IQUERY project is an off-chain query layer for blockchain network in Hyperledger Fabric 1.4 or Geth v1.10.23 (popular Go implementation of Ethereum) . We offer the block listener in blocklistener directory . We offer the benchmark script for baseline in baseline directory . We offer the script in experiment directory .
The chaincode for payment network is in contract directory
IQUERY applies a block listener to receive blocks from a Fabric peer node with a valid certificate. Then IQUERY employs a Merkle Bucket Tree based multi-origin query to enable tamper evident query results from different organization domains. CouchDB supports Map-Reduce functions for conditional and temporal queries.
1.Start the distributed Fabric network：we have a cluster of IP 226,227,228,229,230
The network configuration is in baseline directory
230
cd /home/ubuntu/local-user-name/fabric-v1.4/2org1peercouchdb
docker-compose -f org1-230-couch.yaml up -d
229
cd /home/ubuntu/local-user-name/fabric-v1.4/2org1peercouchdb
docker-compose -f org1-229-1.4.0.yaml up -d
228
cd /home/ubuntu/local-user-name/fabric-v1.4/2org1peercouchdb
docker-compose -f org2-228-1.4.0.yaml up -d
227
cd /home/ubuntu/local-user-name
docker-compose -f org2-227-couch.yaml up -d
226
cd /home/local-user-name/caliper/packages/caliper-samples/network/fabric-v1.4/2org1peercouchdb
docker-compose -f ca-orderer.yaml up -d
2.Create mychannel:
229
docker exec -e "CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/[email protected]/msp" peer0.org1.example.com peer channel create -o orderer.example.com:7050 -c mychannel -f /etc/hyperledger/configtx/mychannel.tx
docker exec -e "CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/[email protected]/msp" peer0.org1.example.com peer channel fetch config -o orderer.example.com:7050 -c mychannel mychannel.block
docker exec -e "CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/[email protected]/msp" peer0.org1.example.com peer channel join -b mychannel.block
228
docker exec -e "CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/[email protected]/msp" peer0.org2.example.com peer channel fetch config -o orderer.example.com:7050 -c mychannel mychannel.block
docker exec -e "CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/[email protected]/msp" peer0.org2.example.com peer channel join -b mychannel.block
