A modular framework for building EVM consensus clients ⛵️✨

What is BeaconKit?

BeaconKit is a modular framework for building EVM based consensus clients. The framework offers the most user-friendly way to build and operate an EVM blockchain, while ensuring a functionally identical execution environment to that of the Ethereum Mainnet.

Supported Execution Clients

Through utilizing the Ethereum Engine API BeaconKit is able to support all 6 major Ethereum execution clients:

• Geth: Official Go implementation of the Ethereum protocol.
• Erigon: More performant, feature-rich client forked from go-ethereum.
• Nethermind: .NET based client with full support for Ethereum protocols.
• Besu: Enterprise-grade client, Apache 2.0 licensed, written in Java.
• Reth: Rust-based client focusing on performance and reliability.
• Ethereumjs: Javascript based client managed by the Ethereum Foundation.

Running a Local Development Network

Prerequisites:

• Docker
• Golang 1.23.0+
• Foundry

Start by opening two terminals side-by-side:

Terminal 1:

# Start the sample BeaconKit Consensus Client:
make start

Terminal 2:

Note: This must be run after the beacond node is started since make start will populate the eth-genesis file used by the Execution Client.

# Start an Ethereum Execution Client:
make start-reth # or start-geth start-besu start-erigon start-nethermind start-ethereumjs
