WebJan 1, 1994 · Faulty processes mayattempt to inhibit agreement by acting in a malicious or "Byzantine" manner. Approximate agreement defines one form of agreement in which the voted values obtained by the non-faulty processes need not be identical.

WebStabilizing consensus requires non-faulty nodes to eventually agree on one of their inputs, but individual nodes do not necessarily know when agreement is reached. First we show that, similar to the original consensus problem in the synchronous model, there exist deterministic solutions to the stabilizing consensus problem tolerating crash faults. WebAlgorithms are presented to reach approximate agreement in aynchronous, as well as synchornous systems. The asynchronous agreement algorithm is an interesting contrast to a result of Fischer, Lynch, and Paterson, who show that exact agreement is not attainable in an asychronous system with as few as one fault process. The algorithms work by ...
