Definition ∞ BFT-based security refers to the safety assurances provided by Byzantine Fault Tolerant consensus mechanisms in distributed systems. These protocols allow a network to reach agreement even when some participants act maliciously or fail unexpectedly. This approach provides robust fault tolerance, making systems resilient against a significant number of faulty nodes. It is a critical component for maintaining data integrity and availability in decentralized environments.
Context ∞ BFT-based security is a central topic in the development of various blockchain platforms and distributed ledgers, particularly those aiming for high transaction throughput and quick finality. The ongoing discussion centers on balancing the strong security guarantees of BFT with scalability and decentralization in practical implementations. Innovations in BFT protocols are continually being developed to enhance the performance and reliability of digital asset infrastructure.
