Proof Folding Scheme

Definition ∞ A proof folding scheme is a cryptographic technique used to compress multiple proofs into a single, smaller proof, thereby significantly reducing the computational and storage overhead required for verification. This method iteratively combines proofs of sequential computations, creating a succinct representation that can be verified more efficiently. It is particularly valuable for scaling blockchain applications by allowing complex computations to be proven off-chain and then verified on-chain with minimal cost. This innovation enhances the practicality of zero-knowledge proofs.
Context ∞ Proof folding schemes are a cutting-edge development in zero-knowledge cryptography, often highlighted in technical crypto news as a solution for improving blockchain scalability and efficiency. Projects building layer-2 solutions or privacy protocols are actively researching and implementing these schemes to reduce transaction costs and increase throughput. The ongoing advancement in proof folding represents a key area for enabling broader adoption of decentralized technologies.
