But there is even more information than the bank employees, there is a channel for which money, IP, etc. went. A lot of technical information. As I have already pointed out - money, these are numbers and they do not go anywhere from nowhere, there is always targetedness. Block is the chain of blocks. In each block you will find all the exhaustive information on a specific transaction. But when someone sent money to someone and they reached the addressee, everyone is happy, all these blocks are not deleted, they are collected in a chain, their copies are saved. So you can trace the whole chain. This thread can be traced by any user. So all operations become transparent. And we know whom to deal with, and with whom we need to think.
