3. Blockchain + government
in statistics, voting, budget management and other aspects, blockchain can rece costs, improve efficiency, and increase transparency, so as to prevent the risk of failure of centralized system
4. Blockchain + insurance
fraud identification and risk prevention: by placing insurance claims under an unchangeable general ledger, blockchain helps to eliminate the common sources of fraud in the insurance instry
property insurance and accidental injury insurance: policies and shared ledgers recorded in the form of smart contracts can improve the efficiency of property insurance and accidental injury insurance
Health Insurance: blockchain technology enables medical records to be encrypted and shared among health service providers, thus improving the interoperability of the health insurance ecosystem
Reinsurance: the information security of reinsurance contracts on the blockchain platform can be ensured through the form of smart contracts, which can rece the amount of information and simplify the payment process between insurers and reinsurers
A: application fields of blockchain technology
I. financial field
blockchain has great potential application value in international exchange, letter of credit, equity registration, stock exchange and other financial fields
Second, the Internet of things and logisticsblockchain can also be naturally combined in the field of Internet of things and logistics
through the blockchain, we can rece the logistics cost, trace the proction and transportation process of goods, and improve the efficiency of supply chain management
Third, in the field of public service, blockchain is closely related to people's proction and life in the fields of public management, energy and transportation. However, the centralization of these fields also brings some problems, which can be transformed by blockchain Fourthly, in the field of digital right, through blockchain technology, works can be authenticated to prove the existence of text, video, audio and other works and ensure the authenticity and uniqueness of ownership In the field of insurance, insurance institutions are responsible for fund collection, investment and claim settlement, and often have higher management and operation costs Sixth, the data stored on the public welfare fieldblockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios

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.
1. Blockchain plus supply chain finance nowadays, the supply chain of most commodities, from providing raw materials to manufacturing finished procts, will involve several upstream and downstream small and medium-sized enterprises; And these enterprises are facing the pressure of unlocking supply chain working capital. Supply chain finance means that banks and other financial institutions make systematic financing arrangements for all member enterprises of the supply chain, so as to form a win-win situation between the core buyer enterprise and the supplier: the buyer optimizes the working capital, and the supplier generates additional operating cash flow, so as to minimize the risk of the whole supply chain. The traditional supply chain finance has three pain points: 1. Information can not be shared, low efficiency, poor credibility; 2. The circulation of bills is inconvenient, the settlement of contracts is slow, and there are often capital risks; 3. Credit cannot be transferred and financing is difficult. Blockchain can achieve the following functions: 1. Core enterprises, multi-level suppliers and financial institutions share transaction data, a / R and a / P data and protect business privacy; 2. The circulation of enterprise creditor's rights, automatic settlement of funds, and acceleration of enterprise payment and repayment; 3. The payment commitment of core enterprises is transferred between multi-level suppliers and financial institutions to transfer the credit of core enterprises
2. Blockchain traceability in the field of commodity traceability, the combination of blockchain and Internet of things technology can trace the whole process of commodity circulation, so as to avoid illegal vendors making use of the information asymmetry in the commodity chain to proce fake and shoddy goods. To prevent some participants from tampering with data or falsely claiming the loss of information when it is not concive to their own situation, resulting in the difficulty of proof and accountability. In addition, blockchain traceability can break through the information islands in different links of the supply chain and improve the cooperation efficiency of the supply chain
3. Blockchain helps the blockchain technology of medical services to open up many links, such as hospital prescription, pharmacist prescription review, drug distribution, drug payment, process supervision, etc. Through the distributed storage of blockchain and the accurate matching of information on the chain with patients, we can ensure the one-time dispensing effectiveness of prescriptions, eliminate prescription modification or abuse, and facilitate supervision. In the future, patient information, prescription information and drug circulation information can be encrypted and desensitized through blockchain technology, which can open up more medical application scenarios
4. The integration of blockchain and IOT instrial Internet at the 5th World Internet Conference, the supet instrial Internet platform, which integrates the Internet of things and blockchain technology, was selected as the world's leading Internet technology achievements and became the only award-winning instrial Internet platform
in addition, blockchain data sharing, blockchain judicial chain, blockchain charity, trusted digital content right services, etc. In such instries as government, finance, instry and logistics, health care, retail and Internet, block has a wide range of business application scenarios.
Recently, blockchain is the most eye-catching one that appears frequently in major media
three , blockchain data is completely open and transparent. If anti anonymous identification technology can be developed in the future and a user's information can be seen through password cracking, the positioning and identification of some key targets may also pose a threat to data security and personal privacy
At present, supervision is still on the way. Decentralization means that the main body is not clear, which also brings great difficulty to supervision; In particular, regulators under the blockchain technology will face the "huge amount" of data, and it is difficult to achieve accurate supervision by standardizing the transparency of information. In addition, the vacancy and lag of regulatory legal system make the use of blockchain lack of necessary institutional norms and legal protection, and increase the market riskobviously, blockchain technology is not a "safe box" to ensure the absolute security of financial instry and other economic activities, nor a "panacea" to serve all economic activities . Both the enterprises involved in the research and development and application of blockchain technology and the investors involved in the investment of instrial projects in blockchain should maintain a cautious and rational attitude
1、 Blockchain technology concept
blockchain technology is a new technology with the graal rise of encrypted digital currency. It adopts a distributed computing mode, uses blockchain to store data, uses cryptographic principle to ensure the security of transmission and access, and the data storage is jointly maintained and supervised by Internet users, with decentralized, transparent and open functions Data can not be modified and other significant features [2]. Its use of distributed storage and computing power makes the rights and obligations of the entire network nodes the same. The nature of data in the system is the common maintenance of the whole network nodes, so that the blockchain no longer relies on the central processing node to achieve distributed storage, recording and updating of data. Therefore, its application is not limited to currency as an asset type, At present, it is widely used in various instries{ RRRRR}
