Through the blockchain encryption algorithm, the separation of user identity and user transaction data is achieved. Before the data is saved to the blockchain, the user's identity  information is hashed, and the resulting hash value serves as the unique identifier. The chain saves the user's hash value rather than the real identity data, and the user's transaction data is bundled with the hash value rather than with the user's identity information.
