PCCS (Cross-Payment Chain) is a project dedicated to realizing cross-chain anonymous payment solutions for privacy in the blockchain world. PCCS introduces the concept of a distributed anonymous payment scheme, which has the function of a complete decentralized electronic currency with strong anonymity guarantees and security guarantees, and proved its security under certain cryptographic assumptions. This structure takes advantage of recent advances in the field of zero-knowledge proofs. Provide a more stable and secure platform for cross-chain ecological construction.
