Web“Fischer, Lynch, Paterson (FLP)” result that asserts impos-sibility of reaching consensus in a distributed system, in the presence of failures. I will explain what it says, why it is true, and what its signiﬁcance has been. Because distributed algorithms must contend with many subtleties that do not arise in simpler settings, modeling WebFischer, Lynch, and Paterson showed that there is no protocol that solves consensus in any asynchronous message‐passing system where even a single process can fail. This result is one of the most influential results in Distributed Computing, laying the foundations for a number of subsequent research efforts. Terminology
