A. In what fields is blockchain suitable for application?
The first one is the information security industry.
The second one is the bill business field
The third one is the payment and settlement business.
Fourth, identity/account authentication business.
Fifth, each node participating in the maintenance of the equity proof blockchain can obtain a complete data record. Using the characteristics of reliable and collective maintenance of the blockchain, the rights of the owners of equity can be confirmed.
Blockchain technology is really powerful. With the advancement of the times, this technology may change the development direction and trend of the financial industry, and because the blockchain technology itself has large capacity, high-speed computing, security, and convenience And other characteristics have laid a strong foundation for the advancement and popularization of technology.
B. How to apply blockchain technology to Internet financial companies
Blockchain is a distributed point-to-point structure that is decentralized, open and transparent, highly secure, and reliable. With advantages such as strong traceability, it is an effective technology that completely solves issues such as trust, efficiency, and trade. Therefore, blockchain technology is most likely to bring about changes in the financial field, such as exchange clearing, cross-border payments, inter-bank clearing, etc. At the same time, blockchain technology can also help solve many collaborative problems in the real economy, such as logistics and supply chain. For example, for insurance companies, blockchain can prevent insurance fraud and solve "qualitative management problems", and the promotion of smart contracts can help improve user experience.
However, it is still in the experimental stage, but capital has quickly followed up on the layout. According to the "In-depth Analysis Report on Business Model Innovation and Investment Opportunities in China's Blockchain Industry" released by the Qianzhan Industry Research Institute, between 2012 and 2015, the amount of venture capital investment in the blockchain field increased more than 200 times, from US$2 million to 469 million US dollars, with approximately 205 venture capital institutions around the world participating in investment.
However, although the development of blockchain continues to be popular, it is still far from large-scale application. At least it faces problems at multiple levels such as technology, application, and security. More importantly, government supervision has not followed up, and relevant companies have to consider policy risks.
C. 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 did not actually appear bloThe word ckchain is used instead of chain of blocks. 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). They all express the same concept - digital assets (Digital Asset). Ultimately Convergence to an intermediate equilibrium point.
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 distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithmand other new application models of computer technology. 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 a wide range of applicationsscene. The future technological competition will also be a 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 matchThe prescription often becomes 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 his debt, it is basicallyNo money is owed, and only three people, B, B, and D, know that A has defaulted on his debt. 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.
In the future, in addition to using technologies such as side chains, lightning networks, and cross-chains, blockchain will also need 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 waste of resources.
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 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...
D. Is blockchain technology really going to be a post-Internet era? What is its manifestation?
Yes. In essence, it is a shared database, and the data or information stored in it is "unforgeable" and "leaves traces throughout the process"“ Features such as "traceability", "openness and transparency" and "collective maintenance". Based on these features, blockchain technology has laid a solid foundation of "trust", created a reliable "cooperation" mechanism, and has broad application prospects. p>
The foundation of blockchain technology is open source. In addition to the private information of the transaction parties being encrypted, the data of the blockchain is open to everyone. Anyone can query the blockchain data and develop through the public interface. Related applications, so the entire system information is highly transparent. As long as you cannot control 51% of all data nodes, you cannot arbitrarily manipulate and modify network data. This makes the blockchain itself relatively safe and avoids subjective and artificial data changes. Blockchain The technology does not rely on additional third-party management agencies or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes information self-verification, transmission and management through distributed accounting and storage.
E. What are the differences between blockchain and the Internet
Blockchain is essentially a decentralized ledger system that is decentralized, open, information cannot be tampered with, and is programmable. Characteristics, it can be used as the underlying storage and transmission protocol of the Internet of Value. Blockchain is expected to lead us from personal trust and institutional trust to the era of machine trust. The consensus mechanism is the core of regional chain construction. Digital currency is just the beginning, and blockchain can More changes can reshape the world's trust system and solve many problems in the past where the cost of trust was too high.
As an analogy between blockchain and the Internet, they have one core difference: the underlying protocol and upper layer of the blockchain and the Internet The value of the application is completely reversed. Mainly due to the two core characteristics of the blockchain:
The first characteristic is that zero-knowledge proof causes a change in data ownership. In other words, the blockchain The personal data of users on the Internet belongs to the user and does not need to be provided to the application party and stored on the central server. Then Internet application layer services, such as BAT, the core supporting "data" behind the market value, have lost their original role in the blockchain field. Value.
Another feature is the economic incentive model brought by tokens, which gives extremely high value to the underlying protocol. In the Internet era, no one paid for the http protocol, no one paid for sending and receiving emails, and no one paid for sending and receiving emails. People pay for Google’s search services.
F. What does blockchain mean and what are its main uses
In recent years, a hot word has appeared frequently on the Internet, that is, "blockchain" "Blockchain", this word gives people a very noble and powerful feeling, but many people don't know what blockchain means? And what are the main uses of blockchain? Let's take a look at the relevant content that has been issued .
Blockchain Blockchain is actually equivalent to a disintermediated database, which is composed of a series of data blocks. Each of itsA data block contains information about a Bitcoin network transaction, and these are used to verify the validity of the information and generate the next block. In other words, blockchain is essentially a decentralized database.
In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and uses cryptography to Guaranteed immutable and unforgeable distributed ledger. Broadly speaking, blockchain is actually a distributed infrastructure and computing method that is used to ensure the security of data transmission and access.
In addition, the blockchain is composed of six infrastructures: data layer, network layer, consensus layer, incentive layer, contract layer and application layer. Regarding its role, blockchain is mainly used to solve the trust and security issues of transactions. The above is the relevant content about the meaning and function of blockchain. I hope it can help friends in need.
G. How extensive is the scope of blockchain?
The breadth of blockchain is just like the Internet. The future trend is increasingly towards blockchain. To be honest, there are many Some binance chains, Binance Smart chains, etc. are practical applications of blockchain.
