We investigate the reduction of atomic broadcast to consensus in systems with Byzantine faults. Among the several definitions of Byzantine consensus that differ only by their validity property, we identify those equivalent to atomic broadcast. Finally, we give the first deterministic atomic broadcast reduction with a constant time complexity with respect to consensus.
