New crown virus epidemic war, what can the blockchain do?

Original: People's Forum Network

The economic loss and social impact caused by the new coronavirus epidemic are still continuing. How to overcome the epidemic situation and restore the normal production and living order of society as soon as possible? In addition to the expected macro-control, effective supervision, and the mobilization of medical staff to the front line, accelerated application of new technologies to help outbreak surveillance, the deployment of medical supplies and the effective development of public welfare and charity work have also become new important research topics. .

In October 2019, the General Secretary of the CPC Central Committee Xi Jinping emphasized during the eighteenth collective study of the Political Bureau of the Central Committee that the integrated application of blockchain technology played an important role in new technological innovations and industrial changes. The General Secretary pointed out that it is necessary to take blockchain as an important breakthrough in independent innovation of core technology, clarify the main attack direction, increase investment, focus on overcoming a number of key core technologies, and accelerate the development of blockchain technology and industrial innovation. At present, the application of blockchain technology has extended to many fields such as digital finance, the Internet of Things, intelligent manufacturing, supply chain management, and digital asset trading. Major countries in the world are accelerating the development of blockchain technology.

Blockchain technology has many characteristics and advantages such as "distributed", "decentralization", "immutable", "transparency", etc. In this epidemic, blockchain technology is not only used in charity donation tracking, epidemic tracking, and There are applications in medical data management, medical supplies, and drug traceability, and it is conducive to the accurate management and dynamic monitoring of the movement of community personnel in the process of community epidemic prevention and control. Blockchain technology has natural advantages in issues such as information trust and collaboration across agencies and regions, and breaking information silos in the medical field.

Blockchain + charity: make data more transparent, private and more secure

Philanthropy is a natural multi-participation field. Among them, non-profit organizations are faced with the problem of efficiently and fairly distributing huge amounts of front-line materials; donors have difficulty making point-to-point accurate donations to recipients and cannot understand every donation or material Where the public lacks effective supervision, it can easily lead to a lack of trust.

Blockchain technology can establish a set of open, transparent, and traceable systems in which donors and recipients can query the beginning and end of each payment. The information can include the number of releases, as well as the use methods, implemented at each link. When blockchain technology puts all donation information on the chain, such a system can effectively reduce differences and improve efficiency. One of the core values ​​of blockchain technology is its distributed structure, which can improve efficiency and simplify processes. As far as the epidemic is concerned, blockchain technology makes the donated materials clearer and clearer, and at the same time it helps to increase public participation.

On the blockchain system platform established by the well-known blockchain technology research and development company Findora, data will be encrypted for transmission and will not be abused by anyone. For example, the Red Cross can guarantee its own transparency and openness. At the same time, donors and recipients are protected by privacy. When third parties or the public need to review, they can also pass technical audit data such as zero-knowledge proof. Will expose privacy. Among them, the audit tool allows donors to retrieve private data, and even if they are low-key and doing good deeds, they can also query their own confidential data at any time.

Blockchain + epidemic warning: make epidemic monitoring and warning more timely

It is understood that as early as April 2008, China ran an automatic national early warning system for infectious diseases in 31 provinces (municipalities, autonomous regions) throughout the country, established an automatic early warning and response mechanism, and realized automatic analysis, time and space analysis of 39 infectious disease surveillance data. Aggregated real-time identification, early warning signal sending, and real-time tracking of response results. Reporting methods have gradually evolved from traditional manual reporting to information and IT reporting modes.

Disease prevention and control centers at all levels can register nodes in the blockchain system, flatten the traditional "infectious disease reporting system" vertical reporting model, and speed up early warning for epidemic information transmission. When a single hospital finds a suspected epidemic case, it uploads the information to the chain and broadcasts it on the entire network. Due to the open and transparent nature of the blockchain, the data cannot be tampered with and traceable, each node can obtain accurate reporting information at the first time. , Reduce the time of information dissemination and the possibility of misinformation. Through a unified information early-warning platform, the epidemic prevention center can achieve real-time acquisition and real-time prevention of epidemic situations, and overcome the lag of traditional epidemic situations.

Blockchain + trip monitoring: make personnel isolation more efficient

According to statistics, as of mid-February, nearly 300 million passengers were sent across the country after the holiday. Due to the epidemic, only one-sixth of the Spring Festival passenger flow. However, the greater challenge to traffic caused by this epidemic is the incomplete vehicle management during the epidemic, and a large number of passenger vehicles were stranded outside the country. How to effectively identify vehicles and monitor the movement of people in various places has become a difficult point.

In the era of the Internet of Everything, mobile phones, apps, bus cards, etc. are collecting people's privacy data, which can easily determine a person's itinerary, but the issue of privacy leakage may be involved in the process of integrating data.

How to protect the privacy of individuals, while also allowing people to report their schedules voluntarily and truthfully, so as to ensure that people who are suspected to be infected can be found efficiently and accurately?

In response to this problem, through the technology of blockchain and cryptography, zero-knowledge proof, etc., it is possible to screen and compare the intersection of each person and the confirmed patient's itinerary, while ensuring the security of the user's personal privacy data. It is understood that the use of blockchain certificate to upload the user's itinerary information can also prevent the information from being tampered with. In the face of shortage of medical resources, some people can effectively avoid forging personal trips in exchange for priority. Through the combination of cryptography technology and blockchain, the existing "confirmed patient ride query" can be extended to a wider range and more channels.

With the cooperation of big data and artificial intelligence, blockchain technology provides effective solutions for the precise management of vehicles and personnel through multi-region data sharing, and achieves effective monitoring of epidemic prevention and control.

Blockchain + medical data sharing: making epidemic prevention and control more transparent

At the beginning of the January epidemic, due to the slow data flow between the hospitals, the patient data statistics were not timely, and the judgment and treatment of the epidemic situation had a great impact. The typical data island problem appeared in each hospital medical institution. The use of blockchain technology to establish a highly efficient shared data network will greatly improve the statistical efficiency of the epidemic. By sharing the data of treating patients, it can help medical institutions to complement each other's treatment capabilities and better achieve treatment tasks.

Medical data is directly related to our lives, health and personal property, so its privacy, security and accuracy are extremely important. Combining blockchain with cutting-edge cryptography such as zero-knowledge proof can ensure the privacy of the medical data sharing platform while effectively protecting the original characteristics of the blockchain.

In the supply chain management of medicines and other medical supplies, blockchain technology will also play a huge role. From the production source of the drug to the final arrival of the drug, the blockchain technology can realize the entire process monitoring by establishing a completely transparent database, and the data cannot be tampered with. In this process, the circulation of each step of the drug will be recorded in detail, effectively ensuring the safety of medical supplies.

It has been more than ten years since the birth of the blockchain, and the application practice of the blockchain in public welfare, medical and other public utilities has just begun. In this battle against the new crown epidemic, the huge potential of blockchain technology has begun to emerge. Although some of the technologies mentioned in the article have not been fully applied in our lives, they have already shown us their role in social public utilities Hope in exerting power. We can expect that with the maturity of blockchain technology, the rational and effective use of blockchain technology will help prevent viruses, rebuild social life, and provide better services for future public services.
