Interactive Oracle Proof

Definition ∞ An Interactive Oracle Proof is a cryptographic proof system where the prover and verifier engage in a series of communications to establish the validity of a computation. The verifier queries the prover, who acts as an oracle, about different parts of the computation, and the prover responds with compact proofs. This interactive process allows for efficient verification of complex statements with a high degree of confidence. It forms a basis for certain zero-knowledge proof constructions.
Context ∞ Interactive Oracle Proofs represent a theoretical advancement in the field of verifiable computation, providing a framework for constructing highly efficient and secure proof systems. Researchers continue to optimize their interaction complexity and proof size. These proofs are foundational for developing scalable and privacy-preserving solutions in decentralized networks, including rollups and verifiable computation services.
