TL;DR; Go to ---- EDIT section below I am using hfc@0.6.5 in a standalone node.js application. A membersrvc and peer are started with docker-compose , where: membersrvc: container_name: membersrvc image: hyperledger/fabric-membersrvc:latest ports: - "7054:7054" command: membersrvc vp0: container_name: peer image: hyperledger/fabric-peer:latest ports: - "7050:7050" - "7051:7051" - "7053:7053" environment: - CORE_PEER_ADDRESSAUTODETECT=true - CORE_VM_ENDPOINT=unix:///var/run/docker.sock - CORE_LOGGING_LEVEL=DEBUG - CORE_PEER_ID=vp0 - CORE_SECURITY_ENABLED=true - CORE_PEER_PKI_ECA_PADDR=172.17.0

Is there any way to get the history for Private data in Hyperledger Fabric node SDK. I've tried using getHistoryForKey(key) It returns an empty object with only { done: true } The API to get history for private data is not yet implemented, but is planned for a future release of Hyperledger Fabric. In the interim you could add some minimal information to a public key in the same transaction for historical tracking. That could either be a logical key, or if the key itself is sensitive, you could take a hash of the logical key and save that as a public key. Then use GetHistoryForKey on the public

I'm trying to make the tutorial " Chaincode for Developers " work. But at the section " Terminal 3 - Use the chaincode " I'm stuck trying to run this command $ peer chaincode instantiate -n mycc -v 0 -c '{"Args":["a","10"]}' -C myc It exits with this error : Error: Error endorsing chaincode: rpc error: code = Unknown desc = Failed to init chaincode(handler not found for chaincode mycc:0) I've done some research but I don't know what to do. Could somebody please help me ? This is solved. There were three primary problems. As Chris mentioned, the certs are expired. In the future you can easily

I tried to compile chaincode sample and write my own one ( https://github.com/hyperledger/fabric/tree/master/examples/chaincode/java/SimpleSample ) However, I can't get a shim-client-1.0. Do you have plans to make java sdk public? I hope that “shim-client-1.0.jar” will be added to maven repository soon, nevertheless you can try to compile it using source code in “github.com/hyperledger/fabric/core/chaincode/shim/java”. gradle build and "shim-client-1.0.jar" will be available in github.com/hyperledger/fabric/core/chaincode/shim/java/build/lib folder. 来源： https://stackoverflow.com/questions

I want to see logs while calling functions in my chaincode, for debugging purposes. I tried something like this: var logger = shim.NewLogger("chaincode_example02") logger.Info("get_caller_data called"); I've viewed logs of the peer running the chaincode, but I couldn't find the above log. What am I doing wrong? If you startup your chaincode in dev mode using a command like ./chaincode_example02 , then the log statements should be visible in the console where that same process is started. If you deploy the chaincode in net mode then each peer starts up a docker container that is named something

I am following the below link to run the first network sample using the custom crypto graphic material. First Network with custom cryptographic material Post generation of certificates from the Third Party CA. i have places all the certificates in the required dir structure. Following other steps now when i start the docker containers they come up. but when i try to create channell i get below error Error: got unexpected status: BAD_REQUEST -- Error authorizing update: Error validating DeltaSet: Policy for [Groups] /Channel/Application not satisfied: Failed to reach implicit threshold of 1 sub
