Blockchain transformation of shopping malls
technical personnel can learn this technology, while non-technical personnel can start from the instry media and instry community
If an enterprise needs to develop blockchain applications, it can entrust a professional third-party company. In Guangzhou, today's technology is good.
financial field
blockchain has great potential application value in international exchange, letter of credit, equity registration, stock exchange and other financial fields. The application of blockchain technology in the financial instry can save the third-party intermediary link and realize the point-to-point direct docking, so as to greatly rece the cost and quickly complete the transaction payment
in the field of Internet of things and logistics, blockchain can also be naturally combined in the field of Internet of things and logistics. Through blockchain, we can rece logistics costs, trace the proction and delivery process of goods, and improve the efficiency of supply chain management. This field is considered as a promising application direction of blockchain
in the field of public service
blockchain is closely related to people's proction and life in the fields of public management, energy, transportation, etc., but the centralization of these fields also brings some problems, which can be transformed by blockchain. The decentralized and fully distributed DNS service provided by the blockchain can realize domain name query and resolution through the point-to-point data transmission service between nodes in the network. It can be used to ensure that the operating system and firmware of an important infrastructure have not been tampered with. It can monitor the status and integrity of the software and detect bad tampering, And ensure that the data transmitted by the system using the Internet of things technology has not been tampered with
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. After the works are confirmed on the blockchain, the subsequent transactions will be recorded in real time to realize the full life cycle management of digital rights, and can also be used as a technical guarantee in judicial evidence collection
in the field of insurance
in terms of insurance claims, insurance institutions are responsible for fund collection, investment and claims settlement, and often have higher management and operation costs. Through the application of smart contract, there is no need for the applicant to apply or the insurance company to approve. As long as the claim conditions are triggered, the automatic claim settlement of the policy can be realized
public welfare
the data stored on the blockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios. The relevant information in the public welfare process, such as donation project, collection details, fund flow, recipient feedback, etc., can be stored on the blockchain, and can be made transparent and public, which is convenient for social supervision
the second is that only mature technology is not enough. In order to realize a large number of DAPP and commercial applications on the blockchain, we must be prepared on one hand: that is, the digital currency that can be used as payment tool, exchange medium, value measure and value storage. Xiao Feng said that everyone thinks that bitcoin is a payment system, but the real bitcoin can not meet our demand for payment because its currency value fluctuates too much
for example, he said that a mall sold a bottle of water and accepted bitcoin payment. When he got up the next morning, he found that 20% of the value was gone. So it can't be accepted. After the Japanese parliament made it clear that bitcoin could be used as a payment tool, some Japanese businesses announced that they would accept bitcoin payment. But later found that it caused a lot of trouble for the stability of the company's balance sheet. Your balance sheet is unstable, up or down. This not only affects the value of the things sold, but also affects the credit evaluation of enterprises and the services provided by banks to companies
the third condition is the construction of laws and regulations and supervision system. The digital economy on the blockchain must obtain legal protection and comply with the law. Xiao Feng stressed that there can be no decentralization in this regard
the differences between blockchain and Internet are discussed. He believes that the core difference between the two is that the Internet is a centralized trust mechanism, while the blockchain is a decentralized trust mechanism, and there is no need to trust a third party
the second core difference between the Internet and blockchain is the incentive mechanism, not the digital currency or the ability to issue currency. Economics has been discussing incentive incompatibility. Under the company system and on the Internet, the incompatibility of incentive mechanism has not been solved. However, in the decentralized blockchain, the blockchain achieves complete incentive compatibility. Without shareholders, board of directors and employees, the conflicts of interest between these roles will not happen again.
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
Although the current blockchain technology is still in the initial stage, the advantages of this technology have begun to be reflected. In many fields, blockchain can proce great value, and I believe there will be more landing application scenarios in the future,
blockchain + cross border payment
at present, the mainstream way of cross-border remittance is wire transfer, and its cycle is generally as long as three to five working days. In addition to certain handling charges, intermediary banks will charge certain handling charges, Swift (Global Interbank Financial Telecommunication Association) will also charge a higher fee for the message exchange of its system. In China, a single fee of 150 yuan will be charged for cross-border remittance through the Bank of China
and the use of blockchain technology allows the remitter and the payee to pay and settle directly, eliminating all intermediate costs, so that cross-border payment and settlement can be completed point-to-point quickly. While improving the speed of settlement, it can also achieve all-weather payment, real-time arrival, simple embodiment and no hidden cost
Specifically, users can share the idle storage space and bandwidth resources of cat disk, and these resources will be output to companies such as content, video, game, blockchain, etc. cat disk company will convert the legal currency and various digital currencies paid by the latter into bitcoin, and users will get the corresponding bitcoin income. This is also the unique mining mode of cat disk
why reward bitcoin
because similar procts on the market reward users with points, diamonds and other rights and interests issued by relevant companies, and most of these rights and interests are of low or no value. In addition, those projects that once seemed to be hot are now almost withered, and the early players may benefit, while the late players will lose all their money
as we know, bitcoin is the anchor currency in the digital currency world. Cat disk directly uses bitcoin to motivate users, and users can pick up the coin to their wallet at any time, and their income can be guaranteed. Moreover, the risk of bitcoin breaking is almost zero, and the user's income will be more lasting and stable
how is the mining income distributed when it comes to distribution, we should first introce the concept of "storage power", which is directly linked to the income of cat disk users. Storage power is an index based on users' shared storage space, bandwidth and online time. The larger the storage space, the faster the bandwidth speed and the longer the online time, the larger the storage power, and vice versa the cat disk gains revenue by sharing storage bandwidth resources, and users can check the revenue through app every day, that is, how much bitcoin they earn. The profit distribution of maopan mining is not random, but through a series of calculations. In short, users' daily income depends on their personal storage capacity, all users' storage capacity and the amount of money issued each day. The calculation formula is as follows: single user's daily income = single user's daily storage capacity / all users' daily storage capacity * Daily currency amount it can be seen that users' daily income is positively correlated with the daily storage capacity index and the daily currency amount, and negatively correlated with all users' daily storage capacity index what is the amount of money issued every day the cat disk integrates the storage and bandwidth resources shared by users, provides storage and bandwidth services to the demander, and converts various digital currencies paid by the other party into bitcoin for distribution to users. How much bitcoin is issued every day depends on the actual business situation, so there is no way to give specific figures for the time being. What we can make clear is that, unlike other mining procts, cat disk does not issue its own currency or restrict the mining of a specific kind or several kinds of currency. Instead, it earns various digital currencies paid by others. These currencies are all market currency. Cat disk converts these currencies into bitcoin and distributes them to users note that all the currencies are negotiable, and the more storage nodes, the more business, the higher the overall mining revenue; For other mining procts, the amount of money that can be mined is limited or issued by the owner. With the passage of time, there will be more and more mining machines, and the mining income will be less and less

that's the level.
the chain reform is to use the blockchain technology and economic model to transform the traditional economic form of enterprises or institutions, optimize and upgrade the original business model, proct model, incentive system and user system by using the characteristics of the blockchain, such as decentralization, consensus mechanism, tamper proof, traceability and encryption algorithm
