Accounting book disclosure mechanism

Satoshi Nakamoto first explained that the existing account books should be modified as follows:

The account book no longer records the balance of each villager, but only records every transaction. That is to record the payer, payee and payment amount of each transaction. As long as the initial state of the account book is determined, and each transaction record is reliable and time-series, how much money each person currently holds can be calculated.
The account book is changed from private to public. As long as any villager needs it, the current complete account book can be obtained. The account book records all transaction records from the creation of the account book to the current one.
As soon as this remark came out, the pan was fried immediately below. The first article doesn't matter, but the second article is simply unacceptable, because the account book records all the villagers' transactions, so that everyone's privacy is not fully exposed.

Satoshi Nakamoto took out a pair of strange things without rushing.
