Byzantizing Paxos by Refinement

  • Leslie Lamport
Part of the Lecture Notes in Computer Science book series (LNCS, volume 6950)


We derive a \(3f\!+\!1\) process Byzantine Paxos consensus algorithm by Byzantizing a variant of the ordinary Paxos algorithm—that is, by having \(2f\!+\!1\) nonfaulty processes emulate the ordinary Paxos algorithm despite the presence of f malicious processes. We have written a formal, machine-checked proof that the Byzantized algorithm implements the ordinary Paxos consensus algorithm under a suitable refinement mapping.
