China Internet Network Information Center (CNNIC) has launched research on new domain name resolution architecture and key technologies based on blockchain and other technologies since 2017. Based on this, CNNIC took the lead in cooperating with the Institute of Computing Technology of the Chinese Academy of Sciences, the Computer Network Information Center of the Chinese Academy of Sciences, the National Computer Network and Information Security Management Center, and Sun Yat-Sen University to jointly undertake major national scientific research projects, and proposed a joint governance based on the joint governance chain. New domain name resolution architecture, design of new co-governance algorithm, development of special software and hardware systems, has applied for 15 invention patents, 6 project standards, and produced 14 papers, which initially has the foundation for international promotion and application.

On the morning of July 30, 2021, CNNIC organized a technical meeting to review the research and development progress of the new domain name resolution technology. Zhou Hongren, former executive deputy director of the National Informatization Expert Advisory Committee, Wu Hequan, former vice president of the Chinese Academy of Engineering and academician of the Chinese Academy of Engineering, Qian Hualin, an inductee of the International Internet Hall of Fame and a researcher of the Network Center of the Chinese Academy of Sciences, Xie Gaogang, a researcher of the Network Center of the Chinese Academy of Sciences, and Xu Mingwei, a professor of Tsinghua University Wait for experts to attend the meeting.

Researcher Zeng Yu, director of CNNIC, introduced the overall research and development situation and progress of the project at the technical review meeting. Li Hongtao, chief engineer of CNNIC, gave a presentation and presentation. After questioning and discussion, the experts agreed that the technology research and development work has made good progress. They have studied and proposed a new domain name resolution architecture based on the co-governance chain, designed a new consensus algorithm, developed special software and hardware systems, etc., to achieve the original plan. Milestones. In the process of joint research and development, CNNIC carried out the whole process control, and the organization and management were effective. The experts suggested that on the basis of the existing good work, we should further strengthen technological innovation, actively promote international exchanges and cooperation, and achieve greater scientific research and application results.

In the next step, CNNIC will continue to carry out research on new technologies in the domain name resolution field, give full play to the role of the “national team” in the field of Internet basic resources, shoulder heavy responsibilities, overcome difficulties, strengthen organizational management, promote high-quality project implementation and actively promote international promotion and application .
