"How do we embed the blockchain system into the current traditional trusted system to solve some of its problems, or in turn use our blockchain system to release the traditional information system, and the data collaboration requirements under the chain chain may be Of particular importance is the requirement that data on the chain can be effectively coordinated to ensure the relevance and consistency of the data under the chain."
Gray hair, rimless glasses, light blue shirt, Chen Chun appeared in the image of a typical Jiangnan talent. When talking about the experience of collectively studying the blockchain to the Political Bureau of the CPC Central Committee, this professor who devoted most of his life to technical research Excited, "On October 24th, after listening to the general secretary's important instructions on the blockchain, I was greatly encouraged as a researcher of blockchain technology, and I feel deeply responsible."
Chen Chun expounded the understanding of blockchain technology from three aspects: technical research, industrial application and regulatory services.

Who is Chen Chun?
On the afternoon of October 24, the Political Bureau of the CPC Central Committee conducted the 18th collective study on the status quo and trends of blockchain technology development. Chen Chun explained the issue on the same day and talked about opinions and suggestions.
According to public information, Chen Chun was born in 1955, Xiangshan, Zhejiang. In January 1982, he graduated from Xiamen University with a bachelor's degree in mathematics control theory. In June 1984, he graduated from Zhejiang University with a master's degree in computer application. In 1990, he graduated from Zhejiang University with a Ph.D. in computer application.
Chen Chun worked in the Department of Computer Science of Zhejiang University since 1984. He has served as the director of the Department of Computer Science and the Dean of the School of Computer Software. In addition to his position at Zhejiang University, Chen Chun has also served for a long time in Zhejiang University's listed company Zhejiang University New Technology Co., Ltd. (Zheda Netnew, 600797.SH). In 2001, he served as the new president of Zhejiang University. From 2002 to April 2010, he served as the new chairman of Zhejiang University. Since then, he has served as honorary chairman until April 2014.
What is the blockchain?
Chen Chun summarized the four main points of the blockchain: single-point initiation, full-network broadcasting, cross-validation, and common accounting.
He gave an example of the image to explain that Zhang San, a villager in the village, borrowed a hundred dollars from Li Si. He broadcasted this information to all the villagers through the radio station in the village. All the villagers passed the point-to-point verification before they took this. The information is recorded on its own books, and this chain, which is recorded in chronological order, is the blockchain. Can be traced back, not tampering, credible.
"Can not borrow the name of the blockchain to speculate." Chen Chun stressed that there are often some misunderstandings in the public understanding, such as linking the blockchain to cryptocurrencies such as Bitcoin. In Chen Chun's view, the most important application space for future blockchain technology in China is in the fields of industrial manufacturing.
“By linking the information of upstream suppliers, factory manufacturing and downstream customers, the blockchain can form new credit guarantees with its traceability and non-tamperability, thus shortening the chain of trust, enhancing the trust coordination of the industry chain, and improving production. Efficiency." Chen Chun said.
The application of blockchain technology has transformed the information Internet into a new era of value Internet.
Chen Chun believes that the standard, fusion blockchain chain and chain data collaboration model framework, currently need to study four technical points, these should be the development direction of data collaboration under the chain chain. First, the large-scale high-efficiency peer-to-peer network, around the blockchain application, Chen Chun believes that this is the most important, because the blockchain is originally point-to-point transmission, if the network technology does not break, the performance of the blockchain system is difficult to improve. The second is the modular security cryptography protocol. The third is a high-performance programmable computing engine that writes smart contracts in different programming languages and requires a high-performance programmable computing engine. The fourth is a definable data distribution protocol.
What is the use of blockchain?
At this stage, the Zhejiang University Blockchain Research Center is mainly engaged in technical research in the areas of alliance chain and blockchain supervision.
Chen Chun said that the industrialization of alliance chain is also widely used in China, such as financial industry, legal field, medical field, energy field, and public welfare field. "The domestic and foreign blockchain applications are still different. The development of the western blockchain is basically based on financial innovation to drive other industry innovations. In addition to financial innovation, China is more important in various industries."
In the financial field, Chen Chun introduced that in 2017, Zheshang Bank launched the industry's first “receivable chain platform” based on blockchain technology, by “sending” the accounts receivable of SMEs into digital certificates. Save 80% of the time cost and reduce the financing cost by 50%.
Blockchain and 5G convergence will have more power. The transmission process of 5G is very efficient, but the transmission network is opaque, so it is necessary to confirm the true identity and trust level of the other party. The blockchain solves the problem of trust on the Internet. The two are integrated and developed, and cross-border integration.
Chen Chun believes that under the framework of reasonable supervision, using the fundamental characteristics of the blockchain, combined with the real economy, people's livelihood, social governance, etc., the blockchain can become another weapon for China's new round of scientific and technological revolution and industrial transformation.
How is the blockchain regulated?
The regulation of blockchain applications, especially with the blockchain as the underlying technology of cryptocurrency chaos, is now a topic of concern in the industry.
Chen Chun said that the blockchain should be applied on a large scale in China. If there is no good regulation, no one will dare to take this risk. "There is no good supervision, just like there is no traffic police on the road, or there is no traffic light. It is not acceptable."
Although the current blockchain supervision has achieved initial results, in 2019, the website issued the "Regulations on the Management of Blockchain Information Services". This year, two batches of blockchain information service filing numbers have been announced, but the road to supervision is still very long.
Chen Chun believes that the alliance chain is more suitable for enabling economic construction because its supervision is relatively controllable.
The public chain itself has the characteristics of decentralization, non-tampering, non-deletability, low cost, etc. If it is used to spread harmful information, it will adversely affect the industrial layout and development of blockchain technology, and it will bring very much to the regulatory authorities. Big challenge. But we should also support the development of public chain technology and participate in international competition.
Chen Chun believes that a chain of alliances between a low-trust public chain and a single high-trust private chain is a more appropriate choice. The alliance chain only allows authorized nodes to join the network, while maintaining a certain degree of openness. And traceability features improve system trust issues.
Chen Chun pointed out that there are four major trends in the development of blockchain supervision technology: the first is the tracking and visualization of blockchain nodes, the second is the penetrating supervision technology of the alliance chain, and the third is the active discovery and detection of the public chain. Technology, the fourth is the architecture and standards of the chain of chains.
“The current regulation should be carried out at the technical and institutional levels. Only reliable blockchain technology solutions can be applied, which can be applied in practical applications. We are further researching and providing a regulatory block for the regulatory authorities. Program." Chen Chun said.
