Today, Li Guoquan, a professor of financial technology and blockchain at Singapore's New Yueshe University, said that we feel that Libra has brought a rare opportunity for the world to replace sovereign currencies such as the US dollar as an international currency. After the global financial crisis broke out, in the study of super-sovereign currency, there were people who reformed the International Monetary Fund's Special Drawing Rights (SDR) to enable it to become a super-sovereign world currency for research or exploration to supplement the current international currency. The system has inherent flaws.
