Warning

The following instructions have been written for and tested exclusively on Linux

A. Backend

  1. Install Docker & Docker Compose
  2. Install Fabric binaries and Docker images like so:
cd fabric
curl -sSLO https://raw.githubusercontent.com/hyperledger/fabric/main/scripts/install-fabric.sh
chmod +x install-fabric.sh
./install-fabric.sh

Important

Ensure the config directory is generated inside fabric

  1. Install Chaincode dependencies:
cd chaincode
npm install
  1. Start Fabric network:
cd ../network
./network.sh up createChannel -ca -c CHANNEL_NAME
./network.sh deployCC -c CHANNEL_NAME -ccn CHAINCODE_NAME -ccp /path/to/chaincode -ccl javascript

Note

Internet connection is required for chaincode deployment

After initial setup, you can use the following commands:

./network.sh up # Start network
./network.sh down # Reset everything -> Need to setup again
  1. Wallet Creation:
DIR=../../backend/connections
mkdir -p $DIR
cp organizations/peerOrganizations/org1.example.com/connection-org1.json $DIR/connection-org1.json
cp organizations/peerOrganizations/org2.example.com/connection-org2.json $DIR/connection-org2.json
cp organizations/peerOrganizations/org3.example.com/connection-org3.json $DIR/connection-org3.json
cp organizations/peerOrganizations/org4.example.com/connection-org4.json $DIR/connection-org4.json
cd ../../backend
mkdir -p wallet
node initWallet.js org1 ../fabric/network/organizations/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp ./wallet admin-org1
node initWallet.js org2 ../fabric/network/organizations/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp ./wallet admin-org2
node initWallet.js org3 ../fabric/network/organizations/peerOrganizations/org3.example.com/users/Admin@org3.example.com/msp ./wallet admin-org3
node initWallet.js org4 ../fabric/network/organizations/peerOrganizations/org4.example.com/users/Admin@org4.example.com/msp ./wallet admin-org4
  1. The .env file must be created in backend like so:
# Backend server
PORT=4000

# JWT
JWT_SECRET=some_secret
TOKEN_EXPIRES_IN=24h

# Fabric Connection
CHANNEL=CHANNEL_NAME
CHAINCODE=CHAINCODE_NAME
AS_LOCALHOST=true
WALLET_PATH="./wallet"

IDENTITY_ORG1="admin-org1"
CCP_PATH_ORG1="./connections/connection-org1.json"
IDENTITY_ORG2="admin-org2"
CCP_PATH_ORG2="./connections/connection-org2.json"
IDENTITY_ORG3="admin-org3"
CCP_PATH_ORG3="./connections/connection-org3.json"
IDENTITY_ORG4="admin-org4"
CCP_PATH_ORG4="./connections/connection-org4.json"

Note

Make sure the port is not blocked by a firewall

  1. Start backend:
npm install
npm run init
npm start

B. Frontend

To start the frontend ->

cd frontend
npm install

Then find your computer's IP address (using ifconfig) and execute the following:

echo 'export const API_BASE = "http://IP_ADDRESS:4000/api";' >> config.js
npm start
