Recursive Compression

Definition ∞ Recursive compression is a technique used in cryptography, particularly within zero-knowledge proofs, where a proof itself can be compressed and then included as part of a new, larger proof. This method allows for the aggregation of multiple proofs into a single, compact proof, significantly reducing the data size and computational cost required for verification. By repeatedly applying this compression, it enables the verification of extensive computational histories or complex transactions with minimal on-chain data. This technique is crucial for enhancing blockchain scalability.
Context ∞ Recursive compression is a cutting-edge development in zero-knowledge technology, holding substantial promise for addressing blockchain scalability limitations. Current research focuses on optimizing the efficiency of these recursive proofs and expanding their applicability to various decentralized applications. The ability to verify vast amounts of off-chain computation with a small on-chain footprint represents a significant advancement for layer-2 solutions and cross-chain interoperability.
