Definition ∞ Leaderless BFT protocols are a class of Byzantine Fault Tolerance consensus algorithms that do not rely on a single designated leader node to propose blocks or orchestrate the consensus process. Instead, all participating nodes collectively contribute to reaching agreement on the order and validity of transactions. This distributed leadership structure enhances censorship resistance and removes a single point of failure, improving the network’s resilience against malicious actors or node failures. It offers stronger decentralization properties.
Context ∞ Leaderless BFT protocols are gaining attention in the pursuit of more robust and truly decentralized blockchain networks, aiming to avoid the potential bottlenecks or attack vectors associated with leader-based systems. Research focuses on optimizing their communication overhead and scalability while maintaining strong security guarantees. These protocols are often considered for high-performance, permissioned blockchain applications where trust among participants is established.
