问题 I am on CentOS 7, installed all prerequisites, cloned the fabric-samples git repository. I am referring to the tutorial "Building Your First Network", found here. At this point I have successfully run the command ./byfn.sh generate Now I want to execute the Java chaincode, so I run ./byfn.sh up -l java Right after the START sign, I see the following output: Build your first network (BYFN) end-to-end test + peer channel create -o orderer.example.com:7050 -c mychannel -f ./channel-artifacts

问题 This is a continuation of my question found here. It seems like the nature of the error has changed hence I am asking a new question. A kind soul pointed out that the Java version mismatch in my previous run, so I ran docker container ls -a : CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 4bb779ce6b71 hyperledger/fabric-javaenv:2.0 "/bin/sh -c ./build.…" 2 minutes ago Up 2 minutes fervent_pare d23e83c3cde5 hyperledger/fabric-javaenv:2.0 "/bin/sh -c ./build.…" 2 days ago Exited (0) 2

问题 With consideration of existing functionality, developer productivity (assuming minimal experience in each language), support within the Fabric community, and roadmap for enhancements, is there any chaincode development language that should be preferred as the short-term and, perhaps separately, as the long-term choice? Prior question Node.js or Go for Hyperledger Fabric's chaincode development? did not address Java as an option, and does not account for recent Fabric 1.4 platform release. 回答1

问题 I am trying to get the operation which is responsible for the new state. In simple words, I want to get the function name passed to the invoke method. When I am looking into the historical states I am able to fetch its value, timestamp, transaction ID, etc. but not the parameters which are responsible for that transaction. I know we can get the parameters from the block history, but I need it for the states. Is there any way to achieve this from the chaincode side? 回答1: Yes, from the

问题 Is it possible to dynamically set access to private data in Hyperledger fabric 1.4? Unlike the collections file where we have to add the organizations that can have access to a particular "collection", is it possible to add access through chaincode? 回答1: Had to do some research on this myself, but since Fabric v1.4 it is possible to dynamically add peers to private data collections. Private data reconciliation ensures that all private data state in that collection, which was created prior to
