Likewise, there are different … WebLamport's Byzantine Generals Algorithm. I've stumbled at the first OralMessage algorithm in Lamport, et al's paper. I've searched the web and there are dozens of sites, restating in exactly the same terms and examples, which isn't helping me. Lamport claims the algorithm can handle (n-1)/3 traitors, and works when the commander is a traitor.
