What is a core problem solved by Bitcoin?
Pre-reading reminder
if you already know what problem Bitcoin is designed to solve, you can see it here. The content of this article is from an internal popular science sharing, mainly to give people who come into contact with Bitcoin for the first time to have a preliminary understanding.
Setting up a scene is a problem.
assumes that a Chinese farmer has a business of RMB 100 with a British fertilizer plant (perhaps buying a generation of chemical fertilizer). We compare the existing financial system with Bitcoin's financial system to study the value of Bitcoin.
The current financial system
according to the modern financial system, the transfer of 100 yuan can only be completed through the SC,HSBC,ICBC of three banks, and this huge financial system needs resources to maintain, that is, they have to charge fees. It is conceivable that 100 yuan is not enough for the three major banks to run a lap, so at present, there is no small amount of cross-border remittances, and the financial cost determines that small businesses cannot be done.
How is Bitcoin accomplished?
through the above popular science description, we know that the cost of the modern financial system is mainly spent on the maintenance of the financial system. If we want to reduce the cost of financial turnover, we need a new financial system.
because we believe in the financial system, so the financial system provides services for us and charges our fees, so why can't we trust each other? In this way, there is no need for a financial system, and costs are reduced.
Bitcoin officially uses the above idea. When A wants to transfer money to B, he will shout that I will transfer 100 yuan to B, everyone can hear it! Then all the people who heard it would take a small notebook and write it down, A transferred to B100 yuan, a total of late transaction inquiries, why should they help An and B complete the transaction? What if B doesn't receive the money? What about counterfeit money from A to B?
The above problems of must always be solved, otherwise the great idea of bitcoin cannot be implemented on the ground. the solution is the famous "blockchain". We will use other pages to explain the content of "blockchain".
