Does the FLP theorem say aBFT consensus is impossible?
WebSep 14, 2013 · 4. Purpose/Goals • CAP Theorem is at the base of developing distributed systems • Still - not everyone aware of it. • We want to (goals) o introduce it (theorem) o understand what it means to us as developers (implications and criticism) o learn (CAP in practice): of what others are doing what can be done. 5. In a fully asynchronous message-passing distributed system, in which at least one process may have a crash failure, it has been proven in the famous 1985 FLP impossibility result by Fischer, Lynch and Paterson that a deterministic algorithm for achieving consensus is impossible. [5] 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. This often requires coordinating processes to reach … See more Three agreement problems of interest are as follows. Terminating Reliable Broadcast A collection of $${\displaystyle n}$$ processes, numbered from $${\displaystyle 0}$$ to $${\displaystyle n-1,}$$ communicate by … See more To solve the consensus problem in a shared-memory system, concurrent objects must be introduced. A concurrent object, or shared object, is a data structure which helps concurrent processes communicate to reach an agreement. Traditional … See more The consensus problem requires agreement among a number of processes (or agents) for a single data value. 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 The Paxos consensus algorithm by Leslie Lamport, and variants of it such as Raft, are used pervasively in widely deployed distributed See more • Uniform consensus • Quantum Byzantine agreement • Byzantine fault tolerance See more raymond chaseling
