A. What is the impact of blockchain technology on modern society

Jinwowo Network Technology shares the impact of blockchain on society:
In the future, blockchain will be applied in any field and will have a great impact on human life. Blockchain application projects are roughly divided into: existence proof, smart contract, Internet of Things, identity verification, prediction market, asset trading, e-commerce, social communication, file storage, data API (application programming interface), etc.
If blockchain technology can be used to save it, there will be historical personal medical data, and the data will be available for future medical treatment or planning for one's own health, and the real owner of this data is the patient himself. Rather than a hospital or some third-party agency. In addition, these data have strong privacy, and the use of blockchain technology can also help protect patient privacy.

B. How can blockchain cover other industries besides finance?

Blockchain is one of the most challenging innovations in the field of financial technology (Fintech), because blockchain Chain has fundamentally subverted the inherent logic, operating model and business scope of traditional finance, breaking through the limitations of numerous conventional rules and regulations, and entering a series of new application fields that were previously unreachable.
Blockchain is called a disruptive technology that will reconstruct the key underlying infrastructure of Internet finance and even the entire financial industry. Its value in the financial field is waiting for people to discover. Specific applications are as follows:
1. Applications in the banking industry
Wallet and payment are the first areas where blockchain technology has been involved, but this is also the traditional business scope of the banking industry. What changes can the arrival of blockchain technology bring?
Cross-border payment - application case:
Circle Circle, founded in October 2013, aims to make Bitcoin "simple and easy to operate, similar to Gmail (Google Mail), Skype (Microsoft's Internet phone) and other customers service tools like that” and the company quickly received a large amount of financing. In mid-2014, it received an investment of US$27 million, becoming one of the most well-funded companies in the field of digital cryptocurrency.
In 2015, Goldman Sachs and IDG Capital Partners led the investment, raising $50 million in funding for Circle. In June 2016, Circle received US$60 million in investment led by Chinese investors, and announced that it had established an independent company in China, Circle China, established a local team, and reached strategic cooperation with Internet and Everbright.
Circle utilizes Bitcoin blockchain transactions to provide instant and free fund transfers around the world. Circle hopes to use Bitcoin as a free Internet payment network to enable the smooth flow of national legal currencies around the world without any hindrance. By partnering with overseas companies like IDG, Circle can provide financial services to users using legal currencies in various countries..
Despite the complex regulatory structures of payment systems in various countries, cooperation between these countries has made progress. In April 2016, Circle received the first electronic currency license issued by the British Financial Conduct Authority (FCA), which attracted widespread attention in the industry. Subsequently, Circle announced the establishment of a partnership with Barclays Bank and officially entered the British market. Since then, British consumers can enjoy services such as fast transfer payments and Bitcoin buying and selling like American consumers.
In order to make it more convenient for users, Circle cooperates with Apple. In the iOS 10 system, Apple’s iMessage supports users to use Circle’s Bitcoin payment system. Circle CEO Jeremy Allaire said:
“Consumers will benefit from iMessage allowing payment services to be connected. It would be difficult to install an APP alone for payment, and it would be difficult to share it with friends. Transfer payments between places also require a complex setup process, but directly connecting to the iMessage service is much simpler.”
On September 13, 2016, Circle announced that users can pay to anyone in the world through iMessage. people.
The advantages of blockchain in cross-border payments: low cost, real-time transactions, and high security.
Smart Bills—Application Case:
Complex Beauty Blockchain Bill Project Bills and blockchain technology can be well combined. After adopting the decentralized distributed ledger of blockchain, it has changed the current situation. Some system storage and transmission structures have established a more secure operating mode to solve the problem of counterfeit bills.
The process of the bill from its creation to its demise is completely reflected through the timestamp. Its history can be traced, which makes this model have a new continuous endorsement mechanism and truly reflects the transfer process of the rights of the bill.
The domestic Hangzhou Complex Beauty Blockchain Research Center has also initially developed an open source project for a blockchain lending bill exchange based on Ethereum, which integrates multiple segments such as finance, catering, business management, and express delivery tracking. The concept of applying blockchain technology in the field. As shown in the figure, the open source project of the Complex American Blockchain Network Lending Exchange is an online lending exchange that applies blockchain technology and can complete online transactions claiming to be 150,000 per second with no handling fees.
Blockchain-based bill business has four advantages:
From the perspective of moral hazard, "one vote sells more" in paper bills and the payment and endorsement in electronic bills are not synchronized from time to time. However, due to the non-tamperable timestamp and the publicity of the entire network, the blockchain will not cause any defaults once the transaction is made, regardless of whether it is a paper ticket or an electronic ticket.
From the perspective of operational risks, since the electronic bill system is operated in a centralized manner, once there is a problem with the central server, it will have catastrophic consequences for the entire market. At the same time, the access to corporate online banking will transfer more risks to Bank’s own network security issues, the entire risk chain will become longer and longer. With the help of distributed high fault tolerance and asymmetric encryption algorithms in the blockchain, the risk caused by human operations will be almost zero.
From the perspective of credit risk, the collection and assessment of the credit of all participants can be achieved with the help of blockchain data, and real-time control can be carried out.
From the perspective of market risk, a large number of asset mismatches in the intermediary market not only lead to their own losses, but also tie up the interests of banks. The programmability of the blockchain can not only effectively control the balance of the assets and liabilities of participants , and can also rely on the characteristics of data transparency to promote the authenticity of the entire market transaction price response to capital demand, thereby forming a more realistic price index, which is conducive to controlling market risks.
Bank settlement - application case: VISA
Bank settlement refers to the act of collection and payment through the transfer of funds in a bank account, that is, the bank accepts the entrustment of the customer to collect and pay on behalf of the customer, and transfers the money from the deposit account of the paying unit , transferred to the deposit account of the receiving unit to complete the settlement of claims and debts between customers or the allocation of funds. In this process, banks serve as both a medium for commodity exchange and an intermediary for clearing funds in social and economic activities.
Unlike domestic banks, which mainly rely on the difference between deposits and loans to make profits, half of the profits of multinational banks come from intermediary settlement business. For them, if they open up new business areas and reasonably reduce settlement costs, it is directly related to their fundamentals. .
VISA is the world's largest credit card company. There is no doubt that the rise of digital cryptocurrency will inevitably have an impact on its credit card payment business. However, VISA has not always been resistant to electronic currency and blockchain, but has adopted an open attitude.
In October 2015, VISA and DocuSign jointly launched a "proof of concept" project using the Bitcoin blockchain to record and store car rental data. The project combines DocuSign’s digital transaction management (DTM) platform and electronic signature solutions with VISA’s secure payment technology. It allows consumers to configure rental, insurance and other daily purchases in the car, such as parking fees and tolls, and users can pay directly with VISA cards.
Peripheral applications do not satisfy VISA. In the same year, VISA cooperated with Coinbase to launch the first Bitcoin debit card that can be used in the United States. On November 30, at the UnBound conference in London, the VISA European Innovation Laboratory demonstrated a "proof of concept" remittance application through which people can remit money on the Bitcoin blockchain.
In September 2016, VISA launched Interbit, an inter-bank settlement and payment system based on blockchain technology in cooperation with digital payment startup BTL Group, to evaluate whether blockchain technology can facilitate international transfers between banks. Reduce costs, settlement time and credit risk.
A series of major actions in the past two years can be seen: VISA began to recognize the blockchainWe are working hard to make blockchain technology a powerful tool to expand its sphere of influence.
The advantages of blockchain in bank settlement: safe, convenient and intelligent.
In addition to using blockchain technology to transform existing businesses, major banks around the world have also launched their own encrypted digital currency plans to reduce their operating costs.
Advantages of blockchain in banking digital currency: reducing costs.
2. Securities investment market application
Securities trading - application case: Linq
The securities trading market is an important application field of blockchain. The application of blockchain technology can not only speed up clearing and settlement, but also reduce the number of books that financial institutions need to maintain and ensure more accurate audit trails.
NASDAQ is the earliest pioneer in the securities exchange market. In the second half of 2015, it launched Linq, a trading platform based on Bitcoin trading technology for trading of primary market companies. As shown in the figure below, Linq can record equity transactions before a company's IPO. It can track corporate equity transactions, shareholder and investor information, etc., and is very valuable for asset analysis in the private equity market.
Fredrik Voss, head of blockchain strategy at Nasdaq, is convinced that the high efficiency provided by blockchain technology will greatly enhance Linq’s advantages as a private equity trading platform. . So far, there is no technology that can truly keep people away from paper work, and blockchain technology will make it a big step forward, significantly reducing the possibility of errors compared to manual processing.
The advantages of blockchain in securities transactions: speed up settlement, simplify accounts, and facilitate tracking and auditing.
Equity Crowdfunding - Application Case: Xiaoyi
Funding has always been a gap between creative ideas and entrepreneurship, and it was this gap that gave birth to the world's first crowdfunding platform - Kickstarter. The way Kickstarter works is a typical platform business model. The users of the platform are on one side people who are eager to create and create, and on the other side are people who have some funds and are willing to fund new ideas. Both parties share the same desire. They all hope that new ideas will become reality and achieve continuous promotion.
Crowdfunding platforms based on blockchain technology can raise funds by creating their own digital cryptocurrency or digital assets, and by distributing their own "digital equity" to early backers, investors receive support for startups. Certificate of shares.
Blockchain crowdfunding platforms usually have a three-layer structure:
The lowest layer is the blockchain network, which builds a decentralized distributed ledger;
The middle layer is business logic Combined with the blockchain to jointly establish an account center, equity registration, equity certificates, equity transactions, equity management and other functionsCapable;
The top layer provides services provided to customers by each crowdfunding platform.
In China, Xiaoyi is the first company to use blockchain technology to register company equity. Although this is an innovation, it is not easy to achieve compliance with Chinese laws and connect with the physical world in terms of underlying logic and various details. After in-depth research and analysis of my country’s current legal environment, Xiaoyi has the potential to become a practical blockchain application.
Xiaoyi is a blockchain protocol based on blockchain technology that registers, issues, manages, and trades various equity shares through a peer-to-peer network. In the early stage, the equity of unlisted companies will be used as the entry point to provide digital share incentive solutions for startups and equity management solutions for equity crowdfunding companies. In the future, it will transition to tradable equity, that is, "blockchain IPO", which will gradually become blurred. The boundary between unlisted companies and listed companies.
The advantages of blockchain in equity crowdfunding: transcending time and space constraints, optimizing crowdfunding organization, and rational distribution of equity and interests.
3. Application in Insurance Industry
Policy Sales—Application Case: Bubi Aviation Accident Insurance
Traditional aviation accident insurance has always had problems such as insurance fraud and price hikes by intermediaries. As the saying goes, "the wool comes from the sheep", it is ultimately passed on to consumers. Blockchain technology can provide effective means to solve these problems.
On July 29, 2016, Bubi Blockchain cooperated with Sunshine Insurance to launch the "Blockchain + Aviation Accident Insurance Card", which is the first domestically placed mainstream financial assets on the blockchain. circulation.
Most aviation accident insurance will only make claims when an aircraft accident occurs, so in most cases it is not easy to detect when customers buy fake insurance. In order to prevent the purchase of "fake insurance policies", Bubi Blockchain relies on its multi-party data sharing characteristics to trace the entire process of card slips from the source to the customer. All parties can not only check the authenticity of the card slips, but also ensure that the card slips are authentic. The authenticity of the order can also facilitate subsequent processes, such as claims settlement, etc.
In order to prevent middlemen from raising prices and passing them on to consumers, aviation accident insurance cards are set up on the Bubi blockchain. Without middlemen, the price of insurance cards will drop significantly. According to data, this product can be purchased for 60 yuan per copy and can be used by 20 people. Each time, you can get aviation accident protection of up to 2 million yuan, which is equivalent to spending 3 yuan each time to get 2 million yuan of protection.
The advantages of blockchain in the insurance industry: authenticity and transparency, information security, traceability, clear claims process, and low cost.

C. What are the applications of blockchain in other industries

1. Monetary and fiscal policies. Central banks of many countries, including China, are paying attention to blockchain technology. It is possible to record currency in every transaction and know who and which industries are transferring currency. The central bank can use blockchain technology and big data analysis to implement precise fiscal and monetary policies. In the past, after the central bank issued currency, it could only rely on market reaction andJudging from past experience and macro data, monetary and fiscal policies tend to lag behind. At the same time, blockchain can prevent money laundering, which is more efficient and scientific than the demonetization order of the Modi government in India.

2. For the clearing and settlement of financial transactions, banks essentially serve as safe warehouses and transmission hubs for funds, and blockchain has basically similar functions as a digital, secure and tamper-proof ledger. . This means that the disruptive wave of blockchain-based fraud may have a profound impact on banks in the future. In fact, UBS and the British bank Barclays have already begun experiments using blockchain technology to speed up back-end settlement functions. Some banks even say that blockchain can reduce middleman costs by at least $20 billion.

3. E-commerce payments and transfers. In a recent report, the World Economic Forum believed that decentralized payment technology may change the money transfer business that has remained unchanged for more than 100 years. system organization. Blockchain has the ability to bypass these clunky systems and create a more straightforward payment process. This will cross borders, have no intermediaries, cost very little, and most importantly, transfers can be completed almost instantaneously.

D. 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>

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 individual 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. SomeIndustry 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! Blockchain technology can be applied in many fields, including finance, 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 100The famous companies mainly come from 14 countries and regions, with China accounting 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.

The blockchain financial field is the most widely used

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, and contains huge space for innovation. In the fields of chips, big data, cloud computing and other fields, innovation activities are becoming increasingly active, and innovation elements are constantly accumulating. 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 (each parameterEveryone is a recorder of information, and each person is just a link in the entire information chain) 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)

E. Will blockchain cause banks to disappear?

Blockchain will not cause banks to disappear. Blockchain will only disappear. Improve bank operations.
Currently, some well-known financial institutions around the world have begun to pay attention to blockchain and have conducted corresponding research and development. But banks will only use blockchain and will never let blockchain replace themselves.
The underlying technologies of Bitcoin, Ritecoin, and Litecoin are all blockchains, but no one can replace banks.

F. Why do I say that blockchain technology will change the future of social e-commerce?

Why do I say that blockchain technology will change the future of social e-commerce?

1. What problems does blockchain technology solve?

“People often ask me recently, everyone knows that blockchain makes money, but can you tell me in one sentence, blockchain What problem does this technology solve?”

Although many people know that blockchain technology supports the operation of Bitcoin, when it comes to what problem it really solves, or what blockchain has created What is the value? Many people in the industry are speechless. Because of the ultra-high money-making effect, everyone cannot calmly look at this industry or even this so-called ecology from an investment or technical perspective.

Recently, when I interviewed some "old people in the currency circle", I got a better answer.

“Blockchain technology is the first time in human history that the problem of trust between people has been solved through technical means.”

Through the characteristics of blockchain, we It can be completely tamper-proof, traceable, transactions through smart contracts, etc. Therefore, in theory, everything that needs to solve the problem of trust between people through technical means will most likely require blockchain technology for development and innovation.

2. The Internet era gave birth to social networking and e-commerce

The Internet is a problem in which humans have greatly optimized information transmission through technical means. In the Internet era, business models are roughly divided into three major modules: advertising, e-commerce, and games. Therefore, in the Internet era, there is no doubt about the rise of e-commerce and social networking.

Taking the current highly competitive e-commerce industry as an example, Alibaba and JD.com are both leaders in the field of e-commerce. The e-commerce industry in mainland China has realized e-commerce in the Internet wave. 17 years of explosive development in the business field. WeChat, the largest social software in China and the second largest in the world, has also become an industry leader.

The current Internet industry has gone through the baptism of time, and an obvious oligarchic effect has been formed after the great waves. Today, every oligarch in the e-commerce market has become an industry heavyweight. Of course, there are also situations where it is difficult for a large ship to turn around. In this state. All e-commerce companies are looking for new directions to break through. And many people are eyeing cross-border cooperationSocial e-commerce field.

The two major representatives of social e-commerce are e-commerce based on the Weibo and WeChat ecosystems. At present, the total market share of social e-commerce has reached as high as 14%-20%

Although many people say that the biggest application of blockchain is currency speculation, SEC and other The launch of the project indicates that blockchain technology has the potential to improve the current status of the industry. It is precisely because there are many teams like the SEC that find the integration point between technology and industry and solve the key problems of the industry, which will be the research direction and consensus of the overall blockchain in the future.

G. What exactly is blockchain and what it can do? Let me explain it in layman’s terms~Thank you

1. Blockchain is distributed data storage, point-to-point transmission, consensus mechanism, and encryption. New application models of computer technology such as algorithms.

Blockchain is an important concept of Bitcoin. It is essentially a disintermediated database. As the underlying technology of Bitcoin, it is a series of related cryptographic methods. Each data block contains information about a Bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block.

2. Application

1. Art industry

Ascribe allows artists to use blockchain technology to declare ownership and issue numberable, limited editions. Works can be for any type of artwork in digital form. It even includes a marketplace where artists can buy and sell through their website without the need for any intermediary services.

2. Legal industry

BitProof is the most advanced of the many document timestamp applications that have emerged in recent years, and will make traditional notarization methods a thing of the past. Compared with free versions including Blocksgin and OriginStaemp, BitProof provides more services, including one for intellectual property. Interestingly, BitProof recently collaborated with a San Francisco IT school to put all their students’ academic certificates on the blockchain, completely redefining how diplomas and student certificates are processed and used.

3. Development industry

Colu is the first company to allow other companies to issue digital assets. Their ability to "tokenize" various assets has impressed many people. While the free Bitcoin wallet Counerparty also allows simple tokens to be issued and traded among other wallet holders, Colu's tokens can be configured in various states and types, be able to leave and return to the system, and When storing data on the blockchain is too large, the data can be stored on the BitTorrent network.

4. Real estate industry

They plan to make the entire industry chain process more modern and solve various problems faced by everyone involved in real estate, includingNaming process, land registration, agency intermediaries, etc.

5. Internet of Things

A possible application scenario is: generate corresponding behavior through Transaction, assign an address to each device, and inject a certain fee into the address. Perform relevant actions to achieve Internet of Things applications. Similar to: PM2.5 monitoring point data acquisition, server leasing, web camera data calling, DNS server, etc.

6. Insurance industry

In the past two years, the hottest topic in the technology field must be inseparable from blockchain technology. This underlying technology, which was born out of Bitcoin, has proven its highly secure and reliable architecture and algorithm design with more than 7 years of stable operation. At the same time, it has relied on innovative technologies such as distributed ledgers and smart contracts to upgrade industries in many industries. It opens up a huge space for imagination. Some industry experts even predict that blockchain technology will set off a second Internet revolution.

(7) Will blockchain replace other things? Extended reading:

In 2008, Satoshi Nakamoto proposed in the "Bitcoin White Paper" The concept of "blockchain", and founded the Bitcoin network in 2009, developed the first block, the "genesis block".

The blockchain shared value system was first imitated by many cryptocurrencies, and improvements were made in proof-of-work and algorithms, such as the use of proof-of-stake and SCrypt algorithms. Subsequently, the blockchain ecosystem continued to evolve around the world, with the emergence of initial coin offerings (ICOs), smart contract blockchain Ethereum, asset tokenized sharing economies with “light ownership, heavy usage rights”, and blockchain countries.

Currently, people are using this shared value system to develop decentralized computer programs (Decentralized applications, Dapp) in all walks of life, and build decentralized autonomous organizations and decentralized autonomous communities around the world. (Decentralized autonomous society, DAS).

H. What is blockchain and what role does blockchain play

What is blockchain? What changes will it bring to your future life?

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. It is essentially a decentralized database. As the underlying technology of Bitcoin, it is a series of related cryptographic methods. Each data block contains a batch of Bitcoin network transaction information, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block.

The original English version of the Bitcoin white paper does not actually appear on the blockchainThe word chain of blocks is used instead. In the earliest Chinese translation of the Bitcoin white paper, chain of blocks was translated into blockchain. This is the earliest time when the Chinese word "blockchain" appeared.

The Cyberspace Administration of China issued the "Blockchain Information Service Management Regulations" on January 10, 2019, which will come into effect on February 15, 2019.

In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-tamperable. Unforgeable distributed ledger.

Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, and uses cryptography to ensure data transmission and Access security, a new distributed infrastructure and computing method that uses smart contracts composed of automated script codes to program and operate data.

In fact, to understand it very simply and vividly, we can imagine that everything in life is realized in digital form, including food, clothing, housing, transportation, medical treatment, education, etc., based on the Internet, it can be easily done at home Get it done, no matter where you go to do business or trade, you can completely operate it with your mobile phone. With the continuous development, everything we do can be easily completed online, such as volumetric work, production, planting, etc. Of course, the rise of 5g will bring about the end No one can accurately predict what it is now, but it will definitely bring about earth-shaking changes in life and social form!

Blockchain was born from Satoshi Nakamoto’s Bitcoin. Since 2009, various Bitcoin-like digital currencies have appeared, all based on public blockchains.

The current situation of digital currencies is that a hundred flowers are blooming. Here are some common ones: bitcoin, litecoin, dogecoin, OKcoinetc. In addition to currency applications, there are also various derivative applications, such as NXT, SIA, and BitShares. , MaidSafe, Ripple, Ethereum and many more.

On January 20, 2016, the People’s Bank of China Digital Currency Seminar announced that it had achieved phased results in digital currency research. The meeting affirmed the value of digital currency in reducing the issuance of traditional currency and stated that the central bank is exploring the issuance of digital currency.

Some areas where blockchain can be used can be:

▪ Smart contracts

▪ Securities trading

▪ E-commerce

▪Internet of Things

▪ Social Communication

▪ File Storage

▪ Proof of Existence

▪ Authentication

▪ Equity crowdfunding

The development of blockchain can be compared to the development of the Internet itself. In the future, something called finance-internet will be formed on the Internet, and this thing is based on Blockchain, its precursor is bitcoin, that is, traditional finance starts from private chains and industry chains (local area network), and the bitcoin series starts from public chains (wide area network), both expressing the same concept - digital assets (Digital Asset), and ultimately to An intermediate equilibrium point converges.

The core advantages of the blockchain architecture include:

Any node can create a transaction, and after a period of confirmation, it can reasonably confirm whether the transaction is Effectively, blockchain can effectively prevent problems from happening on both sides. The cost of trying to rewrite or modify transaction records is very high. Blockchain implements two types of records: transactions and blocks. Transactions are the actual data stored on the blockchain, while blocks are records confirming when and in what order certain transactions became part of the blockchain database. Transactions are created by participants using the system in the normal course (in the case of cryptocurrencies, a transaction is created by Bob sending tokens to Alice), while blocks are created by what we call Units of miners are responsible for creation.

So in conclusion, this is undoubtedly a new technology that changes life. In the future, the production activities of the entire society will be carried out with blockchain as the underlying logic, and many things will be within our reach. , coupled with the integration of artificial intelligence and big data, we can easily handle things that seem to be cumbersome now, such as some securities market transactions and intelligent matching of financial management activities.

To put it simply, blockchain is a network computing center that integrates people, property, machines, and goods, and packages it into a whole; putting it on an infrastructure to run the network computing center .

Now the author’s imagination is not big enough to imagine what the future world will be like. I am looking forward to it!

I know a thing or two about this issue. Let’s get to know this mysterious thing - blockchain.

Blockchain is a new type of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm.type application model. Blockchain is an important concept of Bitcoin. It is essentially a decentralized database. As the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods. Each The data block contains information about a batch of Bitcoin network transactions, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block

The more popular it is, the more fake it is to keep the real. First of all, we must first figure out what the real blockchain technology is.

As an example, take buying fruits online.

The process of purchasing fruits online is as follows:

Using blockchain technology and decentralization, the process of purchasing fruits is as follows:

Summary:

1. We found that the original transaction process is: buyers and sellers make transactions, and all key processes are dealing with the payment platform. The advantage of this is that if there is a problem in any link, both sellers and buyers can seek help through the platform and let the platform arbitrate. However, a major bug or hacker attack occurs on the platform, resulting in the loss of all transfer records within a period of time. How to deal with the loss is a troublesome matter.

2. The transaction process using blockchain technology is: everyone’s ledger has exactly the same transaction record. Even if Alipay’s ledger server is broken, the seller’s ledger still exists, and the buyer’s ledger still exists. Still exists. Once this transaction occurs, the traces will never be erased.

This is the core of the blockchain, which is the four words "accounting + accounting".

The development and maturity of blockchain technology cannot be separated from the foundation and foreshadowing of the above new generation of Internet technology. Blockchain is not only a technology, but also provides a service model and solution. , which has played an extremely important role in promoting the further development of the Internet industry.

1. Blockchain + Finance

2. Blockchain + Supply Chain Management

3. Blockchain + Intelligent Manufacturing

4. Blockchain + Public Services

5. Blockchain + Education and Employment

6. Blockchain + Culture and Entertainment

7. Blockchain + payment

8. Blockchain + invoice {Already enabled in Shenzhen}

Traceability and non-tamperability of blockchain , perfectly combined with the inherent nature and needs of the financial industry, which makes the application of blockchain in the field of financial services the most in-depth and relatively mature field so far. Blockchain technology has broad application prospects. future technologyCompetition will definitely be blockchain competition.

It is important to understand blockchain, which is important to see through various pseudo-blockchain scams.

If someone uses a bunch of professional terms to explain blockchain, it will be difficult for you to understand, and they may not really understand it themselves.

Therefore, we first establish a psychological line of defense. Anyone who sells you concepts and uses a lot of unfamiliar technical terms may be a liar. Be very careful!

To understand blockchain, you must know what the core appeal of blockchain is. What do you think you are most worried about in today's highly developed Internet world?

Privacy, yes, privacy. How to protect privacy? You may be monitored at any time, and any of your personal information may be stolen at any time. If personal privacy is not absolutely protected, the Internet will become another pyramid of power. Who is standing on top of the pyramid? He is the smartest technical master, a platform provider, and an information regulator. You and I may be the people at the bottom of this pyramid.

The people who originally invented the blockchain had serious concerns about being completely swallowed up by the Internet, and tried to create an absolutely safe encryption technology to lock up personal privacy. This technology completely subverts traditional encryption technology. In fact, rather than locking up privacy, it is better to tear it into pieces and then distribute the pieces to different people for private keeping. Unless everyone agrees to take the pieces and piece together the complete code, the truth cannot be recreated. This is the first mechanism of blockchain, which is decentralization.

But decentralization alone is not enough. It is also necessary to make those who steal password fragments have nowhere to hide, so that every action of the thief can be recorded indelibly and posted everywhere on the Internet. Diffuse and make it public. This is the second mechanism of the blockchain, the non-anonymous mechanism. Do you think, who snoops into privacy is not sneaky?

In summary, the blockchain is to hide privacy in a decentralized manner, record any actions that reproduce this privacy, and make it public. Seeing this, you may want to applaud the blockchain. Don't worry, how can there be such a good thing in the world? Is there any utopia that is absolutely safe? If blockchain can be realized in an absolute sense, will the existence of the government still be meaningful? Yes, blockchain was originally the embodiment of anarchy. Its ultimate meaning is destined to never be realized. Its survival may have to rely on power, and it is destined to become another beautifully packaged lie and a pretense to deceive others. In this sense, the government must also specify a framework for the development of the blockchain, reconstruct the value of the blockchain, and expel the anti-government and anti-national attempts contained in the blockchain. Some blockchain technologies can be used in concrete applications, but decentralization must not be promoted. In short, we must remain highly vigilant about blockchain. Beauty often hides its sting. Absolutely ideal recipes often turn out to be poison.The person who says he can absolutely protect your privacy and financial security is the real voyeur and vampire.

Perhaps the best way for us to protect privacy is not to have any privacy, to live completely openly, or to live like a sun or a god of wine.

Viewpoint: 1. The concept of blockchain originated from the technical attributes of Bitcoin (distributed data storage and accounting, decentralization, inability to tamper with transaction records, point-to-point information transmission, sharing mechanism...), but Later, some people continued to extend and expand the concept to many commercial fields to facilitate capital speculation. 2. Blockchain in reality (the current blockchain on the market is very confusing), the hype concept is mostly used to make money in the stock market, and there is still a lack of regulatory loopholes. , legal and regulatory issues, etc., and even money laundering (the actual operation of blockchain products is one thing, the capital operation behind it is another). At present, the computer systems around the world cannot meet the characteristics of blockchain attributes. Technical requirements (such as distributed data storage and accounting, decentralization...), network bandwidth, storage technology and computer computing systems cannot meet transaction operation requirements (it is easy to use computer technology to make your network clogged or unable to complete distribution) There are risks arising from practical applications such as formal data storage or transactions being interrupted or delayed at any time. In addition, as far as the current global computer system is concerned, it is easy to crack the underlying program of the blockchain (this is a fatal flaw in the current global computers, 0 and 1 binary logic In addition, if the reverse blockchain mode calculation algorithm is used, it is very easy to crack the blockchain. This reverse calculation mode can also completely tamper with all transaction records. If a true quantum computer becomes available in the future, it can directly break all blockchain computers in seconds. System, Bitcoin mining is a Ponzi scheme, 3. Most of the blockchains currently on the global market are basically capital speculation concepts to make money.

The concept of blockchain has been around for several years. , I heard a blockchain boss say at the beginning of last year that 2018 is the best year for the development of blockchain. After this year, foreign development will fall behind. What is blockchain? In terms of impact, it is like a pig. The large intestine is connected section by section. Blockchain is to connect these blocks together and fix them, using computer and Internet encryption technology to prevent secrets from being leaked to the outside. This technology cannot be explained to non-professionals through professional terms Normally people can’t understand it. I can only explain it with an analogy. Let me give you two examples:

1. Four people, A, B, C and D, play mahjong in a mahjong parlor to gamble, using chips for each game. When the partnership was dissolved, A lost 1,500 yuan, B lost 300 yuan, C won 200, and D won 1,600. As a result, A only had 1,000 yuan, and everyone else settled it, but A still owed D 400 yuan. .Only these four people know about this matter, and these four people are in the same block. There is no proof for what you say, and you won’t write an IOU for this kind of thing. What will you do if A doesn’t pay back the money in the future? Apart from A, B, C and D, there are four people in this matter No one else present knows that if A wants to default on the debt and says he doesn’t owe money at all, only B willThree people, Bing and Ding, know that A has defaulted on his debt, and it is difficult for others to judge whether A owes money and refuses to repay. Therefore, the value of blockchain needs to expand participation. What if these four people were playing mahjong and a dozen friends were watching? Isn’t the cost of defaulting on the loan high? This is real life block. What about extending to the Internet? Then there are endless possibilities and there are many scenarios.

2. If four people, A, B, C and D, do business in a business group of 500 people, this group of 500 people is a big block. Once, A asked B for 10,000 yuan of goods, but did not pay B in time. A said at that time that he would pay B within 3 days. Everyone in the group knows this. If A fails to send money to B within 3 days, then the other 498 business partners in the group will know about it. If A defaults on the debt, his reputation in this business circle will be ruined. affected. This is a block.

Later, A wanted to do business with C. C asked A for goods. A said that you should pay a deposit of 5,000 yuan and the goods will be shipped immediately. C paid 5,000 yuan to A, but A was delayed. Not shipping, everyone in the group knows this, this is another block. When the two blocks are connected, everyone doubts A's credibility. How many times have you done this? Will Mr. A continue to play in the future? This is the value of blockchain.

Blockchain may seem complicated, but it is not complicated at all; it may seem simple, but it is actually very difficult to operate. The blocks are too small and meaningless. If a block wants to grow bigger, privacy and business secrets will be involved. For example, it is inconvenient to talk about falling in love in a large group; for example, it is inconvenient to discuss it publicly in the group (block) beforehand when working together to do big business. However, there are still occasions when blockchain technology is used, such as poverty alleviation work, disaster relief fund management, etc. It is exposed to the sun and everyone knows it and supervises each other. I’ve given these two examples. Do you understand them at all?

[The most core and easy-to-understand introduction to blockchain]

1. How does blockchain create trust? We use "1", "2", and "3" to summarize the characteristics of the blockchain:

- "1" summarizes the blockchain: a trusted distributed database;
>
- "2" core properties: distributed, non-tamperable;

- "3" key mechanisms: cryptography principles, data storage structure, consensus mechanism.

The "distributed" and "non-tamperable" properties ensure the "honesty" and "transparency" of the blockchain, which is the basis for the blockchain to create trust.

2. In terms of industry, it is expected that the financial industry will be dominated by the financial industry in the next 3-5 years, gradually radiating to other real industries, more realistic scenarios will be accelerated, and the industry will develop from "1 to N" to Including entertainment, product traceability, credit reporting, etc.

Future, blockIn addition to using technologies such as side chains, lightning networks, and cross-chains, the chain also needs to be deeply integrated with emerging information technologies such as 5G, artificial intelligence, big data, and the Internet of Things to improve technical performance and off-chain data quality and reduce resource waste.

3. Smart contracts may be the most revolutionary application on the blockchain. If smart contracts are widely used on the blockchain, the economic division of labor will be further refined in the Internet era. Network nodes around the world will directly connect demand and production, and broader social collaboration will be realized.

If the above vision is realized, the combination of blockchain technology and industry is expected to usher in an explosive moment "from 1 to N". Its explosion may not be linear but non-linear. Blockchain Only then can the chain be upgraded from a "trust machine" to an important "engine" leading the industry wave.

Decentralization. Prevent cheating. It used to be that one person kept accounts and could make changes. Now there are 50 people. Each person records an entry and everyone has a record in the account book. Can you make changes to all 50? All 50 ledgers are valid unless they are all changed. So it's very useful.

I saw many people answering that ordinary people cannot understand intuitively. Let me explain it simply and clearly: Blockchain is decentralized. When something happens, everyone writes it down and has their own password, which cannot be tampered with.

Even if a hacker wants to change it, he has to do it one by one, which will tire him out. In fact, it is impossible, at least for now.

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms.

Blockchain originated from Bitcoin and is an important concept of Bitcoin. It is essentially a decentralized database. As the underlying technology of Bitcoin, it is a series of cryptographic methods. The associated data blocks are generated. Each data block contains a batch of Bitcoin network transaction information, which is used to verify the validity of its information and generate the next block.

Blockchain has potentially huge application value in financial fields such as international exchange, letters of credit, equity registration and stock exchanges. The application of blockchain technology in the financial industry can eliminate the need for third-party intermediaries and achieve direct point-to-point connection, thereby greatly reducing costs and quickly completing transaction payments.

After reading so many expert advices, I am still confused. I only remember that someone used this so-called "blockchain" to do pyramid schemes in the past...
