FRI Commitment Scheme

Definition ∞ The FRI Commitment Scheme is a cryptographic primitive utilized in zero-knowledge proofs, specifically for proving the low-degree property of polynomials. It allows a prover to commit to a polynomial and later demonstrate, with minimal communication, that the polynomial indeed has a low degree. This scheme forms a core component of highly efficient and scalable zero-knowledge proof systems. It is fundamental for compact proof generation.
Context ∞ FRI commitment schemes represent a significant area of advancement in the field of zero-knowledge cryptography, particularly for ZK-rollups and other scaling solutions. News frequently discusses how FRI contributes to reducing proof sizes and verification times, making these technologies more practical for widespread use. Continued research aims to further optimize its performance and expand its applications in privacy-preserving digital assets.
