WebApr 10, 2024 · Home Archive Fischer-Lynch-Paterson Impossibility Result Updated on 2024-04-10 The paper proves that any consensus protocol that tolerates one process failure under the reliable (completely) asynchronous message system, in which all messages are eventually delivered with arbitrary delay and out of order, fails to reach consensus when … WebThe FLP impossibility result. I will only briefly summarize the FLP impossibility result, though it is considered to be more important in academic circles. The FLP impossibility result (named after the authors, Fischer, Lynch and Patterson) examines the consensus problem under the asynchronous system model (technically, the agreement problem ...
How Does Distributed Consensus Work? by Preethi Kasireddy

CS5412: CONSENSUS AND THE FLP IMPOSSIBILITY …
WebNov 13, 2024 · Nonetheless, scientists continued to push forward to find ways to circumvent FLP impossibility. At a high level, there are two ways to circumvent FLP impossibility: Use synchrony assumptions. This result is sometimes called the FLP impossibility proof named after the authors Michael J. Fischer, Nancy Lynch, and Mike Paterson who were awarded a Dijkstra Prize for this significant work. The FLP result has been mechanically verified to hold even under fairness assumptions. See more A fundamental problem in distributed computing and multi-agent systems is to achieve overall system reliability in the presence of a number of faulty processes.

Some of the processes (agents) may fail or be unreliable in other … See more Varying models of computation may define a "consensus problem". Some models may deal with fully connected graphs, while others may deal with rings and trees. In some models message authentication is allowed, whereas in others processes are completely … See more To solve the consensus problem in a shared-memory system, concurrent objects must be introduced.
