   A financial institution is choosing between Raft and Kafka-based ordering for its Hyperledger Fabric network. The institution requires a simple, production-supported ordering service with minimal operational overhead. Which should they choose and why?

   • BRaft, because it is the recommended production ordering service with built-in crash fault tolerance and no external dependencies.
   • CRaft, because it provides Byzantine fault tolerance.
   • DKafka, because it is simpler to configure than Raft.
