Zhao Lei, a researcher at the Institute of Law of the Chinese Academy of Social Sciences, said recently that in the face of the blockchain, it is necessary to be less impetuous and more rational. The blockchain can only benefit the social or public interest if it is used in a specific scenario. Accurate understanding and rational use of blockchain technology is the right way. Establishing unified and standardized technical standards is an urgent problem to be solved in the development of blockchain. Relevant departments should introduce standards as soon as possible to provide a basis for supervision.
