Verifiable Random Function

Definition ∞ A Verifiable Random Function (VRF) is a cryptographic primitive that generates a pseudorandom output along with a proof that the output was correctly computed. This proof can be publicly verified without revealing the secret input used to generate the randomness. VRFs provide a reliable source of verifiable randomness, which is essential for fair and unpredictable outcomes in decentralized systems. They ensure transparency and resistance to manipulation.
Context ∞ Verifiable Random Functions are frequently discussed in technical cryptocurrency news, particularly concerning blockchain protocols requiring provably fair randomness. They are used in proof-of-stake consensus mechanisms, decentralized gaming, and non-fungible token (NFT) generation to ensure unbiased selection or outcomes. Chainlink’s VRF is a notable example, providing secure randomness to smart contracts. Understanding VRFs is crucial for comprehending the security and fairness of many decentralized applications.
