Verifiable Random Functions

Verifiable Random Functions are cryptographic primitives that provide a random output along with a proof that the output was generated correctly. They are widely used in blockchain systems to ensure fair and unpredictable outcomes, such as selecting block proposers or determining transaction order.

Because the output is verifiable, participants can be confident that the selection process was not manipulated. This adds a layer of transparency and fairness to the protocol.

In derivative trading, VRFs can be used to generate random settlement times or select participants in a decentralized auction. They are a powerful tool for building trust in automated systems.
