Definition ∞ A committee sortition protocol is a method used in some blockchain consensus mechanisms to randomly select a small group of validators to perform specific tasks, such as proposing or validating blocks. This process uses verifiable randomness to ensure fair and unpredictable committee selection. Its purpose is to enhance decentralization and resistance to attack.
Context ∞ The security and fairness of committee sortition protocols are key topics in sharded blockchain designs, where committees process transactions for specific shards. Ongoing research focuses on improving the randomness and resilience of these protocols to prevent malicious actors from predicting or influencing committee membership.
