A war on epidemic prevention has also exposed various social problems.

In many public opinion storms, the whereabouts of donated materials in Hubei, the publicity of money information, the management of medical materials in Hubei, as well as false reports of grass-roots epidemic tracking information, and so on, have affected the hearts of many folk wild governors.

It also shows how important it is to build one or more transparent, traceable data networks.

Smart friends may ask, let many parties reach trust and consensus, this is not the strength of the blockchain?

However, during the critical period when AI and 5G joined forces to help fight the epidemic, while we saw a sharp rise in bitcoin due to the risk aversion of the epidemic, we saw that the blockchain technology itself, which was supported by the leaders, slightly overshadowed the application of epidemic prevention.

This can not help but remind people of the chaos of "currency entering and retreating" at the beginning of the industry, and what can the block chain with great potential do to fight the epidemic?

What are the possible opportunities for blockchain epidemic prevention?

With regard to the technical principle of blockchain, we have done a lot of popular science before.

To put it simply, the data on each block is encrypted by the hashing algorithm, and any changes will be found inconsistent by the participants, which constitutes that it is unalterable and accessible to everyone, which helps to form a transparent and clear supervision chain; second, the blocks are connected with each other to form a transparent traceability chain.

So, why can the above characteristics be used in this epidemic prevention work?

The first is to maintain the transparency of large-scale material management. We know that this epidemic prevention work has gathered many social charitable donations, but the information among donors, charitable platforms and payees is asymmetric. How to manage these materials efficiently, timely and credibly, and to achieve the mutual trust of many people, the account management of the management department must be clearly searchable, documented, irrevocable and irrevocable.

In order to avoid the black box in the process, there is even an incident in which the goods are delivered directly to the terminal by helicopter. Thus, if you want to reach a consensus under the premise of multi-party supervision, using the distributed ledger of the blockchain is certainly more helpful for the public to build trust.

In addition, it can also make material management more efficient. In this epidemic prevention war, taking Hubei, where the situation is the most severe, for example, the allocation of materials involves the synchronous coordination of many hospitals in the province, while the central management of unified disposal of materials is obviously prone to the situation of out-of-sync information and low efficiency of updating. I don't know the actual loss of each hospital. At this time, if you want to cooperate with multiple parties at the same time, a multi-party bookkeeping "general ledger system" can obviously help material managers to grasp the situation more effectively and operate efficiently.

In addition to material management and disposal, the monitoring and collection of disease data involves the cooperative work of many countries, provinces and communities. How to make multi-party data flow and share safely under the premise of privacy protection, so as to provide support for epidemic prevention? the block chain algorithm based on secure multi-party computing is naturally the first choice.

In fact, as early as 2018, in response to the Ebola epidemic, Jia Bainga Kangbai, a tropical infectious disease scholar at the University of Munich in Germany, created a blockchain database system SERIS to track the epidemic.

Through SERIS, confirmed and suspected cases of Ebola can be marked and summarized over the Internet. At the same time, it aggregates census data, traffic data and Ebola vaccine production reserve data to provide decision-making basis for epidemic prevention and control.

A COVID-19, how to let the block chain land "robbed"

In fact, in the process of epidemic prevention, we have also seen the role of blockchain.

For example, block chain + charity, does not need platform human intervention, the system automatically marked with a "time stamp", can help material donations to achieve transparent management and traceability.

On February 7, Alipay launched the epidemic prevention material information service platform, which uses ant block chain technology to examine and verify the information of material demand, supply, transportation and other links, and store certificates on the chain, leaving no links in the black box.

On Feb. 10, the charitable donation traceability platform "good trace", which was cooperated by fun chain Technology and China Xiongan Group Digital City Company, was also officially launched to solve the trust problem of public welfare material donation. at present, more than 745.78 million yuan of public welfare donation funds have been deposited.

For example, the block chain is combined with the urban brain to provide coordinated management of epidemic prevention and control.

As early as February 2, the epidemic prevention and control collaborative system was launched in Nansha District of Guangzhou City. On the basis of the original "Nansha City brain" system, the epidemic situation data, resource scheduling, key concern personnel and other data were collected together. Through the epidemic prevention and control command center, epidemic prevention material management, enterprise rework management, epidemic protection information reporting and other modules to achieve visual management. So that materials, beds, transportation, enterprise economy and other key information can quickly support decision-making.

The next day, Acoer, an American blockchain software technology company, also created an epidemic data visualization tool HashLog with the help of Hedera Hashgraph common chain, which collected data from the World Health Organization and various countries and regions' centers for disease control, and displayed novel coronavirus's data and trends in real time.

At the same time, the application of block chain has also sunk to the street community management. For example, the "Wisdom Primary two" platform in Linfen Street, Jing'an District, Shanghai, through block technology, has realized mask booking for more than 20 communities, 688 merchants and more than 20,000 person-times, registration back to Shanghai, health clocking in, visitor registration, community care services, etc., which not only enables a lot of work to run without contact, but also enables electronic certificate storage to have evidence to follow.

Since blockchain is not sitting on the sidelines, why should we say that it is tarnished? Mainly compared with the application scale and maturity of other technologies:

On the one hand, unlike the innovative blowout situation of artificial intelligence and big data blooming everywhere, from vaccine research and development to information investigation, the technical application of blockchain is still limited to individual cases and more stays at the level of trend. especially represented by leading enterprises and areas with a high degree of wisdom, the actual effect has not yet been fully demonstrated.

On the other hand, the participation of blockchain epidemic prevention is also relatively limited, which is different from the grand occasion that artificial intelligence projects quickly call on global developers to participate after opening up on github, the participation of both enterprises and developers is relatively limited, due to various limitations of technology, computing power and cost, it is also difficult to apply on a large scale in reality in the short term.

Therefore, although the blockchain presents a more orderly, transparent, mutual trust and benign social management potential, it still fails to play its due role in the current intensive anti-epidemic process. Is there a feeling that "the heroes of all ages have shed tears over this"?

In addition to technology, the "humanistic threshold" of block chain epidemic prevention

Of course, the blockchain is tarnished, and the limitations of the technology itself are not the core issue. The main contradiction is:

First, the acceptance of blockchain technology by society as a whole, especially by major donors and foundations is not high, which leads to the fact that the promoters are mainly technology companies, while foundations do not take the initiative to introduce and link the data. this directly determines that the degree to which blockchain is actually applied to philanthropy is not high.

In fact, Ant Financial Services Group added blockchain technology to a public charity project in 2017, but in the end, the project manager did not use blockchain technology for information entry.

Second, the governance of blockchain on public affairs is not a corporate model, and it often requires multi-faceted coordination and cross-border participation in order to operate, such as the aforementioned "Nansha city brain" block chain function. it is necessary to thoroughly get through the data of the regional political and numerical bureau, political and legal commissar, and health department, and the platform also needs to verify this.

For areas like Hubei, which are already worried about the epidemic, it is obvious that the technology, consciousness and energy are not enough to establish such an overall management mechanism that participates in the management together in the whole time.

Third, blockchain is a comprehensive solution of cryptography, database and other technologies, and its technical application is also in the exploratory stage, so the training of talents in the industry also needs time to mature, and the industry lacks a unified standard. Talent quality and knowledge structure are also difficult to verify, which leads to social institutions in the introduction of this technology is difficult to efficiently and perfectly construct the talent matrix, naturally promote no way.

At this point, it must not be difficult to understand that using new technology as a weapon of epidemic prevention tests not only the maturity of the technology itself, but also the humanistic accumulation of technology by the whole society. Only fertile soil can make the best use of technology.

That is why today we have many new tools for the governance of public affairs, but their progress is full of twists and turns.

As Brecht said, the purpose of science is not to open the door to infinite wisdom, but to draw a line in front of infinite fallacies. I hope that one day these fallacies will not make mankind pay the price of blood.
