Decentralized data cryptosystem proposed the Mix-ZK protocol, which combines the principles of "hybrid data structure" and "zero-knowledge succinct non-interactive knowledge argumentation (zk-SNARK)", it can ensure the anonymity of users, the privacy of message transmission, and the privacy of data structures. With the Mix-ZK protocol technology, we first developed a BSC-based decentralized encrypted credential system DCS. And the code is disclosed, the resolution method is transparent, and the smart contract is automatically executed in such a system. Also, it provides users with digital asset security and privacy so that can create a new transaction model that is decentralized, hidden, secure, shared, and mutually beneficial. In addition to solving the privacy problem of cryptocurrency, Mix-ZK can also improve the efficiency of the network. Miners do not need to re-execute the calculation of the transaction, but just need the other party to obtain proof, which can greatly compress the amount of information and greatly increase the throughput of the network.

The core algorithm of the DCS encryption certificate protocol is the Mix-ZK protocol, which combines the "hybrid data structure" and "zero-knowledge succinct non-interactive knowledge argumentation (zk-SNARK)" principles so that to ensure the anonymity of users, the transmission of messages, and data structure privacy.

The Basic Functions of DCS:

• Issuing and receiving vouchers
• Issuing a certificate for mining
• Pledge and profit-sharing function
• User's own wallet operation.

The Features Of DCS:

• Security
• Convenience
• Privacy
• Complexity
• Incentive: In order to ensure privacy and complexity, the DCS platform has designed a set of user incentive systems of "certificate issuance for mining" and "node governance" to incentivize users who are optimistic about this demand and have digital asset privacy Protect users in need, and share the benefits of the DCS platform through behavioral mining and mobile pledge mining.
