For example, in Bitcoin, user identity information is hidden through hashed public keys, and users can set up one-time accounts to make it difficult to trace transactions on specific accounts. Additionally, the total ledger of Bitcoin is public, but the transaction records do not contain personal information. To further enhance privacy protection, certain digital currencies such as Zcash have added protocols based on Bitcoin, hiding paying accounts, charging accounts, and transfer amounts while utilizing technologies such as encryption, hashing, Merkle trees, and zero-knowledge proofs. Through these methods, blockchain technology can protect individuals to a certain extent."}]}],"pr":"86c1bed3b73d77600bc27c53b791c3462130eae7309bf91492476f585be5bcbc"}
