1. How to view digital collections as a new trend

Not only the Wu Cultural Museum, digital collections are favored by more and more museums. This trend is especially popular nowadays. violent.

In April this year, under the protection of the Beijing Copyright Certification Center, Crazy Sports and Yuanming Changhe Culture entered the field of digital collections and launched the "Qiankun Digital Collection" digital collection platform. The "Qiankun Digital Collection" platform launched the Old Summer Palace themed series of digital collections - "Old Summer Palace Haiyan Hall Copper Engravings" on April 14, and simultaneously opened reservations for "Old Summer Palace Twelve Groups Summoning Zodiac Beasts (Human Body)" Animal Head) Bronze Statue" digital collection. With the help of advanced blockchain technology, the bronze statues of the twelve zodiac animals in the Old Summer Palace achieved a digital "reunion".

In fact, since March this year, virtual pictures of the twelve animal heads have been successively unveiled at auctions. Information from Alibaba Auction’s official website shows that the limited-edition block chain copyright works of the Twelve Beast Heads of the Old Summer Palace will be sold as early as March 25. The first auction work is a bronze statue of a dragon head. The inventory of each animal head work is limited to 10,000 copies. The copyright can be transferred twice after 90 days, and only one copy will be auctioned at an increased price.

On International Museum Day in May this year, ten major museums at home and abroad, including the Dunhuang Academy and the Louvre Museum, launched for the first time 20 cultural and creative digital collections of cultural relics, covering Dunhuang Supplements, Zizhi Tongjian, World-famous cultural relics such as the Statue of Victory in the Louvre.

28 national first-level museums, including the Hunan Provincial Museum and Henan Museum, also joined forces with the Whale Explorer platform to select 33 national treasure-level cultural relics and rely on digital technology for artistic re-creation. "Traditional culture needs contemporary expression. Without contemporary expression, it can only be called cultural resources. With new product models, it can become cultural IP (intellectual property rights) in the true sense." Duan Xiaoming, Hunan Provincial Bota Youkai Museum, said. Previously, Hunan Provincial Museum Mawangdui and Ant Chain jointly launched four digital collections, each with 8,888 copies. Among them, the three-dimensional collection of dragon patterns was sold out within 28 seconds of going online.

2. Do you know the three important stages in the history of blockchain development?

As blockchain technology matures, blockchain technology has made significant progress in the financial field. results. Whether they are investors, practitioners in related financial fields, or technology practitioners, they are all very concerned about blockchain. Many people or platforms have begun to devote themselves wholeheartedly to it, using blockchain technology to create a new financial system, and have achieved impressive results.

If you have studied blockchain, maybe you have a deeper understanding of blockchain. Since the birth of blockchain, in terms of applications, It has gone through three stages of change. There have been important developments and inventions at every stage of blockchain technology, and blockchain technology has only existed for a small portion of the Internet's time, so there are likely still important developments to come.

First levelSegment technology stage

Bitcoin has been running since 2019. The main technologies supporting the Bitcoin system include hash functions, distributed ledgers, and blocks. Technologies such as chain, asymmetric encryption, and workload proof constitute the initial version of the blockchain.

At present, blockchain technology is not yet mature, the conservative tendency within many organizations is still obvious, and the use of centralized technology and processes in the market to make profits Intermediaries that collect revenue, equipment providers are also hyping up the concerns it may bring.

Second market phase

In early 2013, the price of Bitcoin began rise. In November of the same year, a U.S. Senate hearing clarified the legality of Bitcoin, and the price of Bitcoin rose sharply. But at this time, the blockchain has not yet reached the mainstream social and economic foundation, but its price has risen beyond expectations. At this time, the market opened up the visibility of Bitcoin and blockchain, but despite this, they still did not gain universal acceptance to a certain extent.

The third mainstream stage

Bitcoin, which is an alternative to the mainstream economy, began to recover. Market demand increased and transaction scale expanded rapidly. It also opened up the bull market of 2016-2017. . The enrichment effect of Bitcoin and the spillover effect caused by the congestion of the Bitcoin network have led to the explosive and crazy growth of other virtual currencies and various blockchain applications. At this time, it triggered a crazy global pursuit to make Bitcoin and blockchain a complete global vision.

In 2020, although the epidemic has dealt an important blow to our economy, the hot development of Bitcoin and blockchain tells us that they It is creating opportunities and driving related development. Just like the recent price of Bitcoin is close to 30,000 US dollars, such a market has brought surprises to many people, and it has also promoted the development of exchanges. After all, exchanges are the only way to buy Bitcoins. Its popularity is also It has brought good profits to exchanges, such as Huobi and Saturn Exchange, which have refreshed their historical trading volumes many times due to this bull market. In fact, no matter which industry develops, it will always drive multiple industries. After all, many things are always closely related.

3. Is blockchain a virtual currency?

Regular blockchain companies are not currencies. Blockchain traceability can combat counterfeit and shoddy information.
In the past two years, the word blockchain has been very popular, and blockchain e-commerce will undoubtedly be the biggest trend in the next ten years. However, the industry is full of chaos. Many people think that blockchain is just a currency when they hear it, and they have many misunderstandings about blockchain. So before talking about blockchain, we must first talk about blockschain thought.
Most people now understand blockchain as "coin". There are too many coins in the currency circle, such as Bitcoin and that coin. In fact, blockchain has nothing to do with currency. It is a technology, a business ecosystem, and an idea. It is mainly used in every field. It is very similar to the Internet. Talking about blockchain now is like the Internet 20 years ago. What were we talking about on the Internet twenty years ago? Talking about its technical architecture, operating system, language, server, etc., at that time, people said that Internet e-commerce was a lie because many people had not been exposed to it. In fact, many people feel the same way about blockchain now, especially after being confused by the currency circle, they have a lot of misunderstandings about blockchain.
When did Jiuling Blockchain start? Jiuling started its investigation and preparation in 2016, and it took about half a year to inspect all aspects of the blockchain. In 2017, it began to fully invest in the blockchain field. As of 2020, it is already in its fifth year. It has gained a lot of experience and achieved a lot of results in application. We have never played with coins or conducted an ICO. In the first few years, we didn’t make a lot of noise. We just worked hard to make the technology better, build the platform better, make the browser better, and apply it in terms of traceability. We have done relatively well in the application of traceability since 2017, and many products have been launched. In 2018, more than 10,000 products were applied in traceability. In 2019, we have taken it a step further. This year, we have even gone a step further. In terms of full-process visualization, Get them all open. So at the beginning, we used it in the field of traceability. Since 2018, we have used it in the entire blockchain ecosystem, including blockchain traceability, blockchain invoices, sharing economy, supply chain finance, and universal points. In terms of various applications, as well as the platform technology services we have created, we have fully entered this field, and are relatively mature and fully implemented.
Also, why is blockchain so popular now? Why has the development of blockchain reached the level of "ideology"? This is in line with the development trend of the times.
Let’s review the history of China’s economic development in recent decades. The wealth of the Chiang Kai-shek era was concentrated in the local tyrants, evil gentry and warlords. However, Mao Zedong liberated the majority of the people who were farmers and united the majority of the people, which was more suitable for China's situation at that time. Therefore, he defeated Chiang Kai-shek, overthrew the bureaucracy of the local tyrants, evil gentry and warlords, and put their Wealth was redistributed, productivity was developed again, and revolution and distribution were completely remade. Mao Zedong truly served the people and allowed the people to live a good life. Entering the era of large collectives, people go to work in the countryside to earn work points, and how much food you can get according to the work points you earn. During the Deng Xiaoping era, I felt that this was wrong. It might be because of inefficiency and eating from a big pot. Later, the reform and opening up began. After the reform and opening up, fields were assigned to households according to the number of people. After the distribution to each household, the output increased a lot, and everyone's income was reduced. Passion is stimulated and improvedOutput and improved efficiency. After the reform and opening up, commercial and industrial enterprises began to develop.
It can be seen that economic development is based on the needs of the times. China has been reforming and opening up for decades, and has moved from a traditional economic era to an e-commerce Internet economy. Now that blockchain has emerged, it is also because new problems have arisen in wealth distribution in the Internet era.
In the Internet era, social wealth is highly concentrated on several platforms, such as Alibaba, Tencent, Internet, JD.com, etc. Internet e-commerce leaders have a monopoly on finance, resources, and have too much say in products and other aspects. powerful. Social development has completely lost its balance. The uneven distribution of wealth has made the rich richer and the poor poorer. Those who have no money include the entire industrial enterprises in China. Except for the monopoly central enterprises, most enterprises are now very poor. It is difficult to survive. At this time, another business revolution is needed, and productivity must be redistributed and readjusted. It just so happens that blockchain was born in response to the needs of the times.
The rules and mechanisms of the blockchain are completely open and fair, cannot be tampered with, and are decentralized. It removes the oligarchs of the organization and forms a shared economy for common development. Why does the government support blockchain so much? Because the government can fully enter the blockchain field for supervision, and the privacy of individual citizens can be protected. Personal information on the Internet cannot be protected, but personal information in the blockchain is in your own hands. In the era of Internet e-commerce, oligopoly organizations have monopolized information resources. There are too many fake and shoddy products and too much false information, making it impossible for us to distinguish them.
At this time, the rules and mechanisms for blockchain decentralized supervision came into being. Blockchain is not only a technology (some improvements have been made on the original Internet technology), but more importantly, it is used in applications to solve problems that cannot be solved by the Internet, traditional e-commerce, and traditional ecology, such as traceability. Traceability in the Internet era can be faked. A traceability code can be posted anywhere, but blockchain traceability is different. Blockchain technology is real and everyone can participate together. Through distributed storage, everyone who participates can Everyone can get this data, and then everything can be traced to its source, including products and invoices, including a message sent by a person, which can be traced, stored, and kept true.
Blockchain traceability starts from raw materials, to production and processing, to warehousing, sales, etc. Every link must be fully visualized, with pictures, videos, and text, and every step must be left behind. Traces of links. Only with this kind of mechanism can everyone be completely trusted and be fair, open and transparent in the current situation where there are too many counterfeits and shoddy products and a lack of trust. In short, what blockchain wants to solve are problems that the Internet cannot solve.
Speaking of blockchain, the first thing that many people think of is Bitcoin. Bitcoin's actual contribution to the world is to propose a rule and mechanism. Bitcoin itself has no value, it has no products and no support. But its technology and concept are very good, because this technology cannot be faked, and the source of this technologyThe code is open source and can be shared, and its technology uses the idea of ​​​​blockchain.
The rules and mechanisms of blockchain have been sought after by everyone as soon as they came out. However, in the past few years, they have been confused by currencies. That kind of currency is simply deceptive and goes against the blockchain. Instead, it makes people confused. Everyone no longer trusts the blockchain because they don’t know enough about the blockchain and think that the blockchain is just a currency. Because I want to understand a field, just like Jiuling Blockchain has entered its fifth year, and it is engaged in blockchain ecology, blockchain traceability, blockchain digital points, blockchain technology development, The development of blockchain browsers, etc., are still learning in this field, because it is not easy to learn thoroughly in a field. The reason why we have been very motivated in the past few years is because we know it is a big trend and coming. Just like the Internet 20 years ago, many people didn't believe, didn't understand, and turned a deaf ear. But 10 years ago, big companies like Tencent, Alibaba, and Huawei had emerged. At the same time, this opportunity is now in front of us. Can we seize it? Well, this is a question worth thinking about.
Finally, I want to make it clear to everyone that blockchain has nothing to do with currency at all.
For formal blockchain companies, the government has requirements and certification standards.
Standards: 3 basic requirements (a patent, soft copy, company registration in a national blockchain park, paid-in registered capital, dedicated blockchain R&D funds), 4 implementation application standards (must There are blockchain browsers, websites, blockchain application scenarios, and blockchain products), 5 types of blockchain professionals (blockchain financial professionals, blockchain digital professionals, blockchain credit management Professional talents, blockchain software development professionals, blockchain encryption technology professionals, employees with a bachelor's degree or above who have been employed for more than one year) can receive 6 basic subsidies.
The blockchain industry is a mixed bag. There are at least tens of thousands of cryptocurrency and ICU companies. They all claim that they are formal, but can they produce these certificates? The document states that as long as a company has a digital currency or ICO, it is not a blockchain company.
Under the background of this era, the ideas, rules and mechanisms of blockchain, decentralized supervision, and privacy and confidentiality distribution can protect everyone’s interests, redistribute productive assets, and prevent interests from being too concentrated in certain groups. For oligarchs and institutions, let everyone participate and use their energy to fight against counterfeiting, tax evasion, and false transactions, so as to create an ecosystem that protects the interests of the people, is conscientious, and can provide hematopoietic functions. This is the true purpose of blockchain.

4. What stages has the blockchain developed?

The blockchain has developed in five stages
1. Germination stage: The real germination stage of the blockchain was in 2007 By 2009, a Japanese-American with the pseudonym Satoshi Nakamoto first published a new fantasy report on electronic currency on a cryptography discussion group in 2008 under a different name. Since then, Bitcoin has been born. As early as mid-2007Satoshi began to explore a series of new technologies with the intention of creating a new currency. The Bitcoin white paper was released on October 31, 2008, and the Bitcoin system officially began operation on January 3, 2009.
The main technologies supporting the Bitcoin system include hash functions, distributed ledgers, blockchain, and asymmetric encryption; it can be seen that these technologies build the initial version of the blockchain, which can also be said to be a blockchain It is the underlying technology of Bitcoin. In the three years from 2007 to 2009, Bitcoin was in the experimental stage with the participation of a very small number of people, and real commercial activities had not really begun.
2. "Geek" niche stage: The "Geek" here refers to people who are enthusiastic about Internet technology and who regard technological innovation as their fashion and life. The first Bitcoin exchange appeared on February 6, 2010. On May 22 of the same year, someone bought 2 burgers with 10,000 Bitcoins. On July 17 of the same year, the exchange Mt. Gox was established. This marks As Bitcoin officially flows into the market. Despite this, the only people who can truly understand and enter the market to participate in Bitcoin buying and selling are geeks who are passionate about Internet technology. They discuss Bitcoin technology on forums, mine Bitcoins on their computers, and then buy and sell Bitcoins on Mt. Gox. Today, these geeks have become billionaires.
3. Market brewing stage: At the beginning of 2013, the price of Bitcoin was US$13. However, on March 18 of the same year, the Cyprus government closed banks and the stock market due to the financial crisis, causing the price of Bitcoin to soar. In April, the highest price rose to US$266. . On August 20 of the same year, the German government confirmed the currency status of Bitcoin. On October 14, the Chinese Internet announced the opening of a Bitcoin payment channel. In November, the U.S. Senate hearing also clarified the legality of Bitcoin. On November 19, the price of Bitcoin It rose to $1,242, forming a new high. Despite this, the foundation for blockchain to enter the mainstream social economy is not yet available, and the surge in Bitcoin prices is only due to overly optimistic expectations. The containment of China's banking system, the collapse of Mt.Gox and other events caused the price of Bitcoin to continue to fall. In early 2015, the price of Bitcoin had fallen below 200 US dollars. From 2013 to early 2015, the public began to understand Bitcoin and blockchain.
4. Blockchain mainstream period: Britain left the EU on June 23, 2016, North Korea’s fifth nuclear test in September, Trump’s election in November and other events. The uncertainty of the world’s mainstream economy has led to risk aversion. Functional Bitcoin began to recover. The market demand was large and the increase in transaction volume caused the price of Bitcoin to soar from a maximum of 400 US dollars in 2016 to 20,000 US dollars in 2017. The wealth-making effect of Bitcoin and the transaction overflow caused by the congestion of the Bitcoin network It has led to the explosion of other series of virtual currencies, and various blockchain applications have also exploded. There have been many blockchain assets that are a hundred times, even a thousand times, or ten thousand times, triggering a crazy pursuit around the world, and then Chicago Commodity exchange launches Bitcoin futures trading marks BitcoinOfficially entering the mainstream investment product series, Bitcoin and blockchain have completely entered the global spotlight.
5. Industrial implementation stage: After the market frenzy in 2017, virtual currency and blockchain made adjustments in terms of market, supervision, and cognition in 2018, returning to rationality. Many blockchain projects that imitate blockchain technology in 2017 will gradually die out as the market cools down, and projects with real practical blockchain applications will initially be implemented. 2018 is not only the first year of blockchain, but also a blockchain gold rush period. After the big waves wash away the sand, what remains is relatively good gold.
From the perspective of the history of blockchain development, blockchain technology is not yet mature and is currently in the growth stage. Specific practical applications of blockchain are only used in the financial field. To apply blockchain to other industries, there is still need for There is a journey to go, but the blockchain trend should be grasped. There are advantages and disadvantages in actively learning the new field of blockchain.

5. 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. Simply put, blockchain is 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 the paymentTreasure, 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 change, such as: 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 "Byzantine Universal"Problem" or "Byzantine Fault Tolerance" (BFT). This issue was raised not because of Bitcoin, but because of a special background.

Early aircraft had three independent control systems. Why are three independent control systems needed? ? For example, in an emergency, there is an airplane on the opposite side. 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 is broken, you will be dead. One of the two systems is broken. What should I do? If the good ones say hide, if the bad ones say don’t hide, the computer cannot judge the final result. So three independent systems are needed to support it. The probability of two total bad things is still very small. But this only takes into account the damage. There is malicious intent. What about systems? Are three enough? The answer is no, we need four systems to maintain consensus.

The use of blockchain is also similar, because it has huge node support, 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 Q&A: What is blockchain? What is it used for?

Zone 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 code to produce, verify, store and transmit data. It can also It is said that blockchain is a distributed ledger technology that can provide a decentralized trust mechanism in a non-trust environment, allowing multiple participants to conduct secure and trustworthy transactions without intermediaries.

Block The core advantage of chain technology is decentralization. It can realize point-to-point transactions, coordination and decentralization based on decentralized credit in a distributed system where nodes do not need to trust each other by using data encryption, timestamps, distributed consensus and economic incentives. Collaboration, thus providing solutions to the common problems of high cost, low efficiency and insecure data storage in centralized institutions.

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

Related Q&A: Can you use the easy-to-use Can someone explain to me what blockchain is?

Er Gazi is my childhood friend, and we were naked in Hegou together. Later I came to the city to go to school and work, and lived a life as a drifter in the north; he was at home I farm and do some small business, and now I have two children and a safe life. He envies me for having "seen the big world", and I envy him for his simple life without the pressure of mortgage loans. We have completely different lives that we envy each other??< p>That day, Gazi came to me on WeChat and asked, "What is blockchain?" "I was stunned for a moment. How could this idiot care about such avant-garde words? I pretended to be calm and prepared to talk about the technical principles bit by bit, but I could see that idiot's clouds and fog through the phone screen. Confused expression. How to explain clearly "what is blockchain" to people with a little bit of Internet concept and technical foundation? This seems to be a very difficult problem.??

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

The core essence of blockchain is "decentralization", and almost all operating modes of blockchain revolve around "decentralization" concept to run. 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 fails to pay back the debt, the whole village will know his character, and no one will be willing to have financial transactions 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 felt a little sense of accomplishment and continued: "Of course, the above is just an analogy. In fact, the blockchain does not really allow the villagers to get paper and pen to help you keep accounts, but through the Internet It was completed by networking with the computer."

At this time, Gazi was a little confused and asked: "Then everyone in the village knows what others bought from me, so who would buy from me? Privacy is gone. 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 delaying it?”

“Okay, Gazi, you’ve got the point of asking this question.” It seems that Gazi is not stupid at all, and is still very smart 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 string of numbers and English, and each account has a timestamp to record the time it occurred. , can't be relied on."

Gazi had another question: "Could it be that the people who owe the debt have a good relationship with the villagers, and they join forces to tamper with the records?Where's the account? 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, timestamps, 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 rule, right? "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 helped you keep an account first, and then other people knew about it. Keep accounts, then Li Si will be able to 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 I 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 BitcoinsIt is fixed, etc., 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 it for cash 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. Mining is obviously only a very small number of investors who understand technology can play successfully. I My childhood friend Gazi obviously can’t play with 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 , but there is a huge difference. Ordinary investors cannot determine the value of a virtual currency itself, and 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 Irregularities, theft and hacker attacks often occur, and 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 disagrees with "coin speculation"!

"September 4th" It is illegal to issue virtual currencies

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 use various The packaging and inflammatory rhetoric attract investors into the circle, 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 such asNow we are wearing the cloak of blockchain (picture quoted from the Internet)

And how to identify some MLM activities 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??

6. Blockchain Encyclopedia: The Past and Present of Blockchain - 3.0 Era

< p>The representative of the blockchain 1.0 era is Bitcoin, the representative of the 2.0 era is Ethereum, and the troubled times of various copycats and air coins. Blockchain 3.0 is the era of consumer-level blockchain that has truly entered commercial and physical applications after the troubled times. The typical symbol is the emergence of tokens. The pass has brought about changes in traditional business models and production relations. The pass has moved from the digital world to the real economy and has begun to seek practical applications in various industries.

The pass has three elements, one of which is indispensable.

Pass: The pass can be circulated on a large scale in a network and can be verified anytime and anywhere; Certificate: As a proof of digital rights and interests, the pass must be a certificate of rights and interests that exists in digital form, and it must represent It is a right, an inherent and intrinsic value; value: the token must have economic value.

In this way, the meaning of "token economy" is not difficult to understand. The token economy is a large-scale group collaboration based on tokens. It maximizes the role of tokens, allows every role that creates value to share value fairly, fully mobilizes participation motivation, and forms a self-organizing form.

Major changes in the blockchain 3.0 era

The token economy has laid the theoretical basis and technical support for the large-scale application of blockchain, and the future world will also be transformed by it. Large-scale changes include:

1. Fragmented investment, fragmented income, subverting the traditional way of doing business on the Internet. In the traditional Internet era, it was impossible for ordinary people to participate in the investment of a company, but the emergence of blockchain allows ordinary people to make fragmented investments in a large asset. Assuming that Alibaba originally adopted blockchain for fragmented investment, then all of the originalFragmented shareholders who invested in Alibaba can reap a return on investment that has increased thousands of times today!

2. Break the money-burning model of the Internet and make everyone a winner. The free model of the traditional Internet is essentially to obtain a large number of users through free products to form monopolies and barriers, and then make profits through advertising and value-added services on this basis. In the blockchain 3.0 era, project income is redistributed by issuing tokens to attract more early investors and community users. As the number of users holding tokens increases, the value of the tokens will become higher and higher, and community users, investors, and projects can all benefit from it. In this way, the money-burning model of providing free services in the early days of the traditional Internet can also be improved, and everyone will become a winner.

3. Breaking down the traditional corporate organizational hierarchy, self-organization may become a future trend. In the blockchain 3.0 era, through the establishment of distribution and collaboration mechanisms through smart contracts, it can be more efficient and accurate than enterprises. All token owners will naturally form a community. Everyone has the same goal - "to promote the development of the project and make it a success". They are all members of the community, contribute to the community, promote the value-added of the token, and thus gain benefits together. profit. From a philosophical perspective, this new self-organizing community of freedom, independence, and equality must be the future trend. Gojoy blockchain e-commerce is a blockchain self-organized community. Every consumer is a token owner and a fragmented investor, so he is very happy to co-create and build Gojoy value.

Therefore, we can look forward to the era of great development of the blockchain 3.0 token economy, and the existing ones may be subverted. What we need to be prepared for is to work hard to embrace the blockchain. If you want to seize the trend of blockchain and understand how to transform into blockchain, please leave a message to communicate and we will take you to learn the blockchain professional certification course.

7. What is blockchain

In the simplest terms, blockchain is a distributed ledger.

To understand what this means, we first have to look at its opposite: a centralized ledger. Because blockchain technology started with finance, we will also introduce it below using banks as an example.

The following is our process for using bank debit card transactions:

You can swipe your card to purchase goods in stores.

The merchant sends a statement to your bank for the agreed upon amount.

Your bank will verify that you may have authorized the purchase.

The bank sends the money to the merchant.

Finally, the bank records this information in its ledger.

There’s a lot of technology involved here, but that’s basically it. The last step is important - the bank records all transactions made by the customer. This ledger goes all the way back to the first transaction the bank made.

This ledger is kept, maintained and regulated by the bank. You can read it in your online bank account, but you can't change it. The bank has complete control. If it decides to make a change, there's nothing you can do about it.

Crucially, if hackers were able to access a bank’s ledger, that could cause a lot of problems. They can change the account balance to make it look like certain transactions never occurred, etc.

This is why distributed ledgers are so cool.

Blockchain Network Visualization

If a bank operates on a distributed ledger, each member of the bank will have a copy of the ledger, and whenever any member of the bank When they make a purchase, they tell every other member of the bank.

Each member will validate the transaction and add it to the ledger (the added records are called "blocks"). This has some important benefits, as there is no centralized authority that can manipulate records. Hackers accessing one ledger won't be a big problem because other ledgers can easily verify it.

On the other hand, it requires a lot of work. In short, the second system is blockchain (at least in financial scenarios).

As mentioned above, blockchain is a decentralized list of transactions. If I send Xiao Ming 2 Bitcoins, I send a message to everyone in the network saying "I am sending Xiao Ming 2 Bitcoins" and they all record the transaction.

The future of blockchain, how will it change our lives?

One thing that is important about blockchain is that it is a public resource and no one really owns it because everyone owns it.

Blockchain is not just science fiction. We don’t need to understand the mechanism behind this technology, but you do need to understand that it may completely change our lives in the next 20 years.

This may sound bold, but remember, 20 years ago we were browsing the Internet on Netscape, using state-of-the-art Motorola flip phones, and buying our first DVD players. At that time, if we imagined that a computer could be held in our hands and that we could buy cars, make payments, and watch movies, it would have been considered a fantasy.

Although the impact of blockchain may not be as obvious as the Internet, nor as tangible as mobile phones, blockchain will effectively solve many worries in daily life. Such as intermediaries cheating people, transaction delays, etc. In our current lives, middlemen are everywhere and we take them for granted as a part of life. If one day these intermediaries cease to exist, you will find that the world will become a different place.

Imagine that by 2040, blockchain may become a mature and widely used technology. When one day, you can’t live without the blockchain just like you can’t live without the Internet nowJust like the Internet, you will be surprised to find that this decentralized accounting technology has simplified the complexity and become a part of your lifestyle

8. What is the development history of blockchain applications

p>

The development process of blockchain can be divided into three stages. Melanie Swann, founder of the Blockchain Science Institute, in her book "Blockchain: A New Economic Blueprint and Introduction", divides the application development of blockchain into three stages: Blockchain Chains 1.0, 2.0 and 3.0.

1. Blockchain 1.0 Cryptocurrency Era (2008-2013)

In 2008, Satoshi Nakamoto first proposed the concepts of Bitcoin and blockchain. In January 2009, the first blockchain was launched. At this stage, people are paying more attention to cryptocurrency transactions, and blockchain is only the underlying technology, acting as a "public ledger".

2. Blockchain 2.0 Smart Contract Era (2014-2017)

In 2014, "Blockchain 2.0" became synonymous with decentralized blockchain databases. At this stage, people mainly focus on the application of the platform. Anyone can upload and execute smart contracts on the blockchain, and will automatically receive rewards after execution. Since this transaction process does not require any intermediary, people's privacy is greatly protected.

3. Blockchain 3.0 Large-Scale Application Era (2018-)

At this stage, people began to build a completely decentralized data network. Blockchain technology Applications are no longer limited to the economic field, but have expanded to art, law, real estate, hospitals, human resources and other fields.
