FRI Protocol

Definition ∞ The FRI Protocol, or Fast Reed-Solomon Interactive Oracle Proofs of Proximity, is a cryptographic primitive used to construct highly efficient zero-knowledge proofs. It allows a prover to demonstrate knowledge of a large computation to a verifier with minimal communication and computational cost. This protocol is fundamental for scalable and private blockchain solutions.
Context ∞ News often references the FRI Protocol in discussions about advanced zero-knowledge technologies and their application in scaling blockchain networks, particularly layer-2 solutions. Its efficiency is critical for enabling complex computations off-chain while maintaining on-chain verifiability. Developments in FRI contribute significantly to the future of privacy and scalability in crypto.
