摘要: A new randomized Byzantine agreement algorithm is presented. This operates in a synchronous system of n processors, at most t which can fail. The reaches 0(t/log n) expected rounds and O(n2tf/log message bits independent the distribution processor failures. performance further improved to constant number O(n2) if failures assumed be uniform. In either event, improves on known lower bound for deterministic algorithms. Some other advantages are that it requires no cryptographic techniques, amount local computation small, random used per only one. It argued many practical applications agreement, this paper achieves superior performance.
