1. Block chain 3 architecture block chain 3 is mainly used in the field of social governance, including identity authentication, notarization, arbitration, auditing, domain name, logistics, Internet of things medical guards. For example, today's latest news, Ma Huateng pointed out at the 2018 China Internet plus digital economic summit held today, Tencent will use the block chain technology to cooperate with hospitals to prescribe digital prescriptions. In addition, wechat is also launching innovative medical services such as digital medical insurance card in many places.
2.
Because the design of blockchain is a kind of protection measure, such as distributed computing system with high fault tolerance. Blockchain makes hybrid consistency possible. This makes blockchain suitable for recording events, titles, medical records and other activities that need to include data, identity management, transaction process management and provenance management. Blockchain has great potential for financial disintermediation and has great influence on guiding Global trade
extended data :
1. Blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system
2. Blockchain is an important concept of bitcoin, which is essentially a disintermediated database and the underlying technology of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block
3. Blockchain - the original blockchain is a kind of decentralized database, which contains a list called blocks, with continuously growing and orderly records. Each block contains a time stamp and a link with the previous block. The block chain is designed so that the data can not be tampered with. Once recorded, the data in a block will be irreversible

3. The medical and health instry is one of the earliest instries to apply blockchain technology. Blockchain technology has eight application scenarios in the medical instry: 1. Medical and health data; 2. Genome data; 3. Medical insurance; 4. Identification of medical staff; 5. Drug security; 6. Medical supply chain finance; 7. Clinical trials; 8. Surgical records. At present, the most widely used fields are medical health data and medical insurance
at present, Tencent, a domestic Internet giant, has entered the field of blockchain health data. On April 13, Tencent officially released wechat smart hospital 3.0. The new version of wechat smart hospital integrates all medical information into the blockchain, which is supervised on the real-time chain and traceable in the whole process.

4. At present, blockchain is leading the trend of the economic market in various Internet instries, and it is more significant in the medical field. In addition, e to high rendancy, impossibility of tampering, low cost and the ability to manage multi signature complex permissions, blockchain may be the best data storage scheme that human beings can find at present. Medical institutions are using blockchain technology to realize the confidentiality of patients' privacy information
take the PPT big health protection ecological platform on the market as an example:
five applications of blockchain in the medical field:
1. In the aspect of EHR medical treatment, the main application of blockchain is the preservation of personal medical records, which can be understood as the electronic medical records on the blockchain. If you think of the medical record as an account book, originally it is in the hands of various hospitals, and the patients themselves do not master it, so the patients have no way to obtain their own medical records and historical information, which will cause great trouble for the patients to seek medical treatment, because the doctors can not fully understand your medical records. But now, if we can use blockchain technology to save, there will be historical data of personal medical care. Whether we see a doctor or plan for our own health, there will be historical data to use. The real master of this data is the patient himself, not a hospital or a third-party organization
2. DNA wallet gene and medical data can be safely stored by using blockchain technology and obtained by using private key, which will form a DNA wallet. This enables healthcare providers to share and count patient data safely, and helps pharmaceutical companies develop drugs more efficiently. And this model is graally being established
3. The development of bitcoin payment blockchain technology promotes bitcoin payment and gives patients more choices for insurance payment. Although it also depends on the development of bitcoin in the market, the insurance companies that provide this way also have greater advantages than their competitors. For health insurance companies, blockchain is being established as a part of financial services
4. Drug anti-counterfeiting is similar to coding anti-counterfeiting technology. For drugs using blockchain technology, there is a scraped surface on the surface of drug packaging box, and a special verification label under it, which is compared with blockchain technology to ensure the legitimacy of drugs
5. Protein folding e to the rapid process of protein folding, Stanford University previously relied on very expensive supercomputers to simulate the protein folding process. This approach is obviously expensive and has a single point of failure. By using blockchain, they can choose to use a huge distributed network for high-speed computing. This example will greatly attract other companies that use expensive supercomputers. With the development of medical technology, medical data is playing a more and more important role in the aspects of patient identity background, past medical history, and medical payment records. Medical data may be a person's most private data, but e to network operation errors or hacker attacks and other problems, in the past, these personal privacy data were leaked on a large scale. For example, anthem once leaked 80 million patient and employee records, and UCLA health once leaked 4.5 million patient data. The medical convenience brought by blockchain includes: as more and more health and preventive care are provided in a virtual environment, such as at home, at work and so on. Open and viable tracking, validation, and care delivery will become very important for patients, payers, suppliers, scientists, and regulators. The development of these new ohh blockchains in the clinical community will prepare for the study of patients' behavior, and for the important data access of supplier reimbursement, rule compliance, security monitoring and patient compliance in the future. Blockchain is a near perfect technology (not necessarily implemented at present). It can easily and safely access ooh data while protecting the maximum privacy, and rece the interest risk of all patients, including patients themselves, families, caregivers, clinics, suppliers, insurance companies and all stakeholders related to patients' health.

5. First of all, let me tell you about the core technology of blockchain
blockchain mainly solves the trust and security problems of transactions, so it proposes four technological innovations for this problem:
the first one is called distributed ledger, which is that transaction bookkeeping is completed by multiple nodes distributed in different places, and each node records complete accounts, Therefore, they can participate in the supervision of the legitimacy of the transaction, but also can jointly testify for them. Different from the traditional centralized accounting scheme, no single node can record accounts separately, so as to avoid the possibility that a single bookkeeper is controlled or bribed to record false accounts. On the other hand, because there are enough accounting nodes, in theory, unless all nodes are destroyed, the accounts will not be lost, thus ensuring the security of the account data
the second is called symmetric encryption and authorization technology. The transaction information stored on the blockchain is public, but the account identity information is highly encrypted, which can only be accessed under the authorization of the data owner, thus ensuring the data security and personal privacy
the third mechanism is called consensus mechanism, which is how to reach a consensus among all accounting nodes to determine the validity of a record. This is not only a means of identification, but also a means of preventing tampering. Blockchain proposes four different consensus mechanisms, which are suitable for different application scenarios and achieve a balance between efficiency and security. Taking bitcoin as an example, the workload proof is adopted. Only when more than 51% of the accounting nodes in the whole network are controlled can a nonexistent record be forged. When there are enough nodes to join the blockchain, this is basically impossible, thus eliminating the possibility of fraud
the last technical feature is called smart contract, which is based on these trusted and tamperable data and can automatically execute some pre-defined rules and terms. Take insurance as an example. If everyone's information (including medical information and risk occurrence information) is true and reliable, it is easy to carry out automatic claim settlement in some standardized insurance procts
in the daily business of insurance companies, although the transactions are not as frequent as those in the banking and securities instries, the reliance on trusted data is increasing. During the operation of insurance companies, risks caused by various reasons occur from time to time, so the regulatory authorities can only take measures of pre audit or post constraint. However, with the increasing opening of the front end of the insurance business, enterprises participating in the insurance market are becoming more and more diversified, and the demand for in-process supervision is becoming increasingly prominent
as long as the insurance company moves its daily operation process to the blockchain and develops an accounting node (even a read-only accounting node) from the regulatory authority, the regulatory authority can observe all the business trends of the insurance company in real time. Tongxin society is the first domestic application project of blockchain technology and an open mutual aid information service platform. For example, there is no need to wait for the insurance company to declare afterwards, so as to discover the possible business risks and illegal operations in time.

For example, there is no need to wait for the insurance company to declare afterwards, so as to discover the possible business risks and illegal operations in time.
6. To answer this question, let's first introce the advantages and disadvantages of network mutual assistance and the advantages of applying blockchain technology
advantages of online mutual assistance:
online mutual assistance is actually a variant of foreign mutual insurance (or mutual insurance) in China. It inherits the characteristics of some modes of mutual insurance, such as organizational form and management methods. It also makes some changes according to the characteristics of China's insurance market and the current regulatory environment
Internet Mutual Aid relies on the Internet's efficient information matching ability, convenient payment service and low entry threshold, Therefore, network mutual aid has the ability to gather a large number of members in a short time
low cost
at least 50% ~ 80% cheaper than the traditional security scheme
high participation
the value provided by network mutual aid is easily accepted by users
flexible security
flexible procts, It can launch mutual aid procts for all kinds of people
shortcomings of online mutual aid:
operation is not transparent
there may be problems such as platform fabricating mutual aid events to obtain users' funds
user privacy
the general carrier of online mutual aid platform is technology company, which lacks supervision and public trust endorsement, Therefore, it is easy to be questioned
inefficient
compensation process is slow
Application of blockchain technology
we think that the emergence of blockchain technology provides solutions to these problems. The network mutual aid application based on blockchain platform can maximize the absolute security of funds, protocols and information, and improve the risk control ability
the flow of funds is transparent
all the details of the flow of funds are recorded on the blockchain, and the data can not be forged or tampered to ensure the authenticity and validity of the data. All regulatory units, public media and ordinary users can view and supervise the implementation of the rules at any time
the rules are efficient
all the funds are transferred according to the open and tamperable smart contract, Once determined, it can be executed accurately, no one can intervene, no legal person can misappropriate or intervene, which improves the efficiency of rule execution
user information security
all personal sensitive information is highly encrypted and stored, unless authorized by the user, Other people can't access and steal
the service will never be down
the network mutual assistance running on the public chain does not depend on whether a central server is online, which can ensure that the service provided will never be down
in the current insurance business, disputes between insurance companies and policy holders occur from time to time, or the policy holders provide false personal information to cheat insurance, Or there are differences in the determination of the exemption clause when settling the claim. The key to these problems lies in the lack of a real and reliable data collection and storage means for the personal information of the insured
with the advancement of national systematic projects such as medical information digitization and personal credit system, more and more authoritative data sources appear. If these data can be introced and stored on the blockchain, it will become the digital identity of everyone. The data above is authentic, can't be tampered with, real-time synchronization and life-long validity, It will bring great benefits to the risk management of the insured
the first is to get through the data between different companies and refer to each other, so as to discover the information of repeated insurance and historical claims in time, and discover high-risk users in time. Taking the 40 million accident insurance fraud in March this year as an example, Zhou of Yangzhou took out insurance in more than ten life insurance companies, which was not found out until the manual underwriting. If every insurance information is recorded in the blockchain, it can be found and timely measures can be taken
secondly, introcing data from different instries into the blockchain can improve the accuracy and efficiency of underwriting and claims verification. For example, if you can query all the medical records of the insured, even the medical records of the immediate family members, on the blockchain, you will have first-hand information about the current physical condition, disease history and family history of the insured, effectively eliminating the insurance with diseases
at present, Tongxin society is the first network mutual aid platform with blockchain technology as the core in China, so blockchain technology is also one of the effective technical means for in-process supervision.

Internet medicine refers to the use of Internet technology to provide health ecation, disease prevention, online prescription and other services, as well as artificial intelligence technology to assist diagnosis of new medical model. Internet medicine has broken the "fence" boundary of traditional hospitals, expanded the service radius, and opened up a new path to broaden the grassroots medical channels
Internet medicine provides doctors and patients with cross regional "screen to screen" treatment mode, which is complementary to the traditional "face-to-face" treatment mode. One is to build a platform for doctors and patients and expand medical channels. Second, it also needs the registration examination and daily management of doctors' qualification. Third, it mainly carries out health consultation, common diseases and chronic diseases return visit, complementing with traditional medical services. The fourth is to provide decision-making reference for traditional medicine by providing artificial intelligence aided diagnosis system and big data analysis
