Ben-Or’s algorithm reduces Byzantine agreement to the problem of generating a mutually agreed upon coinflip. In this sense it is similar to Rabin’s global coinflip algorithm [10], which however assumes the existence of a global coin.

The consensus problem requires agreement among a number of processes (or agents) for a single data value. Some of the processes (agents) may fail or be unreliable in other ways, so consensus protocols must be fault tolerant or resilient. The processes must somehow put forth their candidate values, communicate with one …

Webthe protocols in [19] are round-optimal. In particular, we show that we require at least 3 rounds for a (3,1)-SVSS protocol, and can extend this to 4 rounds if t > 1,n ≤ 3t − 1. We also show that a weaker notion of Byzantine Agreement, where non-dealer players are allowed to broadcast is impossible for n ≤ 3t, for any number of rounds.
