What happens in Hyperledger Fabric on a private channel block-chain consisting of only two peers if one of the peers is faulty and manipulates it's private block chain?
So the two copies of the block chain will diverge and finally it will be impossible for a consensus algorithm to tell which one is correct.
Is this a valid problem? If so, how would this be mitigated? Would it help to add additional peers to the channel (e.g. placed at a regulator's data center) which are not in control of the two peers mentioned above? Or is there a better solution to tackle this problem?
