Xie Ping, dean of the Wudaokou Finance College of Tsinghua University, pointed out that for the non-sovereign global stable currency, at the G20 finance ministers and central bank governors meeting held in October this year, the 20 central banks publicly stated that the premise of global stable currency issuance. It must solve the problem of anti-money laundering, anti-terrorism financing, integrity, and consumer protection. "This is actually a temporary freeze on non-sovereign stable currencies, especially non-sovereign stable currencies based on blockchain technology." Xie Ping believes that the private sector should have three conditions to participate in infrastructure and provide public goods: first, to solve the problem of charging; second, to strictly supervise; third, to have a public good, and to have a higher moral level willing to provide services to the public. However, the third article is difficult to achieve and can only be achieved under strong supervision.
