Flp theorem
WebUniversity of Texas at Austin WebJul 15, 2024 · The celebrated FLP theorem says that any protocol that solves Agreement in the asynchronous model that is resilient to at least one crash failure must have a non-terminating execution. This means that deterministic asynchronous consensus is impossible , but with randomization, asynchronous consensus is possible in constant expected time.
