The conference was held in the form of "offline & cloud conferencing" and was broadcast live on many domestic media platforms including Peoples Daily Online.

Presient Liu Yunan delivered a speech on behalf of the organizer. He pointed out that to implement China’s deployment on accelerating the development of blockchain technology and industrial innovation,, SIC, China Mobile, China UnionPay and other companies have jointly carried out the top-level design and research and development of the blockchain service network., and the internal testing was launched in last October. At present, the various functions of the blockchain service network have been stabilized, and a number of innovative applications such as charity, material traceability, electronic invoices, copyright protection, and supply chain management have also been spawned. In particular, it has played a proactive role in the prevention and control of COVID-19 this year.

President Liu Yunan said that the commercial launch of the blockchain service network is only the first step to promote the development of the blockchain. Facing the future, we should better serve the national blockchain strategic deployment with greater responsibility, and actively lead the innovation and development of the industry. Firstly, focusing on the current situation. It is necessary to use the blockchain service network to better serve the country in fighting the COVID-19 epidemic, and to escort the recovery of work and production through the multi-party mutual trust mechanism built by the blockchain. Secondly, taking a long-term view. It is necessary to use the blockchain service network to better serve and promote high-quality economic development, and actively explore the innovation of digital economic models. More efforts shall be devoted to promoting the effective match of supply and demand in various industries for the transformation to new driving forces. Thirdly, integrating resources. We should create an industrial ecology and promote the in-depth integration of production, education and research. We shall optimize the underlying architecture, basic capabilities, functional modules, and operation and maintenance system of the blockchain service network to promote the rapid popularization and innovative development of blockchain technology.

Shan Zhiguang, Director-General of the Information and Industrial Development Department and Chairman of the Blockchain Service Network Development Alliance, gave a comprehensive introduction to the commercial situation of the Blockchain Service Network (BSN), and issued the "Chain Service Network Technology White Paper" on behalf of the Blockchain Service Network Development Alliance, and launched the BSN international version of the overseas public test.

At present, BSN has established 128 public city nodes, including 8 overseas nodes and mainstream cloud service providers such as China Mobile, China Telecom, China Unicom, Baidu Cloud, Google Cloud and Microsoft Cloud. It has built a global public infrastructure network at the bottom of the blockchain, and has established a five-level security mechanism to ensure the data security of the entire network and the entire chain. BSN reduces costs of the development, deployment, operation and maintenance, intercommunication and supervision in blockchain applications.In the future, BSN will continue to promote technological innovation and performance optimization to create a "new infrastructure" for the blockchain. BNS provides a multi-industry basic resource environment based on blockchain technology, and improves the blockchain industry ecology. It lays a solid foundation for the development of smart cities and digital economy.
