A leaderless consensus model describes a decentralized agreement system without a central block producer. In such models, all participating nodes have an equal opportunity to propose or validate blocks, often through mechanisms like random selection or round-robin scheduling. This design aims to enhance censorship resistance and reduce the risk of single points of failure or malicious control. It contrasts with leader-based protocols where a designated node coordinates block creation, which can sometimes lead to centralization concerns.
Context
The pursuit of true decentralization often leads blockchain researchers to develop and refine leaderless consensus models. News frequently covers new protocols or upgrades that aim to eliminate leader dependency, particularly in discussions about network resilience and equitable participation. The challenge involves achieving high transaction throughput and low latency while maintaining strong security guarantees in a leaderless environment.
