WebBecause of this, several impossibility results have been derived—see for instance the well-known paper (Fischer, Lynch, & Paterson, 1985). As a consequence of these pessimistic results, many researchers have devoted their time and abilities to understanding how to reformulate the concept of system model in a fine-grained alternative way ... 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
