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.

5. The biggest feature of jinwowo network technology analysis blockchain is decentralization
at present, the traditional database is centralized recording and storage. Even for remote disaster recovery and cloud storage, it only changes the storage location from one place to multiple places, from local to cloud. If there is a problem with the central server, the disaster recovery database will stop updating data; The blockchain database is distributed record, distributed storage and distributed propagation. Each information is transmitted by a single node to all other nodes in the whole network. Each node is responsible for data recording and storage. No centralized or third-party organization is responsible for management. If one node has problems, other nodes will continue to update and store data, Through the way of decentralization, the stable operation of the system is maintained, and the information is complete and reliable.

6. Both became families
7. Sum software is not only the network platform for the application of blockchain technology, but also the real application of blockchain in China.
8. Explain blockchain with scientific language --- blockchain is a permanent and irreversible modified record generated by superimposing encrypted data (blocks) in chronological order. Many financial institutions in the world, including JPMorgan Chase, HSBC, Citibank and New York Mellon bank, have also cooperated with blockchain companies to study the application of blockchain technology in the financial market. The person in charge of the blockchain Technology Laboratory of Shanghai Heshu software said that when there is no trusted third party in blockchain, all transaction data will be stored in a data block, and the transaction information will form a complete chain and be included in the blockchain, which is a more reliable ultimate solution than the trusted third party.
9. The five characteristics of jinwowo network analysis blockchain application technology are as follows:
1 - decentralization
2 - distrust
3 - open and transparent
4 - collective participation
5 - distributed ledger.
