Credit management blockchain

1. 1. At the international summit on blockchain held from September 23 to 24, 2016, Ma Zhitao, vice president and chief information officer of Weizhong bank, disclosed that Weizhong bank and Huarui Bank jointly developed a blockchain application system, which can be used for the settlement and clearing of micro loan joint loans of the two banks. The system has been put into trial operation in September. After the introction of the blockchain system, because all information is recorded on the blockchain network and cannot be tampered with, the transaction process is accompanied by the liquidation process, which can complete real-time liquidation< On September 23, 2016, IBM and China UnionPay previewed the "inter-bank points exchange system using blockchain technology", which allows consumers to exchange bonus points across banks and platforms. The points of one bank can be exchanged for bonus points of other banks, and even for mileage of several airlines and supermarket rewards, The system can greatly improve the efficiency of bank points. Take the point exchange as an example. Traditionally, consumers take away goods after exchanging points, but merchants need to prove the user's points and settle accounts before they can finally complete the transaction. The blockchain can link all the credit perfectly. The original trust process and cost that rely on the third party can be removed, and the transaction is settlement
3. The central bank's blockchain digital bill trading platform
in early 2017, the people's Bank of China's blockchain based digital bill trading platform was successfully tested, and then the digital currency Research Institute of the central bank will be officially listed. The people's Bank of China has become the first central bank to study digital currency and its real application
the central bank's blockchain digital bill trading platform introces digital currency for settlement, which 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, through the blockchain digital identity solution, the problem of repeated KYC authentication for users between different financial institutions is solved.

2. The entry threshold of virtual currency is the lowest, which is relatively reliable. Choose regular exchange hot currency or okex. Leverage trading of foreign exchange futures is very risky. The stock market is not perfect and has little investment value at present.

3. China's credit instry is mainly based on enterprise credit, while personal credit needs to be developed, and the overall market prospect is broad. China's enterprise credit development is early, and the market is relatively mature. By the end of 2016, there are about 137 enterprise credit reference institutions in China. Personal credit has not yet been put into market operation and the license has not been issued yet. Eight units, including Tencent credit, sesame credit, Qianhai credit, lakara credit, Zhongcheng credit, zhongchengxin credit, PENGYUAN credit and Hua credit, have participated in the personal credit pilot organized by the central bank. Private personal credit institutions can indirectly participate in the personal credit market through cooperation with banks and other financial institutions, but they can not directly publish personal credit reports. To obtain personal credit reports, they can only go through the central bank credit system. As of the end of June 2016, the central bank's credit reference center has included 21.2 million enterprises and other organizations and more than 900 million natural persons, of which only 5.77 million have credit records with 410 million natural persons. The data of Experian, a global credit giant, has covered 103 million enterprises and 890 million people in the world. Compared with the market demand and credit market scale of the United States, the future development space of China's credit market is huge

the emergence of blockchain technology has become a good medicine to understand the pain points of credit reference instry. Through the characteristics of authenticity, transparency and non tampering, blockchain technology can solve the problems of trust and data sharing between credit agencies, so as to solve the problems of data island and incomplete data. Through the establishment of an alliance chain, first of all, the problem of data right confirmation can be completely solved. In an alliance chain system, credit reference institutions, users, government departments, financial institutions and other relevant units in the chain can be added, and different access rights can be designed to ensure the ownership of data, open up information sharing, and protect data security from theft and leakage

on this basis, the channels for credit agencies to obtain data are greatly widened, which can save the cost of data collection; At the same time, the cooperation between different organizations has become more smooth, recing the cost of cooperation and communication. Credit agencies can put the saved costs into other links to improve the overall quality of procts<

Based on providing diversified growth paths for students, the professional station promotes the reform of the training mode of the combination of professional degree research, proction, learning and research, and constructs the applied and compound talent training system.

4. The relationship between blockchain and big data storage is as follows: first, data security: blockchain makes data flow "at ease". Blockchain liberates data with its trustworthiness, security and non tamperability. A typical case is used to illustrate how blockchain promotes the generation of big data for gene sequencing. Blockchain sequencing can use the private key to limit access rights, so as to avoid the legal restrictions on indivial access to gene data, and use distributed computing resources to complete the sequencing service at low cost. The security of blockchain makes sequencing an instrialized solution, realizing global scale sequencing, thus promoting the massive growth of data. 2、 Data open sharing: blockchain guarantees data privacy, and the government has a large number of high-density and high-value data, such as medical data, population data, etc. The opening of government data is the general trend, which will have an inestimable impetus to the development of the whole economy and society. However, the main difficulty and challenge of data opening is how to open data while protecting personal privacy. Data desensitization technology based on blockchain can ensure data privacy and provide a solution for data opening under privacy protection. Data desensitization technology mainly uses hash processing and other encryption algorithms. For example, enigma based on blockchain technology can protect the privacy of data and eliminate information security problems in data sharing by computing data without accessing the original data. For example, employees of a company can safely open the path to access their salary information and jointly calculate the average salary within the group. Each participant can know his or her relative position in the group, but he or she knows nothing about the salaries of other members. Schematic diagram of data hash desensitization processing 3. Data storage: blockchain is a kind of database storage technology that can not be tampered with, with full history and strong endorsement. It can be said that blockchain technology is a specific database technology by all nodes in the network participating in the calculation and verifying the authenticity of their information to reach a consensus of the whole network. So far, our big data is still in a very basic stage. The data based on the consensus of the whole network and the reliable blockchain data are tamperable and historical, which makes the quality of the data gain unprecedented strong trust endorsement, and also makes the development of the database enter a new era. 4、 Data analysis: blockchain ensures data security, and data analysis is the core of realizing data value. In data analysis, how to effectively protect personal privacy and prevent core data leakage has become the primary consideration. For example, with the application of fingerprint data analysis and the popularization of genetic data detection and analysis, more and more people worry that once personal health data is leaked, it may lead to serious consequences. Blockchain technology can prevent this kind of situation through multi signature private key, encryption technology and secure multi-party computing technology. When the data is hashed and placed on the blockchain, the use of digital signature technology can enable those authorized people to access the data. The private key not only ensures the privacy of data, but also can be shared with authorized research institutions. The data is stored on the decentralized blockchain and analyzed without accessing the original data. It can not only protect the privacy of the data, but also provide it to the global scientific research institutions and doctors for sharing. As the basic health database of all mankind, it will bring great convenience to solve the sudden and difficult diseases in the future. 5、 Data circulation: blockchain guarantees data related rights and interests. For valuable data assets of indivials or institutions, blockchain can be used to register them. Transaction records are recognized, transparent and traceable throughout the network. It defines the source, ownership, use right and circulation path of big data assets, which is of great value to data asset transactions. On the one hand, blockchain can break the threat of intermediary ing data, which is concive to the establishment of a trusted data asset trading environment. Data is a very special commodity, which is essentially different from ordinary commodities. It is mainly characterized by unclear ownership and "being owned after seeing and ing", which also determines that the traditional commodity intermediary transaction method can not meet the needs of data sharing, exchange and transaction. Because the intermediary center has the conditions and the ability to and save all the flowing data, it is extremely unfair to the data procers. This threat can not be eliminated only by commitment, and the existence of this threat has become a huge obstacle to the flow of data. Based on the decentralized blockchain, it can break the threat of ing data in the intermediary center and protect the legitimate rights and interests of data owners. On the other hand, blockchain provides a traceable path, which can effectively solve the problem of data right confirmation. Through multiple nodes participating in the calculation in the network, blockchain can participate in the calculation and recording of data together, and verify the effectiveness of their information. It can not only carry out information anti-counterfeiting, but also provide a traceable path. The transaction information of each block is strung together to form a complete detailed list of transactions. The context of each transaction is very clear and transparent. In addition, when people have doubts about the "value" of a block, they can easily trace back the historical transaction records, and then judge whether the value is correct, and identify whether the value has been tampered or recorded incorrectly. With the protection of everything on the blockchain, big data will naturally become more active. The tokens of crowdfunding projects on coin Ying China platform are all developed based on blockchain technology, and relevant information will be recorded on the blockchain.

6. The blockchain itself does not evaluate anyone's credit, but only supports the deposit of transaction records, transaction data and information on the Internet. In other words, all the information stored on the blockchain is authentic and can be recognized by all the nodes in the network. On the one hand, it can ensure that the credit image of the credit informant can be relatively transparent, and that he is identified with it; For credit informants, the transparency of the working process can also be convincing. In this way, we can make the results of Internet credit investigation, rece differences and angle deviation, and more accurately apply to some specific transaction process. In addition, the high credibility of the credit results will make the cost of breaking the law higher.

7. Long term practice in the blockchain instry has made Xu Mingxing understand blockchain more thoroughly. In Xu Mingxing's view, one of the important manifestations of modern commercial development is the expansion of trust, and the centralized trust intermediary also brings huge trust costs. The development of blockchain technology has brought a good solution to rece the cost of trust. In this context, it is more and more important to promote the development of blockchain instry and help upgrade the modern enterprise credit system. Therefore, the credit information system should be the social infrastructure.

8. For example, a credit reference institution can use big data to collect information on the Internet to see more specific and detailed things, such as identity information, what kind of business or financial transactions have been carried out in what kind of place, and then use this information for credit reference. There is a hidden danger here, the credit reference personnel can take these confidential information to do some illegal and illegal things in private. After the intervention of encryption and anonymity of blockchain technology, the same data can process and analyze the traces of the parties in the network, without directly presenting these details to the collectors. In other words, the way of grabbing is different, background automation, and human isolation for processing.

9. There should be contacts. It is said that more than 30000 enterprises will register information on the first phase of the public service platform of SMIC blockchain. It seems that enterprises can check each other's basic information through the secret key of the exclusive blockchain, which can rece the credit risk caused by information asymmetry when concting business cooperation. This is actually equivalent to the credit system of enterprises.
