Byzantine Agreement: Difference between revisions

* Agreement problems are also studied in weaker failure models such as crash-failures.
* Agreement problems are also studied in weaker failure models such as crash-failures.
* Byzantine agreement is equivalent to the closely related problems of Byzantine Generals (in which only one player gets an input bit, which must be correctly communicated to all non-faulty players) and Interactive Consistency (in which all non-faulty players must correctly know the received input bit of each non-faulty player).

* It is known that no unconditionally secure classical protocol can solve Byzantine Agreement if the number of failures <math> t > n/3</math>.
