Verifiable Shuffle Function

Definition

A Verifiable Shuffle Function is a cryptographic algorithm that randomly reorders a set of inputs while providing a mathematical proof that the shuffling was performed correctly and without bias. In blockchain systems, this function is used to ensure fair selection of participants, such as validators or block proposers, without revealing the initial order or allowing manipulation. It guarantees the integrity and randomness of selection processes. This function is essential for decentralized fairness.
