On December 14, 2020, Xiongan blockchain underlying system 1.0 was released. This means that the first domestic city-level blockchain underlying operating system has been developed and put into use. Li Jun pointed out that in the past, the application of blockchain technology stayed at the level of "blockchain + industry". However, the application space of blockchain technology is far more than that. It is the first in China to study blockchain as a city-level digital infrastructure.

Xiong'an New Area's "Multi-Measurement Integration" information management system will closely integrate blockchain and other technologies: Xiong'an New Area recently launched the "Multi-Measurement Integration" information management system project to improve the quality and efficiency of surveying and mapping services for engineering construction projects in the New Area. The relevant person in charge of the Xiongan New Area Management Committee stated that the "multi-measurement integration" information management system will be based on the latest technology architecture in the industry, closely combined with new-generation information technologies such as big data, cloud computing, Internet of Things, and blockchain, and insist on innovation and leadership. , to create a better information system, to serve the planning and construction of the new district, and to lay the foundation for the next step of the urban operation of the new district.

Li Jun introduced that the Xiongan blockchain underlying system 1.0 is independently controllable, adopts independent intellectual property rights technology, and builds a new blockchain underlying architecture that integrates "core chain + application chain" multi-layer chain network. Innovative breakthroughs have been achieved in pain points such as blockchain collaboration, trusted data exchange, and security.

On the underlying technology platform of the blockchain, many blockchain basic public services such as digital identity and digital credit can be carried out, providing an elastic and flexible environment for blockchain technology research, urban applications, industry applications, etc., and promoting Build a rich metropolitan blockchain ecosystem.

News | Xiong'an New Area Management Committee has officially launched the "Xiong'an Expropriation, Demolition, Resettlement Fund Management Block Chain Platform": According to the Economic Daily, the Xiongan New Area Management Committee has officially launched the "Xiong'an Expropriation, Demolition, Resettlement Fund Management Block Chain Platform" Blockchain platform", which will apply ICBC's blockchain technology to realize the whole-process on-chain management of the original archives of expropriation and demolition and the penetrating payment of funds. The relevant person in charge of ICBC said that the bank is continuously expanding the "blockchain +" platform, and the project fund management system developed by it has been used in most projects of Xiong'an Group and its subsidiaries, including flood interception canal, Tanghe pollution control, spring And the autumn afforestation project has covered more than 300 participating enterprises and more than 5,000 participating personnel in the new area.

In fact, blockchain applications are already a reality. In August 2018, Xiongan launched the first construction project fund management platform based on blockchain technology in China - the engineering construction blockchain information management system. All funding applications, approvals, and allocations related to project construction in Xiong'an New Area are completed through the blockchain platform. According to Li Jun, the platform has served thousands of companies, 196 engineering projects, and 140,000 migrant workers, with a cumulative allocation of about 20 billion yuan.

Through this platform, all contracts, tickets, etc. between the enterprise and the general contractor, between the general contractor and the subcontractor, and between the subcontractor and the construction unit are uploaded to the blockchain system, and all actions will be recorded. Imprint, subject to supervision. In Li Jun's view, the platform can actually protect the interests of migrant workers. "If there is any link that defaults on or deducts the wages of migrant workers, everyone will know it clearly."

"Transparent, open, and non-tamperable, the blockchain makes data credible and increases the means of supervision. After it is truly formed, it will bring changes to the system, mechanism, and process." Li Jun said.

Combine resources to carry out special research

As a public and open experimental platform, the Xiongan Blockchain Laboratory brings together resources, projects and talents from all aspects to carry out special research on basic key technologies to provide support for the expansion of the application of blockchain in the new area.

According to reports, the laboratory has set up three key research directions: standards and norms research, basic frontier and key technology research, industrial operation mode and application demonstration, and established three long-term goals. First, become a new highland for blockchain research and application. In the field of blockchain technology, blockchain applications, and the integration of blockchain and other smart technologies, Xiongan Blockchain Lab has taken the lead and surpassed. Second, become an open frontier innovation base. The Xiongan Blockchain Laboratory is open to the whole society and the world; it is open to innovative talents, innovative ideas, and innovative practices. Third, explore a new model of laboratory economy, develop technological services such as business incubation, technology transfer and transformation, technical consultation, policy consultation, comprehensive application of intellectual property rights, testing, evaluation and certification, and give full play to the knowledge spillover effect.

Li Jun introduced that before the establishment of the laboratory on March 31 last year, they had done a lot of exploration in blockchain technology and achieved initial results. "Including issues such as capacity, performance, and security, and how to unify standards and specifications to form a joint force."

In the early application of the consortium chain, performance was sacrificed to obtain credibility and security. However, with the deepening of the application, a solution to balance performance and security and credibility has been gradually explored. "One solution is to adjust and layer the software architecture." Li Jun said, "Not all applications require extremely high performance. For example, application A may be fast, while application B may be safe but not so fast, so A and B should be layered." This layered architecture has been applied to the underlying system 1.0 of the Xiongan blockchain.

As a digital infrastructure, Xiongan needs to realize the interconnection of blockchain. "This requires construction in accordance with certain standards and specifications, just like in the Internet era, expanding from local area network to metropolitan area network, based on commonly recognized standard protocols, and further expanding to wide area network."

Li Jun introduced that the Xiongan Blockchain Laboratory has established cooperation with relevant domestic blockchain standardization units to research and formulate relevant standards. "Until last year, we have made three blockchain-related local standards, and we will continue to increase this year."

Exploring the establishment of a digital identity system

Using blockchain and other technologies, Xiongan is exploring the establishment of a digital identity system. In January 2019, the "Xiongan New Area Engineering Construction Project Tendering and Bidding Management Measures (Trial)" proposed to build an enterprise and individual integrity evaluation system based on big data and blockchain, and publish the credit information and credit information of all parties in real time. evaluation index. In terms of information sharing and new technology application, establish a network trusted identity authentication system and license database based on blockchain technology, and project information, enterprise information, personnel information, file transfer, capital payment and other information are encrypted and backed up through blockchain technology.

Li Jun revealed that the digital identity may be put out for trial by the end of this year. The comprehensive application of blockchain technology and privacy computing technology can greatly improve the situation of excessive use of personal privacy information.

"Digital identity is expanded based on the legal identity of citizens, and different identities can be expanded in different APPs. In this way, APP does not need to retrieve legal identity information, only the corresponding extended information is enough. Now citizens Personal information is exposed seriously. For example, to register and log in to some apps, you need to upload the front and back of your ID card, upload your driver’s license, etc., and these apps only need to know whether the user can actually drive. The digital identity system can solve these problems to a certain extent.”

In addition to personal digital identities, trees in Xiong'an New Area have long had "ID cards". In November 2017, the first tree planted in the "Millennium Xiulin" in Xiong'an had its own "ID card", which recorded the whole process of cultivation, inspection, management and pruning.
