Combination of blockchain and hospital

1. 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.

2. There are many advantages of blockchain technology in the medical field.
① a very important component of "network routing" blockchain system structure is a peer-to-peer network without centralized server. The specific advantage of blockchain technology in the medical field is that hospitals no longer need to establish a centralized patient information management service platform, Centralization of the flat, then very bad thing, once the network "stuck, delay" the whole hospital patient management system will run slowly, but also affect the efficiency of the whole treatment
② the use of blockchain technology can better deal with the speed of seeing a doctor and solve the financial problems of many patients, and "easy financing" is a good example.

3. 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.

4. Blockchain uses "algorithm proof mechanism" to ensure this trust
jinwowo Group believes that with this trust, all nodes in the whole system can exchange data automatically and safely in a trusted environment
compared with other time-consuming and expensive tool technologies, it can automatically match and enforce in real time at a low cost. 11 "intelligent trust" brought by blockchain Technology

5. There's a mining machine in the cave. You can get ore for 10 gold coins, but sometimes you can't

6. Of course, if it is applied to any specific scenario, my personal understanding of blockchain technology is not very clear. So for my understanding, I'd like to talk about several areas that can be applied. Based on the characteristics of blockchain Technology:
1) patient information can reflect the patient's information more truly
2) it can better show the hospital's qualification, and make clear the diagnosis and treatment process and results of past patients in the hospital
3) it can better sort out medical resources, such as blood group matching, kidney, and even other organ resources
4) make the doctor's qualification certification, the source of medical equipment, and some relevant information more accurate
5) drug anti-counterfeiting can verify the authenticity of drugs (although the blockchain technology can not directly prove the authenticity of real objects, there may be ways to overcome it in the future.)
the above are my personal views, just my personal views. In the future, blockchain technology has great potential in both virtual level and practical application scenarios, but it will not replace traditional technology, but will only combine with each other to learn from each other.

1. Medical

in the medical field, data sharing between hospitals and micro v-bq-y means more accurate diagnosis, more effective treatment, and can promote the overall service ability of the medical system. However, data sharing also means the problem of doctor-patient privacy exposure. Blockchain technology allows hospitals, patients and all parties in the medical interest chain to share data in the blockchain network without worrying about the security and integrity of the data

2. Logistics

at present, the most critical problems of logistics are missing and damaged express. Blockchain technology can record all links in the process from delivery to acceptance of goods, and directly locate the problems in the intermediate links of express delivery through network consensus, so as to ensure the traceability of information, so as to avoid the occurrence of problems such as warehouse explosion, package loss, wrong picking and wrong picking

3, big data

big data is an indispensable link in the development of modern enterprises, and the security and non tamperability of blockchain can liberate more data security. Based on the consensus of the whole network, the data reliable blockchain data, which is the basis of micro v-bq, is tamperable and safe, and makes the quality of data obtain unprecedented strong trust endorsement, and also makes the development of database enter a new era

4. Distributed business platform

combined with the advantages of decentralized blockchain technology and distributed account book, there are many integration points worthy of attention in the field of this technology and business platform. If we can take blockchain technology as the core support technology, research and develop the transaction mode and transaction system based on blockchain technology in the field of commodity trading, and trade directly, in this way, Procers can get more benefits and consumers can get lower proct costs

Generally speaking, blockchain system consists of data layer, network layer, consensus layer, incentive layer, contract layer and application layer

among them, the data layer encapsulates the underlying data blocks and related basic data and algorithms such as data encryption and timestamp

The

network layer includes distributed networking mechanism, data transmission mechanism and data verification mechanism; The consensus layer mainly encapsulates all kinds of consensus algorithms of network nodes

the incentive layer integrates economic factors into the blockchain technology system, mainly including the issuing mechanism and distribution mechanism of economic incentives

the contract layer mainly encapsulates all kinds of scripts, algorithms and smart contracts, which is the basis of the programmable characteristics of blockchain

The

application layer encapsulates various application scenarios and cases of blockchain

in this model, chain block structure based on timestamp, consensus mechanism of distributed nodes, economic incentive based on consensus computing power and flexible and programmable smart contract are the most representative innovations of blockchain technology

8. Since last year, ant chain and Zhejiang Province have built the country's first blockchain e-bill platform, which allows people to make an online appointment directly without having to queue up repeatedly to pay at the required window. To be more accurate, it is to use unified digital encryption technology on the electronic bills for charging, so that each bill has a unique two-dimensional code "ID card", which can check the authenticity in a few seconds, fundamentally saving the cost, and more importantly, increasing the accuracy. After all, it is difficult and easy to make mistakes in manual operation, Now with the e-bill platform, both hospitals and indivials are the biggest beneficiaries.

9. After the blockchain medical platform like Rongze is built, the patient information between different hospitals can be connected, which is fidelity, transparent and should not be tampered with, so as to make the diagnosis more reliable and increase the cure probability of patients.
