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...

Hi Bozhidar, Can you share the commands/output from when you packaged the chaincode? You may also find it helpful if you have not already done so, to review the tutorial “Deploying a Smart Contract to

Hello All, The peer has joined the channel and chaincode is packed on. I have a problem with instantiating chaincode in Hyperledger fabric Network version 2: # peer lifecycle chaincode install chainco

The second version of the chaincode would have to support both the old and new data. There are various approaches possible: You could attempt to unmarshal the JSON using new data structure, and if it

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

Hi Team, for the chaincode instantiation we pull the images dynamically from the docker hub. However, let's say if I have chaincode related images (e.g. fabric-ccenv, fabric-baseos, etc.) on a private

Hello Marek; Just to check I understand your situation. You're submitting a single transaction, that in effect, does a number of 'putState' calls. When that number gets to the ~140 the end-end time ha
