIK](https://www.piknik.com) gave, in which solo storage provider setups are examined.

Since cost is an important aspect for storage providers, and you are dealing with cold storage mostly, you will be opting for SATA disks is RAID configurations that favor capacity (and read performance). This leads to RAID5, RAID6, RAIDZ and RAIDZ2. Double parity configurations like RAID6 and RAIDZ2 are preferred. + +The _width of a volume_ is defined by how many spindles (SATA disks) there are in a RAID group. Typical configurations range between 10+2 and 13+2 disks in a group (in a VDEV in the case of ZFS). + +## RAID implications + +Although RAIDZ2 provides high fault tolerance, configuring wide VDEVs also has an impact on performance and availability. ZFS performs an automatic healing task called _scrubbing_ which performs a checksum validation over the data and recovers from data corruption. This task is I/O intensive and might get in the way of other tasks that should get priority, like _storage proving_ of sealed sectors. + +Another implication of large RAID sets that gets aggravated with very large capacity per disk is the time it takes to rebuild. Rebuilding is the I/O intensive process that takes place when a disk in a RAID group is replaced (typically after a disk failed).

Physically separating sealed and unsealed copies has other advantages, which are explained in [Custom Storage Layout](https://lotus.filecoin.io/storage-providers/operate/custom-storage-layout/). + +## I/O Behavior + +Storage providers keep copies of sealed sectors and unsealed sectors (for fast retrieval) on their storage systems. However the I/O behavior on sealed sectors is very different from the I/O behavior on unsealed sectors. When [storage proving](../filecoin-economics/storage-proving.md) happens only a very small portion of the data is read by WindowPoSt. A large storage provider will have many sectors in multiple partitions for which WindowPoSt requires fast access to the disks. This is unusual I/O behavior for any storage system. + +The unsealed copies are used for fast retrieval of the data towards the customer. Large datasets in chunks of 32 GiB (or 64 GiB depending on the configured sector size) are read. + +In order to avoid different tasks competing for read I/O on disk it is recommended to create separate disk pools with their own VDEVs (when using ZFS) for sealed and unsealed copies. + +## Write performance + +Write access towards the storage also requires your attention. Depending how your storage array is connected (SAS or Ethernet) you will have different transfer speeds towards the sealed storage path. At a sealing capacity of 6 TiB/day you will effectively be writing 12 TiB/day towards the storage (6 TiB sealed, 6 TiB unsealed copies). Both your storage layout and your network need to be able to handle this. + +If this 12 TiB were equally spread across the 24 hrs of a day, this would already require 1.14 Gbps. + +> 12 TiB _1024 / 24 hr / 3600 sec_ 8 = 1.14 Gbps + +The sealing pipeline produces 32 GiB sectors (64 GiB depending on your configured sector size) which are written to the storage. If you configured _batching_ of the commit messages (to reduce total gas fees) then you will write multiple sectors towards disk at once. + +A minimum network bandwidth of 10 Gbps is recommended and write cache at the storage layer will be beneficial too. + +## Read performance + +Read performance is optimal when choosing for RAIDZ2 VDEVs of 10 to 15 disks.

The first and most obvious aspect is investment in hardware and FIL as collateral. Hardware is the backbone of any storage provider’s business, and ensuring that you have the right equipment to provide reliable and high-performance storage is critical. Additionally, FIL is the primary currency used within the Filecoin network, and as a storage provider, you need to ensure that you have a sufficient amount of FIL as collateral to cover your storage deals. + +As your business grows, the amount of hardware and FIL needed will increase, and it is important to have a clear plan for scaling your business. This involves not only investing in additional hardware and FIL but also managing operational costs such as electricity, cooling, and maintenance. Having a skilled business team that can manage and plan for these costs is essential. + +Another important aspect of running a storage provider business is managing your relationships with investors, venture capitalists, and banks. These organizations can provide much-needed funding to help grow your business, but they will only invest if they are confident in your ability to manage your business effectively. This means having a strong business plan, a skilled team, and a clear strategy for growth. + +In summary, the business aspects of running a storage provider business are critical to its success. This involves managing investments in hardware and FIL, planning for scalability and managing operational costs, and building strong relationships with investors, venture capitalists, and banks. + +## Commercial aspects + +A storage provider needs to get storage deals to grow his network power and to earn money. There are at least 2 ways to get storage deals, each one requiring specific sales skills. + +* Obtaining data replicas from other storage providers and programs: + + Filecoin data programs specify the minimum amount of replicas for a deal. Programs like Slingshot and platforms like Estuary require a minimum of 6 replicas per deal. This means deals need to be stored across multiple storage providers in the ecosystem, so you can work with peers in the network to share clients’ data replicas. + + Working in the ecosystem and building connections with other storage providers takes time and effort, and is essentially a sales activity. +* Onboarding your own customers: + +Acquiring your own customers, and bringing their data onto the Filecoin network, requires business development skills and people on your team who actively work with data owners (customers) to educate them about the advantages of decentralized storage. + +It takes additional effort to work with customers and their data, but it has the additional advantage of being able to charge your customer for the data being stored. This means an additional revenue stream compared to only storing copies of deals, and earning block rewards. diff --git a/storage-providers/skills/security.md b/storage-providers/skills/security.md new file mode 100644 index 000000000..f543a801e --- /dev/null +++ b/storage-providers/skills/security.md @@ -0,0 +1,43 @@ +--- +description: >- + This page covers the importance of security for Filecoin storage providers, + including the need to mitigate potential security threats and implement + appropriate security controls. +--- + +# Security + +Being a Filecoin storage provider involves more than just storing customer data. You are also responsible for managing Filecoin wallets and running systems that require 24/7 uptime to avoid losing collateral. This means that if your network or systems are compromised due to a security intrusion, you risk experiencing downtime or even losing access to your systems and storage. Therefore, maintaining proper security is of utmost importance. + +As a storage provider, you must have the necessary skills and expertise to identify and mitigate potential security threats.

One effective strategy is to implement a redundant firewall setup that can filter incoming traffic as well as traffic between your VLANs. + +A next-generation firewall (NGFW) can provide even more robust security by incorporating an intrusion prevention system (IPS) at the network perimeter. This can help to detect and prevent potential threats before they can do any harm. + +However, it is important to note that implementing a NGFW with IPS enabled can also have an impact on your internet bandwidth. This is because the IPS will inspect all incoming and outgoing traffic, which can slow down your network performance. As such, it is important to carefully consider your bandwidth requirements and plan accordingly. + +## System security + +A second layer of defense is system security. There are multiple concepts that contribute to good system security: + +* Host-based firewall (UFW) + + Implement a host-based firewall on your systems (also called UFW on Ubuntu), which is `iptables` based. +* SELinux + + Linux comes with an additional security implementation called `SELinux` (Security Enhanced Linux). Most system administrators will not implement this by default because it takes additional consideration and administration. Once activated though it offers the highest grade of process and user isolation possible on Linux and contributes greatly to better security. +* Not running as root + + It is a common mistake to run processes or containers as `root`. This is a serious security risk because any attacker who compromises a service running as root automatically obtains root privileges on that system. + + Lotus software does not require root privileges and therefore should run under a normal account (such as a service account, for instance called `lotus`) on the system. +* Privilege escalation + + Since it is not required that Lotus runs as root, it is also not required for the service account to have privilege escalation. This means you should not allow the `lotus` account to use `sudo`. diff --git a/storage-providers/skills/storage.md b/storage-providers/skills/storage.md new file mode 100644 index 000000000..c5ab00b53 --- /dev/null +++ b/storage-providers/skills/storage.md @@ -0,0 +1,55 @@ +--- +description: >- + This content covers various aspects related to storage in the context of being + a Filecoin storage provider. +--- + +# Storage + +Storage is a critical component of running a successful storage provider in the Filecoin network.

It is a popular choice among storage providers due to its reliability, scalability, and performance. + +Configuring ZFS requires knowledge and skills that go beyond the basics of traditional file systems. As a storage provider you need to understand how ZFS manages data, including how it distributes data across disks and how it handles data redundancy and data protection. You must also know how to configure ZFS for optimal performance and how to troubleshoot issues that may arise with ZFS. + +In addition to configuring ZFS, storage providers must also be able to manage the disks and other hardware used for storage. This includes selecting and purchasing appropriate hardware, installing and configuring disks and disk controllers, and monitoring disk health and performance. + +Having the knowledge and skills to configure ZFS is crucial as a storage providers, as it enables you to provide reliable and high-performance storage services to your clients.

One of the unique features of ZFS is its built-in support for various types of RAID configurations, which makes it an ideal choice for data storage in a Filecoin network. + +As a storage provider, it is crucial to have knowledge and skills in configuring ZFS. This includes understanding how to create virtual devices (VDEVs), which are the building blocks of ZFS storage pools. A VDEV can be thought of as a group of physical devices, such as hard disks, solid-state drives, or even virtual disks, that are used to store data. + +In addition, storage providers must also understand how wide VDEVs should ideally be, and how to create storage pools with a specific RAID protection level. RAID is a method of protecting data by distributing it across multiple disks in a way that allows for redundancy and fault tolerance. ZFS has its own types of RAID, known as RAID-Z, which come in different levels of protection. + +For example, `RAIDZ2` is a configuration that provides double parity, meaning that two disks can fail simultaneously without data loss. As a storage provider, it is important to understand how to create storage pools with the appropriate level of RAID protection to ensure data durability. + +Finally, creating datasets is another important aspect of ZFS configuration. Datasets are logical partitions within a ZFS storage pool that can have their own settings and attributes, such as compression, encryption, and quota. As a storage provider, it is necessary to understand how to create datasets to effectively manage storage and optimize performance. + +### Snapshots and replication + +ZFS provides built-in protection for data in the form of snapshots. Snapshots are read-only copies of a ZFS file system at a particular point in time. By taking regular snapshots, you can protect your data against accidental deletions, file corruption, or other disasters. + +To ensure that your data is fully protected, it is important to configure a snapshot rotation schema. This means defining a schedule for taking snapshots and retaining them for a specified period of time. For example, you might take hourly snapshots and retain them for 24 hours, and then take daily snapshots and retain them for a week. + +In addition to snapshots, ZFS also allows you to replicate them to another system running ZFS. This can be useful for creating backups or for replicating data to a remote site for disaster recovery purposes. ZFS replication works by sending incremental changes to the destination system, which ensures that only the changes are sent over the network, rather than the entire dataset. This can significantly reduce the amount of data that needs to be transferred and can help minimize network bandwidth usage. + +## Performance analysis + +As a storage provider, it is crucial to be able to troubleshoot and resolve any performance issues that may arise. This requires a deep understanding of the underlying storage system and the ability to use Linux performance analytic tools such as `iostat`. These tools can help identify potential bottlenecks in the storage system, such as high disk utilization or slow response times. + +In addition to troubleshooting, you must also be able to optimize the performance of your storage system. One way to improve performance is by implementing an NVMe write-cache. NVMe is a protocol designed specifically for solid-state drives, which can greatly improve the speed of write operations. By adding an NVMe write-cache to the storage system, you can reduce the latency of write operations and improve overall system performance. + +Read-cache on the other hand is typically not useful in the context of Filecoin. This is because sealed sectors are read very randomly, and unsealed sectors will typically not be read twice. Therefore, storing data in a read-cache would be redundant and add unnecessary overhead to the system. diff --git a/storage-providers/storage-providers.md b/storage-providers/storage-providers.md new file mode 100644 index 000000000..33e112a90 --- /dev/null +++ b/storage-providers/storage-providers.md @@ -0,0 +1,2 @@ +# Storage providers +
