Definition ∞ Multi-proposer consensus is a protocol design where multiple network participants can simultaneously propose new blocks or transaction sets to be added to a blockchain. This approach contrasts with single-proposer models, where only one entity is selected per round to propose. It aims to increase network throughput and reduce the likelihood of censorship or single points of failure. By allowing parallel block construction, it enhances the efficiency and resilience of the consensus process.
Context ∞ Multi-proposer consensus mechanisms are a significant area of innovation in scaling blockchain networks and improving their resistance to malicious actors. Debates frequently address the challenges of coordinating multiple proposers and ensuring consistent block ordering without introducing new vulnerabilities. Ongoing development seeks to optimize these protocols for speed and security, particularly in sharded or highly parallelized blockchain environments.
