A. How does blockchain technology reflect the relationship between cultural innovation and social practice?

Seven-blockchain technology is a new type of technology, a new type of data computing technology. It can connect cultural innovation and social practice, so that culture can be better reflected in social practice, making the two closer

B. The impact and significance of blockchain technology on society is What

On the morning of November 8, 2019, the 2019 Trusted Blockchain Summit opened in Beijing. Wang Xinzhe, chief economist of the Ministry of Industry and Information Technology, and Shang Bing, chairman of the Internet Society of China, attended the opening ceremony of the summit and delivered speeches.

Wang Xinzhe pointed out that a new round of scientific and technological revolution and industrial transformation characterized by accelerated innovation and integration of information technology is booming. Blockchain technology is important for promoting high-quality economic development, improving national governance systems and The modernization level of governance capabilities is of great significance.

C. What is the role of blockchain technology

Chongqing Jinwowo analyzes the role of blockchain technology: As a distributed accounting electronic ledger, blockchain Make data complete and trustworthy.
Blockchain uses distributed data storage technology to allow all people to participate in the collection, management, and sharing application system to ensure the diversity and integrity of information and achieve the purpose of decentralization.

D. Briefly describe the role of blockchain technology in the development of modern agriculture

Briefly describe the role of blockchain technology in the development of modern agriculture, making agricultural products traceable, Crops have insurance, which directly promotes the connection between production and marketing, makes agricultural transactions more convenient, and makes agricultural finance more efficient. Zaipidian

1. Make agricultural products traceable: The most common use of blockchain in food and agricultural supply chains is to improve traceability. It enables companies to quickly trace unsafe produce to its source and where it was distributed. This prevents disease, saves lives and reduces the cost of product recalls.

E. Blockchain opens the "big copyright era" with value

With the development of the Internet, the digitalization process of the cultural industry is accelerating, and traditional copyright technologyTechnology is no longer able to meet the needs for copyright protection. The industry believes that in order to cope with the copyright protection challenges brought about by digital development, in addition to national policy guidance, the application of new technologies such as blockchain and big data will also play an important role. Recently, Xinhua News Agency China Picture Group stated that it will join hands with the DCI system to build a national imaging copyright service platform that integrates new technologies such as blockchain and digital watermarking.

In fact, in recent years, the country has continuously introduced various policies to support the development of the blockchain industry and encourage the innovative application of blockchain technology.

In 2016, the State Council issued the "Thirteenth Five-Year Plan for National Informatization", which for the first time included blockchain into the category of new technologies and made a cutting-edge layout.

On March 13, 2021, the "Fourteenth Five-Year Plan for National Economic and Social Development of the People's Republic of China and the Outline of Long-term Goals for 2035" was announced, and blockchain was listed as one of the seven digital economies. One of the key industries.

On July 16, 2021, the People's Bank of China released the white paper "Research and Development Progress of China's Digital RMB". Data shows that as of June 30, 2021, there have been more than 1.32 million digital RMB pilot scenarios, covering Living payment, catering services, transportation, shopping consumption, government services and other fields.

Recently, there is constant news about the positive development of the copyright industry and the innovation and development of blockchain technology. First, the China Copyright Protection Center will cooperate with Huawei to build my country's independently innovative DCI (Digital Copyright Identifier, Digital Copyright Unique Identifier) ​​system and create a new ecosystem for the Internet copyright industry based on blockchain technology; second, Xinhua News Agency China Picture Group said , will join hands with the DCI system to jointly explore innovative research in the field of image content copyright in the 5G era, build a national image copyright service platform, and jointly build a new ecosystem for Internet visual copyright transactions.

The "Blockchain Digital Copyright Asset Transaction" channel jointly built and promoted by Alibaba Auction and Xinbian Chain was also launched nationwide recently and started previewing. The Alibaba auction platform is an innovative application of blockchain technology in the digital copyright industry. According to reports, the "Blockchain Digital Copyright Asset Transaction" project provides copyright owners engaged in literature, games, animation, music, art, etc. with the verification and on-chain transactions of digital works based on the "New Version Chain". The copyright of the work generates a unique digital copyright asset certificate in the "New Edition Chain". After the transaction, the legal holder of the copyright asset certificate will have all rights except the signature right of the digital work.

It is worth noting that the national image copyright service platform created this time will use new technologies such as blockchain, image invisible digital watermarks, network-wide image copyright detection, big data, and artificial intelligence. The industry believes that digital watermarking technology can currently be used in commercial applications, including radio and television content monitoring, media asset retrieval, and film and television drama review.The cumulative market size exceeds 2 billion yuan in 8 categories of scenarios, including leak detection and prevention, advertising monitoring statistics, movie projectors, Internet copyright protection, military information confidentiality, and IP product anti-counterfeiting. The absolute advantages of technology and resources are obvious, and the revenue scale of digital watermarking business is expected to expand significantly in the future.

Blockchain naturally solves the ownership confirmation problem in the information storage process based on mathematical principles. The recording, transmission and storage results of copyright information are all effective and credible. Once produced, the information recorded in the blockchain will be permanently recorded and cannot be tampered with. Only by possessing more than 51% of the computing power of the entire network can it be possible to modify the relevant copyright information.

In traditional intellectual property rights protection activities, a series of phenomena such as low execution efficiency of third-party agencies, difficulty in obtaining evidence, high costs, low compensation, and long cycle are common. In the information exchange and interconnection in the blockchain global network, efficiency can be greatly improved without the need for third-party processing. Generally speaking, blockchain solves the problem of being unable to tamper with registration time and content, while digital watermark technology solves the problem of providing evidence.

Relevant personnel of Hanbang Hi-Tech once compared: "I discovered that someone pirated my content and included my watermark. This can provide evidence to prove the problem of piracy and copyright confirmation." Analysis by industry insiders It is pointed out that if watermarks are put on the chain and blockchain + digital watermarks are combined, the core pain points of cumbersome confirmation of rights in the original copyright protection technology can be perfectly solved, and it has high technical value.

Blockchain is closely related to our future. It is an imaginative concept. Many people think that blockchain is only related to digital currency, but actual exposure to blockchain may occur more in: health codes, online ride-hailing, stock trading... In fact, blockchain and its technology Derivative applications can be said to be the hottest emerging industry at the moment.

Blockchain cannot represent the future, but its future has great possibilities. Regarding the application scenarios of blockchain technology in copyright protection, what still needs to be done is to conduct in-depth research on the core technology of blockchain and understand the application nature of blockchain-enabled industries. The application of technology will be in place, the process will be standardized, the information security on the chain will be solved with focus, and it will be truly and effectively implemented in the physical field, so that the future industrial blockchain will usher in a new era of rapid development.

F. How to build smart cities

Smart cities. Currently, smart cities around the world have developed from the concept and model stage to the planning and construction stage, and are still in the exploratory stage. Blockchain is also a hot technology in the exploratory stage, and many people are flocking to it.

Smart cities based on blockchain technology have gradually emerged. In order to meet user needs, the Dashen platform has hired several product managers in the field of smart cities. In order to accelerate the layout in the field of smart cities, in Financial systems, audit systems, supply chains, energy and power, smart park management systems, smart transportation applications and other fields have all made great progress.improvement.

A major role of blockchain is to break data silos. However, previous smart city and smart city management projects still encountered the problem of data islands. It may not be possible to connect smart transportation and smart energy systems made by different companies, but the interconnection of different systems can be achieved on the blockchain, and new applications can be built on the interconnected level and continuously improved in practice. Distributed energy storage technology is the need of the future

Prospects of smart cities based on blockchain

A city is a complex comprehensive system with dense population and various scenarios gathered together. It is destined that building a smart city is a systematic project that requires the help of various existing technologies. Blockchain technology is not a disruptive technology, but it reshapes the trust mechanism based on existing Internet, big data, cloud computing and other technologies, so that the network not only realizes the dissemination of information, but also realizes the transfer of value.

(This question was compiled by Xu Sheng of Dashen Technology)

G. What is blockchain and what is the role of blockchain

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.

In the original English version of the Bitcoin white paper, the word blockchain does not actually appear, but chain of blocks is used. 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, no matter where you go to do errands or Transactions can be completely completed with mobile phones. With the continuous development, everything we do can be easily completed online, including work, production, planting, etc. Of course, no one can do what the rise of 5g brings. An accurate prediction, 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

▪ Identity verification

▪ Equity crowdfunding

The development of the blockchain can be compared to the development of the Internet itself. In the future, there will be an Internet called finance-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 The concept of digital assets (Digital Asset) eventually converges to an intermediate equilibrium point.

The core advantages of the blockchain architecture include:

Any node can createWhen a transaction is established, after a period of confirmation, it can be reasonably confirmed whether the transaction is valid. The blockchain can effectively prevent problems between both parties. 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 may seem 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 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 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, the seller andBuyers 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. 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 people. In this sense, the government must also specify a framework for the development of the blockchain, reconstruct the value of the blockchain, and drive out 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 a completely open life, either to live like a sun or to live like 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 system cannot meet the transaction operation requirements (it is easy toIt is easy to use computer technology to cause your network to be blocked or unable to complete distributed data storage or transactions to be interrupted or delayed at any time. In addition, it is easy to crack the underlying program of the blockchain in terms of the current global computer system (this is The fatal flaw that currently exists in computers around the world is the binary logic of 0 and 1. In addition, it is very easy to crack the blockchain if the inverse blockchain mode operation algorithm is used. This inverse operation mode can also completely tamper with all transaction records. If the real significance of the future Quantum computers are on the market and can directly break all blockchain computer systems in seconds. Bitcoin mining is a Ponzi scheme. 3. Most of the blockchains currently on the global market are basically capital hype concepts to make money.
< br />Blockchain has been mentioned for several years. Early last year, I heard a blockchain boss say that 2018 is the best year for the development of blockchain. After this year, foreign development will fall behind. . What is a blockchain? In terms of impact, it is like pig intestines, connected section by section. Blockchain is to connect these blocks together and fix them, using computer and Internet encryption technology to prevent external Revealing secrets. This technology cannot be explained to non-professionals through professional terms, and generally they cannot understand it. It can only be explained with metaphors. Let me give two examples:

1. A, B, C and D Four people play mahjong in a mahjong parlor for money. They use chips for each game and settle the bill at once when they break up. A loses 1,500 yuan, B loses 300 yuan, C wins 200 and D wins 1,600. As a result, A only has 1,000 yuan. Everyone else has figured it out, but A still owes 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 he says, and he will not write an IOU for this kind of thing. From now on, A What should I do if I don't pay back the money? Except for the four people A, B, C and D present, no one else knows about this. If A wants to default on the debt and says that he doesn't owe the money at all, only three people, B, B, D and D, know that A defaults on the debt, and it is difficult for others to judge A. Whether the money owed will not be repaid. Therefore, the value of the blockchain needs to expand the scope of participation. What if these four people were playing mahjong with a dozen friends watching? The cost of defaulting on the debt would be great, right? This is real life blocks. What about extending to the Internet? Then there are infinite possibilities and there are many scenarios.

2. If four people, A, B, C and D, are doing business in a business group of 500 people, these 500 A group of 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 knew this. , if A does not send money to B within 3 days, then the other 498 business partners in this group will know it. If A defaults on the debt, his reputation in this business circle will be 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 first and the goods would be shipped immediately. C paid 5,000 yuan to A, but A was late. Everyone in the group knows that the shipment is delayed. 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 openly 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 enhance the 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 useThe place is huge.

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...

H. What are the practical effects of blockchain technology

The most widely used application of blockchain is still in the field of financial technology, such as digital asset transactions. As an underlying technology, blockchain is the technical implementation method of Bitcoin. The rapid application of blockchain technology also requires virtual currency. In the past, a large-scale economic scenario that required mutual trust and extensive collaboration among many people could only be solved through a centralized approach, which was very inefficient. The emergence of blockchain technology solved this problem and eliminated this center. An important reason why this center can be removed is that virtual currency provides an endogenous economic incentive mechanism for the blockchain, giving people the motivation to join the economic activities transformed by the blockchain. Of course, blockchain will have more extensive and mature applications in more fields in the future. For example, in November last year, the State Grid submitted a patent application titled "About blockchain power transaction control methods and devices." This year, Xi'an The City Wall International Marathon is also the first in the world to use blockchain technology to register athletes' race data, winning links and other information on the blockchain, using its traceable and non-tamperable technical features to open up information channels between events and effectively Guaranteed the reliability of competition results.

I. What are the functions and characteristics of blockchain

Blockchain is starting a revolution in currency. Blockchain should be liquidity with bit characteristics, rather than currency characteristics.
According to the Radcliffe Report, “Only liquidity is the factor that monetary policy affects the economy."Transmission mechanism", people's spending is not limited by the amount of existing money, but is only related to the amount of money people expect they can get, which may be obtained as income, or by selling assets, or It’s borrowed. The blockchain marks value through tokens, and all assets can be expressed on the blockchain very simply. The structure and marginal cost of asset exchanges tend to be zero. The Technology Research Department of Maoqiu Technology believes that this It is one of the core technologies of the blockchain. What it brings is the explosion of liquidity in a zero marginal cost scenario.
Only liquidity is the transmission mechanism of blockchain value
Currency In layman's terms, liquidity refers to the ability of currency to be quickly converted into cash without loss during circulation. With the intensification of informatization process, currency is required to be more simple and fast in transactions, and the current form of liquidation of banknotes has been far away. Lower than electronic currency.
In the era of Internet finance, "liquidity" can be explained as "the flow of information that transcends the expression of value in the form of banknotes."
We all know that the central bank has left behind the understanding of the value. Control of information flow cannot survive. Because the essence of the central bank's monetary policy is to control the flow of value information, or simply to deny the "information flow". This is also one of the reasons why inflation has increased in recent years.
And electronic currency The reason why its liquidity is gradually stronger than that of banknotes is that before the prosperity of the Internet, the value of banknotes is because it can provide higher value than information flow such as gold and silver. Therefore, the essence of electronic currency is direct value exchange, a formal carrier It is information exchanged by digital signals through the network. This is completely consistent with the characteristics of "liquidity".
Although there was no way to know the situation of blockchain in the last century, based on liquidity analysis, we can still accurately grasp The value characteristics of currency in future generations. Now for blockchain, most people talk about its technical aspects and rarely touch on the value content.
However, if the central banks' "quantitative easing" is blocked by blockchain Once the flow of benefits is traced, technology will immediately "reveal" into benefits.
Is blockchain the general equivalent of distributed, or the specific use value of distributed
Blockchain can record and measure the currency flow facts of transactions in a distributed manner. In the distributed transaction recording system, each node becomes an independent product consumer, and all subjects make equal and decentralized decisions. All transactions are public, and transaction nodes can be anonymous, ensuring the security of node accounts. Decentralized management does not require a central server and avoids expensive operation and maintenance. expenses, reduce costs.
Although blockchain is decentralized in form compared with currency, the liquidity it handles is still based on general equivalents.
We all know that the emergence of blockchain is based on the increasingly serious centralization problem. From the perspective of general equivalent theory, the emergence of general equivalents is because equivalents in the existing value form cannot adapt to the growing exchange needs, so a kind of New equivalents appear to complement existing equivalentsshortcoming.
French biologist Jacques Monod mentioned in "Necessity and Contingency" published in 1970: There is inevitability in the development of things. It is self-evident that the blockchain is designed as a liquidity ledger of general equivalents. Of course, according to Jiang Qiping’s view of “Blockchain and Monetary Philosophy” from the Information Research Center of the Chinese Academy of Social Sciences, blockchain is now just a distributed system designed as a general equivalent. If the characteristics of general equivalents no longer play a leading role in the future, then Future liquidity will need to reflect value in utilization, use, and service applications. Therefore, the Technology Research Department of Maoqiu Technology believes that in the future, blockchain should not only reflect distribution in technology, but should also be reflected in specific value applications.
Heidegger proposed the philosophical concept: Dasein in his masterpiece "Being and Time". There is no better way to describe the blockchain here, that is, God will not be content with being a means of accounting. He wants to live in the present and the purpose of being. This means that if the blockchain wants to develop for a long time, it must develop a function that can be used contextually as a being, rather than a flash in the pan.
If blockchain is no longer a general equivalent, how to view liquidity
From Jiang Qiping’s liquidity point of view, shells, currencies, and blockchain are liquidity in different historical periods and under different value logics. Different carriers. Currency, as liquidity, ignores the use characteristics of value, which are always specific, local, and current, and therefore can only be distributed.
The Technology Research Department of Maoqiu Technology believes that when blockchain captures the distributed characteristics of liquidity, although it will be used as a ledger of general equivalents in the early days, it will eventually have to be modified. Negation of negation develops a valuation function corresponding to services.
