Payee confirms the signer of the document
After Lao Li got the order, he needed to confirm that the order was actually signed by the person "HIJKLMN" (that is, Lao Zhang). This is not difficult. Because there must be a confidential seal on the list, Lao Li takes out the seal scanner and scans the chapter. If the characters displayed on the LCD screen are the same as those of the payer (here "HIJKLMN"), you can confirm that the list is indeed the payer Signed. This is because according to the confidential seal mechanism, no one else can forge the seal. Anyone who scans the seal can confirm whether the payer and the person who stamped the bill are the same.

The payee confirms the payer's balance
This system is still very problematic so far. Through the confidential seal, although the payee can confirm that the payer has indeed signed this form, it cannot confirm whether the payer has enough balance to pay. In the previous central virtual currency system, Ergouzi was responsible for checking the payer's balance and notifying the payee whether the transaction was valid. Now that Ergouzi is opened, who is responsible for keeping accounts and confirming the validity of each transaction?

As I said before, the system designed by Satoshi Nakamoto is a distributed currency system that does not rely on any central person, so there will not be one or a few people responsible for this matter. The miner mentioned above will ultimately take on this job. organization. Lao Zhang, Lao Li and any other villagers in the village who use Bitcoin for transactions rely on the work of miners to complete the transaction.
