VECTIS: Efficient Batching Framework for Group-based CP-SNARKs
Abstract
Blockchain applications in finance and identity management increasingly require scalable and privacy-preserving solutions. Cryptographic commitments secure sensitive data on-chain, but verifying properties of these commitments efficiently remains challenging, particularly in large-scale scenarios. For multiple commitments, CP-SNARKs, a family of zk-SNARKs, enhance prover efficiency by shifting large-cost operations outside the circuit and verifying linkages between commitments, but incur verifier-side overhead due to linkage checks. Verification costs grow with the number of commitments, leading to inefficiencies in key size, proof size, and verification time.
