Definition ∞ Functional commitment refers to a cryptographic technique that allows a party to commit to a mathematical function without revealing the function itself. The party can later open the commitment to prove that a specific output corresponds to a given input under that committed function. This method guarantees the integrity and consistency of computations.
Context ∞ In zero-knowledge proof systems and privacy-preserving protocols, functional commitment is vital for verifiable computation. It enables auditing of complex operations without disclosing sensitive underlying data or logic. Progress in functional commitment schemes is important for building more private and scalable decentralized applications across various industries.
