This newly appointed Ergouzi is smart, but sometimes this person is smart but is mistaken for being smart. One day Er Gouzi stared at the ledger, thinking that whoever has the money in this village is what I said, then I am.... So he got a hot head and privately drew ten grams of gold from the old Zhang account to his own name.
I thought it would be perfect, but I didn't expect that Lao Zhang also had the habit of keeping accounts. One day he was about to pay but was told by Er Gouzi that his account was out of money. Lao Zhang checked his own account book, and there were clearly ten grams left, so he took the account book to find Ergouzi theory. This check found the transfer without Zhang's consent.
East window incident! Bit Village exploded. Ergouzi's impeachment is inevitable, but through this incident, everyone discovered the drawbacks of concentrating the ledger in one person's hands:
This system is completely dependent on the personal credit of the book holder. If this person does not follow the rules and tamper with the book at will, then the entire currency system will collapse
If this person’s home catches fire or the books are stolen, it will also bring a devastating blow to the entire system
Just when people were at a loss, an otaku scientist named Satoshi Nakamoto in the village stepped onto the stage and told everyone that he had designed a virtual currency system called Bitcoin that did not rely on any central processor to solve the above problems. Then he slowly recounted his plan.
Let's take a look at how Satoshi Nakamoto designed this system.
