Hi All, I have blockchain network consisting of two ORGs, each ORG having only single peer. And I have simple chaincode with several functions. One function that I'm invoking has two operations: read

Hi, I‘m looking for an example how to setup TLS for the shim.chaincode server. I would like to know how I can setup an example with TLS enabled.

Thank you for your answer! I used your javaenv image. I try the "Write your FIrst Application" tutorial for java and when I run the app after building dependencies: (mvn test for fabcar application an

As Gari pointed out, the reason for the failing build is that protoc-gen does not have a native binary for arm64. With no promises it'll work here is an image you can try: btl5037/fabric-javaenv:2.2.0

#fabric-chaincode

Does anyone have the image fabric-javaenv for version 2.2.0 for arm architecture to send me? Thanks in advance.

#fabric-chaincode

The issue is that a prebuilt binary for protoc-gen-grpc-java is NOT available for the Arm architecture ( https://repo.maven.apache.org/maven2/io/grpc/protoc-gen-grpc-java/1.23.0/ ). You will need to b

Hello - that really does look like it's still trying to use GO rather than Java Chaincode. I would suggest at you look at the Fabric-Samples github repo or the IBM Blockchain VSExtension tutorials...

I've a query on how we need to deal with data structure changes in chaincode. Lets say, you have deployed the chaincode in production and lot of data stored in ledger and world state db(Couchdb). If y
