A » A Verifiable Delay Function (VDF) is used in blockchain technology to ensure that a specific amount of time has elapsed before a function's output can be verified. VDFs are crucial for enhancing security, preventing attacks, and ensuring fair sequencing of events in decentralized systems. They provide a reliable method to introduce time delays while maintaining verifiability and resistance to parallel computation attacks.
