A. Banks are about to be subverted. This popular speech explains clearly what blockchain is.

Blockchain mainly solves the trust and security issues of transactions. Once the information is confirmed and added to the blockchain, it will be stored permanently. Unless more than 51% of the nodes in the system can be controlled at the same time, the modification of the data on a single node cannot be achieved, so the blockchain Data stability and reliability are high. Due to the use of distributed computing and storage, there is no centralized hardware or management organization. The rights and obligations of each node are equal. The data blocks in the system are jointly maintained by nodes with maintenance functions in the entire system. Since the system is open, in addition to the private information of the transaction parties being encrypted, the blockchain data is open to everyone. Anyone can query the blockchain data and develop related applications through the public interface, so the entire system has a high level of information. transparent.
Blockchain is not a single innovative technology, but a combination of many cross-field technologies, including mathematics, cryptography, algorithms and economic models, combined with point-to-point network relationships, and can be established using mathematical foundations The trust effect has become a decentralized system that does not need to be based on mutual trust or a single centralized organization to operate. Bitcoin is the first P2P electronic currency system created using blockchain technology. , used to implement a digital currency system that can be decentralized and ensure transaction security and traceability.

B. How important is blockchain

With its exquisite design concepts and thinking, blockchain can promote the reconstruction of rule systems in economic and social fields and change the relationship between people and The collaborative relationship and benefit distribution mechanism between people and organizations, organizations and organizations; at the same time, blockchain technology can effectively solve the "double spend problem", that is, to prevent the same digital asset from being reused due to improper operations.

This provides a solution to the problem of digital asset rights confirmation and transaction circulation, which can break through the problems such as digital asset rights confirmation and double spending that restrict digital development, and build Forming new production relations that adapt to the development of the digital economy has become the most important value of blockchain technology.

01 Reduce transaction intermediate links and promote cost reduction and efficiency improvement

There are a large number of rent-seeking intermediary organizations in various fields of economic and social life. Some of these organizations do not create real value, but only seek profits through the monopoly of business information or data. , artificially increasing unnecessary transaction links and costs.

Through the innovative application of blockchain, a self-organizing mechanism for economic behavior based on technology can be built to replace the business role of some intermediaries, which can greatly improve data acquisition.It will further open up the upstream and downstream industrial chains, significantly reduce unnecessary intermediary organizations and intermediate links, improve the efficiency of effective docking of supply and demand in various industries, and reduce the burden on the public and commercial entities through the efficiency of acquisition, consensus formation, accounting and reconciliation, and value transfer. Promote cost reduction and efficiency improvement in the real economy.

02 Help confirm the rights of digital assets and stimulate innovation vitality

In the era of digital economy , data resources are becoming more and more important. In 2019, my country has officially regarded data as one of the seven production factors as important as labor, capital, land, knowledge, technology, and management, and has promoted the establishment of a data factor market system.

However, due to the difficulty in confirming data rights, tracing back, and dividing interests, data cannot yet achieve efficient market-oriented allocation and orderly circulation, seriously restricting the development of the digital economy. develop.

Distributed, non-tamperable, traceable, With features such as transparency, multi-party maintenance, and cross-validation, data ownership can be effectively defined, data circulation can be tracked and supervised, and data revenue can be reasonably shared, removing obstacles to the efficient market-oriented allocation of data production factors and other digital assets. It is expected that Reversing the current trend of increasing centralization of data ownership, use and benefit distribution, promote the entire society and digital economy to develop in a more trustworthy, shared, and balanced direction, and further release the innovation vitality of the digital economy.

03 Shortening the distance of trust and expanding the space for collaboration

Modern human lifestyle The changes and progress are all directly related to the development of science and technology. Scientific and technological revolutions always dialectically expand the territory of human activities while shortening the distance between them. Every major technological change is always accompanied by the collapse of "distance" in some sense, thus bringing convenience to people.

For example, the invention of transportation has expanded the radius of human activities and shortened the geographical distance between people; the invention of communication tools has expanded the radius of human "conversation" The physical distance has been shortened; the invention of the Internet has expanded the radius of human access to information and shortened the distance of information; the invention of artificial intelligence has expanded the radius of cognition and shortened the distance of cognition of the world.

Blockchain shortens the distance of trust

Today, blockchain has brought us a new radius expansion. Blockchain can form a crypto-based system without relying on authoritative centers and market environments.The trust mechanism of the code algorithm enables strangers who are thousands of miles away, have never met or even never met to establish a trust relationship, expanding the radius of human trust, thus making it possible for strangers to cooperate.

Especially in some regions and fields with imperfect market mechanisms and lack of credit systems, the value of blockchain technology is even more precious. Blockchain technology enables strangers to establish production relationships based on technical constraints, making it possible to carry out business cooperation in unfamiliar environments, and is expected to inspire a series of new business models.

04 Driving the Internet Revolution and Accelerating Value Delivery

The first 20 years of the 21st century , human society has experienced the comprehensive baptism and reconstruction of the Internet. "Internet +" has brought about earth-shaking changes in related industries and fields. People's lives have become more convenient because of the Internet, economic activities have become more active because of the Internet, and society has become more fair and open because of the Internet. .

However, the Internet mainly solves the problem of dissemination of information. It is difficult to judge the authenticity of information content, and there are still many constraints and obstacles to the transfer of digital assets. While the Internet brings great convenience, it is also filled with more and more false information, and has even become a hotbed for various new types of fraud. While people are becoming more and more dependent on the Internet, they are also increasingly wary of the Internet.

Based on blockchain technology, the next generation of reliable technology based on technical constraints can be built. Trusting the Internet and solving the trust problem of strangers on the traditional Internet will allow digital assets to circulate efficiently on the Internet. Based on blockchain technology, digital assets and intellectual property rights on the Internet can be effectively protected. Asset transactions between people will be as convenient as sending emails. People will put down their guard against the highly dependent Internet because of the innovation of blockchain technology. The Internet will give birth to more valuable applications.

05 Strengthen the constraints of the integrity system and purify the market environment

Blockchain is a Trust the machine. By promoting the deep integration of blockchain and the real economy, a market environment that is convenient, efficient, fair, competitive, stable and transparent can be created. The technical characteristics of blockchain technology that cannot be tampered with and are traceable can play a very important role in the innovation of trust mechanisms in regions and fields with imperfect market mechanisms and incomplete credit systems.

Under the traditional model, market supervision requires a heavy workload and is difficult to implement. Due to insufficient administrative law enforcement resources and regulatory means, it is widely hated by the public. Lao Lai XianThe phenomena of counterfeit goods and fraud are repeated and difficult to eradicate.

Blockchain technology can be formed without the need for intermediaries and laws and regulations. The conditional self-organization and self-supervision mechanism, and the non-tampering, non-repudiation, and non-manipulability of the distributed ledger actually play a role in technical supervision of various economic behaviors.

This will help solve problems such as difficulty in loan financing for small and medium-sized enterprises and difficulties in bank risk control; by recording the entire product production and transaction circulation process, it can significantly reduce the risk of counterfeiting, Various market frauds such as shoddy goods are used to solve problems such as difficulty in market supervision.

C. The development status of the global blockchain industry in 2021 is based on both the global perspective and the domestic perspective

As an emerging information technology, blockchain It will continue to develop in depth in 2021, with continuations and breakthroughs in regulatory policies and applications. Related NFTs, Metaverse, and central bank digital currencies are ushering in an explosion.

In the era of digital economy, it is particularly important to grasp the development and development trends of blockchain. This article will start from two perspectives: a global perspective and a domestic perspective

(1) Global perspective: the blockchain industry is growing in leaps and bounds, and the track in emerging fields is hot

1. Blockchain has become a multinational strategy, and cryptocurrency policies are polarized

2. Blockchain spending grows, with banking industry spending leading

Blockchain and other distributed ledger technologies have shown great potential in improving the efficiency of business operations and creating new ways of delivering value, across industries and Companies are implementing these technologies and integrating them into existing infrastructure and industry plans. According to Statista, global spending on blockchain solutions is expected to reach $6.6 billion in 2021. Forecasts indicate that spending on blockchain solutions will continue to grow in the coming years, reaching nearly $19 billion by 2024

3. NFT, cryptocurrency, and the metaverse are booming

In 2021, new models and new business formats based on blockchain will continue to emerge. Among the hot words of 2021 announced by Collins Dictionary, NFT ranked first on the hot word list, and the words Metaverse and Crypto were also shortlisted for the list.

Starting in March 2021, NFT has experienced explosive growth. The full name of NFTIt is Non-Fungible Token, which is expressed in Chinese as non-fungible token. NFT is a data unit stored on the blockchain. It uses photos, videos, audios and other types of digital files as underlying assets, and supports the verification of the authenticity and uniqueness of the underlying assets.

4. More than 90% of the world’s economies are exploring central bank digital currencies

(2) Domestic perspective: The blockchain industry is making steady progress, and the digital renminbi has achieved gratifying results

1. Promote the development of blockchain technology and rectify virtual currency transactions and "mining" activities

2. The number of registered blockchain companies continues to rise, and the industry is about to enter a "steady recovery period"

3. Digital RMB is in full bloom, and three major challenges need to be overcome

D. Banks are going to be subverted. This popular speech explains clearly what blockchain is

Theoretically, blockchain is It can disrupt banks, but in reality there is still a long way to go.
In layman’s terms, blockchain technology refers to a way for all people to participate in accounting. There is a database behind all systems. You can think of the database as a big ledger. Then who will keep this ledger becomes very important. Currently, whoever owns the system keeps the accounts. Tencent keeps the accounts of WeChat, and Alibaba keeps the accounts of Taobao. But now in the blockchain system, everyone in the system has the opportunity to participate in accounting. If there are any data changes within a certain period of time, everyone in the system can do accounting. The system will judge the person who has the fastest and best accounting during this period, write his recorded content into the ledger, and record this Within a period of time, the contents of the ledger are sent to all other people in the system for backup. In this way, everyone in the system has a complete ledger. In this way, we call it blockchain technology.
Blockchain is just a technology that can be applied to many industries, such as logistics, crowdfunding, law, stocks, and securities. Nasdaq, European Crowdfunding, Walmart, Wanda, Tencent, etc.

E. Explain blockchain in vernacular

img src=' https://p26 . toutiaoimg.com/large/39b 70000088 e 51 B3 c 258 &# 39/

Recently, various ICO financial scams have been blocked in China, but this does not hinder the vigorous development of blockchain technology. After all, technology is innocent and can bring benefits to people. As for how to use it, it depends on people to operate it. If the operation is good, you can recommend development. If the operation is not good, it is like the major ICO projects. Find some knowledge for Internet celebrities to conduct so-called illegal fund-raising and financial fraud.

After talking for a long time, what is blockchain? When it comes to blockchain, the first thing that comes to mind for many people is Bitcoin. We need to solve a problem. Bitcoin is a blockchain, but blockchain is not Bitcoin. in short, blockchain is a distributed ledger technology (DLT), not a token. It has many characteristics, such as decentralization, traceability, and difficulty in tampering.

(1) Blockchain is a distributed database

First of all, this is a decentralized distributed architecture system. Therefore, having only one central server or node is not called a blockchain. For example, if you go to Taobao to buy a mobile phone, you and the seller are strangers and have no basis for trust. If you give the money to the seller first, the seller may block you by not delivering the goods, and then your mobile phone money will be gone. If the seller ships first, do you pay? It is possible that you do not pay the seller after receiving the goods, and one party may lose money anyway. At this time, a third-party guarantee is needed to solve the trust problem. Just like Alipay now, you give money to Alipay and the seller will deliver the goods. When you receive the goods, the seller will receive the money.

The above example is a centralized system because all guarantee work is handled by Bora, a third-party payment company. Suppose one day Alipay wants to tamper with data, neither buyers nor sellers can do anything because all authority is in the hands of one company.

At this time, a distributed database is needed. This third party is no longer Alipay, but thousands of monitors. When you buy a mobile phone on Taobao, you will shout to everyone that I am going to XXX to buy a mobile phone, and I paid XXX yuan. The other person will yell like everyone else. I collected XXX’s mobile phone bill and sent it over. In this way, everyone knows about this transaction and everyone is recording this transaction, so it is useless if one or two nodes have problems or malicious behavior, because most nodes have recorded this matter.

(B) Blockchain uses encryption technology to ensure data security

There are two important points here: 1. Crypto-enabled hash function 2. Asymmetric encryption.

If you are interested in specific concepts, you can go online, but people without basic knowledge may not be able to understand it, because these two points are too professional. In fact, if you only know the use of blockchain, you don’t need to have an in-depth understanding of it. It is also a technical concept. All you need to know is that blockchain relies on these technical points to ensure data security and is not easily tampered with. Of course, many people say that these two points can guarantee 100% non-tampering. I want to be a little conservative here. As an author who works in the security industry, I have always been skeptical about 100% security, so it may be more appropriate to call it difficult to be tampered with.

I will briefly introduce these two concepts and try to explain them clearly in plain English.

1. Cryptographic Hash Function

This is mainly used to verify the integrity of information. For example, I sent a message to the company leader saying that I was sick on Friday and needed to take a day off. At this time, a hash value will be generated based on the message I sent, such as: 123456. At this point, when the leader receives this message, a hash value is also generated. Because the content of the message I sent has not changed (it has not been tampered with), the hash value remains unchanged, still: 123456. This is if someone wants to tamper with this news and get sick on Friday and need to take a year off. At this time the hash value will occurChange, for example: 123489. That's when we learned our information had been tampered with.

2. Asymmetric encryption

It is mainly used for information encryption and authentication. It is actually two keys, one is called the public key and the other is called the private key. Public key encryption, private key decryption.

A public key is a key that everyone has. You own it, I own it. We can all encrypt with this key, but when decrypting it must be decrypted with my private key. If you don't have my private key, you can't decrypt it.

(C) The blockchain uses a consensus algorithm to reach consensus on new data.

The role of the consensus algorithm is to enable all nodes to reach a consensus on the new block. In other words, everyone must approve the new block.

For a centralized deployment system, this is simple, everything is controlled by the center, but in the distributed system of the blockchain, it is very complicated. For example, there are three nodes. A said he bought a mobile phone from XXX store and paid for it, B said he didn’t pay, and C said he didn’t pay enough. Then who do you listen to? What's more, blockchain technology is not as simple as three nodes, but a huge distributed system.

This is when a solution is needed. There is a corresponding problem in computer science called the "Byzantine Universal Problem" or "Byzantine Fault Tolerance" (BFT). This question was raised not because of Bitcoin, but because of a special background.

Early aircraft had three independent control systems. Why do we need three independent control systems? For example, in an emergency, there is a plane opposite. How to judge whether you should hide? If there is only one system, there is no choice, which is equivalent to centralized deployment. If the system breaks, you're dead. What if one of the two systems breaks? The good ones are said to hide, and the bad ones are said not to hide. The computer cannot judge the final result. Therefore, three independent systems are needed to support it, and the probability of two total failures is still very small. But this only takes into account injuries. What should I do if there is a malicious system? Is three enough? The answer is no, we need four systems to maintain consensus.

The use of blockchain is similar, because it is supported by a huge number of nodes, and each node is an independent system without interfering with each other. We can assume that the number of failed nodes and malicious nodes is limited, so it will not cause abnormal consistency of data.

Related questions and answers: What is blockchain? What is the use?

Blockchain is a new computing paradigm and distributed infrastructure that uses fast chain data structures, distributed node consensus algorithms, cryptography and smart contracts based on automated script codes to produce, verify, store and transmit data. It can also be said that blockchain is a distributed ledger technology that can provide a decentralized trust mechanism in a non-trust environment, allowing multi-party participants to conduct secure and trust-based transactions without intermediaries.

The core advantage of blockchain technology is decentralization. It can realize decentralized credit-based transactions in a distributed system where nodes do not need to trust each other by using data encryption, timestamps, distributed consensus and economic incentives. Peer-to-peer transactions, coordination and collaboration, thereby solving the common high costs, inefficiencies and data storage concerns of centralized institutions.The congruence problem provides a solution.

The fields of use of blockchain include digital currency, certificates, finance, anti-counterfeiting and traceability, privacy protection, supply chain, entertainment, etc. With the popularity of blockchain and Bitcoin, many related top domain names have been registered. It has had a relatively large impact on the domain name industry.

Related Q&A: Can you explain to me what a blockchain is in an easy-to-understand way?

Er Gazi is my friend since we were young, and we were naked in Hegou together. Later, I came to the city to study and work, and lived a life as a drifter in the north; he farmed at home and did some small business, and now he has a son and a daughter, and his life is safe. He envied my so-called "seen the world", and I envied his simple life without the pressure of mortgage loans. We have completely different and mutually enviable lives??

That day, Gazi came to me on WeChat and asked "District" What is a blockchain?" I was stunned for a moment, how could this idiot care about such an avant-garde word? I pretended to be calm and prepared to talk about the technical principles bit by bit, but I could see the confused expression of that idiot through the screen of my mobile phone. How to explain "what is blockchain" to people who have a little bit of Internet concepts and technical foundation? This seems to be a very thorny problem??

The village commissary interprets the core of blockchain (picture quoted from the Internet)

The core essence of blockchain is "decentralization", and almost all operating modes of blockchain operate around the concept of "decentralization". Once you understand what "decentralization" is, you can basically explain the question "what is a blockchain?" For Erga, of course, he must perform a version that he can understand.

“I said, Gazi, are you still open that canteen at the east end of the village?” Gazi answered yes. I decided to use this canteen as an example to explain the actual use of blockchain in modern business and financial models. Scenario, so that he can better understand what blockchain is.

"Are there still many villagers who take credit now? By the end of the year, some of the accounts cannot be remembered clearly, and there are still many defaulters or those who refuse to accept their accounts?" At this point, Ergazi got emotional and kept complaining. Nowadays, people's hearts are not as old as before, and business is difficult to do!

"In the past, the operation model of your canteen was a typical centralized one. You granted credit to the villagers and allowed them to take accounts on credit. All accounting was done directly through you and our villagers. You were the center of all accounting affairs." Ergazi said I understand, let me continue.

I said: "If you fail one day, then all the accounts will become dead debts? It will be difficult to get back the IOUs written in black and white, let alone those who remember the accounts verbally, but the block The decentralization of the chain can solve this problem very well. As long as the earth still exists, the blockchain will remember that every account will exist forever." Erga became more energetic after hearing this.

The essence of blockchain is “decentralization”

“The essence of blockchain is decentralization. Once someone takes credit from you, all the neighbors in the village will help you keep accounts. Because of the accounting There are many nodes, and it is neither easy to make mistakes nor others to default on the debt, so everyone reaches a consensus. If someone maliciously refuses to pay back the debt, the whole village will know his character, so that everyone can reach a consensus.No one is willing to have any financial dealings with him in the future??"

At this point, Gazi was obviously a little excited. It seemed that he was really worried about the credit issue. Seeing that Gazi was interested, I He also had a small sense of accomplishment and continued: "Of course, the above is just an analogy. In fact, the blockchain does not really require the villagers to get paper and pen to help you keep accounts, but is completed through the Internet and computer networking. "

At this time, Gazi was a little confused and asked: "Then what others bought from me, wouldn't everyone in the village know it? Then who would buy things from me? There is really no privacy at all. And you don’t have time to keep accounts here. Last year’s accounts are said to be this year’s. What if you keep procrastinating? "

"Okay, Gazi, your question is on point. "It seems that Gazi is not stupid at all, and he is very shrewd in doing business. I continued to explain: "So, the recording and transmission of this information are all done through encryption. What you see is a picture of numbers and English. String, and each account has a timestamp to record the time of occurrence, which cannot be relied on. "

Gazi had another question: "Is it possible that the people who owe the debt have a good relationship with the villagers, and they join forces to tamper with the accounting? Then you won’t be able to explain clearly at that time??”

“Gazi, that’s all you have, haha. "I understood Gazi's concerns and continued to explain: "The mechanism of the blockchain requires more than 51% of people to agree to tamper with a bill. Everyone has a degree of closeness and distance between them, and it is impossible for everyone to favor the same person. If it were a computer, more than half of the computers on the entire network would need to recalculate. This project would be so huge that it would be almost impossible to complete??"

In this way, through the actual situation of the canteen and combined with some scenes in life, Gazi understood What is in the blockchain: decentralization, distributed accounting, consensus mechanism, encryption mechanism, timestamp, and the characteristics of being difficult to tamper with.

Ergazi was silent for a moment, seeming to be digesting the example I just gave him. I don’t know how much he can understand the example. Not long after, he sent me a voice message on WeChat: “What does blockchain mean? In the past, when I bought goods online and paid, I had to go through Jack Ma’s house. If there is a blockchain, can we directly trade with the seller? Anyway, the accounting is very safe. "

"Okay, Gazi, it's really clear at first glance. Blockchain is essentially a decentralized distributed ledger data cloud. Of course, it can be understood according to your understanding. "I'm very happy that Gazi can roughly appreciate the true charm of the blockchain. Fortunately, my words have not been in vain.

What is Bitcoin? (Picture quoted from the Internet)

"Then Bitcoin What is this thing again? What does it have to do with blockchain? "Gazi asked.

I thought about it briefly and decided to continue to explain to Gazi with the story of the canteen: "In your canteen, the villagers can't keep accounts for you for free all day long. Do you have to carry some during the holidays? This is the reward mechanism of the blockchain, and everyone who participates in bookkeeping may receive rewards. "

"Then what are the rewards based on? There has to be a ruleThen? "Gazi asked very puzzled.

I explained: "Zhang San went to your store to borrow a pack of cigarettes on credit, but Li Si knew about it first and kept an account for you first, and then others knew about it. Keep accounts, then Li Si can get a small red flower as a reward ~ This small red flower is generated by the blockchain system and has no value in itself, so you do not need to pay any cost for this small red flower??"< p>“Can Bitcoin be spent as money? How is it different from the banknotes we usually spend? "Gazi continued to ask.

"Bitcoin is a digital encrypted virtual currency. In principle, it has no value itself like our banknotes. However, banknotes have a credit guarantee from the state, so they have value. Bitcoin is the value formed by consensus among Bitcoin network users, and it has tradable properties, so it can be used to carry value. "What is said here is a bit profound. I don't know if Gazi can understand it.

I continued to explain: "Banknotes can be printed infinitely. If more are printed, inflation will occur. When we were young, popsicles worth 1 cent were very good. , now you can’t eat with 1 yuan. Of course, there are many factors that affect inflation. The number of Bitcoins is fixed, and there is no possibility of unlimited over-issuance. However, different people have different judgments on their value, and coupled with the influence of supply and demand and investor sentiment, their prices are always fluctuating. ”

What is the difference between Bitcoin price fluctuations and stocks?

“So is speculating in Bitcoin just like speculating in stocks? Can you understand it this way? "Gazi seems to know a lot.

"In fact, there are some similarities, but there are also big differences. "I continued Gazi's topic: "The price of stocks always fluctuates around the valuation of companies, and there is government supervision in the stock market. Bitcoin itself has no value. It is priced entirely based on supply and demand and player valuations. It grows wildly without any government supervision. Therefore, it may have higher risks and higher returns than stocks. "

In the end, Gazi revealed the real purpose of today. He asked me: "Can I invest in blockchain projects? ”

Gazi is a typical example of those who don’t go to the Three Treasures Hall for anything. Although there is a large circle of people who are involved in both blockchain and Bitcoin, in fact, what he really cares about is “blockchain project investment” Is it reliable? "When these words came out, I was extremely shocked. Now the so-called blockchain investment projects have actually reached fourth- and sixth-tier cities and small towns!

As of now, there are only three types of blockchain investments. Situation: Mining, currency speculation, so-called blockchain projects.

Mining and currency speculation are still the main lines of the blockchain (pictures quoted from the Internet)

The so-called mining means mining by purchasing mining machines, etc. Equipment, mine virtual currency, and then sell and realize it to get returns. You can install the mining machine yourself, or you can find a mining pool to host it, but the core keys to profitability are "computing power" and "power consumption" as well as Investment in equipment. With the sharp drop in the price of virtual currencies and the increase in mining difficulty, the current mining returns of many currencies are very unsatisfactory. And mining is obviously very rare.Only investors who understand technology can play it successfully. My childhood friend Gazi obviously cannot play it.

As for "coin speculation", I have just introduced some differences between Bitcoin and stocks in the previous section. In principle, although they are both "buy low and sell high" operations, they are very different. Ordinary investors cannot determine the value of a virtual currency itself. The price is determined entirely by the relationship between supply and demand, which is somewhat similar to what we often call "market makers." On the other hand, the virtual currency trading market is extremely unstandardized, and fraud and hacker attacks often occur. The risk factor is much greater than investing in stocks. For the safety of my friends' funds, I am one of the ten thousand people who disagree with me and come to "speculate in coins"!

The "September Fourth Movement" stipulated that the issuance of virtual currencies is illegal

In fact, in my opinion, most of the so-called investment projects in the market are essentially "illegal fund-raising" and "pyramid schemes." Some so-called blockchain investment projects attract investors into the circle through various packaging and inflammatory rhetoric, and then create the illusion of profitability by building a software and hardware ecosystem of issuing new coins + mining + currency speculation, and then finally run away. Our country's laws clearly stipulate that the issuance of virtual currencies is illegal.

Illegal pyramid schemes now wear the cloak of blockchain (picture quoted from the Internet)

And how to identify some pyramid schemes under the guise of blockchain? In fact, these pyramid schemes are also so-called Ponzi schemes, what we people often call "empty gloves." These so-called "direct sales" or "marketing" activities often have no actual products to circulate, and rely more on developing "downline" to ensure top-level profits. With the rise of the concept of blockchain, this MLM model has shown an intensification trend, and it even deceives people under the banner of state support for new technologies.

When Gazi asked, “Can blockchain projects be invested in?”, I realized the seriousness of the problem. Gazi is a typical young man from a small town, and his pursuit is his wife and children. But when faced with the attraction of "wealth", people often do inappropriate things. Mining and currency speculation are simply not suitable for him, let alone blockchain investment projects that are most likely "illegal financing" or "illegal pyramid schemes"!

I quickly called Gazi and conducted the above analysis carefully??

F. The bank is going to be subverted. This popular speech clearly explains what the blockchain is

p>

The word "subversion" is an unscrupulous and eye-catching description by the media. The correct attitude is that blockchain will help the banking industry improve safety and efficiency.
Traditional banks use centralized ledgers, and regulators have a general ledger in their hands. We need to use a sum of funds, and the general ledger records information about changes in funds. If the general ledger server is hacked, or if someone internally has enough power to modify the ledger, our deposit data will be wrong. This is why some customers have lost their deposits.
Blockchain is a distributed ledger. On the blockchain, the ledger is synchronously stored on nodes around the world. If it needs to be modified, the technical rules of the blockchain force that more than 51% of the server nodes in the world must be modified. And this principleIn theory it is feasible, but in fact it is not feasible.
Banks close their doors at 16:30 every afternoon. One of the things they have to do is to centralize and exchange transaction data among banks. With blockchain, this link is eliminated. Direct peer-to-peer real-time exchange.
When you go to the bank to open an account and do business, the information is provided again and again. If the user uploads business and personal information to the blockchain, a QR code can download the user information, and it is safer and more secure. Accurate, saving a lot of trouble, greatly improving safety and efficiency...

G. The innovative application scenarios of blockchain in the digital economy era continue to expand

In the era of digital economy, blockchain, as a new driving force for economic growth, is leading a new round of global technological revolution and industrial transformation. At present, blockchain is developing rapidly and penetrating into all areas of our country's economy, which not only strengthens the resource allocation capabilities of the digital economy, but is also of great significance for promoting high-quality economic development and improving the modernization of the national governance system and governance capabilities.

Blockchain is the new engine driving digital development

As the role of blockchain in the digital economy grows, its innovative applications continue to expand. According to the "China Mobile Internet Development Report (2021)", "There were nearly 2,000 blockchain projects across the country last year, and the blockchain market size exceeded 3.2 billion yuan."

China Academy of Information and Communications Technology Industrial Internet and Liu Yang, deputy chief engineer of the Internet of Things Research Institute, once said that blockchain is a trust infrastructure necessary for the development of economic activities. It provides inclusive public services for finance, agriculture, industry, energy and other industries and the public. It is also a Collaboration tools, transforming production relations, and integrating with the real economy will improve collaboration efficiency and reduce costs.

In fact, blockchain is called "the next generation of Internet-level technology" because of its disruptive innovation, and is considered the most revolutionary among strategic emerging technologies. In October 2019, blockchain was elevated to a national strategic level. In April 2020, blockchain was included in the new infrastructure and was listed as one of the seven "key digital economy industries" in the "14th Five-Year Plan". In the future, blockchain will usher in new opportunities for innovation and development.

However, Zhang Chao said that currently, data governance on the blockchain is still a huge challenge at a global level. First, data governance requires a clear regulatory subject, but in blockchains or distributed ledgers (or public chains) other than alliance chains, a relatively clear object may not be found as a regulatory subject; secondly, due to the The data on the chain cannot be easily tampered with, which means that during the data governance process, the rights of the data owner to modify and delete the data may not be fully protected.

Blockchain innovative application scenarios continue to expand

Driven by favorable policies and market demand, blockchain innovative application scenarios continue to expand. In recent years, in addition to the two major outbreak scenarios of finance and government affairs, there is even more promise in empowering the field of rule of law. On the one hand, the multi-faceted and multi-field application of "blockchain + rule of law" can effectively improve the efficiency of rule of law construction; on the other hand, blockchain technology can also help public prosecutors and law enforcement agencies crack new criminal cases.

Industry insiders believe that based on the analysis and tracking of massive on-chain data, blockchain technology provides governments, enterprises and users with on-chain data monitoring, transaction maps and on-chain address analysis. For suspected criminal activities such as virtual currency, the blockchain browser provides on-chain data tracking to combat virtual currency crimes, maintain national financial security, and provide "blockchain power" for the construction of Digital China.

H. What the blockchain changes is not productivity, but production relations. The capital economy will be subverted by the token economy!

"Lichang" - the first community for public chain mining

What the blockchain brings is a once-in-500-year opportunity, because it does not change productivity. But the relations of production.

1. Another economic form will be reborn

If a person works for a company 8 hours a day, must he work for a company in the future? Is it possible to be self-centered rather than company-centered?

This is the thinking brought to us by blockchain technology.

Most people think of blockchain as a new technology, some say it is a new generation of the Internet, and some call it the digitization of currency or assets. The author believes that what blockchain is facing is to subvert the entire social relations and social organization forms. It is a manifestation of the development of productivity to a certain stage. The Internet has brought about a great development of productivity. The previous production relations have no longer adapted to the development of productivity levels, and have even hindered the development of productivity.

The exchange of new productive forces and the birth of new production relations are the token economy brought about by blockchain technology. It has a far-reaching impact than the blockchain technology itself.

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

The capital economy will be subverted by the token economy, and capitalism may be subverted by tokenism.

2. Reshaping human organizational forms and business organizations

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

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

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

The organizational form of resources has changed: funds are no longer the most important, resources are the most important.

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

3. Everyone is a contributor and at the same time a recipient

What has always been the case is that employees in a company get a salary, and executives get rewards plus some options. , the channel dealer earns a product price difference, and the partner earns a service fee. Now this logic has changed, and the source of value has been changed. In the past, the surplus value of labor was deprived of capital. In the future, everyone should be a contributor and everyone will enjoy it.

A person has a variety of resources: human resources, knowledge resources, and governance resources. Everything is centered on the individual, not around the product or the company.

Blockchain subverts the company's core value - maximizing shareholders' interests, and also subverts the company itself. Blockchain's transformation of traditional companies is reflected in its fragmentation of production processes and data, which is exactly the opposite of many social organizations. In the past, in industrialized societies, business could only be done on a large scale because transaction costs were very high.

Blockchain makes granular transactions possible, miniaturized and trustworthy. In the original exchange of capital flows, there must be a process of fund payment when signing a contract. After digital assetization, it can be automatically processed through smart contracts, and the company system faces various challenges.

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

4. What changes is not productivity, it changes production relations

The token system is a great invention. It is not a technology or a currency for financing, but the integration of all New organizational forms and operating methods for resource and value sharing are the next economic era. The "certificate circle" will become a more sustainable circle with the influx of more traditional companies after the "coin circle", "chain circle" and "mining circle".

Tokenized transformation: currency reform → chain reform → certificate reform

1C0 is the blood, the chain is the skeleton, and the token is the soul. It can make a person and a community come alive. Everyone is a creator and value contributor, and everyone is an owner and enjoyer. This is the real meaning. However, the current currency reform and chain reform claim to be decentralized and cannot be tampered with, but they still remain at the technical level.

Technology will develop very fast in the future. This is not a problem that needs to be worried about. The biggest problem is whether the production relations have been adjusted. Just like as long as the company is established, financing and share reform are not problems.

The upper layer of the pass is currency reform, financing, 1C0, and white paper, which has the function of financing and financial attributes; the lower layer is chain reform, blockchain technology, distributed accounting, encryption authorization, and consensus Mechanisms, smart contracts, etc. have technical attributes. They are interrelated and form a business logic, which is the core of the certificate. But now the top and bottom are separated. People who talk about chains talk about chains, and people who talk about coins talk about coins.

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

Therefore, in the future society may enter a token community organization, a token economy, or even a tokenism society.

Which fields or companies need token reform

5. Tokens create value and issue coins through the blockchain

The value of the currency is stable , the certificate can appreciate in value. Therefore, the transformation of the token system is a precise distribution and transaction model.

The certificates obtained by investors, the certificates obtained by producers, the certificates obtained by allocators, the certificates obtained by traders, and the certificates obtained by consumers. Balancing these five relationships requires accurate big data analysis. , to achieve a balanced and stable growth mechanism. Therefore, securities reform is not that simple. Chain reform involves the participation of technology.Reform means making a white paper, and certification reform can create core value.

After centralization, the company is at the core, while decentralization is at the core of the token. A completely decentralized company has no value.

Is the value of a fully centralized token zero? Does the issuance of coins mean the embodiment of real tokens?

In the future, many company forms will change. Public companies, private companies, credit companies, market capitalization companies, and market capitalization management price-to-earnings ratios are actually issues we need to think about during the transformation of the token system.

In the past, opportunities were once in 10 years, once in 30 years, and once in 100 years. Now they are once in 500 years. The author believes that blockchain is a very big opportunity. Instead of participating in the currency circle , chain circle, it is better to create enterprises with real blockchain token value.
