Cryptographic folding refers to a technique employed in zero-knowledge proof systems to compress multiple statements into a single, more compact statement without compromising verifiability. This method permits the aggregation of numerous proofs or computations into a smaller, more efficient representation. By repeatedly “folding” intermediate proofs, the overall proof size and verification time can be significantly reduced. This process is essential for scalability in certain blockchain architectures.
Context
Cryptographic folding is a relatively advanced concept gaining traction in the pursuit of highly scalable and private blockchain solutions, particularly for Layer 2 scaling protocols. Projects leveraging this technique aim to process a large volume of transactions off-chain and then submit a single, succinct proof to the main chain. News and technical discussions frequently highlight breakthroughs in folding schemes, as they promise to address some of the most pressing scalability challenges in the digital asset ecosystem.
The first lattice-based folding protocol enables recursive SNARKs to achieve post-quantum security while matching the performance of pre-quantum schemes.
