In May 2018, the Information Center of the Ministry of Industry and Information Technology of the China Academy of Information and Communication officially issued the White Paper on the Development of China's Block Chain Industry in 2018. According to the data, there are 456 companies whose main business is Block Chain in China.
In September 2018, at the 2008 National Cyber Security Publicity Week, Xintong Hospital issued the "Block Chain Security White Paper - Technology Application Paper". It talked about the current block chain has become a hot spot of technological innovation and market pursuit. The security risks and technical characteristics of block chain technology have brought a lot to technology application and network security supervision. Challenge.
"The state attaches great importance to the research of block chain technology and the application and development of the combination of block chain technology in various fields with block chain technology," said Wei Kai, director of the Cloud Computing and Large Data Research Institute of China Telecom and Communications Institute. Trust relations, improve collaboration efficiency, promote data sharing, enhance the government's penetrating regulatory capacity and other aspects of the irreplaceable role.
The following is an interview transcript.
Chain Dee: Your previous research has been in the field of cloud computing and large data, from a technical point of view, how to look at the relationship between the Internet and block chains?
Wei Kai: Block chains are a patch to the Internet, and their primary role is to enhance trust and make up for the shortcomings of Internet technology. Because the rules of block chains are transparent, fixed, and algorithmically recorded, they can somehow replace organizations and help organizations do better.
But I don't think block chains can disrupt the economy. They may exist in a long-term technological way in the future, with limited integration with real enterprises. But this process won't happen overnight. It will take time to infiltrate into specific application scenarios.
The chain is available: block chaining technology is widely experimented in the financial field, and what financial scenarios are suitable for it? What are their commonalities?
Wei Kai: Block chain technology has a lot of research space in supply chain finance, risk information sharing mechanism and cross-border trade. The commonalities of these financial scenarios include: more participating nodes, high cost of authenticity, long transaction process, and the characteristics of the block chain, such as distributed accounting, unauthorized, built-in contracts can provide solutions to these financial business pain points.
Chain Dede: This morning, Dong Jin, vice president of IBM China Research Institute, said: There are no more than 10 teams in China who really understand the bottom technology of block chain. Do you think your technical team is in these 10 teams?
Wei Kai: Domestic block chain technology really has a lot of room for progress. At present, many technologies do have traces of imitation of foreign countries. Our team mainly tests block chain technology, in addition to establishing a "trusted block chain" to help different enterprises in the block chain industry to communicate.
The chain is available: what are the unresolved difficulties in the current block chaining technology?
Wei Kai: The development of block chain technology is still at a very early stage. At present, the first difficulty is to solve the problem whether the block chain technology itself is trustworthy. Is the machine more reliable than the organization because we entrust trust to the machine rather than to an organization? It seems theoretically not necessarily equal sign, this machine is higher than the organization's credit, performance, function, security in the end can carry the pressure of the system, the first block chain to prove itself innocent, to be trustworthy.
Secondly, how to anchor under the chain? The chain is a virtual world, and the chain is a physical world. How can the boundary between the virtual world and the real world be anchored? Especially in traceability and certification, if the piece of information on the chain has been faked, the block chain is powerless, which requires a lot of supporting measures outside the block chain to ensure, may be technical, may be regulatory, may be other.
At the same time, the effective governance of the public chain itself is also a major difficulty, it is necessary to improve the running speed of the public chain and the alliance chain itself through various technologies, such as fragmentation, to ensure the stability of the operation.
In addition, we also need to face the legal supervision, legitimacy issues, how to adapt to the existing rules system? Especially in the legal status, Token's legal status, as well as anti-money laundering, customer identification, privacy protection and other aspects, how to clear the information after the chain, there is a big problem, I think the block chain in fact to face these tests, or need some time.
Especially when the block chain technology serves the real economy, we need to constantly adapt to the changes in different scenarios. Overall, the block chain ideal is very rich, but the reality is very grim, the need to face a lot of challenges.
Chain: from a technical point of view, how do you view the chain industry?
Wei Kai said: many enterprises have "anxiety" about block chain technology, fearing that they will not catch up with the hot spots and are very impetuous. But we should think about whether or not we need to use block chains, consider the application cost of block chains, and consider our own scenarios need a database? Do you need multiparty writing? Can transactions be made public?
There is a big gap between the ideal and reality of the current block chain, such as the exclusion of "de-centralization" by the original centralized organization, and the imperfection of the legal system on which intelligent contracts rely. Although there is a gap between the reality and the ideal, the development and application of technology will take time. It is also based on this that a trusted block chain alliance is established to guide the development and application of block chain technology from the aspects of technology, application and policy.
