Hello everybody, i want change orderer from solo to raft. I can switch off the network but i want to mantain data in the ledger after restart with new orderer. It's possible? I haven't found

Abhijeet, Certificate Authorities --- specifically, the Fabric CA --- should be used to create all of the certificates in a production scenario (it is a best practice tp stand up one CA for each

Hi, I believe I resolved the issue. Within my chaincode folder, I had files example-chaincode.js, example-chaincode.go and a compiled go chaincode named example-chaincode. After removing

Hi Suresh, Check this one: https://github.com/APGGroeiFabriek/PIVT It's the most convenient way of running Fabric in Kube as of now. Best, Hakan
