Impossibility of Distributed Consensus with One Faulty Process. Journal Article April 1, 1984 - September 30, 1985

摘要

The consensus problem involves an asynchronous system of processes, some of which may be unreliable. The problem is for the reliable processes to agree on a binary value. In this reprint, it is shown that every protocol for this problem has the possibility of nontermination, even with only one faulty process. By way of contrast, solutions are known for the synchronous case, 'Byzantine Generals' problem.
