According to the 21st Century Business Herald, Liu Feng, an industrial professor at Binjiang College of Nanjing University of Information Science and a member of the China Automation Society's blockchain professional committee, said that the domestic blockchain can be divided into two circles, namely, the chain circle – with technical research, The industry is mainly based on the currency circle – represented by blockchain tokens. On the one hand, the state will continue to support the development of blockchain technology, promote the integration of this technology with various industry sectors, and form an industrialization. On the other hand, the state will maintain a high-pressure supervision of behaviors such as blockchain token financial activities. Liu Feng analyzed, "I think it may be a policy as follows". From a technical perspective, "the central government will formulate standards in the future, preside over and build the main nodes of the blockchain. Local governments follow the specified standards and norms as secondary nodes. Involved in the blockchain system. Because the blockchain is a shared decentralized ledger, it is likely to eventually create a resource pool similar to the national public cloud to all places, while opening up resources and information in various places." It is also said that a city must maintain rationality and do what it takes to develop the blockchain. For first-tier and second-tier cities, whether it is the attraction of talents, technical empowerment or industrial upgrading, the development blockchain is particularly suitable. However, for cities with three or fewer lines, it may be necessary to develop according to their own characteristics, rather than blindly follow the wind to subsidize the frontier technology of similar blockchain. After all, for these cities, the technical talents who create the blockchain may be difficult to meet the demand, and the corresponding supporting facilities will bring financial pressure.
