Chen Chun, an academician of the Chinese Academy of Engineering, published an article "The Blockchain Industry Ecology Begins with Strong Supervision before It Can Be Stable and Far-reaching: Talking about Blockchain Technology, Application and Regulatory Challenges". He said that the continuous deepening of blockchain applications has also brought a series of risk challenges. There are three main challenges to risk. The first is the threat to network security; the second is the anonymity of public chains and the difficulty of deleting information, which can easily be used to spread bad information, which poses a challenge to ideological security; the third is the challenge to financial security. "Blockchain" flags frequently carry out illegal financial activities, disrupting the normal financial order. For the current development trend of blockchain supervision technology, there are four main aspects. The first is the tracking and visualization of blockchain nodes; the second is the penetrating supervision technology of the alliance chain; the third is the active discovery and detection and disposal technology of the public chain; The last is to study the architecture and standards of governing the chain by chain.
