Cryptographic Self-Sortition

Definition ∞ Cryptographic Self-Sortition is a method used in some blockchain protocols to randomly and verifiably select participants for specific roles, such as block production or committee membership. This process employs cryptographic primitives to ensure fairness, unpredictability, and resistance to manipulation. Participants typically apply with a stake, and the protocol uses a verifiable random function to choose them. This mechanism promotes decentralization and security within the network.
Context ∞ News concerning the governance and consensus mechanisms of new or existing blockchain platforms often references Cryptographic Self-Sortition. Protocols like Algorand use this technique to achieve high transaction throughput and security without relying on a small set of validators. Its implementation is a key discussion point for assessing a network’s decentralization properties and attack resistance.
