August undefined, 2024

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]. Webuse of techniques developed in studying Byzantine Agreement, is Approximate Agreement, introduced in [DLPSW]. In that paper algorithms were given for both synchronous and …

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.
