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. WebConsider the Byzantine agreement problem presented in "reaching agreement in the presence of faults". Let's assume the same model except that if process i is non-faulty, V …

Presentation By: Shahar Yair 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 ...
