Consensus-based replication in HBase

Konstantin Boudnik (WANdisco):

The idea behind consensus-based replication is pretty simple: instead of trying to guarantee that all replicas of a node in the system are synced post-factum to an operation, such a system will coordinate the intent of an operation. If a consensus on the feasibility of an operation is reached, it will be applied by each node independently. If consensus is not reached, the operation simply won’t happen. That’s pretty much the whole philosophy.

Not enough details, but doesn’t this sound like Paxos applied earlier?
