What are the practical applications of blockchain technology in economics?

Digital currency, pioneered by blockchain technology, has had a great impact on the financial sector. The research and application of blockchain technology has become an important topic in the financial field today. In essence, blockchain technology still belongs to a technical means and tool. Its application in the financial field and its application in the real economy are parallel, with their own relative independence, but there is a certain overlap, which means that the promotion of the real economy is indirect. 1. Trust is one of the bases of transactions between suppliers and customers, whether it is financial or entity. At present, banks, enterprises, enterprises, etc. It's all about money. The right to issue money belongs to the state and the right to operate it belongs to the bank. With the further popularization and wide application of blockchain technology, enterprises and enterprises, or individuals and individuals can issue digital currency (digital credit) by themselves in the future, and the status of banks will change from the current monopoly operation to the equal competition operation in the market. Therefore, the wide application of blockchain technology in the financial field has had an indirect impact on the real economy. 2. Blockchain technology is a bridge between reality (entity) and virtuality. Through blockchain technology, the real world can be recreated, reconstructed and redefined in the virtual world. For example, real paper money is digital currency in the virtual world, real stock trading is digital trading in the virtual world, and real import and export trade is digital settlement, digital customs clearance, digital documents and bills in the virtual world, which can greatly improve the efficiency of business processes and save transaction costs. At present, all transactions are inseparable from banks, which play a central role in transactions. The application of blockchain technology by banks will definitely improve the efficiency of their settlement and indirectly promote the efficiency of the real economy, but this influence will gradually weaken in the future. Because the biggest feature of blockchain technology is decentralization, its distributed billing system is a decentralized network system. 3. The application of blockchain technology is actually to value and credit the information flowing on the Internet at present. It is of great significance to reorganize and reconstruct the information (use value, exchange value and cultural value) on the Internet through blockchain to form a value Internet, which will bring revolutionary impetus to both the financial industry and the real economy.
