Recently, Huang Zhen, director of the Institute of Financial Law of the Central University of Finance and Economics, published an article entitled "The Hike of Digital Currency Issuance." The article pointed out that although optimists are full of expectations for the Libra distribution plan and give high praise, we still have to return to the real world. The current world is a world composed of sovereign states. Since the currency is currently a financial instrument for credit endorsement and supervision in sovereign countries, whether Facebook can implement the Libra plan, and wait for the final decision of the US Congress, also requires Switzerland. The financial supervisory authority intervened reasonably. Facebook's Libra currency program has drawn the attention of sovereign countries and will inspire them to further accelerate the exploration of sovereign digital currency research and development. Therefore, in general, the Libra plan is an important opportunity to accelerate the global currency into the digital currency phase, perhaps to promote the global digital currency regulatory framework, and to stimulate contemporary economists and financial scientists to rethink monetary and financial theory and financial supervision. The system keeps pace with the new round of scientific and technological revolution and financial reform.
