Lingting: Under the disaster, the blockchain needs a "medical observation"

The number of patients is updated every day, affecting the hearts of hundreds of millions of people; doctors are dispatched, troops are taken over, rescue supplies are shipped from all over the world; shopping malls are closed, stations are stopped, and citizens are trapped in their homes. Most Chinese cities have been pressed for the pause button. . A sudden-onset virus caught us off guard. As of press time, the number of confirmed new-type coronavirus pneumonia nationwide has exceeded 50,000.

At this moment, the motherland is suffering and compatriots are suffering. No Spring Festival is so difficult.

Some people say that under this "war epidemic", the collective absence of the blockchain and the collective loss of the collective voice of the blockchain people could have achieved a more transparent and efficient bottom layer of technology. In contrast, big data and cloud computing have come in handy. Here, we try to give the blockchain and also do a "medical observation." From a longer historical period, what should we summarize and reflect on from this epidemic? In the past week, Lingting Blockchain (WeChat ID: xialingmeili) communicated with many experts in the industry. The following core points are shared with you.

Challenges or opportunities in a disaster?

In response to this problem, Meng Yan, deputy dean of the Digital Asset Research Institute and a token economic expert believes that when the epidemic broke out, the entire blockchain industry was untied for only 80 days. The blockchain is different from several other technologies. progression stage. However, to a certain extent, the blockchain is indeed late, wasting two years.

It's not just the blockchain that is tested. Zhu Jiaming, Chairman of the Academic and Technical Committee of the Digital Asset Research Institute, believes that behind this "war" against the new coronavirus is not only a comprehensive test and challenge to public health systems such as medical science, medical education, medical structure, and epidemic prevention system. It is also a test and challenge for many years on big data, cloud computing, artificial intelligence hardware and software, and even engineers and programmers.

And Xiao Feng, chairman and general manager of Wanxiang Blockchain, believes that this sudden and large-scale public health incident affecting the world is "organic at risk" for any digital technology and digital industry. Blockchain is also a digital technology, and it is also considered as a digital industry.

"Passing trust" instead of "creating trust"

In this epidemic, the deployment of relief materials such as masks has been questioned a lot. Problems such as untimely deployment, opaque information, and unreasonable distribution methods have repeatedly hit our bottom line of patience.

In the face of such a catastrophe, can we use blockchain to achieve transparency, traceability, and tamper resistance? Will there be a technical solution?

Ma Zhitao, Vice President and Chief Information Officer of Weizhong Bank, said in an interview with Ling: Blockchain can play an active role in public governance, but first of all, we must clarify a misunderstanding: Most people believe that blockchain is a "trusted machine "This is not wrong. But the value of blockchain is not creating trust, but transmitting trust.

People donated disaster relief materials to the Red Cross, in fact, they wanted to pass on this goodwill and trust to the most needed hospitals and doctors. In the middle, if blockchain technology is used, the transfer process can be traced and cannot be tampered with, but the blockchain technology itself does not create trust.

"Centralized systems have the possibility of being tampered with, and the immutable characteristics of distributed accounting can well solve the problem of trust transfer, but the core actually depends on who uses it," he said.

Information on the chain: must be a trusted subject

During the disaster relief process, a lot of rumors and false news appeared, which increased the burden on the disaster relief. Personnel dealing with material donation spend a lot of time and energy to verify the source of supply, and often even struggle with fake news.

Is there a technical solution to make it more efficient and less false?

Ma Zhitao said: The key among them is the main body of the chain. If it is to be solved in an engineering way, it is necessary to ensure that the subject on the chain must be credible, so that the subject is supervised or the relevant qualification is issued to the subject to achieve credibility. These subjects are sometimes organizations, and sometimes individuals. If they are individuals, a trusted agency is required to complete the verification of the information.

"The read permission can be open to everyone, and the write permission must be a trusted subject."

The contradiction between privacy protection and public safety

In this outbreak, the personal information of a large number of patients or suspected patients was spread wantonly, the travel track was exposed, and the contradiction between privacy protection and public safety was magnified.

For example: the illness was originally personal privacy, but some personal privacy information may become a major hidden danger to public safety when encountering a major infectious disease; for example: personal travel during the epidemic, mobile operators have all the information, but whether Provide it out? Should I use my personal privacy information for external use?

In response to this problem, Ma Zhitao told us that there is already a distributed digital identity solution in the blockchain, and Weizhong Bank has open sourced all the source code and made it available to the community for free. However, because the blockchain technology has not yet become the technological infrastructure of the entire society, it has not yet been put into practical use on a large scale.

"Blockchain-based distributed data management and trusted identity authentication solutions can both authorize disclosure with the user's knowledge and allow relevant institutions to reliably track user information. This protects both Privacy can also help public safety. "He said that after the outbreak, they will also speed up the implementation of cases in this regard.

Technology for Good: Eventually Returns to People

During this epidemic, we are moved to tears by the love and kindness of even more tiny individuals. Medical workers struggling at the front line, troops for emergency assistance, a tactical name, and express delivery brothers, community workers, and volunteers who insist on their posts. They paid little by little to maintain the basic operation of society during the epidemic. These people who can't even remember their names have become the most shining spirit.

Although the volunteers do not intend to keep their names, the whole society should encourage and respect goodness. We can't just rely on human conscience and kindness to motivate these positive actions, but we can choose a technical and engineering approach.

"At present, many social rules and laws are proposed from the perspective of punishment. We have proposed the concept of" goodness "from the perspective of positive incentives, and advocated the use of blockchain technology to give quantitative positive incentives to small good deeds. Ma Zhitao said. For example, one volunteer service, one assistance, one low-carbon trip, etc., quantify and chain good deeds, and then redeem corresponding rights and services to accumulate small good to great good. This is a good reflection of science and technology for good.

Li Jieli, general manager of Ant Blockchain, also felt deeply. He told me: The biggest feeling in this outbreak is the separation of the real world from the digital world: "We all think that the digital economy is the future, and we suddenly find people How fragile it is as an organism, and many cutting-edge digital technologies, including blockchain, are actually very weak in the face of the epidemic. So we are also reflecting, whether it is the digital economy or the development of various productivity. After all, it is to serve people. "

It is expected that all practitioners can use technology to help people live a better life, build a social infrastructure with a "pre-emptive" mentality, and use a longer-term and more durable mentality to solve some basic problems. There shouldn't be so many "too late" in life and society. No one can be a spectator before the catastrophe.
