Attacks where adversaries have full control of a number of . authenticated devices and behave arbitrarily to disrupt the . network are referred to as Byzantine attacks [3].Once the active. set of insider nodes in the network are turned to be malicious by. the attackers then the whole network will be under the control.

Byzantine fault tolerance is 50% assuming zero network latency. It is around 46% (Ethereum) and 49.5% (Bitcoin) fault tolerant under actually observed conditions, but it goes down to 33% if network latency is equal to the block time and reduces to zero as network latency approaches infinity.24 Oca 2020

The Byzantine Generals Problem describes the difficulty decentralized systems have in agreeing on a single truth . The Byzantine Generals Problem plagued money for millennia, until the invention of Bitcoin. Bitcoin uses a Proof-of-Work mechanism and a blockchain to solve the Byzantine Generals Problem.

The Byzantine Agreement protocol is a protocol in distributed computing . It takes its name from a problem formulated by Lamport, Shostak and Pease in 1982, which itself is a reference to a historical problem.
