Definition ∞ A recursive folding protocol is a cryptographic technique that allows for the efficient aggregation of multiple zero-knowledge proofs into a single, smaller proof. This process involves repeatedly “folding” a new proof into an existing one, resulting in a single proof that attests to the correctness of a sequence of computations. This method significantly reduces on-chain verification costs and data storage requirements.
Context ∞ The application of recursive folding protocols is a major advancement in scaling blockchain networks and enabling more complex verifiable computations. Current discussions focus on optimizing the proof generation and verification efficiency of these protocols for practical deployment. Future developments include integrating these protocols into layer-two scaling solutions and privacy-preserving decentralized applications to enhance throughput and reduce transaction fees.
