Committee Sortition

Definition ∞ Committee sortition is a method used in decentralized governance to randomly select a group of participants for specific decision-making or validation tasks. This process aims to ensure fairness and prevent centralization of power by making the selection unpredictable. It enhances the security and impartiality of operations within a decentralized system. The selection is typically performed using verifiable random functions on the blockchain.
Context ∞ Committee sortition is a subject of ongoing research and implementation within various blockchain protocols, particularly those requiring a rotating set of validators or oracle providers. The situation involves designing robust randomness sources that are resistant to manipulation. A critical debate concerns the optimal size and rotation frequency of such committees to balance security with operational efficiency. Future developments will likely involve more advanced cryptographic techniques to ensure the integrity of the sortition process.
