However, the user identity corresponding to the transaction address is anonymous. Through the blockchain encryption algorithm, user identity information and transaction data are separated. Before the data is saved to the blockchain, the user's identity information undergoes hash calculation, and the resulting hash value serves as the user's 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."}]}],"pr":"c72429ded228a32044285ff6c8112a121931385483af2ec7ecdc82e343a8915d"}
