I have a test Hyperledger Fabric environment using docker and caliper.
I have installed the fabric from https://github.com/hyperledger/fabric.
I want to reuse the started test network in fabcar folder, but using networkDown.sh to stop the network and start it again is very time consuming.
Is there a way to reset the fabric blockchain to its first state or genesis block without recreating it, so I can run a new Caliper test on it?
No, there is no supported way of resetting a channel on peers and orderers to genesis blocks. However, you may create a new channel if that helps.
