Huang Zhen, a professor at the Law School of Central University of Finance and Economics and director of the Institute of Financial Law, said in an interview recently that in the face of a new wave of development of the blockchain industry, we must prevent the chaos of P2P online lending. The development of the blockchain industry itself has gone through several rounds of repetition. The crux of the problem is that existing laws have gaps or loopholes in the blockchain, that is, the lack of connection and matching of legal systems. Blockchain is a new global thing. In the absence of laws, traditional legislation or law enforcement methods cannot keep up with changes, and a country's individual law enforcement actions will provide practitioners with the use of inconsistent domestic and foreign laws and policies. Opportunities for international evasion. Therefore, recently China's regulatory authorities continue to crack down on virtual currency hype activities with the help of blockchain, especially in Beijing, Shanghai and other places. It is necessary to carry out a new round of cleanup and rectification of virtual currency hype activities.
