A » A Verifiable Delay Function (VDF) is a cryptographic primitive that requires a specific amount of time to compute and produces output that can be quickly verified. In blockchain, VDFs are used to ensure fairness and security by delaying actions like block creation or transaction processing, preventing premature advantage by adversaries. Their time-bound nature is crucial for applications needing predictable execution times, ensuring decentralized consensus and trustworthiness in distributed systems.
