PoS Committee Selection

Definition ∞ PoS committee selection is the process by which a subset of validators is chosen to perform specific tasks, such as proposing or validating blocks, within a Proof-of-Stake (PoS) blockchain network. This selection often employs a verifiable random function to ensure fairness and unpredictability. The committee is responsible for maintaining network consensus and security for a designated period. Its integrity is crucial for the chain’s operation.
Context ∞ PoS committee selection is a critical security and decentralization aspect of Proof-of-Stake blockchains, directly influencing network resilience against attacks. Ongoing research and development focus on optimizing these selection mechanisms to enhance fairness and prevent collusion. News often details upgrades to PoS protocols that modify or improve how these committees are formed and operate.
