A. Can blockchain change 10 cases of existing business?

This article introduces the current 10 main usage scenarios of blockchain:

(1) Tracking products in the global supply chain;

is a typical usage scenario of blockchain technology in security traceability. It can promote information tracking, query, verification and anti-counterfeiting of commodity circulation, and can significantly improve the efficiency of some links. However, the role of the blockchain can only be reflected in the chain, but it cannot cover the parts operated by people below the chain.

(2) Guarantee 3D printing quality and tracking;

(3) Create personalized and lifelong “one-stop” medical records;

Blockchain healthcare can track anyone’s complete medical history, such as medications , illnesses, injuries, and transactions across health systems, physicians, pharmacies, and health plans, and empowering patients to control their own data. Blockchain can also transfer insurance payments: smart contracts can automatically trigger insurance provisions when a clinic confirms a patient has received treatment and prevent fraudulent or inaccurate claims. Some startups, such as the UK's Medicalchain, blockchain company Gem, MIT and other companies and universities are experimenting with this use.

(4) Simplify trade logistics;

Traditional trade involves complex import and export procedures, and all participants in the entire chain require a large number of paper documents to interact, resulting in high communication costs. Blockchain can optimize this system. Maersk and IBM have created a platform that integrates services such as liner, warehouse, freight forwarding, ports, customs, exporters, importers and trade finance banks into the trade ecosystem, on a data exchange platform running on the blockchain interoperate.

(5) Facilitate and secure customs trade;

Blockchain has been tested in many customs departments, including the United Kingdom, South Korea, Singapore, Costa Rica, Mexico, Peru and the 15-nation East African Group. In 2017, U.S. Customs developed 14 use cases for blockchain, which are currently being tested and evaluated. Blockchain will be particularly useful for the UK: when the UK leaves the EU customs union, its number of customs declarations will increase from 55 million to over 250 million (non-EU trade plus EU trade, which previously did not require customs documents), which is currently the case with UK software The program cannot fully handle it. Blockchain can help: It can trace the origins of products and help determine the origin and appropriate tariffs for goods, such as those destined to join the European Union’s tariff package. For the UK’s 28 border agencies, imported products such as food, safety and intellectual property compliance need to be analyzed, and blockchain projects can be shared securely and transparently in real time.

(6) Prevent voting fraud and protect voter identities;

Blockchain security and identity protection features can reduce fraud and encourage voters to believe their votes are anonymous,

increase turnout and make elections more immediate . Using the technology, voters can scan their thumbs with their smartphones and cast their ballots during their Election Day commute. If everyone votes via the blockchain, no one can vote twice. Voting records are inviolable, every voteThe ID of each ballot will be recorded instantly.

(7) Launch crop insurance for farmers;

Crop insurance customized to specific farmer needs is often very expensive, and blockchain technology can reduce costs by determining trigger conditions and automating execution. For example, farmers can insure against extreme weather. If extreme weather affects a harvest, a blockchain-based insurance contract would immediately recognize this and pay the farmer’s claim.

Establishing a network of energy producers and users;

Decades ago, some companies introduced smart grids to provide intermediary services for energy producers and demanders. Now, blockchain can optimize smart grids and provide energy producers and consumers with a regional intermediary energy trading platform. TenneT and Brooklyn-based startup LO3 Energy are both trying this business.

(9) Create smart cities that can operate independently;

Blockchain can now amplify the impact of Douyou IoT on city operations. For example, Dubai has a pilot project to implement blockchain in city services. Dubai plans to use blockchain for more than 100 million annual government documents by 2020, including all visa applications, bill payments and license renewals.

(10) Automatic payment to the exporter when the goods arrive at the foreign buyer;

Blockchain changes the information asymmetry in existing international trade by allowing both parties to the transaction to access the same data and real-time digital files question. There is no need to store multiple copies of the same document across different databases for different entities. When goods arrive marked by sensors connected to the smart contract, a transfer of money from the buyer to the seller is automatically triggered.

2. Ten major problems currently faced by the blockchain industry and their analysis

2.1. Is the data on the blockchain really immutable?

Can one of the core features of blockchain, "anti-tampering", really be realized? And is "tamper-proof" really beneficial?

The report pointed out that the blockchain is not completely immutable, and gave three weaknesses of the blockchain:

(2) It may be hacked, and 51% of the chain is controlled by people who want to tamper with the results.

(3) The "garbage of garbage" problem has existed for centuries. The value of a blockchain depends on the data on the chain, and data entered into the blockchain may be inaccurate or fraudulent. One solution is to use sensors instead of manually entering data.

The so-called "51% attack" is to take advantage of computing power to cancel payment transactions that have already occurred. If someone masters more than 50% of the computing power, he can find the random numbers needed to mine the block faster than others, so he actually has the absolute and effective right to decide which block. From a technical level, a 51% attack is achievable, but the cost is very high for the earliest cryptocurrencies such as BTC. They have built a huge network, which is why BTC’s network has remained stable for 10 years. reason. But with other counterfeit currencies, the risk is greater.

In addition, there is no direct benefit for the attacker to simply launch a 51% attack, and it must be linked to specific short selling and false recharge. Specifically, it oftenOften it is a double expenditure for a certain transaction. The attacker stops attacking once. Continuous attacks are costly and will stop once successful; second, the community can issue an emergency pudding and add checkpoints to the blockchain. The community urgently agreed that the attacker’s blockchain was invalid. Therefore, there are many ways to deal with the 51% attack, and it will not be the end of the world for a blockchain.

2.2. Who owns and maintains the blockchain? And who asked about the appearance?

Responsible for problems and losses?

Since the blockchain is a decentralized user community, who will maintain it? Shouldn’t it require human adjustment and maintenance just like a website?

For permissioned chains, such as alliance chains and private chains, there is no need for incentives such as tokens to motivate people to manage, there is a manager who manages the entire network. Since there are fewer users in the network, coordination costs are relatively low. However, such networks are susceptible to security challenges, and as the number of network users increases, coordination costs will increase.

For consortium chains and private chains, since they are still very centralized organizations, the verification nodes are identified by the organization itself, so the management model is not very different from traditional centralized institutions. However, for public chains, there is no leader who coordinates the entire network system, and only relies on token incentives to coordinate different interest groups, which undoubtedly increases the instability of the entire ecosystem. At present, the development of the blockchain industry is in a very early stage. In addition to the relatively mature decentralized governance of BTC, in the governance of public chains such as ETH and EOS, the founder development team plays a very core role and is the "rules" of the public chain. "Maker", although the entire ecosystem has achieved partial decentralization, the founders still play a pivotal role in the direction of strategic development. Therefore, the author believes that the decentralization of blockchain can only be an ultimate goal that is constantly approaching. From the birth of the project to its maturity, its degree of decentralization should continue to increase, as shown in the figure below. In the early stages of project development, the founder and his development team play an absolute guiding role in the entire ecosystem. As the project ecosystem matures and the number of participants continues to increase, the original development team should gradually weaken its guiding role. The entire network maintenance needs to be decided jointly by all developers and users in the ecosystem. As for the final network problems, they can only be borne by all participants.

Figure: Schematic diagram of the relationship between the degree of centralization and development stages of blockchain projects

2.3. Are smart contracts really smart?

The second reason why smart contracts are not yet that smart is that their entries can be manipulated by evil actors, such as contracting parties or miners who add transaction records to the blockchain's ledger of past transactions. One study showed that 3.4% of ETH smart contracts are vulnerable to hackers.

Smart contracts can indeed optimize many intermediate programs, but judging from current industry practice, they are far from being called smart. A qualified smart contract should include all possible scenarios. Because the core essence of smart contracts is "to make the most just ruling even in the darkest environment."

The difference between Ethereum and Bitcoin is that EthereumIt is Turing complete. Through this platform, more types of contracts with more complex terms can be realized. Of course, the cost of this is that the complex contract content makes it more difficult to analyze. Typically, complexity is directly proportional to the probability of a vulnerability; the higher the complexity, the greater the probability of a vulnerability.

As for the concept "code is law" proposed by Ethereum, however, the code has attracted hacker attacks due to its own vulnerabilities, so it is not enough to form the authority of "law". Therefore, it needs the trust and endorsement of the government, lawyers, courts and other intermediary institutions. Compared with coordination, the current contract seems too rough.

2.4. Is there identity theft on the blockchain?

3% of social media accounts are fake, so can fake accounts be created on the blockchain? Can identities on the blockchain be stolen?

Blockchain can create a personal database for users whose data cannot be tampered with, but how to meet the user's "tampering" needs? This may be a paradox in the development of blockchain technology. Regarding user needs, we may need to start from the perspective of on-chain standards and authority management.

2.5. Can blockchains be connected to each other?

One blockchain records the data of an entity or user in one way, while another blockchain records the same data of the same entity or user in another way. In a fragmented system, multiple account books are not connected to each other, which will form a world of "operational islands", or "data islands". Users need to register for multiple systems at the same time to conduct transactions with different people for different purposes.

In view of the value transfer needs of different chains, cross-chain technology is the key, which can effectively connect different alliance chains or private chains, and promote the outward expansion and connection of blockchains. The current mainstream cross-chain technologies include Notary schemes, Sidechains/relays, Hash-locking, Distributed private key control, etc.

2.6. How does the blockchain connect to off-chain databases?

If one party's data and documents are off-chain, and the other party's data and documents are on-chain, can the two parties interact? In the company's database, can half of the company's data on the blockchain interact with the other half of the data?

These challenges are well known and are being addressed. For example, the same queries and analysis can be run in on-chain and off-chain databases. The risk is that data brought from on-chain to off-chain is no longer immutable, and researchers recognize that data security and aggregating, transforming and optimizing on-chain and off-chain data sets are significant challenges.

2.7. Can blockchain facilitate money laundering?

Money laundering is a huge global problem, amounting to 1-2 trillion US dollars, accounting for approximately 2% - 5% of the total global GDP. Banks and authorities are fighting back, spending about $8 billion a year to combat corruption. Banks around the world require KYC verificationcertificate.

Due to the anonymous nature of the blockchain, especially the emergence of anonymous coins, BTC has been criticized by many people as a tool for money laundering. However, the anonymity of BTC is only anonymity on the chain. The interaction between people and the chain, and the interaction between BTC and legal currency will leave traces. It is not as "lawless" as many media have promoted. Each BTC transaction requires the transfer of a corresponding address, and the transaction records of the address can be queried. In addition, the exchange of BTC and legal currency is conducted off-chain and cannot escape supervision. If the actual identity of any party in the transaction is exposed, it will be difficult for all participants in the transaction to escape recourse.

2.8. Will the blockchain consume all the energy in the world?

BTC has an amazing energy demand. Operating Bitcoin for one year requires the energy consumption of Ireland for one year. Because BTC’s POW consensus mechanism requires miners to mine for transaction verification. There are concerns that as the network increases and the value of BTC rises, energy demand will grow rapidly. In fact, miners themselves have incentives to prevent this from happening, and the scalability of the blockchain is limited by availability, energy costs, and the miners' own financial resources. The current alternative is the POS consensus mechanism. The POS mechanism selects validators based on the number of currency holders.

In fact, it can be seen that except for the early batch of cryptocurrencies headed by BTC, the vast majority of current blockchain projects have taken into account the disadvantages of POW and are constantly innovating consensus mechanisms to avoid excessive consumption of energy. Therefore, blockchain is not enough to cause such a huge consumption of energy.

2.9. Will blockchain take our jobs?

Regarding blockchain, if people can trade directly with each other, what impact will blockchain have on intermediaries such as banks and lawyers? Blockchain is unlikely to be a job killer; it will, like any technology, change the nature of work by changing companies’ business and revenue models.

When artificial intelligence becomes popular, people will continue to ask questions like this. On the one hand, we enjoy the convenience that technology brings to us, but on the other hand, we are worried that technology will replace us. The biggest challenge of blockchain is not the technology itself, but changing the traditional profit distribution model. Blockchain technology can remove certain intermediary links, break the monopoly of many resources by centralized institutions, and thus change the interest pattern. This is also the most revolutionary point of blockchain.

2.10. Is the United States lagging behind in the development of the blockchain industry?

Globally, the blockchain industry in the United States is still in its infancy. Deloitte surveyed 1,053 executives in financial services, healthcare, technology industries, telecommunications, manufacturing and other industries in 2018. According to the survey, only 14% of American respondents believe that blockchain is used in their production, compared with 49% in China, 48% in Mexico, 40% in the United Kingdom, and 36% in Canada. Plans are also lagging: 41% of U.S. companies plan to invest $1 million or more in blockchain, compared with 85% in China, 74% in Canada, 72% in the United Kingdom, and 65% in Mexico.

According to Silicon Valley InsightsJudging from the "White Paper on the Development of Blockchain in China and the United States" released, in terms of the number of ICOs, North America is comparable to Asia. In terms of the amount of financing, North America is far ahead with 7.85 billion. Therefore, the United States, as a major country in North America, is not lagging behind at all. On the contrary, it is still leading in many aspects.

Related questions and answers: What are the uses of blockchain technology in the business field?

What are the uses of blockchain technology in the business field?

In recent years, due to the virtual digital With currency speculation booming, blockchain, as its underlying technology, has also begun to receive widespread attention. Blockchain has the characteristics of decentralization, trustlessness, collective maintenance, and reliable storage. It is currently widely used in the field of virtual currency.

Since the birth of Bitcoin, more than 1,600 virtual currencies have appeared in the world, and a huge industrial chain ecosystem has been formed around the generation, storage, and trading of virtual currencies. But overall, the industry is still in its infancy and is still far away from the real value use area. The core of the blockchain economy lies in the reconstruction of business logic and organizational forms, so it is necessary to obtain practical examples in multiple industries to demonstrate its value. This article will explore the business models used by blockchain in various industries from the perspective of combining blockchain with industry needs.

First of all, the core of blockchain is to solve the problem of credit:

Credit is the foundation of all commercial activities and finance. The United States has implemented trusted identification since 2011, while China has implemented a real-name system to achieve supervised information dissemination. The significance of blockchain is that it has established decentralized trust from a technical level for the first time and realized a completely distributed credit system.

Secondly, blockchain solves the problem of value exchange:

Traditional networks can achieve point-to-point transmission of information, but cannot achieve point-to-point transmission of value. Because information is allowed to be copied, and value must be authentic and unique, it is necessary to rely on a centralized organization to achieve value transfer. Blockchain perfectly solves this problem and provides a method to realize point-to-point transfer of value. During the value transfer process, accounting is realized by the network without relying on a centralized institution. Therefore, blockchain is expected to become a new financialinfrastructure has become the cornerstone of the future value Internet.

The use of blockchain

There are currently two main modes of blockchain use:

1) Native blockchain use: directly based on decentralized blockchain technology to realize value Transmission and transaction use, such as digital currency;

2) "Blockchain +" model: combine traditional scenarios with the underlying protocol of the blockchain to improve efficiency and reduce costs. It is expected that the use of blockchain in various industries will be dominated by the second model.

Blockchain has five core attributes, namely: transaction attributes (value attributes), certificate attributes, trust attributes, intelligence attributes, and traceability attributes. The above core attributes are combined with the needs of the industry to solve the industry's pain points and become the business model used by blockchain in various industries.

Blockchain + Bank

1. Cross-border payment

Cross-border payment is a pain point that has long plagued the banking industry. Traditional cross-border payment methods include two major categories: one is online payment, including electronic account payment and international credit card payment, which is suitable for small retail amounts; the other is the bank remittance model, which is suitable for large-amount transactions; both have payment cycles Long, high fees, low transaction transparency and other issues. Especially in recent years, with the rise of cross-border e-commerce, convenient, fast, safe and low-cost cross-border payment has become an urgent need for the industry.

The role of blockchain:

The characteristics of blockchain are deintermediation and open and transparent transactions. There is no third-party payment institution to join, which shortens the payment cycle, reduces fees, and increases transaction transparency. For example, in December 2017, China Merchants Bank teamed up with Wing Lung Bank and Wing Lung Shenzhen Branch to successfully implement cross-border RMB remittances between the three parties using blockchain technology. Its clearing process is safe, efficient and fast, greatly improving customer experience.

2. Supply chain finance

The pain points in this field are the long financing cycle and high costs. Centered on the core enterprise system of the supply chain, it is difficult for third-party credit enhancement institutions to authenticate the authenticity of various relevant vouchers in the supply chain, resulting in long manual review times and high financing costs.

The role of blockchain:

Blockchain introduces consensus mechanism, existence proof, non-tampering, traceability and other features into supply chain finance, and does not require third-party credit enhancement agencies to authenticate various relevant credentials in the supply chain. authenticity, thereby reducing financing costs and shortening the financing cycle. For example, in April 2017, the listed company Yijian and IBM China Research jointly launched the blockchain supply chain financial service system "Yijian Block". The system focuses on pharmaceutical scenarios and currently has more than 30 pharmaceutical distribution companies. Successfully registered in the "Yijian Block", as of the end of July, the number of transactions had been close to 8,000, and the total investment amount exceeded 100 million yuan.

3. Digital Bills

The pain point of the digital bill industry lies in the long-term problems of “false bills” and “selling more than one ticket”, which have brought risks to the bill financing business of the banking industry.

The role of blockchain:

The existence proof and non-tampering characteristics of blockchain effectively solve the problem of false digital bills; at the same time, blockchain solves the double-spending problem and can avoid" sell more with one ticket. For example, Shenzhen Blockchain Financial Services Co., Ltd. issues ticket chain products to provide ticket financing services based on blockchain to solve the ticket financing needs of small, medium and micro enterprises. Cooperative banks include Ganzhou Bank and Guiyang Bank , Suzhou Bank, Shizuishan Bank, Langfang Bank, Wuhai Bank, Jilin Jiutai Rural Commercial Bank, Yaodu Rural Commercial Bank, Shenzhen Rural Industrial Bank, Weifang Bank, Zhongyuan Bank, etc. In addition, Zheshang Bank, Jingdong Finance, Hang Seng Electronics , HNA, etc. are also verifying blockchain digital bill services.

Blockchain + Securities

1. Asset Securitization

Asset securitization uses future income as a guarantee to obtain current financing. The The pain points in the field are: there are many participating entities, many operating links, low transaction transparency, information asymmetry, and the authenticity of the underlying assets cannot be guaranteed.

The role of blockchain:

Blockchain introduces existence to asset securitization With attributes such as proof of authenticity, non-tamperability, and consensus mechanism, it can monitor the true status of assets in real time and solve the problem of trust in underlying assets by all parties in the transaction chain. Various assets such as equity, bonds, bills, income certificates, warehouse receipts, etc. It can be integrated into the blockchain and become a digital asset on the chain, improving the efficiency of asset circulation and reducing costs. For example, in May 2017, Internet Finance and partners including Baiqian Leasing, Huaneng Trust, etc. jointly issued a blockchain The asset securitization ABS project supported by technology has an issuance scale of 424 million yuan.

Blockchain + Insurance

1. Insurance business

There is information asymmetry in the insurance industry and a lack of trust between customers and insurance institutions Problems such as: It is difficult for users to choose insurance products that suit them, and insurance institutions face the risk of insurance fraud.

The role of blockchain:

The decentralization, openness, transparency, and traceability of blockchain, Establish a good communication channel between insurance institutions and users; insurance subject information is managed uniformly on the blockchain and cannot be tampered with, helping insurance institutions avoid the risk of fraudulent insurance; at the same time, smart contracts can improve work efficiency and reduce costs. For example, France Insurance giant AXA is using the Ethereum public blockchain to provide automatic flight delay compensation for air passengers. If the flight is delayed for more than 2 hours, the "smart contract" insurance product will automatically pay the claim to the passenger.

2 , Credit information management

The pain point in this field is that credit information agencies have limited data collection channels and a lack of data sharing, making it difficult to accurately characterize the credit status of individuals or institutions; in addition, there are also issues about how to protect user privacy during the data collection process. .

The role of blockchain:

Blockchain has the characteristics of trustlessness, consensus, and non-tampering. At the technical level, it ensures that limited and controllable credit data can be achieved on the basis of effectively protecting user privacy. Sharing and verification. For example, Ping An’s blockchain credit reporting business is now online. In addition, domestic startups such as Shanghai Juzhen, LinkEye, Bubi Blockchain, etc. are also conducting joint credit reporting and safe certificate deposits. Exploration.

As a basic technology, blockchain hasIt has great use value in industries that require distributed processing, point-to-point transactions, and rapid establishment of trust relationships. Its core is to solve the problem of credit and realize point-to-point transfer of value. Therefore, it is considered to be the cornerstone of the future value Internet.

The core of the blockchain business model is to use the innovative attributes introduced by the blockchain and combine it with traditional industry uses to realize the reconstruction of business logic in order to create new usage scenarios, or improve efficiency and reduce costs.

It is expected that the use of blockchain will first start in the pan-financial field that has high requirements for credit, efficiency, and security: the financial industry pays more attention to efficiency and security, and blockchain has a high degree of matching with its pain points, and can be used for Systematically solve trust issues, efficiency issues, default risks, etc. that exist in all aspects of financial services; blockchain’s attributes such as “transaction, certificate storage, and traceability” are more likely to generate value in the financial industry. At the same time, the market space in the financial industry is huge, and small progress can bring huge benefits.

Blockchain will also extend to all areas of social life: Blockchain solves problems such as the management, transaction, and transfer of digital assets, and therefore will play an important role in the wave of asset digitization, such as supply chain management, data Applications such as services, asset management, public services, and the Internet of Things are gradually being implemented in various fields, and "blockchain+" is becoming a reality.

B. When the medical and health field encounters blockchain + artificial intelligence

Big data, blockchain, artificial intelligence, Internet of Things, etc. are all hot topics in recent years. It has also become a hot spot in the market from time to time. With the rapid development of science and technology, the two most important pieces of so-called financial technology are blockchain and artificial intelligence.

The characteristic of blockchain is that it combines distributed storage technology with consensus mechanisms and encryption algorithms, and realizes point-to-point transmission, through which different nodes in the network jointly participate in the recording and storage of data. Distributed storage is gradually decentralized and flattened, making data storage faster, safer and cheaper, which is what various fields are currently pursuing.

While technology continues to mature and improve, the application fields of distributed storage and artificial intelligence are also constantly expanding. Distributed storage can realize massive and efficient data storage, while artificial intelligence can deal with massive data. Analysis of data.

Distributed storage encrypts and stores data on different nodes through data segmentation, which improves the security of data storage and reduces the cost of data storage. At present, a large number of enterprises store data in centralized databases. Once the server is attacked or malfunctions, it will cause problems such as large-scale network paralysis or data loss, especially for some institutions where large amounts of data are concentrated, such as medical institutions, express delivery companies, etc. , more vulnerable to hacker attacks.

Take the analysis of medical institutions. Such institutions always have various troubles when it comes to data quality, including not only attacks by hackers, but also errors by clinicians, ranging from medical records to medications. Storage of treatment certificates into electronic medical records is not availableEffective and safe solution. Blockchain can use distributed technology and redundant technology to divide these data into fragments and store them encrypted on different nodes. The data processing speed is greatly improved compared to the previous centralized centralized management. Due to the use of encryption technology, it is further guaranteed Regarding patient privacy, even if a hacker breaks into a certain node, the security of the data will not be affected.

The use of artificial intelligence deep learning to assist patient diagnosis and management, and through the analysis of case medical images, will help doctors make more accurate and efficient treatments. Combining distributed storage with artificial intelligence, artificial intelligence can provide timely health reminders to stored data and maintain correct editing and updating of electronic medical records.

Although the application of artificial intelligence in the medical field has always been controversial, with the in-depth development of machines and technology, and the much less controllability of artificial intelligence in the medical field, in the future, with the help of artificial intelligence applications Diagnosis and health management will also become a trend.

The application of distributed storage in the medical field also has broad prospects. It can not only improve the utilization of storage resources, but also provide a basic guarantee for the security of data storage. Combining distributed storage with artificial intelligence is of great significance to improving medical efficiency.

C. What is the most important change in the blockchain business model

Blockchain-based intellectual property protection It is possible to establish truly unique intellectual property rights in the blockchain. The first is authentication and the second is protection. Some media groups want to ensure the authenticity of data based on blockchain and real accounting in the future.
2.
If a platform like this is established for micro-knowledge content, micro-notarization, micro-publishing, and public innovation, a large number of Weibo and WeChat, including what I said today, will be original. , will be registered on the blockchain at a very low cost. After registering, you can micro-publish. It will be profitable in the future. Even if everyone uses it, I'll get a penny. That's a lot of profit. How big is the market? This is definitely not about using traditional publishing houses to take away their publishing market of more than 1 billion pounds. That's worth tens of billions of dollars.
3.
Wearable instruments and blockchain medical records At present, due to the lack of smooth communication of information, there is a great conflict between doctors and patients. Originally, everyone’s medical records

D. What changes will the combination of blockchain technology and the medical industry bring?

The emergence of blockchain technology has made the original personnel database and health Transaction information becomes outdated. Blockchain technology can improve the overall security of data and greatly save explicit and implicit costs. If this new recording method becomes a reality, tragedies such as the inferior children's vaccine that occurred in 2016 will not happen. At present, it seems that the application of blockchain technology in the medical field can be well reflected in the following aspects: electronic health records, DNA wallets, drug anti-counterfeiting and protein folding. Electronic health records, DNA wallets, drug anti-counterfeiting and eggWhite matter folding.

Protein folding

Simulating the folding process of proteins is quite time-consuming and laborious. Previously, the world-famous Stanford University relied on very expensive supercomputers to simulate proteins. The whole process of folding, but the disadvantages of this method are also obvious: it costs a lot and there is a single point of failure.

Using blockchain technology, a distributed network can be established to assist protein folding. Each node in the node network can use the computing power of the entire network when performing calculations. When 10,000 computers in the entire network can reasonably calculate a data, researchers no longer need to purchase expensive super hosts.

E. Is the blockchain electronic medical record recognized by the Health Commission?

Recognized. The National Health and Medical Commission is working hard to explore the application scenarios of blockchain in the medical and health field, using the characteristics of blockchain that cannot be tampered with, is safe and trustworthy, and actively promotes the introduction of blockchain technology into electronic health records to transform health into Liquid transportation records such as file browser access, health file API access, and mutual recognition of inspections and inspections are "chained" and "encrypted", so the National Health Commission recognizes blockchain electronic medical records.
