On the evening of February 27, the third lesson of Babbitt Industry Orientation Class continued. During the live broadcast, Hu Jie, a professor of practice at the Shanghai Advanced Institute of Finance, said that the emergence of blockchain technology involves the three most sensitive businesses in the financial field: securities issuance and trading, fund raising and currency issuance. The logical source of regulation is to weaken / eliminate information asymmetry, protect non-professional investors and prevent systemic risks. He also pointed out that blockchain finance is not new finance, but new technology to do old finance. Regarding the financial application supervision involved in blockchain technology, on a logical basis, it should be treated the same as traditional financial services.
