We have long had mixers, privacy coins, and even privacy technologies like zero-knowledge proofs (ZK). However, in complex cross-chain interaction scenarios, privacy protection still has gaps: Limitations of ZK proofs: ZK-SNARKs are good at "proving you know a secret," but in scenarios requiring continuous and complex computations on encrypted data (such as ongoing verification and transformation of cross-chain asset states), their model is not natively designed.
