Credit card blockchain
As a traditional financial institution, banks are the most active Pathfinder in the field of blockchain. In recent years, many banks at home and abroad have applied blockchain technology to credit, clearing and other fields. The unique trust mechanism of blockchain is regarded by banks as a key technological breakthrough in innovating risk management and simplifying transaction process. However, as an emerging technology, blockchain ecology is still in the process of establishment, and its application is very limited. Many problems still need to be solved graally in the development
"at present, blockchain can't run high-frequency and concurrent transactions, and network speed and computing power can't support it. For example, in the field of payment, if it is online shopping, it can be realized; If it's high-frequency futures trading, it can't be done. " Huang Zhen said
JIANG Peng said that at the beginning of designing the blockchain system, China CITIC Bank carefully demonstrated the business links suitable for the use of blockchain
"from the global experience, it is not suitable to use blockchain to build a large and complex system. Instead of trying to solve all problems with blockchain, we should focus on solving the core problems. It's time-consuming to build a too complex system. The technology is developing so fast that before the old system is finished, it will face the iteration of new technology. " Jiang Peng said
the idea of "only solving core problems" ensures that after the blockchain goes online, the relevant business operations of branches of China CITIC Bank can be upgraded without process transformation
Fan Bin said frankly that it will take time for banks to fully apply the blockchain, and IBM's investment in the blockchain open source community will continue, on the one hand to cultivate the market, on the other hand to compete for the commanding height of the blockchain platform. With the rapid iteration of blockchain technology itself, there is still a lot of imagination for financial institutions to use this new technologythe content comes from Xinhuanet
as a disruptive technology, blockchain will reconstruct the key infrastructure of Internet Finance and even the whole financial instry, and its value in the financial field is waiting for people to discover. Specific applications are as follows:
first, the application of banking instry
wallet and payment are the first fields of blockchain technology, but this is also the traditional business scope of banking instry. What changes can blockchain technology bring
cross border payment application case:
circle, founded in October 2013, aims to make bitcoin "simple and easy to operate, similar to Gmail (Google Mail), Skype (Microsoft's Internet phone) and other customer service tools", and quickly obtain a large amount of financing. In mid-2014, it obtained an investment of US $27 million, becoming one of the most well funded companies in the field of digital cryptocurrency
in 2015, Goldman Sachs and IDG Capital Partners led the investment and raised $50 million for circle. In June 2016, circle won US $60 million of investment led by Chinese investors, and announced that it has established an independent company circle China in China and set up a local team to reach strategic cooperation with network and Everbright
circle can provide instant and free fund transfer worldwide by using bitcoin blockchain transaction. Circle hopes to use bitcoin as a free internet payment network, so that the legal tender of each country can flow smoothly around the world without hindrance. By working with overseas companies such as IDG, circle can provide financial services to users of national legal tender
although the regulatory structure of payment systems in various countries is complex, the cooperation between these countries has made progress. In April 2016, circle obtained the first e-money license issued by the financial conct authority (FCA), which aroused widespread concern in the instry. Later, circle announced that it had established a partnership with the Bank of Barclays to enter the UK market. Since then, British consumers can enjoy services such as fast transfer payment and buying and selling bitcoin, just like American consumers
in order to make it easier for users to use, circle cooperates with apple. In IOS 10 system, Apple's IMessage supports users to use circle's bitcoin payment system. Jeremy Allaire, chief executive officer of circle, said:
"if IMessage allows access to payment service, consumers will benefit from it. It is difficult to install an app alone for payment, and the transfer payment behavior between friends has to go through a complicated setting process, but it is much simpler to directly access to IMessage service."
on September 13, 2016, circle announced that users can pay anyone in the world through IMessage
advantages of blockchain in cross-border payment: low cost, real-time transaction and high security
intelligent bill application case:
the bill of complex us blockchain bill project and blockchain technology can be well combined. After adopting the decentralized distributed ledger of blockchain, the existing system storage and transmission structure has been changed, a more secure operation mode has been established, and the problem of forged bills has been solved
the time stamp reflects the whole process of bill from its birth to its demise, which has the characteristics of traceable history, so that this mode has a new continuous endorsement mechanism, and truly reflects the transfer process of bill rights
the domestic Hangzhou complex us blockchain Research Center has also initially developed an open source project of blockchain lending bill exchange based on Ethereum, which integrates the concept of using blockchain technology in many subdivided fields such as finance, catering, enterprise management, express tracking, etc. The open source project of complex us blockchain online lending bill exchange is shown in the figure. The online lending exchange applying blockchain technology can complete 150000 transactions per second without handling charge
the bill business based on blockchain has four advantages:
from the perspective of moral hazard, the phenomenon of "selling more than one ticket" in paper tickets and the phenomenon of asynchronous payment and endorsement in e-bills occur from time to time. However, e to the characteristics of time stamp that can not be tampered with and the whole network is open, there will be no default once the paper tickets or e-tickets are traded
from the perspective of operational risk, as the e-bill system is centralized, once the central server fails, it will have disastrous consequences for the whole market. At the same time, the access of enterprise online banking will transfer the risk to the bank's own network security, and the whole risk chain will be longer and longer. With the help of the distributed high error tolerance and asymmetric encryption algorithm in the blockchain, the risk of human operation will be almost zero
from the perspective of credit risk, with the help of blockchain data, we can collect and evaluate the credit of all participants, and control them in real time
from the perspective of market risk, a large number of asset mismatches in the intermediary market not only lead to their own losses, but also bind the interests of banks. With the programmability of blockchain, it can not only effectively control the balance between the asset side and the liability side of participants, but also promote the authenticity of the reaction of the transaction price of the whole market to the capital demand with the help of the characteristics of data transparency, And then form a more real price index, which is concive to control market risk
bank settlement - Application Case: visa
bank settlement refers to the collection and payment behavior realized through the fund transfer of bank account, that is, the bank accepts the client's entrustment to collect and pay on behalf of the client, transfers the money from the deposit account of the payer to the deposit account of the payee, so as to complete the settlement of creditor's rights and liabilities or the allocation of funds between the clients. In this process, the bank is not only the medium of commodity exchange, but also the intermediary of clearing funds in social and economic activities
unlike domestic banks, which mainly rely on the difference between deposit and loan, half of the profits of multinational banks come from the intermediate settlement business. For them, if they open up new business areas and reasonably rece the settlement cost, it is directly related to their fundamental interests
visa is the largest credit card company in the world. There is no doubt that the rise of digital cryptocurrency will inevitably impact its credit card payment business. However, visa does not always conflict with e-money and blockchain, but takes an open attitude
in October 2015, visa and DocuSign jointly launched a "proof of concept" project, which uses bitcoin blockchain to record and keep car rental data. The project combines DocuSign's digital transaction management (DTM) platform and electronic signature solution with visa's secure payment technology. Consumers can configure rental, insurance and other daily purchase items in the car, such as parking fees and tolls, and users can pay directly with visa card
peripheral applications do not satisfy visa. In the same year, visa cooperated with coinbase to launch the first bitcoin debit card that can be used in the United States. On November 30, at the unbound conference held in London, visa European innovation laboratory showed another "proof of concept" remittance application, through which people can remit money on the bitcoin blockchain
in September 2016, visa launched interbit, an interbank settlement and payment system based on blockchain technology, in cooperation with BTL group, a digital payment start-up company, to assess whether blockchain technology can rece the cost, settlement time and credit risk of interbank international transfer
a series of major actions in the past two years show that visa has begun to realize the value of blockchain technology and is making efforts to make blockchain technology a powerful tool to expand its sphere of influence
advantages of blockchain in bank settlement: security, convenience and intelligence
in addition to using blockchain technology to transform the existing businesses, banks around the world have launched their own cryptocurrency plans to rece their operating costs
the advantage of blockchain in bank digital cryptocurrency: cost rection< Second, securities investment market application
Securities Trading - Application Case: LINQ
securities trading market is an important application field of blockchain. The application of blockchain technology can not only speed up the speed of clearing and settlement, but also rece the number of books that financial institutions need to maintain to ensure more accurate audit tracking
NASDAQ is the first person to eat crabs in the stock market. In the second half of 2015, it launched the trading platform LINQ, which is based on bitcoin trading technology and is used for trading companies in the primary market. As shown in the figure below, LINQ has the ability to record the equity transactions of enterprises before IPO, track the equity transactions of enterprises, information of shareholders and investors, etc., which is of great value to the asset analysis of private equity market
Fredrik Voss, head of NASDAQ blockchain strategy, is convinced that the high efficiency provided by blockchain technology will greatly enhance LINQ's advantages as a private equity trading platform. So far, no technology can really keep people away from paper work, and blockchain technology will make it a big step forward. Compared with manual processing, it will greatly rece the possibility of errors
advantages of blockchain in Securities Trading: speed up settlement, simplify accounts, and facilitate follow-up audit
equity crowdfunding - Application Case: ant
all along, capital is a gap in front of creative ideas and entrepreneurship, and it is this gap that spawned the world's first crowdfunding platform KickStarter. The operation mode of KickStarter is a typical business model of the platform. On the one hand, the users of the platform are those who are eager to create and create, on the other hand, those who have part of the funds and are willing to provide financial support for new ideas. The common wish of both sides is that the new ideas can be realized and can be promoted continuously
the crowdfunding platform based on blockchain technology can raise funds by creating its own digital cryptocurrency or digital assets, and distribute its own "digital equity" to early supporters, which is the certificate for investors to obtain shares in support of start-ups
blockchain crowdfunding platform usually consists of three layers:
the bottom layer is blockchain network, which constructs a decentralized distributed platform
the middle layer is the combination of business logic and blockchain to jointly establish account center, equity registration, equity voucher, equity trading, equity management and other functions
the top tier provides services for customers of various crowdfunding platforms
in China, Xiaoyi is the first company to use blockchain technology to register its equity. Although this is an innovation, it is not easy to achieve the legal compliance and docking with the real world in the underlying logic and various details. After in-depth study and analysis of the current legal environment in China, termite has the potential to become a practical blockchain application
termite is a blockchain protocol based on blockchain technology, which registers, issues, manages and trades various equity shares through point-to-point network. At the beginning, it will be
