The absence of privacy protection in public chains is one of the core factors hindering users, especially enterprise users, from using and building blockchain-based commercial applications. To address this issue, Axiomesh needs to provide users with powerful privacy protection capabilities. Combining design principles,Axiomesh proposes the compliant and privacy-compatible protection protocol DCPA (Decentralized Confidential Protocol with Auditability). DCPA adopts a twin-token model in its overall architecture to ensure the composability and flexibility of the protocol. It is based on cutting-edge cryptographic technology to ensure the security and privacy of transaction content and identity while ensuring regulatory compliance. In the following section, we will introduce our zkToken, zkDID.
