According to Xinhua News Agency, Guo Yuhang, the head of China's blockchain application research, told reporters that when he was investigating in a central province, the provincial financial department officials revealed that the local authorities had investigated and dealt with more than 40 illegal blockchain flags. In the case of fund-raising, the most serious case involved was more than 2 billion yuan. In addition, many listed companies intend to catch the blockchain fast train. According to statistics, more than 500 of the more than 3,000 A-share listed companies claim to be related to the blockchain, but only 40 of them actually disclose the specific blockchain business content. The phenomenon of “hot spots” is very prominent.
