Definition ∞ A BFT Consensus Model is a system that allows distributed computer networks to agree on a single state even if some participants behave maliciously. This Byzantine Fault Tolerance approach ensures network integrity and transaction finality by tolerating a certain proportion of faulty or dishonest nodes. Participants exchange messages and vote on proposed blocks, reaching agreement when a supermajority confirms the state. It is commonly utilized in various blockchain and distributed ledger technologies to achieve robust security and performance.
Context ∞ The application of BFT consensus models is a key discussion point in the development of high-throughput blockchain platforms and enterprise distributed ledgers. Concerns often involve the scalability limitations of classic BFT implementations as network size increases, leading to research into optimized versions. News reports frequently assess BFT models for their security assurances and their ability to process transactions efficiently.
