WebFeb 22, 2005 · Byzantine Agreement (BA) is a paradigm problem that attempts to isolate the key features of reaching agreement. We focus here on the number of messages required to reach BA, with particular emphasis on the number of messages required in the failure-free runs, since these are the ones that occur most often in practice.

WebThe Byzantine agreement problem is to devise an algorithm so that nprocessors, each with a private input can agree on a single common output that is equal to some processor’s input. For example, if all processors start with 1, they must all decide on 1. The processors should successfully terminate despite the presence of t= ( n) bad processors. WebRandomized algorithms for Byzantine agreement with re-silience t = ( n) and constant expected time have been known for 25 years, under the assumption of private channels (so that the adversary cannot see messages passed between processors) [13]. Under these assumptions, more recent work shows that optimal resilience can be achieved [11].
