| 联盟链技术是我国区块链发展和应用的主阵地.传统联盟链应用存在底层技术平台异构、应用技术门槛高、成链成本大、运维监管难等瓶颈问题，限制了区块链技术与应用发展.提出一种区块链公用基础设施——区块链服务网络（blockchain-based service network，BSN）的构建机理，阐述BSN的技术架构和实现机制.BSN已于2020年4月在中国正式商用，能够显著降低区块链开发、部署、运维、互通和监管成本，有利于区块链技术向企业、政府、行业等领域推广应用，为我国新型智慧城市建设和数字经济发展提供了可信可控的公用基础设施和服务载体. |

| Abstract: |
| Consortium blockchain technology is the main position of China’s blockchain development and application. The traditional consortium blockchain application has some bottlenecks, such as heterogeneous underlying technology platform, high application technology threshold, high cost of chain formation, and difficult operation and maintenance supervision, which restrict the development of blockchain technology and application. This study proposes the construction mechanism of a public infrastructure of blockchain, named as blockchain-based service network (BSN), and expounds on the technical architecture and implementation of BSN. The BSN has become a commercial platform in China since April 2020. It can reduce the cost of blockchain development, deployment, operation and maintenance, interaction, and supervision. BSN is conducive to the promotion and application of blockchain technology to enterprises, governments, industries, and other fields, and will provide reliable and controllable public infrastructure for the construction of innovative smart cities and the development of digital economy in China. |
