In the evolution of crypto finance, privacy protection and transaction verification are often two opposing ends. However, through the combination of zero-knowledge proofs and secure multi-party computation, this dilemma is being broken. These technological solutions enable on-chain transactions to ensure privacy while maintaining verifiability, providing institutional users with new flexibility. Especially in the current rapid growth of the RWA market, solutions that combine privacy and compliance attributes are becoming key channels connecting traditional financial systems with the Web3 world. Whether it is asset onboarding or cross-chain interactions, this technological approach is paving the way for the evolution of industry standards.
