Network configuration: bclan

Initial configuration

Cryptography

cryptogen generate --config=./crypto-config.yaml

Artefacts

export FABRIC_CFG_PATH=$PWD

Orderers

  • Orderer genesis block
configtxgen -profile BlockchainLANOrdererGenesis -outputBlock ./config/genesis.block

Channels

export CHANNEL=sandbox
  • Channel configuration transaction
configtxgen -profile BlockchainLANCoopChannels -outputCreateChannelTx ./config/${CHANNEL}.tx -channelID $CHANNEL
  • Anchor peer transaction
configtxgen -profile BlockchainLANCoopChannels -outputAnchorPeersUpdate ./config/BlockchainLANCoopMSPanchors.tx -channelID $CHANNEL -asOrg BlockchainLANCoop

Network setup

Docker containers environment

export ORGA=bc-coop.bclan

echo COMPOSE_PROJECT_NAME="bclan" > .env
echo ca__CA_KEYFILE=$(basename $(ls crypto-config/peerOrganizations/${ORGA}/ca/*_sk)) >> .env
echo ca__TLS_KEYFILE=$(basename $(ls crypto-config/peerOrganizations/${ORGA}/tlsca/*_sk)) >> .env
echo ca__ADMIN=$(cat /dev/urandom | xxd | head -n 1 | cut -b 10-49 | sed "s/ //g") >> .env
echo ca__PASSWD=$(cat /dev/urandom | xxd | head -n 1 | cut -b 10-49 | sed "s/ //g") >> .env
echo explorerdb__ADMIN=$(cat /dev/urandom | xxd | head -n 1 | cut -b 10-49 | sed "s/ //g") >> .env
echo explorerdb__PASSWD=$(cat /dev/urandom | xxd | head -n 1 | cut -b 10-49 | sed "s/ //g") >> .env

echo cli_ORGA=${ORGA} >> .env
echo cli_USER=Admin >> .env

Start network

docker-compose -f docker-compose.yaml up -d ca.bc-coop.bclan orderer.bclan peer0.bc-coop.bclan cli.bc-coop.bclan

Use the CLI container environment

  • Runtime CLI configuration
cli_ORGA=bc-coop.bclan
echo cli_ORGA=${cli_ORGA} > util/env

# orderer address and certificate
echo ORDERER_ADDR="orderer.bclan:7050" >> util/env
echo ORDERER_CERT="/etc/hyperledger/orderer/tlsca.bclan-cert.pem" >> util/env

# current session chaincode
echo CHANNEL="sandbox" >> util/env
echo CHAINCODE="ex02" >> util/env

# override target peer if needed
echo CORE_PEER_ADDRESS="peer0.${cli_ORGA}:7051" >> util/env

# Enter CLI environment
docker exec -it cli-bclan /bin/bash

# Channel creation in CLI environment
source /opt/blockchain-coop/env
peer channel create -o ${ORDERER_ADDR} -c ${CHANNEL} -f /etc/hyperledger/config/${CHANNEL}.tx --tls --cafile ${ORDERER_CERT}
peer channel join -b ${CHANNEL}.block

Use ssm

  • Install chaincode
# Chaincode intantiation in CLI environment
source /opt/blockchain-coop/env
peer chaincode install /opt/civis-blockchain/ssm/ssm.pak
  • Instantiate with admin "adam"
source /opt/blockchain-coop/env
source /opt/civis-blockchain/ssm/env

# Create keys for "adam"
rsa_keygen adam
# Create init.arg string
echo -n '{"Args":["init","[' > init.arg
json_agent adam adam.pub | jq . -cM | sed 's/"/\\"/g' | tr -d "\n" >> init.arg
echo -n ']"]}' >> init.arg
# Init chaincode
peer chaincode instantiate -o ${ORDERER_ADDR} --tls --cafile ${ORDERER_CERT} -C ${CHANNEL} -n ${CHAINCODE} -v ${VERSION} -c $(cat init.arg) -P "OR ('BlockchainLANCoopMSP.member')"

peer chaincode query -C ${CHANNEL} -n ${CHAINCODE} -c '{"Args":["admin", "adam"]}'

exit

Use chaincode_example02

# Chaincode intantiation in CLI environment
source /opt/blockchain-coop/env
peer chaincode install -n ${CHAINCODE} -v 1.0 -p blockchain-coop/go/chaincode_example02/
peer chaincode instantiate -o ${ORDERER_ADDR} --tls --cafile ${ORDERER_CERT} -C ${CHANNEL} -n ${CHAINCODE} -v 1.0 -c '{"Args":["init","a", "100", "b","200"]}' -P "OR ('BlockchainLANCoopMSP.member')"

# Chaincode usage in CLI environment
source /opt/blockchain-coop/env
peer chaincode query -C ${CHANNEL} -n ${CHAINCODE} -c '{"Args":["query","a"]}'
peer chaincode invoke -o ${ORDERER_ADDR} -C ${CHANNEL} -n ${CHAINCODE} --tls --cafile ${ORDERER_CERT} -c '{"Args":["invoke","a","b","10"]}'
peer chaincode query -C ${CHANNEL} -n ${CHAINCODE} -c '{"Args":["query","b"]}'

exit

Start hyperledger explorer

docker-compose -f docker-compose.yaml up -d explorerdb.bc-coop.bclan explorer.bc-coop.bclan

Use the node.js SDK

npm install ../sdk/node/
export PATH=$(pwd)/node_modules/blockchain-coop:$PATH
source .env
  • Enroll the bclan admin
bcc-cli.js enroll $ca__ADMIN $ca__PASSWD bclan
bcc-cli.js check $ca__ADMIN
bcc-cli.js query $ca__ADMIN peer0 bclan sandbox ex02 query a
bcc-cli.js invoke $ca__ADMIN peer0:bclan sandbox ex02 invoke a b 1
bcc-cli.js query $ca__ADMIN peer0 bclan sandbox ex02 query a
  • Register and enroll a new user
bcc-cli.js register $ca__ADMIN $ca__PASSWD bclan Fred ABCD1234
bcc-cli.js enroll Fred ABCD1234 bclan
bcc-cli.js check Fred
bcc-cli.js query Fred peer0 bclan sandbox ex02 query b
bcc-cli.js invoke Fred peer0:bclan sandbox ex02 invoke a b 50
bcc-cli.js query Fred peer0 bclan sandbox ex02 query b

Stop network and cleanup

docker-compose -f docker-compose.yaml down

git clean -fdx
