Recursive SNARK

Definition ∞ A Recursive SNARK is a type of Zero-Knowledge Succinct Non-Interactive ARgument of Knowledge where a SNARK proof can verify another SNARK proof. This allows for the creation of proofs that can verify arbitrarily long computations in a compact and efficient manner. It significantly improves scalability by enabling the aggregation of many transactions or computations into a single, verifiable proof. This cryptographic primitive is fundamental for advanced blockchain scaling.
Context ∞ Recursive SNARKs represent a significant breakthrough in zero-knowledge technology, frequently featured in discussions about the future of blockchain scalability. Projects building layer-2 solutions and privacy-focused protocols are actively developing and deploying recursive SNARKs. The ongoing challenge involves optimizing their computational efficiency and ensuring their cryptographic security for broad adoption.
