VRF Sortition

Definition ∞ VRF sortition is a method for randomly selecting participants in a decentralized network using Verifiable Random Functions (VRFs). A VRF produces a random output along with a cryptographic proof that the output was generated correctly and without bias. This ensures a fair and unpredictable selection process for roles like block proposers.
Context ∞ VRF sortition is a key component in many proof-of-stake blockchains, providing a secure and transparent way to choose validators or other network participants. News often discusses the implementation and security audits of VRF schemes in new protocols. Its ability to provide provable randomness is essential for maintaining the integrity and decentralization of consensus mechanisms.
