WebByzantine fault tolerance can be achieved if the loyal (non-faulty) generals have a majority agreement on their strategy. There can be a default vote value given to missing messages. For example, missing messages can be given a "null" value. Further, if the agreement is that the null votes are in the majority, a pre-assigned default strategy ...

WebByzantine Clock Synchronization Leslie Lamport 1 P. M. Melliar-Smith 2 Computer Science Laboratory SRI International Abstract An informal description is given of three fault-tolerant clock-synchronization algorithms. These algorithms work in the presence of arbitrary kinds of failure, including "two- faced" clocks. WebLamport’s Paxos protocol [12] and Castro and Liskov’s work on Practical Byzantine Fault-tolerance (PBFT pro-tocol) [3]. In addition, the techniques we use to reduce the number of communication steps are inspired by the work on Byzantine quorum systems pioneered by Malkhi and Reiter [17]. The two earlier protocols that are closest to FaB
