Shared medical record blockchain

2. Of course, this is OK
first of all, blockchain is actually a centralized database or a decentralized database, and all technical units are for better maintenance of the public database. Each node keeps a of data independently. Consensus algorithm is used to achieve the data consistency of the node's account book, and cryptographic algorithm is used to ensure the data can not be tampered, and the data can not be tampered and the security of data sending and receiving; Through the script system, the expression scope of account data is expanded
secondly, financial sharing center involves a large amount of financial data. We can combine the technical characteristics of blockchain with Financial Sharing Center. Next, I will combine the technical characteristics of blockchain with Financial Sharing Center
① distributed storage is a distributed database of the blockchain, and each node keeps a of the data independently. If this is combined with the Financial Sharing Center, The users who can join the "financial data on the chain" in the financial sharing chain are equivalent to the "nodes" in the blockchain network, and each user can keep a of the financial data separately, so as to achieve the purpose of sharing
② tampering is not allowed. A very important feature of blockchain technology is that the data cannot be tampered, To ensure the security of a data in the Financial Sharing Center, we need to consider the security as long as the financial data is involved.
of course, before doing the Financial Sharing Center, you must determine your specific needs, if necessary, first write a framework of the whole project, and then find a formal blockchain development team according to the needs, To help you develop this "Financial Sharing Center", we must pay attention to that before formal cooperation is reached, don't disclose the information of your project casually, in order to prevent the same kind from being copied.

3. With the emergence of cryptocurrencies such as bitcoin, this time tested financial framework is likely to be changed. With the power of blockchain and the rise of this new data based currency, the whole concept of money has been reversed. Although our current understanding of money has changed over the past few decades, thanks to credit cards and fiat money, cryptocurrency is the logical next step in this evolution
this is understandable for accountants, but what does it mean for entrepreneurs? Well, anyone interested in starting or maintaining a successful business will need a competent accounting team. With the change of financial environment, the experience and insight that business accountants need will also change. Understanding this coming paradigm shift can better help entrepreneurs prove their organization in the future, and may even help them save money on business expenses related to accounting
overview of bitcoin modern accounting
the current financial paradigm regards bitcoin, Ethernet and all other cryptocurrencies as assets. In the United States, for example, any form of cryptocurrency is considered property, not money. Although the IRS recognizes that bitcoin can be used as a "medium of exchange", bitcoin is not classified as currency because it usually has the function of "unit of account and value storage space"
as a result of this classification, changes in the value and quantity of cryptocurrencies are taxed as capital gains or losses. Mining or buying a lot of bitcoin will lead to capital increase, which will make bitcoin subject to capital gains tax. The same is true for trading or selling cryptocurrency, as these events are treated as taxable capital gains and losses. Therefore, the accounting treatment of the holding amount of the comparative currency or other high-end stocks is roughly the same as that of other forms of equity (such as real estate or stocks)
forecast of bitcoin and accounting in the future
e to the legitimacy of blockchain and cryptocurrency in the financial sector, the accounting nature of bitcoin and other advanced currencies will also change. Although many potential changes are too far away to be accurately predicted, one aspect of accounting is bound to change dramatically, which will inevitably affect all entrepreneurs and business organizations. This aspect refers to audit
here's how blockchain and cryptocurrency are used to brutally disrupt the audit process, and what it means for companies that employ auditors? Because bitcoin is currently classified as the property that must pay capital gains tax, the audit method of its value is called immediate forensics analysis. However, the immediate verifiability of blockchain technology makes this audit method obsolete

when you track these changes and developments, please discuss with your organization's accountant or financial advisor. They can help you understand the further meaning of these events; In some cases, they can even show you what actions you can take to deal with these events, so as to increase your profits, rece your costs, and open up a new development path for your enterprise
on the other hand, if your accountants and auditors are at a loss about your research, consider updating your finance team.

4. 1. Weizhong bank uses blockchain technology for loan clearing
in September 2016, Weizhong bank and Shanghai Huarui bank put into trial operation the inter-bank joint loan clearing platform based on alliance blockchain technology to optimize the settlement and clearing of "micro loan" joint loans of the two banks. With the introction of the blockchain system, all the information is recorded on the blockchain network, which can not be tampered with. The transaction process is cleared at the same time, realizing real-time clearing, saving a lot of manpower and material resources
2. China UnionPay uses blockchain technology to realize inter-bank points exchange
in September 2016, China UnionPay and IBM tried out a shared points system based on blockchain technology. Using this blockchain system allows users to exchange bonus points across banks and platforms. In other words, the bonus points of one bank can be exchanged for bonus points of other banks, or even multiple airline mileage and supermarket awards. It greatly improves the use efficiency of bank points
3. Toyota uses blockchain technology to track auto parts
in October 2016, Toyota joined R3 alliance to store the proction, processing and use of each part in the blockchain through blockchain technology, so that when there is a problem with auto parts, the source of the parts can be easily and quickly found
4. Central bank's blockchain digital bill trading platform
in January 2017, the central bank's blockchain based digital bill trading platform was successfully tested. The introction of digital currency for settlement can realize the synchronous transfer of capital flow and information flow of digital bill transaction, so as to realize DVP bill settlement. At the same time, the blockchain digital identity solution solves the problem of repeated KYC authentication between different financial institutions. It not only solves the problem that the transaction amount of digital bills is confidential to the unrelated parties, but also ensures that the regulatory parties such as the exchange have the mechanism of seeing through when necessary
5. Ant financial services blockchain application
in August 2017, ant financial services blockchain technology tested water insurance and helped Xinmei mutual insurance company to launch the first love rescue account in the domestic insurance instry. Blockchain technology makes every capital flow open and transparent, the data of every capital flow can not be tampered with, and the whereabouts and uses of every capital can be traced. In November of the same year, ant chain was used in food safety traceability and traceability of genuine procts. At present, the milk powder proced in Australia and New Zealand and Moutai in China, users can only know if they are genuine procts by scanning Alipay.
there are many other successful cases at home and abroad, all of which indicate that the application of blockchain technology is graally promoted, and is favored by various instries. Accompanied by the emergence of many blockchain technology companies, they want to take a share in this field. However, after the people's Bank of China and other seven ministries and commissions issued the "notice on preventing the financing risk of token issuance"), with the increasing difficulty of registration, there are more empty shell companies in the intermediary instry chain, and few companies have practical applications
in addition, the security technology of blockchain has always been concerned and controversial. Nowadays, blockchain mainly faces five security problems: the security of underlying code, cryptographic algorithm, consensus mechanism, smart contract and digital wallet.

5. 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.

6. There are many blockchain projects, and few of them have practical applications. The development of blockchain is still in the early stage of development! If you want to engage, you'd better understand the strength of the project party and the team's belief and attitude towards the blockchain
I learned about a project on the Internet before: akso health chain, which is engaged in blockchain health care project! Committed to solving the problem of health care data island! You can understand and pay attention to it (for reference only, no investment suggestions, thank you)

7. Yes, the central network is authentic. Investment is sure to make money.

8.

Layer 2 is concerned with the protocols on the chain and off the chain. It is mainly responsible for the message passing, intelligent contract programming and application related functions on the chain and off the chain. That is, the auxiliary framework or protocol built on the existing blockchain system (layer1). If we use the analogy of legal structure, layer1 is like the constitution, which is the basis of all laws. The formulation of laws cannot violate the constitution

by layer 2 protocol, the "state generation" of blockchain transactions can be independent of layer 1, so these protocols can also be called "off chain" expansion schemes. One of the main advantages of using the offline expansion scheme is that it can rece the limitations of layer1 and does not need to change the protocol of the blockchain itself. The layer2 expansion scheme achieves high-throughput state generation without sacrificing the security of the blockchain network

extended data

application direction:

1. Payment: for example, in terms of time, traditional cross-border remittance takes 10 minutes or several days, while blockchain cross-border remittance, e to decentralization, can achieve remittance in seconds. In terms of convenience, traditional cross-border remittance needs to wait until the next day after 19:00, while blockchain cross-border remittance only needs one mobile phone to realize all-weather remittance

2. Sharing medical records: the medical data blockchain sharing platform can achieve many application scenarios. Patient history data and other information can be linked, and medical history and image data can be viewed by personnel entering the system. These medical data can also be used for modeling and machine learning
