for example, Sunzi asked Li Zi to borrow 100 yuan, but Li Zi was afraid that he would default, so he asked the village head to do notarization and add the account. This is called centralization. But if you don't ask the head of the village, you can shout "I'll lend my grandson 100 yuan! Please put it in the account book. "This is called decentralization. In the past, the village head was highly respected and had a good command of the accounts of the whole village. Everyone kept their money with him. This was the past trust in centralization. Now, everyone is worried that the village head will secretly misappropriate everyone's money. What should we do? So everyone sent an account book to everyone. Anyone who transfers money between them releases information through the loudspeaker. After receiving the information, everyone records the transaction in their own account book. This is called decentralization. With distributed ledgers, it doesn't matter if Lao Zhang or Lao Li's ledgers are lost, because Lao Zhao, Lao Ma and other families have ledgers

5. bitcoin is a "digital currency" based on blockchain technology. In 2013, the central bank made it clear that bitcoin, as a specific virtual commodity, does not have the same legal status as currency and cannot and should not be used as currency in the market.

Bitcoin, with the characteristics of globalization, is usually used as a tool for cross-border payment and remittance. As a kind of network encryption virtual currency, bitcoin has the characteristics of decentralization and anonymity,
capital flow is not easy to track, and it is easier to hide identity
