Beijing's data directory blockchain 2.0 went live on January 1. Data directories from Beijing's 80 municipal departments, 16 districts and the economic-technological development areas, and more than 10 social institutions have all been included in the blockchain.

As China's first mega city blockchain infrastructure, the directory manages over 500,000 pieces of directory information and more than 2,700 information systems in real time, supporting the safe sharing of billions of pieces of data across different departments, tiers, fields and subjects.

The upgrade of the directory blockchain is realized via ChainMaker, China's first independent blockchain platform. With high concurrency, low latency and large-scale node networking, the ChainMaker enables a significant uplift of the directory in architecture flexibility, consensus mechanism and data storage. The response time of data query in the blockchain can reach a millisecond level.

In particular, the frame system, technical architecture and core components of the directory blockchain were all self developed, comprehensively guaranteeing system and data security with multiple safety protection techniques. 

The first version of the directory blockchain went into operation in April, 2019. Since then, Beijing has gradually established a new pattern of data management and control, in which the data source can be trusted, scope of authorization is defined, process of circulation is traced, and scenarios and usage are monitored.

The directory blockchain plays an important role in city operation, society management and service for people's livelihood.

Beijing will further explore the trusted circulation of data elements, and the all-process data control and monitoring mechanism of highly coordinated management systems, in order to comprehensively enhance the service of data fusion and sharing between government and enterprises.
