On the evening of January 3, the third debate of SheKnows's final debate at the end of the year began. The theme of this debate was "2020, the year when the public chain supervision broke the game." Bai Liang, founder of Zero One Finance and executive deputy dean of the Digital Asset Research Institute, said that the problem of public chain supervision: how to integrate decentralized community governance with strong center supervision. They are not completely contradictory, but there are realistic conflicts in terms of the concept, scope, and methods of supervision. From the perspective of technical supervision, there is no regulatory compatibility issue, and the blockchain can be treated in accordance with the normal technical supervision mode. However, the difficulty of financial supervision lies in the tokens generated based on the blockchain model. At present, there are two commonly used supervision methods of financial supervision: one is subject supervision (who is doing it), and one is behavior supervision (what is it doing).
