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." Zhu Youping, deputy director of the China Economic Network Management Center of the National Information Center, said that the “Supervision Sandbox” proposed by the Director of the Science and Technology Department of the Central Bank will be the first to be piloted in 10 cities including Beijing, Shanghai and Guangzhou. This is the implementation of the policies issued by the CBRC. This is the real policy sandbox. The policy sandbox is characterized by the use of a blockchain technology platform for supervision and determination of the policy red line, allowing enterprises to break through non-red line policy provisions for innovation, successful promotion, failure notification, punishment, shutdown, and maximum protection of innovation.
