Abstract
Existing Byzantine-resilient replication protocols satisfy
two standard correctness criteria, safety and liveness, in the
presence of Byzantine faults. In practice, however, faulty
processors can, in some protocols, significantly degrade
performance by causing the system to make progress at
an extremely slow rate. While "correct" in the traditional
sense, systems vulnerable to such performance degradation
are of limited practical use in adversarial environments.
