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 user's unique identifier. Instead of storing real identity data information on the chain, the user's transaction data is bundled with the hash value, protecting user privacy."}]}],"pr":"c41783facfac6976627a80f5fdf8a7fa9d974ef870a7f3af173df5d81be1e276"}
