Work Life Cycle

Generate

• Gen: Crypto certificates, Genesis block, Transaction-Channel, Transaction-Anchor Peer

$ cryptogen generate --config=./crypto-config.yaml                                                                                              # generate crypto certificates

$ configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org1MSPanchors.tx -channelID mychannel -asOrg Org1MSP        # generate transaction: anchor peer

Channel

Creating channel..

$ peer channel create -o orderer.example.com:7050 -c mychannel -f ./channel-artifacts/channel.tx --tls true --cafile $CA_FILE

Joining the channel...
$ peer channel join -b mychannel.block

Updating anchor peers for org1...
$ peer channel update -o orderer.example.com:7050 -c mychannel -f ./channel-artifacts/Org1MSPanchors.tx --tls true --cafile $CA_FILE

Chaincode

Installing chaincode on peer0.org1...
$ peer chaincode install -n mycc -v 1.0 -l golang -p github.com/chaincode/chaincode_example02/go/

Instantiating chaincode on peer0.org2...
CA_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
