Xinhua News Agency, Beijing, January 2nd, 2020 is the first year of the third decade of the 21st century. In 2020, the application of blockchain technology will become increasingly widespread and mature. Many governments and enterprises have used blockchain technology to carry out practices in such fields as government services, copyright protection, and product traceability. American Facebook announced last year that it would issue a blockchain-based encrypted digital currency, "Libracoin," and many other countries are preparing to issue their own digital currency. Who will be the first to launch "central bank digital currency" as a big suspense this year.
