Blockchain is responsible for storage and clearing
Publish: 2021-04-27 23:10:39
1. In short, the data of the blockchain is formally stored in the blockchain through the formula algorithm process of the block. All nodes in the whole network express that they accept the block, and the way to express acceptance is to make the random hash value of the block the latest block hash value. Xingqun manufacturing will be extended based on the blockchain.

3. The information of each block in the blockchain is different, and the generation time and recorded data of each block are different. You can regard the blockchain as a bookkeeping book. Every once in a while, someone will write all the transaction information on the blockchain network to one page of the ledger, page by page, and record all the transactions on the blockchain network in turn according to the time
on the other hand, all nodes (computers in short) participating in the network will store one account book, which is updated in real time. Even if one node fails, the blockchain will not be affected.
on the other hand, all nodes (computers in short) participating in the network will store one account book, which is updated in real time. Even if one node fails, the blockchain will not be affected.
4. Cloud computing storage can be used as the lower layer of blockchain. Cloud computing or cloud storage is infrastructure, which can be understood as a new generation of computer (or hard disk), while blockchain can be seen as a business oriented accounting system (or a trusted database) that can be built based on Cloud Computing (cloud storage).
5. The relationship between blockchain and big data storage is as follows:
first, data security: blockchain makes data flow "at ease"
with its trustworthiness, security and non tamperability, blockchain liberates more data. 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< Second, data open sharing: blockchain guarantees data privacy
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< The schematic diagram of data hash desensitization processing
3. Data storage: blockchain is a kind of database storage technology that can not be tampered with, full history, strong endorsement
blockchain technology, through all nodes in the network participate in the calculation together, and verify the authenticity of their information to achieve the consensus of the whole network, it can be said that blockchain technology is a specific database technology. 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< Data analysis: blockchain ensures data security
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
v. data circulation: blockchain protects the rights and interests related to data
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, making clear the source, ownership, use right and circulation path of big data assets, which is of great value to data asset transaction
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 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. Blockchain is one of the most challenging innovations in the field of fintech, because blockchain fundamentally subverts the inherent logic, operation mode and business scope of traditional finance, breaks through the limitations of numerous conventional rules and regulations, and steps into a series of new application fields that cannot be involved before
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

7. Big data and blockchain are two independent things, which do not have to be used
in fact, only high-level security data can be used for blockchain development, and most companies do not have this requirement. It can be understood that there are so many companies in the world, only a small part needs to use big data technology, and a smaller part needs to use blockchain technology. These two parts can intersect but do not include
for companies that normally use big data, there are non relational databases like HBase, mongodb, hive, Mr, spark and so on in terms of storage and processing, which have nothing to do with blockchain.
