Ⅰ Blockchain "token" will subvert "capital"

Blockchain brings an opportunity that comes only once in 500 years. Because what it changes is not productivity, but production relations.

A person works for a company 8 hours a day. Does he have to work for a company in the future? Is it possible to be self-centered rather than company-centered? This is what blockchain technology brings us to think about.

Most people think of blockchain as a new technology, some say it is a new generation of the Internet, and some call it the digitization of currency or assets. The author believes that what blockchain is facing is to subvert the entire social relationship and social organizational form. It is a manifestation of the development of productivity to a certain stage. The Internet has brought about a great development of productivity. The previous production relations have no longer adapted to the development of productivity levels, and have even hindered the development of productivity. The exchange of new productive forces and the birth of new production relations are the token economy brought about by blockchain technology. Its impact is much more profound than the blockchain technology itself.

Previous capitalist reforms all focused on capital, and tokens will subvert the economy and even capital. The original modern company organization method of capital structure with raised funds as the core will be subverted by the future economic organization method of token structure with contribution incentives as the core. The capital economy will be subverted by the token economy, and capitalism may be subverted by tokenism.

Reshaping human organizational forms, business organizations, and corporate systems can be regarded as the greatest invention of capitalist society in the past few hundred years. It can be said that without the company, there would be no history of Britain becoming an empire on which the sun never sets, and there would be no strong rise of the United States. But as the company has developed over the years, problems have also emerged.

Labor creates value, but workers do not enjoy value, that is, those who create value do not enjoy value, and those who enjoy value do not create value. For example, in Taobao, value is created by executives, employees, consumers, distributors, and suppliers, but those who truly enjoy value are those who invest in the capital market.

The author believes that it is time for humankind’s organizational and economic forms to be reshaped. In the past, when running a company, as long as it raised funds, it could hire more people, buy more production materials, and expand reproduction. In this era of fragmentation, entrepreneurs no longer need to rely on a lot of capital to start a business. They can also crowdfund to start a business. Even if you don’t invest any money, as long as your people contribute to the company, they can enjoy the value of the company. The organization of resources has changed: funds are no longer the most important, resources are the most important.

This organizational method is fully expressed by the blockchain. Wu Xiaobo mentioned a term called "entrepreneur": entrepreneur and investor. It is unimaginable that investors and entrepreneurs can be separated. All valuable things in the company are reflected on the balance sheet, including equipment, factories, and land., is the most valuable asset. Now data and users are the most valuable assets in the future, and they are not reflected in the balance sheet.

What has always been the case is that employees in the company receive salaries, executives receive incentives plus some options, channel dealers earn product price differences, and partners earn service fees. Now this logic has changed, and the source of value has been changed. In the past, the surplus value of labor was expropriated by capital. In the future, everyone should be a contributor and enjoy. A person has a variety of resources: human resources, knowledge resources, and governance resources. Everything is centered on the individual, not around the product or the company.

Blockchain subverts the company's core value - maximizing shareholders' interests, and also subverts the company itself.

Blockchain’s transformation of traditional companies is reflected in its fragmentation of production processes and data, which is exactly the opposite of many social organizations. In the past, in industrialized societies, business could only be done on a large scale because transaction costs were very high. Blockchain makes granular transactions possible, miniaturized and trustworthy. In the original exchange of capital flows, there must be a process of fund payment when signing a contract. After digital assetization, it can be automatically processed through smart contracts, and the company system faces various challenges.

In the future token economic structure, things that were originally considered valuable may become worthless, such as investors who form the basis of a company’s capital structure. and managers, company equity, assets, claims, capital, funds; the corporate governance structure that constitutes the company's organizational structure - shareholders' meeting, board of directors, management and employees; the accounting statements that constitute the basis of the company's financial system - costs, assets, liabilities , profit, income, depreciation, etc.

What the blockchain changes is not productivity, it changes production relations. The token system is a great invention. It is not a technology or a financing token, but a new organizational form and operation method that integrates all resources and value sharing. It is the next economic era. The "certification circle" will become a more sustainable circle with the influx of more traditional companies after the "Token circle", "chain circle" and "mining circle".

Token system reform: Token reform, chain reform, certificate reform

The chain is the skeleton, and the token is the soul. It can make a person and a community come alive. Everyone is a creator and value contributor, and everyone is an owner and enjoyer. This is the real meaning. However, the current token reform and chain reform claim to be decentralized and cannot be tampered with, but they still remain at the technical level. Technology will develop very fast in the future. This is not a problem that needs to be worried about. The biggest problem is whether the production relations have been adjusted. Just like as long as the company is established, financing and share reform are not problems.

The upper layer of the pass is Token reform, financing, ICO, and white paper, which has the function of financing and financial attributes; the lower layer is chain reform, blockchain technology, and distributionIt has technical attributes such as formal accounting, encrypted authorization, consensus mechanism, and smart contracts. They are interrelated and form a business logic, which is the core of the certificate. But now the upper and lower parts are separated. People who talk about chains call them chains, and people who talk about tokens call them tokens.

Certificate reform is the operating mechanism of a community. It is the sum of investment, production, distribution, exchange, consumption and other relationships, and has social attributes. It is not determined by the value of the chain, nor by how high the currency is speculated, but by the value of its own operation. The scope of tokens is larger than digital currency and blockchain itself. It is an adjustment of production relations when productivity has developed to a certain stage. Therefore, the future society may enter a token community organization, a token economy, or even a tokenism society.

The token economy is very important. It is the most important target tool for the future market. The economy undergoes fission, and the joint-stock economy turns to the token economy. Blockchain gives everyone a distributed account to manage and calculate people's value, thereby realizing the democratization of the economic system. Stocks are a certificate that distributes dividends based on equity. However, in the context of the digital economy, everyone's data has value. When participating in the distribution, a human value certificate - Token - appears, which is a human value certificate. Calculate using blockchain. This transformation changed the human distribution system so that everyone has the right to participate in distribution. Each person's big data is scientifically measured and essentially reflects a person's ability to create value. The token economy will take a big step forward in the civilization of human society, fully discover human value, better manage human value, and create more human value. Under this system, everyone has the right to freedom based on personal value, and there is no more exploitation and inequality.

To create value, tokens need to be issued through the blockchain. Only when the value of Token is stable can the certificate appreciate. Therefore, the transformation of the token system is a precise distribution and transaction model. Investors get certificates, producers get certificates, distributors get certificates, traders get certificates, and consumers get certificates. Balancing these five relationships requires accurate big data analysis to achieve a balanced and stable growth. mechanism. Therefore, certificate reform is not that simple. Chain reform is the participation of technology, Token reform is the preparation of white papers, and certificate reform can create core value. After centralization, the company is at the core, and decentralization is at the core of the token. A completely decentralized company has no value. Is the value of a fully centralized token zero? Does issuing Token mean the embodiment of real pass?

Many company forms will change in the future. Public companies, private companies, credit companies, market capitalization companies, and market capitalization management price-to-earnings ratios are actually issues we need to think about during the transformation of the token system. In the past, opportunities were once in 10 years, once in 30 years, and once in 100 years. Now they are once in 500 years. The author believes that blockchain is a very big opportunity. Instead of participating in the Token circle and the chain circle, it is better toCreate enterprises with real blockchain token value.

II Does blockchain have development prospects in the future?

A series of large companies such as Tencent and Alibaba are all trying to share and seize the blockchain cake. Do you think it has development prospects? Of course there is! Below are the top ten predictions of the China Academy of Information and Communications Technology on the global blockchain. I hope it will be helpful to you! !

< /p>

p>

From the current market media information, we can see that blockchain information has occupied the major media landscape. It is not an exaggeration to say that it is in the center of the storm. The appropriate metaphor is that it is in the center of the storm.

Why does the blockchain become so popular all of a sudden? Let’s talk about the currency circle. For example, a mainstream currency actually appeared a few years ago, but because the single value direction is not recognized by people, it is not It is worth entering the public eye. After several years of skyrocketing, it seems that some potential human nature has suddenly been activated. It is similar to buying a house. Everyone cannot understand it. It is tempting, explodes, and then activates greedy human nature. Then the information exploded all at once. Seeking knowledge is what everyone wants to know about how coins are produced and how coins are created. So this is how the term blockchain was discovered.

Back to the topic, there is a difference between the currency circle and the blockchain. The currency is just an extension of the blockchain, and the blockchain is the underlying development structure of the currency. Blockchain uses code architecture to build a data distribution architecture similar to a spider web. The information in each link is a storage node, which is different from the previous centralized information storage centers. If you want to modify one of the links, other storage information nodes do not allow it, and you cannot modify the underlying information. This kind of storage center Optimized information distribution is theoretically safer and has better information flow. Just like a house, the framework determines the layout of the house and the comfort of lighting. The principle of building the code architecture is also critical. The specific architecture of the blockchain There is currently not much reference information to what extent the utilization value can be achieved, but large companies have begun to make plans. Judging from the current popularity of the currency circle, the financial attribute field of blockchain is more attractive than other fields. .

The development prospects of the future blockchain are certain. If you want to understand the prospects of the blockchain field, you still need to have a deeper understanding of what the big guys in the current blockchain field are doing. For example, a certain investment giant What are V people doing using blockchain? The direction they are taking has set the benchmark for the development of this field to a certain extent.

I still advise that there are risks in certain coins, so do it and cherish it.

The prospects are great

Blockchain is known as the next generation of disruptive core technology, and some scholars believe it will redefine the world. Our government also supports blockchain technology. All its codes are transparent and each personal information is stored on a separate chain. Compared with the current leakage of personal information, the emergence of blockchain will effectively solve this problem. Question, secondly, there are many other applications of blockchain, private messages that need to be understood!

The current public misunderstanding about blockchain is mainly due to the state’s jurisdiction over digital currencies. The emergence of digital currencies has greatly threatened legal tender. The state has no control over this uncontrollable currency. Supported! However, if digital currency can be effectively popularized in the future, this decentralized currency will be even better than legal currency in terms of security and cost.

Based on the above personal opinions, if you are interested in blockchain and digital currency, please feel free to discuss in private!

Judging from the current situation, it is relatively simple for major Internet companies to test blockchain application functions and is still in its infancy. The real potential application space of blockchain (finance, government affairs, medical care, etc.) is still huge, and it will take time to slowly explore it. In the short term, it does not yet have the conditions for large-scale implementation. However, recently, major Internet companies have frequently deployed blockchain technology, which has played a positive role in cultivating and promoting blockchain in my country's market. Especially in the A-share market, it has attracted strong attention from investors. China Merchants Securities believes that through the conduct of major Internet companies, the audience of blockchain will gradually expand from niche players to the general public.

The current trend is good.

1. Distributed ledgers improve social efficiency.

2. Certain industries can reduce the need for intermediaries.

3. The development of storage and computing performance may bring more industry opportunities.

Bitcoin can solve these problems, and Bitcoin is BSV.

To be honest, the prospects are very good! If you want to talk about digital currencies like Bitcoin, I think the prospects are not great now. Firstly, because mining is now very difficult and it is basically difficult for individual users to mine it, but because the volatility is too high and the water level is too high. Deep down, investment is basically about losing more and making less. The money that can be made is miners and exchanges.

But blockchain is different. Blockchain is a technical and knowledge-based thing. It can be used in many aspects, such as shopping transactions, transportation and logistics, finance, insurance and many other aspects. It can be applied. Not many banks are now cooperating with Internet companies to develop blockchain.

Therefore, blockchain should have good application prospects in the future, mainly because the technology itself has many advantages and has a wide range of applications.

Blockchain definitely has development scenarios! Whether in finance or economicsBlockchain technology can be applied to many areas of , insurance, and shopping transactions. And due to the advantages of the blockchain itself, decentralization, asymmetric encryption, etc. are a good way to solve the current trust problems in people's production and life. The future prospects of digital currency may not be great, but I think blockchain has huge room for development.

Qianzhan believes that China’s blockchain market will maintain rapid growth, with a compound annual growth rate of 73% in market size from 2021 to 2026. The market size in 2026 will reach US$16.368 billion, and in the next 20 years , China’s blockchain industry market size is expected to reach the trillion level.

China’s blockchain industry market is developing rapidly

From 2017 to 2020, large IT Internet companies have deployed blockchain, start-ups have entered a blowout mode, and the industry scale has continued to expand. According to IDC According to the data, China's blockchain industry has experienced changes from a market size of US$85 million in 2017 to an industry scale of US$561 million in 2020.

In terms of the number of enterprises, in 2020H1, my country provided blockchain professional technical support, products, solutions and other services, and the number of new blockchain enterprises with input or output reached 303, a year-on-year increase of 274.07 %.

China’s blockchain patents account for a large proportion of the world, and the industrial aggregation effect is beginning to show.

From the perspective of the global competition landscape, my country’s competitive advantages in the blockchain industry are relatively obvious. Judging from the number of patents, according to data from the "Global Enterprise Blockchain Invention Patent Ranking in the First Half of 2020" released by IPRdaily, the world's authoritative third-party intellectual property agency, and the incoPat Innovation Index Research Center, the TOP 100 companies mainly come from 14 countries and regions. , China accounts for 46%, followed by the United States accounting for 25%.

As an important carrier for the development of blockchain industrial clusters, local governments are accelerating the construction of blockchain industrial parks. Judging from the location distribution of industrial parks, there are a large number of blockchain industrial parks in cities such as Beijing, Shanghai, Hangzhou, Guangzhou, Chongqing, Qingdao, and Changsha, forming a Bohai Rim agglomeration effect dominated by Beijing and Shandong, with Zhejiang and Shanghai , the agglomeration effect of the Yangtze River Delta dominated by Jiangsu, the agglomeration effect of the Pearl River Delta dominated by Guangdong, and the agglomeration effect of Hunan, Guizhou, and Chongqing dominated by Chongqing and Hunan. In the future, China's blockchain industry is expected to accelerate development relying on the aggregation effect.

Blockchain is the most widely used in the financial field

my country’s blockchain industry applications are mainly distributed in finance, supply chain, traceability and hardware, accounting for nearly 65%. According to the "Blockchain Blue Book: China Blockchain Development Report (2019)", there are nearly 28,000 blockchain companies in the country. Among them, about 1,000 blockchain companies have been put into production, accounting for only 3.6%. They are mainly concentrated in developed eastern regions such as Beijing, Shanghai, Guangdong, and Zhejiang.

The market capacity of the blockchain industry is expected to reach trillions in the future

Blockchain technology is a key direction for China’s new generation of independent innovation breakthroughs in information technology. It contains huge space for innovation, in chips, In fields such as big data and cloud computing, innovation activities are becoming increasingly active, and innovation elements continue to accumulate. The application of blockchain technology in various industries continues to deepen, which will give rise to a large number of new technologies, new products, new applications, and new models.

China focuses on accelerating the transformation of its economic development model, pays more attention to the improvement of economic quality and people's living standards, and uses new generation information technology, including blockchain technology, to transform and upgrade traditional industries and enhance the quality of traditional industries. Develop quality and efficiency, and improve the level of smart social management, public services and home life.

The huge market demand in the future will bring rare development opportunities and broad development space to blockchain technology. Researchers compiled and analyzed that China’s blockchain market will maintain rapid growth, with a compound annual growth rate of 73% in market size from 2021 to 2026. The market size in 2026 will reach US$16.368 billion, and in the next 20 years, China’s blockchain market will The industry market size is expected to reach the trillion level.

—— For more data, please refer to the "China Blockchain Industry Market Prospects and Investment Strategic Planning Analysis Report" by the Qianzhan Industry Research Institute

At present, the country also strongly supports the development of blockchain Technology is expected to be applied in various fields, so now some large companies, such as Tencent, Alibaba, NetEase, and the Internet are involved. It is still in the development stage, and we can look forward to the future

Blockchain Economy It cannot be simply understood as various virtual currencies. The essence of blockchain is to solve the problem of authenticity, confidentiality and non-tampering of information. (Everyone participating is a recorder of information, and everyone is only a part of the entire information chain. Ring) It more effectively solves the problems of privacy and integrity, so its application scenarios and prospects are broad and promising. (But it should not become a paradise for scammers)

Ⅲ The magical blockchain allows data to be retained permanently

At the beginning of this year, the Bitcoin fever wave had not completely passed, and another " "The torrent" could not stop the fire. This is the blockchain technology that has been hotly speculated in the financial and insurance fields recently, and has even made a strong presence in the stock trading and voting industries.

When talking about the recent hot spots in various industries, this technology must be one of them. Data to illustrate: So far, the world’s largest investment projects in 2016 are all related to blockchain, with investment amounts reaching US$55 million and US$60 million respectively. The largest blockchain project in China was also announced at the end of September this year. Also announced with an investment scale of over US$20 million.

First of all, normatively speaking, this is a new application model that comprehensively uses computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, and encryption algorithms. Bitcoin is well known as a globalCrypto Internet currency is developed based on blockchain technology, and the support of smart contracts on the blockchain makes a wider range of point-to-point transfers of digital assets other than Bitcoin a reality. It is not difficult to understand why the distinction between Blockchain technology will become compelling as the cornerstone of the Internet of Value.

So why is blockchain so attractive? If today’s Internet is the point-to-point transmission of information through the TCP/IP protocol, it is the information Internet, then the point-to-point transfer of value (such as electronic currency, electronic assets, etc.) without a third party is made possible by blockchain technology.

In layman’s terms, blockchain is a decentralized distributed accounting system. Nodes in the system do not need to trust each other. They jointly maintain a ledger through a unified consensus mechanism, and each node has a complete data record. Blockchain Blockchain, blocks of transactions are connected together through cryptographic algorithms, making the entire ledger open, transparent, traceable, and non-tamperable.

Compared with traditional third-party institution credit transactions, the process of blockchain in digital payment can be described as the following diagram:

IV Which industries will disappear due to blockchain technology?

Disappearance should be temporary, just like newspapers are still there after the emergence of Internet news. However, new technologies will definitely have a certain impact or even impact. Blockchain may have an impact on the following 12 industry areas:
1. Banking industry
As a digital, secure and anti-interference account, blockchain realizes the core functions of the banking industry : A safe storage and transfer center for value. In other words, in the next few years, a wave of companies based on blockchain technology may affect the banking industry. Indeed, Swiss company UBS and Britain’s Baeclays are both trying to use blockchain technology to improve payment terms. Some other companies in the banking industry even say that blockchain technology can eliminate $20 billion in intermediate fees.

Therefore, it is not surprising that banks, as financial services giants, have become a growth force in investing in blockchain startups. Capital One invests in corporate blockchain startup Chain (pictured above)
2. Payment and transfer
Recently, the World Economic Forum wrote an article in Forbes magazine that decentralized payment technologies—such as Bitcoin Coin—may change the “business structure” that has not changed in the money transfer industry for more than 100 years. Blockchain technology can avoid complicated systems and create a more direct payment process between payers and payees. Whether it is domestic transfers or cross-border transfers, this method is low-cost and fast, and does not require Intermediary handling fees. Abra (pictured above) is a company that uses blockchain technologyStartup making global Bitcoin and blockchain-based transfers.
3. Network Security
Although the blockchain system is public, its verification, sending and other data exchange processes use advanced encryption technology. This technology not only ensures the correct source of data, but also ensures that the data is not intercepted during the process. If blockchain technology is more widely used, the probability of being attacked by hackers may also decrease, so people think that blockchain systems are more stable than traditional systems. One of the reasons why blockchain systems can reduce traditional network security risks is that they eliminate the need for middlemen.
“Eliminating the middleman not only reduces the potential security risks of hacker attacks, but also reduces the possibility of corruption,” Goldman Sachs writes. Guardtime (pictured above) is an Estonian startup that specializes in industrial-grade network security solutions based on blockchain technology.
4. Academic records and academia
Holbertson School, a California software skills project, announced that it will use blockchain technology to authenticate academic certificates. This move will ensure the authenticity of course identification for Holbertson School students. If more schools adopt this kind of transparent academic certificates, transcripts and diplomas, corruption in academia will be greatly reduced, not to mention the saved manual verification time and paper document costs.
5. Elections
At West Virginia University, the student union is considering whether to use a voting platform based on blockchain technology to conduct school elections. Using such a platform, students would be able to vote using their mobile devices, and since the results would be counted in a public system, voting would be completely secure. One student who supports this approach explained that your votes “can never be modified or deleted by us, the programmers, school administrators or students.”
A Spanish software project, used by Agora Voting Using encryption technology to improve the security of online voting, several of their systems are also being trialled in Spain. Recently, leaders of this project have proposed several ideas for converting Bitcoin and blockchain technology into voting applications, although these ideas are far from experimental.
6. Car rental and sales
Late last year, Visa and DocuSign announced a cooperation plan to use blockchain technology to create a specific solution for car rental. In the future, car rental only needs to "click and sign" , open" can be completed in three steps. The specific operation is: the customer selects the car he wants to rent, and then the transaction will be uploaded to the public account of the blockchain; then, the customer signs a rental agreement and insurance agreement from the driver's seat, and the blockchain will transfer the information in real time. Upload. It is not difficult to imagine that this leasing model may also be used in the field of car sales and car registration.
7. Network communications and the Internet of Things
IBM and Samsung are working together to implement aThe conception of ADEPT. ADEPT uses blockchain technology to create the backbone of the decentralized Internet of Things. CoinDesk said that with ADEPT, a decentralized p2p automatic telemetry system, the blockchain can become a public system for many devices, and there is no need for a central hub to mediate the communication of various devices. After the central control system recognizes each other, devices can automatically communicate with each other and manage software updates, bugs, or energy consumption.
A number of other companies are also working on integrating blockchain technology into IoT platforms. For example, Filament, which uses blockchain technology to build a decentralized network for sensors to communicate with each other, announced that they have received US$5 million in Series A financing, with participation from Verizon Ventures and Samsung Ventures.
8. Smart Contracts
A smart contract is actually a computer program that functions on the actions of another object. Like ordinary computer programs, smart contracts are also an "if-then" function, but blockchain technology enables the automatic filling of these "contracts" without manual intervention. Such contracts may eventually replace the legal industry's core business of drafting and managing contracts in both commercial and civil areas.
For example, mortgage loans can be completed through blockchain technology and automatically executed every year according to the terms of the contract. Ethereum, a crowdfunding platform built using blockchain technology, not only provides decentralized applications but also smart contracts, and users have already gotten married using their smart contracts. Another company, Hedgy, received $1.2 million in seed round investment from Tim Draper, Marc Benioff, Boost.vc and Sand Hill Angels earlier this year. This company uses smart contracts to create a platform that supports users to negotiate the value of Bitcoin. .
9. Prediction
Blockchain technology may shake up the entire research, analysis, consulting and forecasting industry. Online crowdfunding platform Augur hopes to make profits on a decentralized prediction platform. The company says it will offer a service that looks like a betting swap. The entire process will be decentralized, and the Augur platform will not only provide users with sports and stock betting services, but also election and natural disaster betting services. The idea actually goes beyond sports betting and creates a “prediction market.”
10. Online Music
Many musicians are choosing blockchain technology to improve the fairness of online music sharing. Billboard reports that two companies are currently automating licensing issues by paying artists directly and leveraging smart contracts. PeerTracks, which is still in its development stage, wants to create a new music streaming platform where users can pay artists directly without the involvement of middlemen. PeerTracks also hopes to create a connection between artists and usersCreate more direct interactions.
Ujo Music, led by entrepreneur Phil Barry, claims that they are rebuilding the music industry on the blockchain. Ujo also hopes to solve the problem of streaming music and paying artists. In addition to streaming music, it is also envisioned that by using smart contracts as an autonomous brain for song listings, Ujo will be able to better classify the artists and creators behind the songs.
11. Trip Sharing
Travel applications such as Uber seem to be on the opposite side of decentralization. The company is like a dispatch center, using its algorithms to control its drivers and driver charges. According to Bloomberg, Israeli startup La'Zooz wants to "do the opposite of Uber." The company has invented its own patented digital currency that, like Bitcoin, can be digitally recorded using blockchain technology. Unlike using a centralized network to hail a ride, users can find people with similar itineraries on La'Zooz and then pay for the ride in La'zooz currency. The coins can be used when requesting a ride in the future, and users can earn La'Zooz's digital currency simply by allowing the app to track their location.
12. Stock Trading
For many years, companies have been looking for ways to simplify the process of buying, selling and trading stocks, and emerging blockchain technology startups believe they can go beyond the past and automate the entire process. Improve safety and efficiency. TØ.com, a subsidiary of Overstock, wants to use blockchain technology to enable online trading of stocks. Wired reports that Overstock is already using blockchain technology to issue public shares. At the same time, blockchain technology startup Chain (mentioned above) is joining forces with Nasdaq to implement share transactions in private companies through blockchain technology.

IV Is blockchain useful? What is the impact and prospects of blockchain?

I believe everyone is no longer unfamiliar with the emerging technology of blockchain, because this is the current The most popular topic of Jiao Chun, many big guys in different industries are analyzing its role and prospects. Today we also do some research on the blockchain. Is the blockchain useful and what is the impact of the blockchain? and prospect analysis, I hope it can help everyone.
Is blockchain useful?
1. Banking: As a digital, secure and interference-proof account, blockchain realizes the core function of the banking industry: a safe storage and transfer center of value. In other words, in the next few years, a wave of companies based on blockchain technology may affect the banking industry.
2. Payment and transfer: Blockchain technology can avoid complicated systems and create a more direct payment process between the payer and the payee. Whether it is a domestic transfer or a cross-border transfer, this method has its advantages. Low price, fast, and no intermediate handling fees.
3. Network security: Although blockchainThe system is public, but its verification, sending and other data exchange processes use advanced encryption technology. This technology not only ensures the correct source of data, but also ensures that the data is not intercepted during the process. If blockchain technology is more widely used, the probability of being attacked by hackers may also decrease, so people think that blockchain systems are more stable than traditional systems. One of the reasons why blockchain systems can reduce traditional network security risks is that they eliminate the need for middlemen.
4. Election: Everyone's vote "can never be modified or deleted by us - programmers, school administrators or students."
5. Smart contract: Smart contracts are actually on another object. A computer program that functions on the go. Like ordinary computer programs, smart contracts are also an "if-then" function, but blockchain technology enables the automatic filling of these "contracts" without manual intervention. Such contracts may eventually replace the legal merger industry's core business of drafting and managing contracts in both commercial and civil areas.
6. Stock trading: For many years, companies have been trying to simplify the process of buying, selling and trading stocks. Emerging blockchain technology startups believe they can go beyond the past, automating the entire process, improving security and efficiency.
What impact and prospects does blockchain have?
1. The dual impact of bringing wealth and risk:
The difference between blockchain technology and traditional Internet technology is that it chooses the high-risk financial industry as the entry point, but the financial field is full of Areas with many obstacles. Such direct entry has a dual impact: on the one hand, it can bring wealth effects to entrepreneurs relatively quickly; on the other hand, various risks will also come directly and violently.
2. Improve efficiency and reduce costs:
For physical finance, blockchain can maintain the fidelity in the process of transmitting information, such as personal credit information and other data, thereby avoiding many transaction costs and enabling large-scale Improve efficiency, this is the positive meaning it brings.
3. Control financial risks early and small:
Blockchain is cooperating with the innovation of digital currency, preventing over-insurance in the insurance industry, over-lending in bank mutual funds loans, and the integration of supply chain finance. , promote electronic identity recognition, etc., applicable to many industries and fields. In terms of financial security, many companies have also cooperated with regulatory authorities to build regulatory technology systems to help regulatory authorities monitor and provide early warning for the risks of Internet financial companies, so as to control financial risks early and at an early stage.
4. The owner of the data should be the user himself:
Blockchain is a technology worthy of attention, and it has relevant layouts in its own business and investment. Bitcoin and other electronic currencies are applications based on blockchain technology. They have certain currency functions and have certain use value. However, the main problem now is that the gap between the use value and the transaction price is too big. . ICO is a financing business model.
5. The darkest stage contains the most opportunities:
The darkest stageIt often contains the most opportunities. The application scope of blockchain is far beyond currency and finance. For example, big data can be applied to the entire medical and health field in the future. If medical records and diagnosis data are shared to all different medical systems through the big data blockchain, the efficiency of treating diseases and saving lives can be greatly improved.
The editor believes that the correct development prospect of blockchain is to "talk less about financial innovation, focus more on financial security, focus more on inclusive finance, and do more on medical care, health, and environmental protection."
The above is the blockchain brought to you by the editor. Is it useful? What impact and prospects does blockchain have? all content.

VI What is "Blockchain"

Blockchain is a public ledger. There is no centralized hardware or management organization and anyone can Automatically verify the authenticity of the ledger and easily detect whether the ledger has been tampered with by others.

In a word, the blockchain is a public ledger that can be verified by everyone.

The concept of being verifiable by everyone is crucial to blockchain.

Bitcoin uses the blockchain to record all transactions, so anyone knows the number of Bitcoins on each account.

So, as a publicly verifiable ledger, what are some use cases for blockchain?

In fact, there are many use cases that can be thought of. Blockchain is suitable for any data that can be recorded on a public ledger. Here are 4 examples:

1. Decentralized domain name server, namely domain currency. The domain name server is actually a ledger that records domain names.

2. Trustless public key encryption, such as https that discards unreliable certification authorities.

3. Ownership records, truthfully record the items and their corresponding owners.

4. Contracts and performance guarantees, the account book truthfully records the parties to the contract and saves the contract text.

But don’t forget that blockchain also has a very important component.

The ledger recorded using blockchain technology will always be updated. New data such as transactions, domain name inputs, records and contracts will be converted into hash values ​​of the same length by the hash algorithm and saved. However, hashing algorithms are not only not free but also very expensive.

Therefore, the ledger itself needs to have a recognition system to recognize the person who enters the block hash value.

In Bitcoin, this system is called mining and is rooted in the Bitcoin protocol. Bitcoin miners use a hash algorithm to convert transactions waiting for verification into hash values, and charge a certain amount of Bitcoin as a service fee.

Therefore, for non-monetary use cases, blockchain needs to find a way to bear the high cost of hashing algorithms.

I would like to remind everyone that my answer mainly focuses on the possible applications of blockchain technology.Which use cases do not cover all aspects of blockchain, such as why hashing algorithms are so expensive. I'm sure you can find a lot of detailed information about Bitcoin and other blockchain applications online.

Supplement

Although blockchain technology has many advantages, there are still some less than ideal use cases. For example, there is no way to convert Bitcoin into any national currency; a ledger with billions of data entries would take up space and be impractical.

Bitcoin has shown the world that blockchain technology is feasible in principle, and people are also trying to solve these increasingly prominent problems, such as technological transformation of Bitcoin or the introduction of a completely Different blockchain technologies. I think the following two methods are worth trying: one is to split the ledger according to certain standards such as the payer address, and the other is to introduce a main blockchain to verify the sub-blockchain. Blockchain technology is ever-changing and dazzling, and it’s unknown whether someone is already making such an attempt. But Bitcoin is still the world's first currency blockchain, what others call a cryptocurrency.

Whether in the technology circle or the financial circle, blockchain has become the hottest word, no one. Blockchain has core advantages such as decentralization and trustlessness, and can perfectly solve problems such as information asymmetry, high transaction costs, and trust of strangers in the development of the sharing economy, making "individual economy" possible. Based on this, blockchain technology is considered to be the core technology that has the greatest potential to trigger the fifth wave of disruptive revolution after steam engines, electricity, information and Internet technology.

In this context, a blockchain craze was born in society, and everyone praised it overwhelmingly. Dialectics tells us that everything has flaws, and only by seeing the pros and cons of things can we make rational decisions. Therefore, in this article, Xue Hongyan (Hong Yanweiyu), a senior researcher at Suning Financial Research Institute, focuses on pouring some cold water on the blockchain.

| What is Blockchain

Blockchain, English Blockchain, has a rather mysterious technological flavor in its name, and can be simply broken down into "data blocks" and "links". Each data block contains all the information exchange data of the system within a certain period of time, and is encrypted using cryptographic methods; the link means that each block has a link relationship with the next block, thus forming a blockchain.

It is generally believed that blockchain has two major characteristics: decentralization and trustlessness. A brief introduction is as follows:

Since each block contains all the information exchange data of the system within a specific period of time, Therefore, each block is equal, and the damage of a single block does not affect the security of the entire system, so the blockchain has decentralized characteristics.

Similarly, since each block contains all the information of the system, the authenticity of the information isBased on cross-validation, only more than 51% of the nodes can be tampered with. In a large enough blockchain system, the cost is extremely high. It can be considered that the information in the blockchain is true, so the blockchain has the ability to Trust characteristics.

Most people’s understanding of blockchain begins with Bitcoin. The relationship between the two is that blockchain is the underlying technology and concept, and Bitcoin is only the most popular application of blockchain at present. .

Maybe the above is not popular enough. Finally, let me summarize, what do you think the blockchain is? Is it a disruptive new technology? NO! According to Xue Hongyan (Hong Yanweiyu), a senior researcher at Suning Financial Research Institute, blockchain is not so much a new technology as it is a new ideological concept. The information encryption and other technologies included in the blockchain have been around for a long time, and it is more of a conceptual innovation. This is also the reason why the blockchain has a huge impact. New technologies will be surpassed sooner or later, ranging from one or two years to four to five years; only innovative ideas have enough energy to affect all aspects of the economy and society.

| Blockchain is expected to change the underlying rules of the financial system

In applications in the financial field, blockchain will change the transaction process and record keeping methods, thus significantly reducing transaction costs. It has significantly improved efficiency and is considered to have a broad market environment in digital currency, cross-border payment and clearing, bill trading, securities issuance and trading, property rights transactions, customer credit reporting, anti-fraud, and anti-money laundering.

Such a good technology is naturally sought after by everyone. Like many traditional financial people, Hong Yanweiyu resisted it at first, thinking that this thing was not that great, and did not do any research specifically. Later, as the research on financial technology gradually deepened, it was discovered that blockchain was an obstacle that could not be bypassed, because whether it was robo-advisory, big data risk control or online lending, they were only technological innovations at the financial business level and risk control level. It has not penetrated the bottom layer of the financial system. What is the underlying layer of the financial system? Naturally, it is payment and settlement, transaction rules and system interaction. What the blockchain changes is precisely the underlying rules.

Therefore, throughout the world, financial institutions are the most active in researching blockchain. If nothing else, they are really afraid. After the decentralization and trustless features of the blockchain are fully utilized, what else will the intermediaries of financial institutions do? It is estimated that this is also the first feeling of many people who have a preliminary understanding of blockchain.

In this article, Hong Yanweiyu focuses on pouring cold water on this view.

| Subverting the financial system, blockchain still faces two mountains

Marxist dialectics tells us that everything has two sides. The more prominent the advantages, the more obvious the flaws. It’s just the perspective. Just different. The two major problems with blockchain subverting the financial system lie precisely in the two major advantages of decentralization and trustlessness.

First, let’s talk about decentralization. First, we must make it clear that centralization must meanInefficient? Of course not. Within a specific scope, the concentration of resources brought about by centralization can greatly improve efficiency. This is also the reason why human beings evolve from individuals to villages to tribes and then to countries in the process of evolution. Take UnionPay as an example. UnionPay is the clearing and settlement center for the domestic banking industry. After UnionPay is established, each bank only needs to connect with UnionPay to realize transactions with all banks. If it is decentralized, without UnionPay, each bank will need to When communicating with all counterparties, which one is more efficient? Therefore, there is no need to beat centralization to death with a stick. The decentralization feature of blockchain is destined to only play a role in specific fields (that is, fields that are not suitable for centralization). How can it subvert everything?

Furthermore, it is a matter of trust. There is nothing wrong with detrusting itself, but the technical logic behind it is deeply flawed. Blockchain relies on universal accounting to achieve trustlessness, that is, all transaction information is retained in each block for system cross-verification to identify authenticity. Here comes the problem. Each block retains all transaction information. There is no problem on a small blockchain. However, as more and more information is added, it will inevitably lead to an explosive growth of transaction information and will also bring information. Dramatic increase in storage costs. At the same time, the greater the amount of information, the longer cross-validation takes and the lower the efficiency. Therefore, the blockchain solves the trust problem, but it brings about rising costs and declining efficiency.

Nothing in the world is perfect, and the same is true for blockchain.

As a conclusion, Hongyanweiyu wants to clarify that blockchain, as a conceptual innovation, does have great value and can also have a disruptive impact in specific fields. However, the current one-sided thinking about blockchain is problematic. Eastern wisdom tells us that "the most brilliant and the golden mean", in the face of anything, it is wisest to maintain the golden mean.

(Text/Xue Hongyan, senior researcher at Suning Financial Research Institute; WeChat public account: Hongyan Weiyu)

As early as a few years ago, the word "mining" came with Bitcoin is well known for its popularity. Many people know about Bitcoin first and then the blockchain, and they even don’t know about the blockchain yet. By definition, blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction, which is used to verify the validity (anti-counterfeiting) and generation of its information. Next block.

I am not a computer technology expert. The following introduction to blockchain comes from reading and comments from expert friends and is for reference only.

If you want to use one word to explain blockchain, it is: distributed accounting.

To understand what this word means, you need to first understand that traditional accounting has a center. For example, in a bank, when you withdraw money from a bank deposit or lend money to others through the bank, the bank is the center. All these transactions are based on the bank's credit. What if the bank cheats? Or worse, the country is playing tricksWhere is Lai? The Kuomintang's indiscriminate issuance of gold yuan coupons at the end of its rule in mainland China, as well as the hyperinflation in Weimar Germany and Zimbabwe, which made the currency less valuable than toilet paper, are very famous examples.

Golden Yuan Coupons

This is the problem that blockchain is aimed at. They believe that decentralized accounting is non-modifiable and non-repudiable. How to achieve decentralized accounting? The basic idea is that all users store all transaction records, and through mathematical methods, it becomes very difficult to illegally modify the ledger. In this way, the reliability of the ledger is guaranteed.

Specifically, all users exhaustively enumerate random number variables, and the first user to obtain a specific required hash function value (Hash) will have the right to record this round of transactions and obtain the corresponding Bitcoins award. It is transmitted in the form of data blocks, and the data blocks are connected into a chain by appending at the end, so it is called a block chain.

After listening to the introduction, you may feel that this idea is interesting, but it is not as exciting or revolutionary as advertised. Your feeling is right. In fact, the basic logic of blockchain has some unavoidable problems.

For example, the current size of the complete Bitcoin public ledger has exceeded 150 G, and is rapidly increasing at a rate of tens of G per year - just to support 5 million users and 30 million transactions per year. If its processing volume is one day comparable to that of Alipay, the size of the Bitcoin ledger will increase by more than 500 terabytes per year. This is equivalent to backing up the Alipay server's storage data on all users' personal computers. Do you think this is a good idea?

For another example, in the traditional banking system, if you lose your password, it is no big deal. Just report it to the system in time, and your wealth will not disappear. But in the blockchain system, if you lose your password, it will be a huge trouble, and your currency will not be recovered. Not happy? Is it surprising?

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system

In layman’s terms, it is playing mahjong. Four people can take turns to be the banker, and each other can shoot four people. They all have their own ledger records, but if you want to modify the ledger, you must have more than 50% of the modification rights, so the cost of cheating on the ledger is very high.

In the future, blockchain will be used more in finance to combat money laundering and fraud, because all information can be traced, and in culture it can be used for copyright protection, etc.

< /p>

I have seen a lot of people’s explanations of blockchain using official rhetoric, and some may not even be explained by the people themselves.Not sure. I will explain the blockchain in vernacular below to ensure that everyone can understand it.

What is blockchain? Let me give an analogy. In 50 years, you can buy an electric fan from the supermarket. This electric fan will automatically help you mine coins while using the electric fan. When you use the electric fan, you can automatically mine coins. When the fan breaks down, you can use the mined coins to repair the electric fan. Of course, you can also use the mined coins to buy a new electric fan. Many people think wrongly! Wouldn’t the profits of merchants be less? Let me tell you about a certain brand. When the products of this brand are sold to you, the products themselves may even be sold to you at a loss. However, once the number of users becomes large and the users become more sticky, they can be paid through membership fees or service fees. Such small fees or other ways to make profits. Just like this, the mined coins can be purchased and repaired. Although the merchant's profit may be reduced, the merchant has gained more users and greater user stickiness. By this time, it only takes a minute for the merchant to make money.

And the electric fan you bought is equivalent to winding it up for you. What is winding up? If you put your electric fan on the street now, and 10 people come to snatch it, you have no way to prove that the ownership of this electric fan is yours. Once you put it on the chain, it is equivalent to being tied to you. Once it’s settled, you can prove it.

Therefore, the essence of blockchain is to help make people’s lives more convenient. It is equivalent to upgrading on the basis of the Internet, making it safer and more convenient. This is blockchain! It's that simple.

The security of the blockchain is reflected in its irreversibility and the data cannot be tampered with. We all know that in today's society, any data can be modified and conquered by hackers, but the data in the blockchain cannot be changed. Once generated, it cannot be modified unless all users in the blockchain work together. Agree to modify the data, but this is unlikely to happen.

At present, the blockchain is still very immature, just like the Internet bubble burst in 2000. When the bubble bursts, a truly valuable blockchain Internet will be hatched. company.

The wheel of history will not go backwards. Many people are unwilling to accept blockchain. Just like telling you that you can shop online 20 years ago, this is the same ridiculous thing. Time will eventually prove it. .

1. The main function of blockchain is to store information. Any information that needs to be saved can be written to the blockchain and read from it, so it is a database.

2. Anyone can set up a server, join the blockchain network and become a node. In the world of blockchain, there is no central node. Every node is equal and stores the entire database.. You can write/read data to any node, because all nodes will eventually be synchronized to ensure that the blockchain is consistent.

3. Everyone works on the same blockchain, everyone publicly shares the current state of the blockchain, everyone agrees on the rules for new data submission and tampering with the blockchain is prohibited. It is difficult to operate in terms of computing power.

If we assume that the database is a ledger, reading and writing the database is an accounting behavior:

Anyone can verify this public ledger, but there is no single The user can control it. Participants in the blockchain system will jointly maintain the update of the ledger: it can only be modified according to strict rules and consensus, and there is a very exquisite design behind this.

(1) Accounting, the system will find the person with the fastest and best accounting within a period of time, let this person do the accounting, and then broadcast the information on this page of the account book to everyone else on the entire network. node, which is equivalent to changing the database record; (consensus mechanism, cryptography)

(2) Verification, other valid nodes in the entire network check the correctness of the block accounting, and stamp the time Stamp to confirm that the block is legal; (timestamp, mathematics)

(3) Form a single chain, that is, compete for the next block after the previous legal block; (smart contract, encryption technology)

p>

(4) Storage, the account book is stored in blocks. As transactions increase, new data blocks will be appended to the existing chain to form a chain structure; (distributed structure, information technology) < /p>

(5) Backup, every participating trader is a node of the block network, and each node has a complete backup of the public account book, which is a distributed ledger.

Features

1. The blockchain has no administrator and is completely centerless. It is precisely because it cannot be managed that the blockchain cannot be controlled. Without an administrator, everyone can write data into it. In order to ensure the trustworthiness of the data: the technology of blockchain makes it impossible to tamper with the data once it is written.

2. Close to zero trust cost.

The cycle time required for Internet companies to build their credit is extremely long. For example, Taobao often takes several years to build its credit. In the blockchain, everyone trusts the code, algorithm and rules, so the cost of trust is extremely low.

3. The marginal cost of constructing and trading assets approaches zero.

If traditional assets are to be used for trading, they need to rely heavily on third parties, such as investment banks, banks, securities firms, etc., for packaging and endorsement, and the fees and thresholds are extremely high. With blockchain, these will not be a problem, and the cost is extremely low.

The value transfer attribute of the blockchain also naturally solves the payment problem, and has the genes to support global payments.

According to my current understanding

1. Blockchain is an outlet.

Everyone is talking about blockchain. Whether they have read it or not, whether they understand it or not, many people are forwarding blockchain articles in their circle of friends. The only new WeChat group is Blockchain related groups.

Investors are talking, entrepreneurs are talking, almost every major Internet company is talking about it, government departments are taking a stand, and tens of thousands of vertical media focusing on blockchain are quickly born.

If you don’t join any currency circle or chain circle, you will be completely out. Even the well-known investment tycoon Zhu Xiaohu was unilaterally declared to belong to the old world by the rising star Chen Weixing.

2. Blockchain represents the story of sudden wealth.

Although ICO has been stopped by the national level, the most popular word-of-mouth about blockchain is still the increase in wealth by hundreds or thousands of times. Coins that were bought for a few cents or a few dollars are now worth dozens or hundreds of dollars. Everyone is talking about value-added stories.

There are Bitcoin and Ethereum. If you download a digital currency trading platform APP, the various currency codes composed of densely packed letters will feel like a stock exchange.

3. Blockchain is not only a technology, but also a belief at the conceptual level.

The basic layer, application layer, and a lot of blockchain knowledge seem to have a lot to do with the hot artificial intelligence.

Many people say that blockchain technology is mature, but applications have barely found an entrance. We can all shout loudly: Artificial Intelligence +, but if you shout "Blockchain +" now, it's not enough and you will be laughed at. The application scenarios are still being explored.

As for the previous Internet, it was an Internet of confidence. With the addition of blockchain, it became an Internet of value.

Such similar concepts are people’s good expectations for blockchain technology to solve the trust problem. If it is so easy to implement, blockchain can subvert finance, e-commerce, and many intermediaries. But why has the Internet not been subverted for so many years and real estate still relies on intermediaries?

4. Blockchain already has a history, so don’t think it is too new.

Just as many people claim that artificial intelligence is so new that it is a joke, its history can be traced back to the 1950s.

The blockchain is marked by the birth of Bitcoin, which was 10 years ago. There is also a still mysterious founder, Satoshi Nakamoto, who seems to have a Japanese name, and some say he is from the United States. From the Security Bureau, I think it can also be interpreted as "Chinese people are inherently smart", of course the latter is just a joke.

The reason why it has become so popular is because of the skyrocketing price of various digital currencies in 2017, which skyrocketed thousands of times in a few months and days. How could there be such an amazing speed in the past?

5. Blockchain is a knowledge system.

For me, it is the windWhether it is words, whether it is wealth, games, or technology, we cannot ignore it or ignore it.

I started to make two columns to understand the blockchain from the perspective of characters, stories and characters. One is "Blockchain 100 People (Industry People)" and the other is "Blockchain 100 Investors". (Viewpoint)” Learn and spread at the same time.

As for related books, of course, I will accept them all as ordered. I can only be a follower of various trends and follow suit.

The biggest mistake is not how we criticize the blockchain, but to ignore it when we see it has a huge bubble and the crowd is enthusiastic about it. Stay away from it if you think you are noble.

The only way we have left is to be willing to be students, learn, and learn again.

Literal meaning: block, chain, using a chain to connect each block.

Blockchain = distributed data storage + point-to-point transmission + consensus mechanism + encryption algorithm

What is data storage? For example, a supermarket must have a ledger to record the entry and exit of various goods and transactions. This is storage.

What is distributed storage? It is the account book of this supermarket. Every employee has a copy. Every time there is something that needs to be recorded, it will be recorded in everyone's account book in a timely manner. Distributing each ledger (storage) to countless people (places) is distributed storage. (The supermarket employees here can be understood as blocks, and the ledger is the chain)

What is point-to-point transmission? In the same supermarket, there is no yogurt at the front desk. The shopping guide reports it to his superiors, and then reports it to his superiors.... Finally, he reports it to the warehouse. The warehouse records the accounting records in the ledger, and then transfers the goods to the front desk. As for point-to-point transmission, if there is no yogurt at the front desk, the shopping guide directly tells the warehouse, and the quantity sent by the warehouse to the shopping guide is recorded in the ledger. Everyone knows how many goods the warehouse has sent to the front desk. This is point-to-point transmission. There is no intermediate link, but the accounts can be made public for everyone who holds the ledger to see.

What is consensus mechanism? The consensus mechanism mainly includes two points. In a simple summary, the minority obeys the majority and everyone is equal. Similarly, the positions in this supermarket may be high or low, but everyone’s account books are indeed the same and equal. If someone makes a false account, then this person's account must be different from other people's accounts. At this time, it depends on whose account is remembered by more people. In theory, as long as the blockchain is large enough, then there is no need to make false accounts. Limit reduction! Because of the "minority obeys the majority" mechanism, if you want to make false accounts, then the number of false accounts you need to make must be at least greater than 50% of the total! On a network, if you need to change a piece of data, you must control at least 50% of the total number of computers to succeed.

Encryption algorithm This is easy to understand. That is, when you go to the warehouse to transfer goods, the system will protect your privacy very well. It will only record the time and location.A certain number of people went to mix the yogurt, not the time, place, and Zhang San went to mix the yogurt. Taken together, this is the core component of the blockchain.

Personally, I think its main function is to decentralize and protect data from being tampered with! Decentralization and data protection are actually related. A supermarket only has one ledger, and any scheduling needs to go through the person who manages the ledger. If you need to make false accounts, you only need to control the person who manages the ledger. And if that supermarket uses blockchain technology, then he will make false accounts. If this is the case, you need to control more than 50% of the people who hold the total number of accounts of that supermarket. Obviously, controlling so many people will be almost impossible as the number of holders increases.

Ⅶ Blockchain technology will change these 18 major industries in the future

Blockchain technology will change these 18 major industries in the future
Since the birth of the Internet, the cost of information dissemination has been extremely high The efficiency of information dissemination has been greatly improved, and social productivity has been liberated as never before. It is no exaggeration to say that the Internet has changed the entire pattern of human society.
However, while enjoying the many conveniences brought by the Internet, we have to admit that the Internet still has many flaws, especially in terms of security and mutual trust. The birth of blockchain technology has brought a new dawn to solve the problems existing in the Internet society.
Because blockchain technology is open and transparent, difficult to tamper with, and does not rely on intermediaries, blockchain can achieve safe, efficient, and low-cost value transmission. People are expected to build an Internet for value transmission based on blockchain to further promote the liberation of social productivity.
At the same time, just as "every new technology appears will change or even subvert many industries," in the future blockchain will change these 18 major industries!

1. Banking Industry
The application of blockchain technology in the financial field will change the transaction process and record keeping methods, significantly reduce transaction costs, and significantly improve efficiency.
2. Cybersecurity
Although blockchain is not a panacea to fix all Internet problems, it can be a powerful tool for experts and engineers, especially systems with single points of failure and centralized vulnerabilities.
3. Supply chain management
The supply chain is a complex functional network chain structure composed of suppliers, manufacturers, distributors, retailers, and users. In this chain, capital flow, information flow, and physical flow operate interactively, making coordination extremely difficult. The traditional coordination mechanism that relies on a single "chain owner" has encountered bottlenecks. The "decentralized" model of blockchain provides rich imagination for solving this problem.
4. Prediction field
The prediction market needs a platform that is decentralized, open and transparent, and more adaptable to global user participation to change the status quo, and this naturally matches the characteristics of the blockchain. Whether from sports betting to stocks to elections, these technologies allow for decentralized betting and observation.
5. Network and Internet of Things
The blockThe idea of ​​applying blockchain technology to the Internet of Things (IoT) has been around for some time. In fact, blockchain technology looks to be a suitable solution for at least three aspects of IoT: big data management, security and transparency, and micro-transactions based on the exchange of services between interconnected smart devices. Comes in convenience.
6. Insurance industry
The power of technology is making the insurance industry return to its essence: linking objects, regaining trust, and sharing. In other words, the law of large numbers in the traditional insurance industry may encounter more uncertainties and create new possibilities due to technology, technology, and links.
7. Sharing Economy
Blockchain is inherently decentralized, which is highly consistent with the purpose of the sharing economy. The "Tencent Blockchain Solution White Paper" shows that Tencent is applying smart contracts to bicycle rental, house sharing and other fields. If this smart contract is applied to today's popular bicycle sharing field, it may bring new changes to the entire industry.
8. Cloud Storage
Blockchain technology can support distributed storage of encrypted data and is the core of collaborative cloud storage.
9. Charity industry
For charity, the openness and transparency brought by blockchain technology can ensure that donors can clearly understand the flow of their funds and can query it; the non-tampering feature can also ensure that financial Information cannot be tampered with; anonymity also protects donor privacy.
10. Voting
Blockchain technology can be applied to voter registration, identity confirmation, and electronic statistics to ensure that only legitimate votes are recorded and that votes will not be tampered with or removed. Create an immutable, publicly visible ledger of voting records to make elections fairer and more democratic.
11. Government Management
Government services are one of the most direct and significant application areas of blockchain technology. Information exchange across agencies will effectively improve government efficiency.
12. Public welfare industry
Internet culture itself has the genes of equality, openness, and mutual assistance, which is very consistent with the characteristics of public welfare.
13. Medical industry
The medical industry currently still relies on old systems and lacks ways to store data securely. Blockchain can be widely used in medical and health information sharing, medical process transparency, and medical accident liability traceability.
14. Energy Management
In order for the Energy Internet to be successfully implemented, various information interactions, smart grid control and scheduling, and coordinated control of distributed power sources are all obstacles that must be overcome, and blockchain Technology is trying to solve these problems.
15. Music Copyright
The importance of music copyright is self-evident to online music platforms. Having more copyrights means that it can capture more users, and the platform can therefore obtain better Development opportunities.
16. Retail industry
When we shop, we need to trust the store’s retail system. DecentralizationThe blockchain can make retail different, where buyers and sellers can connect directly without middlemen and fees.
17. Real Estate Industry
Blockchain technology can change the way the real estate market operates. It can merge many complex processes and cases that real estate companies usually deal with, speed up transaction processes, reduce fraud, and provide benefits for everyone. Participants provide more transparent and secure transactions.
18. Your industry
If your industry deals with data or any trading system, it is very likely to be changed by blockchain. This is an open field full of opportunities.
Of course, as an emerging technology, the application of blockchain still faces many challenges. More blockchain technology companies like Matrix are needed to overcome the difficulties in practical application of blockchain and promote blockchain technology. The widespread application and development of chains.

Ⅷ Understand the Internet blockchain in one article

Understand the Internet blockchain in one article

Understand the Internet blockchain in one article. To understand the blockchain, We have to study the brief history of blockchain technology development starting from the birth of the Internet, discover the motivations for blockchain, and infer the future of blockchain. Let’s understand the Internet blockchain in one article.

Understand the Internet blockchain in one article 1

The originator of blockchain is mahjong, and the earliest blockchain was invented by the Chinese! The blockchain is just like Mahjong, except that Mahjong has fewer blocks. Mahjong only has 136 blocks. The rules of Mahjong vary from place to place and can be regarded as a hard fork of Bitcoin.

As the oldest blockchain project, Mahjong has a team of four miners. The first one to dig out the 13 correct hash values ​​will get the accounting rights and rewards. It adopts the method of being willing to admit defeat and not cheating. Thousands of consensus mechanisms!

Mahjong is decentralized, everyone can be the banker, and it is completely peer-to-peer.

Mining pool = commission from the boss of the chess and card room.

It cannot be tampered with, because convincing the other three people requires too much computing power and physical strength.

A typical value Internet. The value in my pocket didn't last eight rounds before it went into their pockets.

The Chinese are basically good at playing mahjong. In terms of blockchain, they produce 70% to 80% of the world’s mining machines and have the most computing power in the world, accounting for about 77% of the computing power.

Mahjong is actually the earliest blockchain project:

1. A group of four miners. The miner who first collides with the correct hash value of 13 numbers can obtain the accounting rights. and get rewarded.

2. It cannot be tampered with. Because convincing the other three people requires too much computing power and physical strength.

3. Typical value Internet. The valuable digital currency www.gendan5.com/digitalcurrency/btc.html in my pocket ran into their pockets in less than eight rounds.

4. Decentralization, everyone can be a banker, it is completely peer-to-peer.

5. UTXO, unspent transaction expenses.

There is another blockchain method of credit, assuming that everyone has no cash

Let’s take a closer look. When everyone reaches a consensus, we see There is no intermediary or third party to judge C’s win, and the rewards given to C do not need to be transferred to C through a third party. They are all direct peer-to-peer transactions. This process is decentralized, and players (miners) record their own records. After recording the results of the first game, B Dahu drew thirteen pieces, and B drew Jia Dongfeng. After the record is completed, a complete block is generated, but remember, this is only the first game. In the entire blockchain , this is just one node. After the 8 rounds mentioned at the beginning, there are 8 nodes (blocks). The 8 blocks are connected together to form a complete ledger, which is the blockchain. Because everyone has one of this ledger, it is a distributed ledger. The purpose is to prevent someone from tampering with the record. At the end of the game, it is clear who wins and who loses.

Four men (A, B, C, and D) got together to play mahjong for money. None of them brought any cash, so they asked a beautiful woman (centralized) to keep a book and record who won how much money in each round. , Who lost how much? At the end of the day, everyone uses Alipay or WeChat to pay and settle the ledger. However, if this beauty made a mistake in accounting or was bribed by one of the four people in advance to make a mistake on purpose, there is no guarantee that the outcome of this game will be fair, just, and reasonable. ,dont you agree? then what should we do? If you "play mahjong", you can use "blockchain" as the game rules and adapt it as follows:

Four men (A, B, C and D) got together to play mahjong for money. No one brought any cash. B said Let the beauty she brought keep accounts. A said that none of us knew this beauty, so the four of them, A, B, C, and D, agreed that everyone would keep accounts at the same time (decentralized) on their mobile phones (blockchain nodes) for each game. ), after finally playing mahjong and paying with electronic money directly on the mobile phone, everyone checked the accounting results. The accounting results should have been the same.

Assume that the original result is the account recorded on A’s mobile phone: B owes A 10 yuan. However, the record on B's mobile phone shows that there is no debt, but the other two people (C and D) have the same accounting as A, so the settlement is still based on the majority rule. In addition, everyone has a bad impression of B's ​​integrity. Next The first time I play mahjong, I won’t take B to play with me.

Unless B bribes two people (C and D) in advance to deliberately cheat, but the cost of B bribes them is 100,000 yuan (10,000 times the default of 10 yuan), then in common sense, B only You can choose to give up because the cost of counterfeiting is too high.

Assume that even if B is secretly willing to pay a high price of 100,000 yuan to buy C and D to do this silly cat transaction with huge losses during the card game, the rules of the blockchain are to keep accounts based on timestamps. Yes, it turned out that B owed A 10 yuan in the account at 1 p.m., that is, when C and D revised the account at 3 p.m., the timeIt is irreversible and can only be remembered as 3 o'clock in the afternoon, which does not comply with the rules of the game.

In fact, in 2017 the blogger has developed a set of Mahjong coins

China’s earliest blockchain project: a group of four miners, first starting from 148 random numbers The miner who collides with the correct hash value of 14 numbers can obtain an accounting right incentive. Since distributed accounting requires the consensus of several other miners, each accounting transaction takes about ten minutes.

Understanding the Internet Blockchain in One Article 2

1. Before the birth of Bitcoin, 5 Internet technologies that will have a significant impact on the future of the blockchain

In 1969, the Internet was born in the United States. Since then, the Internet has expanded from four research institutions in the United States to the entire planet. In terms of application, it has expanded from the earliest military and scientific research to all aspects of human life. In the nearly 50 years since the birth of the Internet, five technologies have been of particularly great significance to the future development of blockchain.

1. The TCP/IP protocol born in 1974: determines the position of blockchain in the Internet technology ecosystem

In 1974, the most critical step in the development of the Internet was taken by The TCP/IP protocol, the core communication technology of the Internet jointly developed by American scientists Vinton Cerf and Robert Kahn, was officially launched.

This protocol enables the transmission of information between different computers and even different types of networks. All computers connected to the network can communicate and interact as long as they comply with this protocol.

In layman's terms, Internet data can travel tens of thousands of kilometers to reach the computer users who need it. This is mainly because the Internet world has formed a unified information dissemination mechanism. That is to say, Internet devices follow a unified law-TCP/IP protocol when disseminating information.

Understanding the TCP/IP protocol is of great significance to mastering the Internet and blockchain. After the invention of TCP/IP in 1974, the entire Internet was between the underlying hardware devices, the intermediate network protocols and the network Addresses have always been relatively stable, but an endless stream of innovative applications are emerging at the top application layer, including news, e-commerce, social networks, QQ, WeChat, and blockchain technology.

In other words, in the technical ecology of the Internet, blockchain is a new technology at the top layer of the Internet - the application layer. Its emergence, operation and development have not affected the underlying infrastructure and communication protocols of the Internet. , is still one of the many software technologies that operates according to the TCP/IP protocol.

2. Cisco router technology born in 1984: an imitation of blockchain technology

In December 1984, Cisco was established in the United States. The founder was a professor from Stanford University. A couple, Computer Center Director Leonard Posak and Business School Computer Center Director Sandy Lerner, designed a networking device called a "multiprotocol router."equipment and put it into the communication lines of the Internet to help data accurately and quickly reach the other end of the Internet thousands of kilometers away.

In the entire Internet hardware layer, tens of millions of routers are busy working, directing the transmission of Internet information. An important function of Cisco routers is that each router saves a complete Internet device address table. Once something happens Changes will be synchronized to tens of millions of other routers (theoretically), ensuring that each router can calculate the shortest and fastest path.

When you see the operation process of the router, you will feel very familiar. That is the important feature of the blockchain later. The significance of understanding the router lies in the important features of the blockchain. It has been implemented on the router in 1984. For the router, even if the node device is damaged or attacked by hackers, it will not affect the transmission of the entire Internet information.

3. The B/S (C/S) architecture that was born with the World Wide Web: the opponent of the blockchain and the target of attempted subversion

The World Wide Web is referred to as the Web and is divided into Web clients and server. All updated information is only modified on the Web server. Thousands, tens of thousands, or even tens of millions of other client computers do not retain the information and only obtain the information data when accessing the server. This structure is also often referred to as the Internet B/S architecture is a centralized architecture. This architecture is also the most important architecture of the current Internet. Internet giants such as Google, Facebook, Tencent, Alibaba, and Amazon have all adopted this architecture.

Understanding the B/S architecture will be of great significance to the subsequent understanding of blockchain technology. The B/S architecture is that data is only stored in the central server, and all other computers obtain information from the server. Blockchain technology has tens of millions of computers without a center, and all data will be synchronized to all computers. This is the core of blockchain technology.

4. Peer-to-Peer Network (P2P): Blockchain The father of the chain and its technical basis

Peer-to-peer network P2P is another Internet infrastructure corresponding to C/S (B/S). Its characteristic is that multiple computers connected to each other are connected to each other. In a peer-to-peer position, there is no distinction between master and slave. A computer can be used as a server, setting shared resources for use by other computers in the network, and as a workstation.

Napster is one of the earliest P2P systems, mainly used for music resource sharing. Napster cannot be regarded as a true peer-to-peer network system. On March 14, 2000, a message was posted on the Slashdot mailing list of the underground hacker site in the United States, saying that AOL's Nullsoft department had released Gnutella, an open source Napster clone software.

In the Gnutella distributed peer-to-peer network model, each networked computer is functionally equivalent, serving as both a client and a server, soGnutella is known as the first true peer-to-peer network architecture.

In the past 20 years, some Internet technology giants such as Microsoft and IBM, as well as liberals, hackers, and even criminals who infringe intellectual property rights, have continued to promote the development of peer-to-peer networks. Of course, those on the Internet want to strengthen information sharing. The idealists also put a lot of enthusiasm into peer-to-peer networks. Blockchain is a software application based on a peer-to-peer network architecture. It is a benchmark application for peer-to-peer networks trying to break out from the silence of the past.

5. Hash algorithm: the key to generating Bitcoin and tokens (tokens)

The hash algorithm converts numbers of any length into fixed-length values ​​using a hash function. Algorithms, famous hash functions such as: MD4, MD5, SHS, etc. It is a member of the family of cryptographic functions defined by the American National Institute of Standards and Technology.

This family of algorithms is crucial to the functioning of the entire world. From Internet application stores, emails, anti-virus software, to browsers, etc., all of them are using secure hashing algorithms. It can determine whether Internet users have downloaded what they want, and it can also determine whether Internet users are involved in man-in-the-middle attacks or network attacks. Victim of a phishing attack.

The process of blockchain and its application to generate new coins from Bitcoin or other virtual currencies is to use the function of the hash algorithm to perform operations to obtain numbers that meet the format requirements, and then the blockchain program gives Bitcoin rewards.

Mining, including Bitcoin and tokens, is actually a small mathematical game built with a hash algorithm. However, because of the fierce competition, people all over the world used powerful servers to perform calculations in order to get the rewards first. As a result, many computers on the Internet participated in this little mathematical game, which even consumed more than 40% of the electricity in some countries.

2. The birth and technical core of blockchain

The birth of blockchain should be the most unusual and mysterious invention and technology in the history of human science, because apart from blockchain, So far, there is no major invention in the history of modern science whose inventor cannot be found.

On October 31, 2008, Bitcoin founder Satoshi Nakamoto (pseudonym) published a paper on the cryptography mailing group - "Bitcoin: A Peer-to-Peer Electronic Cash System". In this paper, the author claims to have invented a new electronic currency system that is not controlled by governments or institutions. Blockchain technology is the basis for supporting the operation of Bitcoin.

The preprint address of the paper is at http://www.bitcoin.org/bitcoin.pdf. From an academic point of view, this paper is far from a qualified paper. The main body of the article is composed of 8 flow charts. It is composed of corresponding explanatory text, no nouns and terms are defined, and the format of the paper is also very irregular.

In January 2009, Satoshi Nakamoto released an application case of blockchain on the SourceForge website - the open source of the Bitcoin systemsoftware, after the open source software was released, it is said that Satoshi Nakamoto mined approximately 1 million Bitcoins. A week later, Satoshi Nakamoto sent 10 Bitcoins to cryptography expert Hal Finney, which also became the first in the history of Bitcoin. A deal. With the booming development of Bitcoin, research on blockchain technology has also begun to show explosive growth.

It is indeed difficult to explain the blockchain to the public completely and clearly. We use Bitcoin as the object to introduce the technical characteristics of the blockchain as simply as possible but in depth.

1. Blockchain is a peer-to-peer network (P2P) software application

As we mentioned before, at the beginning of the 21st century, the Internet formed two major types of applications. Architecture, centralized B/S architecture and non-centered peer-to-peer (P2P) architecture. Many Internet giants such as Alibaba, Sina, Amazon, etc. all have centralized B/S architecture. Simply put, it is data Put it in a giant server, and our ordinary users can access the servers of Alibaba, Sina and other websites through mobile phones and personal computers.

Since the beginning of the 21st century, there have been many software applications for freely sharing music, videos, and paper materials. Most of them use a peer-to-peer network (P2P) architecture, that is, there is no central server, everyone's personal computer They are all servers and clients, with equal status. However, this type of application has never become popular. The main reasons are large resource consumption and intellectual copyright issues. Blockchain is a software application in this field.

2. Blockchain is a peer-to-peer network (P2P) software application that synchronizes information across the entire network

Peer-to-peer networks also have many application methods. In many cases, everyone is not required to Each computer keeps the same information. Everyone only stores the information they need, and downloads it to other computers when needed.

However, in order to support Bitcoin financial transactions, the blockchain requires that every transaction that occurs must be written into historical transaction records and change information be sent to all computers with Bitcoin programs installed. Every computer with Bitcoin software installed maintains the latest and complete Bitcoin historical transaction information.

The characteristics of blockchain's network-wide synchronization and network-wide backup are often referred to as blockchain information security, and the source cannot be changed. Although it is still not absolutely safe in practice, when the number of users is very large, it does have certain security advantages in preventing information tampering.

3. Blockchain is a peer-to-peer (P2P) software application that uses a hash algorithm to generate "tokens" to synchronize information across the entire network

Area The first application of blockchain is the famous Bitcoin. When discussing Bitcoin, a term that is often mentioned is "mining". So what exactly is mining?

The metaphor is that the blockchain program gives the miners (players) 256 coins, numbered 1, 2, 3...256. Each time a Hash operation is performed, it is like a toss.Coins, 256 coins are thrown at the same time. After landing, if all the coins with the first 70 numbers happen to be heads. The miner can tell the blockchain program this number, and the blockchain will reward the miner with 50 Bitcoins.

From the perspective of software programs, Bitcoin mining is a mathematical game built using the hash SHA256 function. The blockchain first stipulates a winning mode in this small game: a 256-bit hash number is given, but the last 70 bits of the hash number are all 0, and then the player (miner) continuously enters various numbers. Give the hash SHA256 function and see if you can use this function to get a number with 70 zeros. If you find one, the blockchain program will reward the player with 50 Bitcoins. Actual mining and rewards are more complex, but the above example expresses the core process of mining and obtaining Bitcoin.

When Bitcoin was born in 2009, each bounty was 50 Bitcoins. Ten minutes after its birth, the first batch of 50 Bitcoins was generated, and the total currency amount at this time was 50. Subsequently, Bitcoin increased at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the bounty is halved to 25. When the total amount reaches 15.75 million (new output is 5.25 million, which is 50% of 1050), the bounty is further halved to 12.5. According to the design of the Bitcoin program, the total number of Bitcoins is 21 million.

From the above introduction, Bitcoin can be seen as a guessing game based on a peer-to-peer network architecture. The Bitcoin information rewarded for each correct guess will be transmitted to all players and recorded. into each player's history database.

4. Smart contracts, tokens, ICOs and blockchain basic platforms generated by blockchain technology due to the rise of Bitcoin

From the above introduction, Bitcoin technology It is not a new technology falling from the sky, but a clever combination of various original Internet technologies, such as peer-to-peer network architecture, network-wide synchronization of routing, and network security encryption technology. It can be regarded as a combination of innovative algorithm games. .

Because Bitcoin can be exchanged for legal currency, purchased in kind, and made huge profits through appreciation, the whole world is not calm. With the attitude that if you can do it, I can do it, many people have created their own imitation Bitcoin software applications. At the same time, taking advantage of the difficulty for the government to regulate peer-to-peer networks, various altcoins exploded together with Bitcoin. There have been many incidents of fraud and absconding, which have gradually attracted the attention of governments around the world.

Blockchain basic platform: It is still quite technically difficult to create currency using the blockchain technology framework. At this time, basic technology platforms such as Ethereum, the blockchain basic platform, have emerged, making it convenient for ordinary people. Create a "Bitcoin"-like software program, each showing its magical powers, inviting people to join the game to mine coins, speculate on coins, and gain profits from it.

Passes or tokens: If each "Bitcoin" and "Altcoin" uses a hash algorithm to create a guessing game, it will generate its own "currency".When referring to "coin", this "currency" is collectively referred to as "pass" or "token".

ICO: Since Bitcoin and Ethereum have opened up exchanges with legal currencies in various countries, when other new virtual currencies are issued, Only Bitcoin and Ethereum are allowed to purchase new coins issued. This process of issuing coins is called ICO. The emergence of ICO has amplified the transaction volume of Bitcoin and Ethereum. At the same time, many ICO projects are completely based on nihilistic projects, resulting in A large number of fraud cases occur frequently. This has further deepened society's negative understanding of the virtual currency generated by the blockchain.

Smart contract: It can be regarded as a software function on the blockchain and is an auxiliary function on the blockchain. The specific functions of various virtual currency transaction programs are like the fund custody of Alipay on Taobao. When a user receives the goods and confirms them on Alipay, the funds are automatically paid to the buyer and the owner. The smart contract is in Bitcoin Other blockchain applications also assume this intermediary payment function.

3. The historical status and future prospects of blockchain technology in the Internet

1. Blockchain is in the Internet Where is the technology? It is a new software and architecture at the top level.

We mentioned in the previous introduction to TCP/IP that blockchain and browsers, QQ, WeChat, online game software, mobile phones Like APP, it is a software form of the top layer of the Internet - the application layer. Its operation still relies on the TCP/IP architecture system to transmit data. But unlike most application layer software, it does not use C/S (B/S) The central software architecture. Instead, it adopts an uncommon peer-to-peer network architecture. From this point of view, the blockchain cannot subvert the Internet infrastructure.

2. Who does the blockchain want to subvert? Subvert the B/S (C/S) structure of the World Wide Web.

It attempts to subvert the B/S, C/S structure of the World Wide Web that was actually born in 1989. As mentioned before. Due to the European Union in 1989 Physicist Tim Berners-Lee invented the World Wide Web and gave up applying for a patent. In the past 30 years, companies including Google, Amazon, Facebook, Alibaba, Internet, Tencent and other companies have used the B/S (C/S) structure of the World Wide Web , grew into an Internet giant.

In their headquarters, a powerful central server cluster was established to store massive amounts of data. Hundreds of millions of users obtained the data they needed from the giant servers, which also led to the later cloud With the emergence of computing, Internet giants opened up their unused central server resources to further absorb data from enterprises, governments, and individuals. Centralized Internet giants have an increasing influence on the world, countries, and Internet users.

The goal of blockchain is to try to reduce the influence of Internet giants by distributing data to each Internet user’s computer. It can be seen that the real opponent of blockchain and what it wants to subvert is the birth of 1990 B/S (C/S) structure. But whether it can be subverted depends on its technical advantages and bottlenecks.

3. Technical flaws of the blockchain: Dilemmas brought about by the pursuit of complete equality and freedom

The technical flaws of the blockchain first come from its peer-to-peer network architecture. For example, currently Taobao It has a B/S structure, and massive data is stored in the Taobao server cluster computer room. Hundreds of millions of consumers go to the Taobao server website through their browsers to obtain the latest information and historical information.

If blockchain technology is used, hundreds of millions of people will retain a complete Taobao database on their personal computers or mobile phones. Every time a transaction occurs, it will be synchronized to hundreds of millions of other users. This is completely unachievable in reality. The amount of data transferred and stored is too large. It is equivalent to setting up and running hundreds of millions of Taobao websites at the same time.

Therefore, blockchain cannot be applied to projects with large amounts of data, and even smaller website projects will have difficulty using blockchain. By 2018, Bitcoin had been running for nearly 10 years, and the accumulated transaction data had brought the entire system to collapse.

So the blockchain has adopted many alternative methods, such as establishing relay nodes and lightning nodes. These two concepts can also make people confused. In layman’s terms, the blockchain will ask it for The subversive object B/S structure has been studied, and a data server center has been established to become the relay node of the blockchain, which can also be accessed with a browser-like terminal. This is the lightning node of the blockchain.

This change can alleviate the technical shortcomings of the blockchain, but it does make the blockchain what it opposes, centralization. It can be seen that pure blockchain technology has major flaws due to its technical characteristics and cannot be widely used like the World Wide Web. If the technology is upgraded and some parts adopt a B/S (C/S) structure, the blockchain will become centralized. The information node no longer maintains the dream when it was born.

4. Looking at the future prospects of blockchain from the Internet brain model

We know that the Internet generally refers to the Internet that connects computer networks around the world. On this basis The development of a global Internet network covering the whole world is called the Internet, which is a network structure that is interconnected.

Since the birth of the Internet in 1969, humans have innovated in the Internet field from different directions, and there is no unified plan to build the Internet into a structure. When the wheel of time reaches 2017, with the advent of artificial intelligence, With the vigorous development of science and technology such as the Internet of Things, big data, cloud computing, robots, virtual reality, and the industrial Internet, when humans look up to see the giant systems they have created, the model and architecture of the Internet brain have become increasingly clear.

Through nearly 20 years of development, relying on the B/S and C/S structures of the World Wide Web, Tencent QQ, WeChat, Facebook, Weibo, and Twitter Amazon have developed structures similar to neuron networks. Internet devices, especially personal computers and mobile phones, map personal data and functional space on the giant's central server through the software on the device, allowing them to add friends, communicate and transfer information. Internet giant passesWe upgrade the software of the central server cluster and continuously optimize the software versions of hundreds of millions of terminals. In the neurological system, this is a standard central nervous system structure.

The birth of the blockchain provides another neuron model. Instead of uniformly managing neurons in the centralized services of giants, each terminal, including personal computers and personal mobile phones, becomes an independent neuron node. , retaining an independent data space and synchronizing mutual information. In the neurological system, this is a distributed neural structure with no center and multiple neural nodes.

Interestingly, these two different types of neural structures appear in the development of the nervous system. In lower organisms, blockchain-like neural structures have appeared. There are multiple ganglia with the same functions, all of which can command body activities and reactions. However, as organisms evolve, these ganglia gradually merge. When they evolve into higher In biology, the central nervous system appeared, which contains a large number of neurons that interact with each other.

4. Judgment on the future status of blockchain in the Internet

1. Understanding of Bitcoin: a guessing game based on peer-to-peer network architecture (P2P), Through clever financial and public opinion operations, it has become a "world currency" that is not subject to government supervision.

2. Understanding of blockchain: a peer-to-peer (P2P) software application that uses a hash algorithm to generate "tokens" to synchronize information across the entire network.

3. Blockchain has specific uses, such as large-scale election voting, large-scale gambling, financial transactions that circumvent government financial supervision, etc. It still has irreplaceable uses.

4. In more cases, blockchain technology will rely on the B/S and C/S structures of the Internet to achieve functional expansion, but overall it is still a supplement to the existing technology of the Internet. Most of the application scenarios currently envisaged by blockchain can be implemented using B/S and C/S structures, with higher efficiency and more mature technology.

5. Whether from the perspective of information transmission efficiency and resource consumption, or from the evolution of the nervous system, blockchain cannot become the mainstream architecture of the Internet, let alone a subversive and revolutionary leader of the future Internet.

6. Of course, Internet giants developed with B/S and C/S structures also have their problems, but these can be gradually solved through commercial and political methods in the future.

Ⅸ The future development prospects of blockchain

1. Blockchain has become the forefront of global technological development and opened up a new track for international competition. Blockchain will become a new key infrastructure to further accelerate the development of the digital economy, lead a new round of global technological and industrial changes, and become the "source" of technological innovation and model innovation. The world's major developed countries will further pay attention to blockchain technology, intensively introduce relevant policy plans, increase industrial support and guidance, and enhance the competitiveness of their country's blockchain technology and industry.
2. The digital currency bubble gradually cools down with the spread of the concept of blockchain technology., more and more people will realize that Bitcoin is not equivalent to blockchain, various air coins will be gradually eliminated, and blockchain technology innovation will return to a more rational track. Technical features such as decentralization, multi-party collaboration, and anti-calculation tampering will be highly valued by relevant industries. Some industries with strong innovation capabilities will continue to emerge with blockchain applications that have been transformed based on industry characteristics.

Ⅹ What is blockchain technology? What exactly is blockchain?

Blockchain technology is one of the top ten typical judicial technology applications on the Internet. Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms.

Blockchain is an important concept of Bitcoin. In fact, it is a decentralized database. Blockchain, as the underlying technology of Bitcoin, is a series of data blocks generated using cryptographic methods. Each data block contains a batch of Bitcoin network transaction information, which is used to verify the validity of its information (anti-counterfeiting) and generate the next data block.

Blockchain originated from Bitcoin. On November 1, 2008, a person who called himself Satoshi Nakamoto published the article "Bitcoin: A Peer-to-Peer Electronic Cash System", which elaborated on P2P network technology, encryption technology, timestamp technology, and block technology. The concept of electronic cash system framework such as chain technology marks the birth of Bitcoin.

The birth of blockchain:

p>

The concept of blockchain was first proposed by Satoshi Nakamoto in 2008. In the following years, blockchain became the core component of the electronic currency Bitcoin: a public account for all transactions. By using peer-to-peer networks and distributed timestamp servers, blockchain databases can be autonomously managed.

The blockchain invented for Bitcoin made it the first digital currency to solve the problem of repeated consumption. Bitcoin design has become a source of inspiration for other applications. On December 20, 2016, the Digital Currency Alliance-China FinTech Digital Currency Alliance and FinTech Research Institute were officially established.
