What are the characteristics of the six blockchain projects selected this time? Liu Quan said that overall, the six projects selected this time focus on the two major directions of network security protection and new technology and new application security. The content of the project is out of the picture, focusing on the three areas of blockchain industry application, cryptographic algorithms and security supervision.
On April 18, the official website of the Ministry of Industry and Information Technology issued a notice, in accordance with the Notice of the General Office of the Ministry of Industry and Information Technology on the Implementation of the Pilot Project for the Application of Network Security Technology Pilot Project (the Ministry of Industry and Information Technology Network  No. 36) After expert review, 101 pilot projects for network security technology application were selected and publicized.
"Daily Economic News" reporters browsed the "Network Security Technology Application Pilot Demonstration Project Publicity List" and found that there are 101 pilot demonstration projects, including 6 blockchain projects, respectively, No. 21, for the power "Internet +" business Trusted blockchain public service platform; No. 30, blockchain-based electronic invoicing system; No. 64, research and demonstration application of the underlying platform of the alliance blockchain based on SM series password; No. 65, based on the alliance blockchain Sanfang Electronic Data Security Platform; No. 81, Government Affairs Alliance Blockchain Government Information Trusted Delivery Platform; No. 82, a security risk monitoring platform for the blockchain industry. The overall proportion of blockchain projects in the region has exceeded 5% (6/101).

What are the characteristics of the six major blockchain projects selected this time? What are the advantages of blockchain in network security applications? What are the challenges of large-scale application of blockchain? The reporter of "Daily Economic News" interviewed Liu Quan, director of the CCID Network Security Research Institute of the Ministry of Industry and Information Technology and dean of the CCID Block Research Institute.
What are the characteristics of the six blockchain projects selected this time? Liu Quan said that overall, the six projects selected this time focus on the two major directions of network security protection and new technology and new application security. The content of the project is out of the picture, focusing on the three areas of blockchain industry application, cryptographic algorithm and security supervision, and innovatively using blockchain technology to build a network security credible system. In terms of application scenarios, the focus is on energy and power, electronic invoicing, data preservation, and government affairs. The use of blockchain technology to achieve multi-agent information security sharing, data depositing, and network credibility, to achieve cost reduction, efficiency, security and stability In the aspect of cryptographic algorithm, relying on domestic cryptographic algorithm to reconstruct the underlying framework of blockchain, and focus on creating demonstration applications to improve blockchain security and autonomous controllability; in the aspect of security supervision, actively launch industry-oriented security risk monitoring Platform to improve the blockchain supervision system.
What are the advantages of blockchain in network security applications? Liu Quan said that blockchain technology can realize a network security trust system based on "technology." First, the use of identity verification mechanism to protect edge devices from "infection", especially in improving the security of Internet of Things, industrial Internet and smart cities, security and other terminal equipment; second, the irreversible distribution of blockchain construction The book can improve system confidentiality through encryption, permission control and other technologies to ensure data security, integrity and continuity. Third, privacy protection, blockchain technology can maximize data privacy of individuals and users, and prevent data leakage. And tampering; Fourth, the combination with third-party electronic certificate authority can improve system supervision and standardize node user behavior; Fifth, support a more secure DNS architecture, register and resolve domain names through blockchain technology, and prevent large-scale "Bodynet" intrusion.
What challenges will the large-scale application of the blockchain face in the future? Liu Quan believes that, first of all, the large-scale application of blockchain faces two major problems of performance and security. From the perspective of distributed system theory, performance and security cannot be combined, but how can it be improved in the case of maximum security? The blockchain performance metrics make it more suitable for specific application scenarios and still recognized as a technical problem in the industry. Secondly, the operation cost of the blockchain enterprises and the cost of talents are relatively high. The market demand has not entered an outbreak period. The effect of the blockchain application case needs further verification, and the large-scale application is still immature. Finally, the application of blockchain, especially the application of the alliance chain, requires multi-party coordination across enterprises and systems, and achieves a consensus. Compared with the construction of centralized application system, it has increased a lot of difficulty, which leads to the difficulty of landing some good application scenarios and long cycle, and the project construction and promotion are lagging behind.
