CauchyFold Achieves Theoretical Minimum in Post-Quantum ZK Proof Folding

Researcher Xiang Wang presented CauchyFold, a lattice-based folding scheme proving no less data can be transmitted when compressing multiple post-quantum ZK proofs. The implementation takes 125 KB and reaches the theoretical minimum for the first time.

• CauchyFold compresses multiple post-quantum ZK proofs at once
• Proven that less data cannot be transmitted — theoretical minimum reached
• Working implementation takes 125 KB
