BFTlike
BFTlike is a term used in distributed systems and blockchain literature to describe designs, protocols, or systems that resemble Byzantine fault-tolerant (BFT) consensus but do not necessarily adhere to its formal definitions or guarantees. The term is often used to discuss practical implementations that adopt BFT-inspired ideas such as replicated state machines, leader-based rounds, and quorum-based agreement, while relaxing some assumptions or accepting different fault models or synchrony conditions.
Characteristics of BFTlike protocols typically include cryptographic signatures, round-based voting, and mechanisms for progress in the
Differences from strict BFT lie in the guarantees provided. While true BFT protocols aim to guarantee safety
Applications and examples: BFTlike concepts appear in blockchain consensus discussions and other distributed systems where designers
Limitations: The term is informal; interpretations of what counts as BFTlike vary. Formal fault-tolerance guarantees depend
