Recursive Folding

Definition ∞ Recursive folding is a cryptographic technique where a proof of computation can verify another proof of computation, allowing for the repeated compression of proofs. This method significantly reduces the data size and verification cost for complex operations or long sequences of transactions. It enables the creation of highly scalable systems by consolidating multiple proofs into a single, succinct proof. This process is vital for off-chain scaling solutions.
Context ∞ Recursive folding is a rapidly advancing area in zero-knowledge proof research, directly impacting the viability of various blockchain scaling solutions, such as ZK-rollups. Discussions often focus on optimizing the efficiency and security of these recursive constructions. Future developments in this domain are anticipated to dramatically reduce the computational overhead for verifying large volumes of off-chain transactions on mainnets.
