  • Generates identity JSON files

3. Deploy Full Production System

Follow the complete deployment guide:

# 1. Start IPFS
cd ipfs
.\ipfs.ps1 start

# 2. Generate certificates
cd ..\fabric-network
cryptogen generate --config=crypto-config.yaml

# 3. Generate genesis block
configtxgen -profile ThreeOrgsOrdererGenesis -outputBlock ./channel-artifacts/genesis.block

# 4. Start Fabric network
.\network.ps1 up

# 5. Enroll users with Fabric CA
