This document discusses configuring a multi-node Hyperledger Fabric network. It shows the process of configuring two nodes (node1 and node2) to join the network, install and instantiate a chaincode, and perform queries. Scripts are provided to handle channel creation, joining peers to the channel, and installing/querying the chaincode on each node.

6. node1 – 스크립트 (계속)
6
• 채널 생성
- peer channel create -o orderer.example.com:7050 -c $CHANNEL_NAME -f
${CHANNEL_NAME}.tx --tls --cafile $ORDERER_CA
• 채널 조인
- peer channel join -b ./${CHANNEL_NAME}.block
• Anchor Peer 업데이트
- peer channel update -o orderer.example.com:7050 -c $CHANNEL_NAME -
f ./${CORE_PEER_LOCALMSPID}anchors.tx --tls --cafile $ORDERER_CA

7. node1 - 스크립트
7
• 체인코드 설치
- peer chaincode install -n mycc -v ${VERSION} -l ${LANGUAGE} -p
${CC_SRC_PATH}
• 체인코드 Instantiate
- peer chaincode instantiate -o orderer.example.com:7050 -C
$CHANNEL_NAME -n mycc -l ${LANGUAGE} -v ${VERSION} -c
'{"Args":["init","a","100","b","200"]}' -P "OR
('Org1MSP.peer','Org2MSP.peer')" --tls --cafile $ORDERER_CA
• 체인코드 Query
- peer chaincode query -C $CHANNEL_NAME -n mycc -c
'{"Args":["query","a"]}'

8. node2 – 스크립트 (계속)
8
• Genesis Block Fetch
- peer channel fetch 0 ${CHANNEL_NAME}.block -o
orderer.example.com:7050 -c $CHANNEL_NAME --tls --cafile $ORDERER_CA
• 채널 조인
- peer channel join -b ./${CHANNEL_NAME}.block
• Anchor Peer 업데이트
- peer channel update -o orderer.example.com:7050 -c $CHANNEL_NAME -
f ./${CORE_PEER_LOCALMSPID}anchors.tx --tls --cafile $ORDERER_CA

9. node2 - 스크립트
9
• 체인코드 설치
- peer chaincode install -n mycc -v ${VERSION} -l ${LANGUAGE} -p
${CC_SRC_PATH}
• 체인코드 Query
- peer chaincode query -C $CHANNEL_NAME -n mycc -c
'{"Args":["query","a"]}'

10. Invoke, Query 실습
10
• Invoke
- peer chaincode invoke -o orderer.example.com:7050 --tls --cafile
$ORDERER_CA -C $CHANNEL_NAME -n mycc -c
'{"Args":["invoke","a","b","10"]}’
• Query
- peer chaincode query -C $CHANNEL_NAME -n mycc -c
'{"Args":["query","a"]}'
