Since the end of January, the "war epidemic" for the prevention and control of new crown pneumonia has brought a "big test" to the entire society, and has also posed severe challenges to the operation of enterprises in all walks of life. However, "danger" and "opportunity" always accompany each other. Industrial recovery after the epidemic may also be an opportunity for industrial transformation and upgrading.

In 2003, the SARS epidemic accelerated the process of popularization and commercialization of the Internet. That year, products and companies such as Taobao and JD.com that had a profound impact on China's digital economy were born. From a historical perspective, this year's new crown pneumonia epidemic is likely to be a historic "turning point" for the transformation and upgrading of many industries. This change is of great significance. It is not only a stopgap measure to deal with the epidemic, but also an important opportunity to accelerate the digital transformation of various industries and promote the transformation of corporate organization.

This series will focus on new digital technologies such as artificial intelligence, big data, blockchain, 5G, and the Internet of Things, and introduce and analyze their application principles and cases in epidemic prevention and control. The first article will focus on the emerging blockchain technology.

For the principle of this technology, please refer to the series of articles:

Blockchain three minutes a day: What are the characteristics of blockchain?

The eighteenth collective meeting of the Political Bureau of the Central Committee on October 25, 2019 emphasized: “The integrated application of blockchain technology plays an important role in new technological innovation and industrial transformation. We must use blockchain as a core technology. An important breakthrough for independent innovation, clarify the main direction, increase investment, focus on conquering a number of key core technologies, and accelerate the development of blockchain technology and industrial innovation.” This put forward new requirements for the core positioning and direction of blockchain technology, and China’s digital Economic development and industrial innovation practice .

Blockchain technology was born at the end of 2008. Its main feature is a distributed encrypted data storage method, also known as distributed ledger. Blockchain technology uses a block-chain structure to verify and store data, uses consensus algorithms to generate and update data, uses cryptography to ensure data and ownership security, and realizes collaborative data calculation through programmable script codes. In recent years, by virtue of its unique trust transfer mechanism, blockchain has gradually demonstrated outstanding advantages such as credibility of business data, equalization of participants, and multidimensional supervision methods. It is helpful to realize the credible sharing of business data in all walks of life, accelerate the multi-party collaboration of participating entities, and achieve regulatory penetration management, which contains the potential to accelerate my country's digital transformation and stimulate the development of the digital economy.

On the basis of these technical features and advantages, in this anti-epidemic action across the country, Blockchain has played an important role in charity, community epidemic prevention, and resumption of work and production.

First of all, the blockchain has the characteristics of non-tampering, multi-party synchronization, and information transparency, which highly matches the needs of the charity industry. It can even be said that charity is a natural scenario for blockchain applications. At present, there are also a series of actual cases in the application of blockchain in this field. For example, after the outbreak of the epidemic, Alipay’s “epidemic prevention material information service platform”, China’s Xiong’an Group, and the “blockchain charity donation management traceability platform” initiated by Qulian Technology, and the “emergency material management” initiated by Zhongbang Bank and Kingsoft Cloud A batch of emerging “blockchain + charity donation” charity platforms such as “System” are quickly applied. Blockchain company ICreativeStore has launched a special psychological consulting service based on its unique alliance chain technology platform, using blockchain technology to link people who need psychological assistance, volunteers and physicians who provide services, and has achieved remarkable results. In response to the urgent needs of community management, everiToken quickly iterates and publishes "access", which records and uploads the access information of community residents, avoiding manual errors and omissions.

In the future, as the entire society's blockchain infrastructure is further improved, blockchain will bring greater changes to charity. The public welfare platform based on blockchain + smart contract can pre-set rules for the use of donations, materials, and services to realize automatic allocation of funds and ensure that the special funds are used exclusively. At the same time, the donations can be tracked on the chain to understand the ultimate destination of each donation, reducing the possibility of fraud by organizations and individuals. Charity organizations will complete their role changes amid changes, gradually build a transparent, efficient, and global collaborative public welfare system, and become a sample of blockchain distributed organization.

Second, in the process of preventing and controlling the epidemic, blockchain technology played an important role in the tracking of personnel flow information and community governance, making community epidemic prevention more accurate and efficient. Blockchain technology uploads the data to the epidemic prevention and control coordination system, which can realize secure encryption, improve the efficiency and security of data acquisition, and also make the data immutable and enhance the credibility of the data. The data in the system can be traced throughout the entire process, providing credible data support for epidemic prevention and control and decision-making assistance for government departments to implement precise policies.

For example, in Jing'an District, Shanghai, community workers can automatically generate a registration information form for returning people to Shanghai with a single click of the mouse. Through the "Smart Pro Second" system developed by Tongji University based on blockchain technology, the complex work of community workers has become orderly. Mask reservations, registration back to Shanghai, health check-in, visitor registration, community care services, etc. for more than 20 communities, 688 merchants and more than 20,000 people can all be completed through this system. In Nansha District, Guangzhou City, Guangdong Province, the epidemic prevention and control coordination system aggregates epidemic data, resource scheduling, and key personnel data. Through the epidemic prevention and control command center, epidemic prevention material management, enterprise resumption management, epidemic prevention information reporting and other modules, visualized management is realized, so that key information such as materials, beds, transportation, and corporate economy can quickly support decision-making.

In addition, the Ministry of Industry and Information Technology recently issued a notice to deploy a new generation of information technology to support services for epidemic prevention and control and the resumption of work and production of enterprises. Among them, blockchain has also played an active role in helping companies resume work and production.

The prerequisite for resumption of work is effective management of personnel. One of the most critical is the "penetrating" real-time data management capability. An important function of blockchain is to help achieve penetrating supervision and refined governance. A few days ago, China Unicom Research Institute, Jiangxi Unicom and Jiangxi Industrial Internet Branch have developed the country's first "blockchain-based enterprise resumption and production filing platform". The platform is based on the advantages of block chain technology such as anti-tampering and multi-node synchronization. It solves the problems of remote online reporting, cross-regional city and cross-department rapid synchronization, and the security and credibility of filing data, avoiding the gathering of on-site personnel, improving the efficiency of filing, and helping the government The resumption of work and production filing has relieved the worries.

Finally, the financial support needs of enterprises that resume work can also be realized through blockchain. The implementation of blockchain financial application scenarios will help alleviate the financing problems of small and micro enterprises. On 7 February, Beijing Haidian District launched a blockchain-based supply chain financial service platform for small and medium-sized enterprises, and granted a 50% discount to the benchmark interest rate for companies that carry out financing businesses. On 14 February, the platform completed the first right confirmation and loan after its launch, helping a company that supports the new crown pneumonia epidemic and guarantees school distance education to obtain a loan of 720,000 yuan and obtain the first loan of 440,000 yuan.

However, while applying advanced scientific and technological means, we must also consider new legal relationships and legal issues that arise, and adjust relevant legal systems in a timely manner. Let advanced technological means more adapt to the requirements of the times. After a major emergency, what personal data can be collected and disclosed, and to what extent? And other details. These still lack more authoritative regulations and explanations.

In addition, data protection such as health information and genetic information are also issues that need to be focused on in the future. In response to some of the problems exposed by the new crown pneumonia, it is necessary to build a better linkage system and mechanism in the future. Various departments cooperate with each other and give full play to the role of advanced scientific and technological means. For example, if the data on the chain involves personal information, privacy protection technology should be used carefully. Operators can have location information. But in principle, only group information can be analyzed, and individual data cannot be tracked. Moreover, these information can be used only after a higher level of approval.

Generally speaking, in the process of disaster prevention and emergency, information can be shared and exchanged in a timely and effective manner, which is very effective and important for the prevention and control of disasters or emergencies. The features contained in the blockchain have natural advantages for information regulation, collaboration and mutual assistance, and trust establishment in disaster prevention and emergency response. Therefore, the country may place the blockchain-based disaster prevention and emergency command system in an important position in the process of laying out national IT infrastructure.

With the active advancement of the entire society toward the digital economy and new infrastructure, blockchain technology will exert great potential and value in more application fields and scenarios. It is foreseeable that after the full resumption of work, blockchain technology will further promote the accelerated transformation and upgrading of various industries.
