Case study on the combination of blockchain and Finance

1. 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.

3. Voice of the Century Group has cooperated with Jiajin He technology company to complete the development and application of the latest global traceability tracking system for wangbingqian Jingui liquor, wangbingqian Honggui liquor and wangbingqian langui liquor. And on the ant financial services blockchain, it can be tracked and inquired all over the world
the voice of the century is dedicated to building an integrated intelligent packaging and digital marketing service scheme for Wang Bingqian liquor, which comprehensively promotes the proct upgrading and brand upgrading of Wang Bingqian liquor from packaging enabling, traceability data collection on the blockchain, Beidou Positioning origin fidelity, AR digital interactive marketing to new retail building. Enabling the packaging of Wang Bingqian liquor is the basis for its procts to move towards intelligent and digital application. Since then, Wang Bingqian liquor has established a connection mechanism with mobile Internet, Internet of things and cloud big data, and began to enter consumers' smart phones, guiding consumers from the physical world of procts to the virtual world of procts, thus solving the problem of anti-counterfeiting traceability, anti-counterfeiting and anti-counterfeiting Quality tracking, anti fleeing, digital marketing, brand communication, new retail and other needs.

4. No,

5. Because the digital currency, which is the first generation of blockchain technology, has a huge impact on the financial field, the research and application of blockchain technology has become an important task in today's financial field. In essence, blockchain technology still belongs to a kind of technical means and tools. Its application in the financial field and the real economy is parallel. It has its own relative independence, but it also has a certain degree of intersection. That is to say, its role in promoting the real economy is indirect. 1. No matter in finance or entity, one of the bases of transaction between supply and demand is trust. The current bank to enterprise, enterprise to enterprise and enterprise to person are all linked by money. With the further popularization and wide application of blockchain technology, enterprises and enterprises, or indivials can issue digital currency (Digital credit) by themselves in the future, and the status of banks will change from monopoly operation to equal competition operation in the market. Therefore, the wide application of blockchain technology in the financial field has an indirect impact on the real economy. 2. Blockchain technology is the bridge between reality (entity) and virtual world. Through blockchain technology, the real world can be reconstructed, reconstructed and redefined in the virtual world. For example, the digital currency of real paper money in the virtual world, the digital stock transaction of real stock transaction in the virtual world, the digital settlement, digital customs clearance, digital documents and bills of real import and export trade in the virtual world can greatly improve the efficiency of business process and save the transaction cost. At present, all transactions are inseparable from the bank. The bank plays a central role in the transaction. The application of blockchain technology by the bank will certainly improve the efficiency of its settlement and indirectly promote the efficiency of the real economy, but this impact will graally weaken in the future. Because the biggest feature of blockchain technology is decentralization, its distributed accounting system is a network system without center. 3. In fact, the application of blockchain technology is to value and credit the information flowing on the Internet. Through the blockchain, the information with (use value, exchange value, cultural value) in the Internet is reorganized and newly constructed to form a value Internet. It is of great significance. It will bring revolutionary promotion to both the financial instry and the real economy.

6. The main advantages of blockchain technology in the financial field are disintermediation and cost rection. First of all, e to the prevention of single point of failure and systemic risk, the financial instry needs to carry out layer upon layer audit to control the financial risk, but it also causes high internal costs. Blockchain technology can greatly rece the cost of the entire financial system through tamper proof and high transparency. There is a lot of blockchain related information in the chain broadcast. You can have a look if you are interested.

7. There are many applications of blockchain technology in the financial field. To give a few simple examples:
the people's Bank of China launched the trade finance blockchain platform, which widely connects the information of tax, customs, foreign exchange and other departments, and effectively helps the financing and credit enhancement of small and medium-sized enterprises
Guangdong has released the first local financial off-site supervision blockchain system in China, which can effectively solve the problems of information asymmetry and unreliability between financial institutions and regulators in traditional supervision methods
State Grid supply chain financial data sharing platform based on data side chain: provide conditional and reliable sharing service of supply chain financial data under privacy protection, help small and medium-sized suppliers to revitalize accounts receivable, rece financing cost and increase financial income of financial institutions
in addition to these, there are other applications, such as cipher finance mimacaijing, which focuses on blockchain information.

8. The first is definitely because of policy support. Most of the blockchain instrial parks are dominated by the government. The second is the participation of local enterprises, including capital and technology. The third is to have blockchain application projects that can be supported. Changsha high tech Zone also has a blockchain Instrial Park. Now it has launched a SMIC blockchain service platform project, It is also a blockchain application landing project.
