Hi Jorn, I was talking with the context of Hyperledger Fabric Blockchain where the cluster of kafka zookeeper is used where there might be multiple orgs taking part in the network and transactions where a single system getting failed or a malicious node might disrupt the whole network which would cost a lot. So on that aspect I was asking if its possible to have a pluggable algorithm for zookeeper ?

It is surprising to me that you have them and it is unlikely that you have them due to a specific consensus algorithm. If you have stability issues then I would look at your architecture for weak spots. Btw. Paxos is a consensus mechanism. Bft just describes a specific type of failures in distributed systems, so implement BFT does probably not make sense. > Am 27.08.2019 um 06:36 schrieb Nayak, Soumya R. <sna...@firstam.com>: > > Hi Team, > > Currently Zookeeper and Kafka cluster are Crash Fault Tolerant. > Zookeeper uses a version of Paxos - Zookeeper atomic broadcast.
