Firstly, in Bitcoin, user identity information is encrypted using hashed public keys, hiding personal information. Additionally, Bitcoin accounts can be designed as one-time-use, with new accounts used for each transaction, thereby increasing the difficulty of tracking user identities. The ledger of Bitcoin is public, but information such as the paying account, receiving account, and transfer amount in each transaction record is confidential.↵↵To further enhance privacy protection, other digital currencies such as Zcash have added some protocols based on Bitcoin, encrypting information about paying accounts, receiving accounts, and  transfer amounts."}]}],"pr":"a3e43205d5cf74382d7c82b73b4d74ebd5bf99cfceff3bfd4a9ea168a14204e6"}
