Byzantine fault tolerance can be achieved if the loyal (non-faulty) generals have a majority agreement on their strategy. There can be a default vote value given to missing messages. For example, missing messages can be given a "null" value . See more A Byzantine fault (also Byzantine generals problem, interactive consistency, source congruency, error avalanche, Byzantine agreement problem, and Byzantine failure ) is a condition of a computer system, particularly See more As an analogy of the fault's simplest form, consider a number of generals who are attacking a fortress.

WebThe Paxos algorithm [6] has become a standard tool for implementing fault-tolerant distributed systems. It uses 2f +1 processes to tolerate the benign failure of any f of them. More recently, Castro and Liskov developed a 3f + 1 process algorithm [2] that tolerates f Byzantine (maliciously faulty) processes. WebByzantine Fault Tolerance (BFT) is a consensus protocol that is not only able to tolerate failures in the computing systems on the network, it is also able to withstand corrupted data and malicious attacks. ...
