What this article shares with you is about how to design and analyze the government affairs platform based on block chain. The editor thinks it is very practical, so I share it with you for study. I hope you can get something after reading this article. Let's take a look at it with the editor.

Digital government is an important carrier to promote the refinement and intelligence of public service and social governance. Recently, plans have been issued one after another all over the country to actively promote the application of block chain to the government system.

I. background

At present, the global scientific and technological innovation has entered an unprecedented intensive and active period, and the new generation of information technology represented by block chain has accelerated the breakthrough and application, which has been extended to many fields, such as digital finance, Internet of things, intelligent manufacturing, supply chain management, digital assets trading and so on. Blockchain has created a new computing method and cooperation mode of building trust at low cost in an untrusted competitive environment. With its unique trust-building mechanism, it has realized penetrating supervision and trust transmission step by step, and is currently extending to the vertical field. There is great potential for change. The development foundation of the field of block chain in China is good, and it has shown great potential and value in promoting digital government, real economy, people's livelihood, smart city and interconnection. Governments all over the country are seizing the opportunity of the development of blockchain technology to accelerate the development of blockchain technology and industrial innovation.

II. Current situation

Digital government is an important carrier to promote the refinement and intelligence of public service and social governance. Recently, plans have been issued one after another across the country to actively promote the application of blockchain to the government system. "Government chain" is conducive to the digital government to a higher level, but the government block chain to play a role, cross-departmental, cross-domain connectivity is still the key. At present, the "chain of government affairs" is in a period of rapid development, and standardization and guidance are relatively lagging behind. In the process of development and construction, we have also encountered some problems:

1. The standards and norms are not unified and the infrastructure is not perfect:

Lack of top-level design, no unified data standard and interface standard

Block chain government applications vary in security, stability, performance, etc.

The design and function are not closed-loop, not systematic, and relatively random. Different underlying architectures and different data structures lead to the lack of interconnection between systems, difficult business coordination, poor openness of basic capabilities, and difficult to meet the needs of future development.

2. The business is complicated and it is difficult to guarantee the information security.

The business content and business logic of government services are complex, the application of block chain is difficult to meet the requirements of strong security protection, and risks continue to accumulate.

Different government affairs involve different levels of authority.

Government services involve large groups and a wide range of areas, and security accidents will have a great negative impact.

3. It is difficult to share information, and it is hard to avoid repeated construction.

Generally speaking, the running environment is built separately for different applications.

The hardware can not be fully utilized in the process of use, and the components can not be reused, resulting in a waste of infrastructure.

Lack of unified management of chain and basic resources, it is difficult to share data between block chain applications, and it is easy to form new isolated islands of information.

The hardware and software infrastructure of blockchain is easy to lead to repeated investment and construction.

4. there is a shortage of professionals in the block chain, and the cost of operation and maintenance is high.

Technical personnel are scarce, and it is reported that there will be a shortage of 5 million talents in the next two years.

There is no professional examination and certification for the skills of operation and maintenance personnel, and the manpower cost is high.

It is easy to cause artificial or non-man-made business stagnation and then affect the service and experience of government functional departments.

III. Solutions

In order to solve the above problems, Huawei proposed a unified administrative blockchain infrastructure (UGBaaS) solution for overall design and standards, to achieve mutual trust among departments, data co-governance, service sharing, and to build a safe, reliable and efficient blockchain infrastructure platform. The bottom layer realizes software and hardware sharing and co-governance, vertical information transparency, horizontal data interconnection, reducing the cost of application construction, management and maintenance of government block chain, and improving the coordination level, supervision ability and service experience of government business. we will speed up the reform and construction of digital government. The architecture diagram is as follows:

The system includes the bottom block chain, the bottom block chain standard nanotube interface, the bottom block chain management, the unified public service components and so on.

1. Underlying block chain

The underlying blockchain platform provides basic data storage capabilities, network communication capabilities, consensus mechanisms, virtual machines, editable intelligent contracts, software and hardware resource operation and maintenance monitoring, SDK interfaces and other basic capabilities or components.

The underlying block link should meet the following requirements:

A) should be audited by the district public data management department

B) it should meet the requirements of intensification and compatibility and can be adapted to a variety of underlying cloud platforms

C) shall meet the requirements of the underlying block chain platform nanotube interface standard.

2. The standard nanotube interface of the underlying block chain

The underlying block chain should be connected to the government block chain platform through the standard nanotube interface, and the standard nanotube interface should include unified security interface, unified operation interface, unified resource interface, unified cross-chain interface and unified supervision interface.

Unified security interface: supports unified identity authentication and authentication for different underlying block chains.

Unified operation interface: supports unified operation monitoring, checking alliance / node operation status, alliance / node resource utilization, upwinding business analysis, and so on.

Unified resource interface: supports unified block chain resource management, including the management of alliance chain, application chain, node, intelligent contract, etc.

Unified cross-chain interface: supports cross-chain mutual authentication, cross-chain transactions and so on.

Unified regulatory interface: support unified audit log, sensitive word audit, etc.

Feature function interface: in addition to the standard nano-management interface, the government block chain platform should also provide relevant feature function interfaces for upper-level applications to call to support personalized management and services.
