From today, the word "token" will be officially recorded in the history of blockchain. Its impact on the economy is no less than the impact of printing on society. It's a showdown between typography and knotted journaling!
On January 21,
The big names who came to share include:
Yuan Dao Founder & Chairman of 21Vianet Data Center, Chairman of Zhongguancun Blockchain Alliance
Jiang Tao Founder & Chairman of CSDN
Meng Yan Vice President of CSDN
Yu Hao Founder & CEO of Xunda Cloud
Wang Wei Founder of Beijing Zhiding Technology
Cai Yi Technical Director of Beijing Zhiding Technology
Feng Lu Senior Education Industry Expert
To say that the biggest highlight of this salon is the "token". It began to be clearly stated by the industry leaders of the blockchain, and the value highlighted behind the word "token" began to be truly spread. From now on, this group of tech geeks will have their own independent beliefs and ideals under the birth of the blockchain.
As the founder & chairman of CSDN, the largest IT community in China, Jiang Tao also came to the scene to share with everyone his profound experience of the new generation of technology booms such as blockchain.

In Jiang Tao's view, blockchain is not only a technology, but also represents a right confirmation, an asset, and a financial means. In this regard, he used an example to illustrate the huge impact and transformation of the production system of the blockchain. He mentioned that there were originally more than 3,000 people, but they were not very active. Only a community of 10 or 20 people actually worked. Since the announcement of the ICO, everyone has begun to actively participate, and the level of participation is very strong.
" Although we (CSDN) have the largest number of developers, we have not been able to play its due value. There are so many intellects in the community, such a smart group of people, doing the most valuable things and doing technology The industry that drives the industry, but the development of the community does not match its value. Perhaps, the introduction of blockchain will bring community value to operate in a higher system. It will definitely change the current model and generate more unexpected Value ." Jiang Tao said.
Yuan Dao, founder & chairman of 21Vianet Data Center and chairman of Zhongguancun Blockchain Alliance, said,

" If it can be based on a credible accounting system, a credible computing system, a credible application environment, and a credible connection network, computing, billing, application platforms, and media have never existed before. Global public and trusted systems, if these systems are built on the basis of these media, they do not need to deal with traditional finance, they can exchange in real time, conduct trusted exchanges, and conduct trusted transactions. The digital economy, that is, the essence of today’s blockchain, is the fundamental goal that so many of us strive for day and night. And this is the idea of Tokenism .”
Regarding the proposition "Why did the blockchain suddenly become popular?", Yu Hao, founder and CEO of Schindler Cloud, said, " This is human nature and the inevitable law of economic development. Why is the blockchain terrible, because it not only brings information flow, but also Bringing together the credit flow, with credit can greatly enhance the ability of the organization to produce."
In the forum in the afternoon session of the salon, Wang Wei, the founder of Beijing Zhiding Technology, shared "Thinking about Blockchain Token Architecture". As an old friend of the CSDN blockchain industry, Wang Wei's views are still very sharp. He believes that the best application of blockchain is to realize the transfer of value through tokens. Other decentralized databases, tamper-proof, anonymous and other "traditional" features are anti-patterns. The value network of digital assets is his redefinition of the blockchain, and as the value carrier of the digital asset network, the connection with economic activities should be completed by the use and circulation of the certificate. Although the point of view points directly to the "traditional consortium chain", he indicated that if the token is used on the consortium chain, the advantages of the consortium chain will be greatly exerted.
Finally, Cai Yi, technical director of Beijing Zhiding Technology, shared the technology of "Ethereum Development Practice" on the spot. He introduced the development method of Ethereum from multiple dimensions such as the history of Ethereum, the use of wallets, the development of Solidity smart contracts, and the development of DApps. The participants started from the simplest HelloWorld, and gradually learned about the ERC20 development specification and the development ideas of smart contracts. In the end, he also successfully conducted a demonstration of a practical case - Pet Shop, which made the audience experience the magic of blockchain development.
Throughout the whole salon, from 9:00 am to 6:00 pm, almost no one left the venue. In the intense interaction and collision, people felt the latest trend of blockchain.
Meng Yan, vice president of CSDN, said, " Today, I want to clearly show the point of view of the blockchain token, if you can only remember one thing in my speech today, please take my point of view back. "
As today's absolutely heavy "token theory", it is opening a new journey of thought. So, how should we understand the token in depth, how to apply the token, and what changes will the token bring to the social structure?
Below, the blockchain base camp will restore Meng Yan's speech "Key Technologies of the Blockchain" in the form of an oral presentation, accompanied by a key PPT, hoping that in the hustle and bustle of currency speculation, you can calm down and think carefully. The essence of the blockchain, the essence of the certificate, so that when a new wave comes, how to do the right thing.
An excerpt from Meng Yan's speech:
Bright flags and clear views - Tokenists
Today, I want to make a clear statement of the point of view of the tokenists, divided into 5 parts:
First, the prospect of the blockchain industry situation and development direction
Second, the key concepts of blockchain.
Third, the application logic of the token
Fourth, the economic system design of the blockchain
Fifth, the knowledge and skill system of blockchain
Today, this is both a speech and an oath. I want to do something practical about the industry, what is the most missing thing in this industry right now?
1. Lack of knowledge.
2. Lack of talents.
Today, I will introduce you to the blockchain knowledge and system as a way to introduce how we should cultivate talents with blockchain knowledge and skills.
But why are many people still asking this question? In addition to the serious nerve stimulation of currency speculation, they seem to be ignorant of these companies. Why? Because these companies are almost all chain companies, they basically do not issue coins. Companies that do not issue coins and certificates are likely to be in this situation. They have done a lot, but everyone feels that their influence is limited.
As a company, their revenue and operation are all good, but compared with the noise in the currency circle, it seems to be a bit eclipsed. Let's take a look at the so-called "business model" in the currency circle. I put a quotation mark, and everyone may not agree that this is called a business model. But when the currency circle has been bustling for almost 10 years, what did it come up with?
Mining, exchanges, black market trading, ICOs, the first ICO appeared in 2013, when it was unknown and no one saw its potential. In 2016, tools began to explode, and wallets, development tools, development platforms, and frameworks became popular. At the end of 2017, a non-standard token application appeared, that is, raising cats.
We believe that the business model of blockchain is undergoing a fundamental switch, whether it is a chain or a currency circle. A revolutionary in the outer world, you may also be a revolution in the chain circle and currency circle that entered the blockchain before.
Now, mainstream institutions will take some real resources and make this chain to make this token, which is different from the ICO era. And I think it is only the last situation that really enables the blockchain to take the path of healthy development. At this time, I think the key to the core is the community + talent. From the perspective of blockchain, the form of the company will change, and you will find that the community will become very important.
What exactly is a token?
What exactly does the token contain? What does the token contain? First of all, we have to say that there are general tokens and narrow tokens. The general certificate includes what we call encrypted digital currency, bitcoin and ether are all part of the general certificate. The narrow-sense token does not include encrypted digital currency. Yuandao always talks about the separation of chain, currency and certificate. Here he mentioned that the certificate is a narrow-sense token. In more cases, we mentioned that without specifying it. Tokens, more often in the narrow sense, include ID cards, real estate certificates, credit cards, user points, stocks, bonds, options, futures, and futures contracts, all of which can be considered as part of the token, and then printed and official seals , votes are regarded as part of the token.
Three Levels of Tokens
Tokens are layered. Yuandao always mentioned the separation of tokens and tokens, the layers of tokens and tokens, and the layers of tokens. In terms of current technology, the token is roughly divided into three layers:
The first type, the basic tokens, ETH, BTC, belong to the basic tokens; the second type, the standard token; the non-standard token. what is this? It corresponds to commodities, each commodity is different, and each service is also different. The most typical non-standard token is the cat we will introduce later.
We have an understanding of the token, then we have to talk about the token economy. Token Economy Yuandao always proposes a trinity token economy. We hope that the future token economy will be digital legal currency, digital currency and non-standard token or standard token, which is what we call narrow token, an economic system of trinity.
What we just talked about is the concept of community. The token is that every individual and organization can make it without access. As long as you find a token, you can sell it for a price, especially it can be cashed and traded. commodity service cluster.
The most important thing about a token is its intrinsic value. That is to say, when I issued this token, there are my goods, services or my promises behind it, which can provide a guarantee of fulfillment.
The token accepted in a community is usually built on digital currency. For example, a certificate about a cat you sent is actually priced in Ethereum, not directly in RMB, because it is in the blockchain world and only knows what the price of Ethereum is.
So, it must be based on digital currency.
Case Study: Cryptokitties
Everyone thinks it's a combination game, and they all think it's a bunch of lunatics playing there, drawing one cat after another, and then trading there, selling for more than 700,000 yuan. Are you sick? do you have medicine? Medicine is the token economy.
Cryptokitties is essentially a company that has proposed a new standard called ERC-721, which has not yet been adopted in the Ethereum system. If it is not passed, everyone seems to not know how to use this ERC-721.
In fact, this example is a demo. I didn’t expect this demo to become popular, and a demo to become popular like this. This is something that can only happen in the blockchain era.
Look, can more than 700,000 yuan and a dozen dollars be the same concept? A difference of tens of thousands of times.
Why is this happening? It is because the price of non-standard tokens is different for everyone, the price of each individual and each token is very different from each other, and the price of the same token is also very different for different people.
Therefore, the token economy means that you can turn one of your products and services into a token and send it out, and people who like you can use digital currency to buy your token.
Three benefits of the token mechanism
First, low threshold. Anyone and organizations can issue tokens.
Second, the circulation speed is very fast, high-speed circulation.
When a token can circulate at a high speed, it can enjoy a premium - a high circulation premium.
Originally, this thing may only be worth 5 yuan, but since you estimate that after you buy it, even if you don't want it, you can sell it, and then it may be worth 7 yuan or 10 yuan, the extra 2 yuan or 5 yuan is the high liquidity premium. Tokens have such a high liquidity premium.
Third, it is highly flexible. Compared with the products, services and rights and interests represented by the pass, it is a relationship between a symbol and an entity, just like we have to go through a thinking upgrade from elementary school to junior high school, from arithmetic to algebra, from 123 to 123. It becomes ABC, and ABC becomes a code name, a symbol, etc. As we all know, symbolic operations are much more flexible than arithmetic operations, and they are more than one level higher. Therefore, as a symbol of value, the gameplay of the token is very rich, far from being comparable to the value exchange at this level.
In the future, when you actually walk into the door of the token, you will find that it can have multiple scales of value. Xiongan has established a new socialist experimental zone. It has a great idea that in addition to the RMB, there are good citizen points in Xiongan. The house in Xiongan can only be rented but not sold.
If this system is implemented with tokens, it is very simple.
There are several reasons for this.
First: Tokens are very restrictive. Since the token runs on the blockchain, the blockchain runs on the Internet. Therefore, if you dare to put a token, you cannot destroy the smart contract, and the sale will spread all over the network in an instant. What are the consequences? The consequence of the early days of our implementation of the token economy today is that all the relevant tokens you issue will quickly depreciate in value. When you want to destroy a token, all the tokens you issued will quickly depreciate in value.
Second, it is easy to supervise.
As long as the problem of anonymity is solved, the blockchain will become the strictest financial regulation in the world. You want the central bank to know every penny you spend, when it is spent, to whom it is spent, under what circumstances, and even what the money you spend will be exchanged for in the future, etc. .
So the question is, what is the relationship between token and blockchain?
Token and blockchain, the two things themselves are independent of each other, the token can develop independently, and the blockchain can also have no token.
The blockchain has created the best support platform for the token. A blockchain without a certificate is just an enterprise user data upgrade; no one believes in a certificate without a blockchain, and no one believes it. So, only a combination of the two works.
Let’s look at smart contracts from the perspective of tokens.
Smart contracts and tokens are not the same concept. Smart contracts are proposed by Ethereum. It is to be a global computer. This computer is immortal and is not affected by external forces.
There is a popular saying among cryptography people: "We believe in cryptography, not God", and there is another saying: "God put cryptography into the universe, there must be a reason. This reason is to let us create the future. Great things like blockchain.”
This is their mission to themselves.
Can the token transform the CSDN community into the world's largest software development team? I believe it can, as long as the token design is in place. Tokens can turn cultural relics, calligraphy and high-value artworks into an efficient process of dissemination.
So, how does China's economy move towards high value-added, high brand value, and personalized services? I think the token is a shortcut. If there is no token now, then we have been under the rules of the Ali era, and I am afraid that there is no particularly good way.
Outlook for the token economy
I have a few more outlooks on the token economy:
1. Standard tokens (digital currency) are the basis of non-standard tokens, but we believe that the application of non-standard tokens will be the first to be implemented, and will eventually become the main factor for the price of the underlying token.
That is to say, the master's token that only grinds two cups of coffee a day will come out first, and the app that can buy each cup of coffee with 1 coffee coin will come out later.
2. The token price in the market will become a measure of the value of organizations, individuals, goods, services and assets, and strongly motivate individual and organizational behavior. This incentive is felt by everyone now.
3. Individuals and organizations holding similar tokens will eventually form a de facto cross-border economy on the blockchain network. I don't know if there is any risk to this statement, but I think it is actually the case, because everyone cannot accept the same digital token and the same kind of token, and it actually becomes a relationship of an economic community.
Token economies can be open to each other, and each industry will eventually form several leading token economies. For example, in the education industry, there may be three or four tokens that become the most important education industry tokens, and the others will be at the end. Therefore, everyone should have time to go to various industries today to be the head.
4. The token economy can continue to create super economic incentives under the condition that the price of digital currency fluctuates smoothly.
5. We always talk about decentralization, but after you understand the whole logic of the token economy, you will find that centralization and intermediary organizations will not disappear in many scenarios, and their status will be enhanced. This is because the intermediary organization is responsible for ensuring the "hard link" between the goods, services, assets, and rights and interests corresponding to the token system.
Under such circumstances, we will find that, in fact, for a long time, the status of centralized and intermediary organizations in the token economy may be strengthened. After talking about this, everyone basically understands the token, and I don't need to talk about the token, but I want to talk about a little more mysterious later.
I just talked about it for a long time, but there is still no definition of what the token is. The essence of the token is (I discussed it with Mr. Yuan Dao and Lao Wang) The certificate of encrypted digital that can be circulated. There are two things here, one is an encrypted number, and the other is a certificate. You may not understand this matter, but circulation is easier to understand. Circulation means that it can be circulated and traded.
Finally, I will introduce the training system of Block Chain Education.
Today is not only a salon exchange meeting, but also a day when we announce CSDN Bailian Education to the outside world. Bailian Education will specialize in blockchain education. A lot of what I just talked about will be explained in a more in-depth and practical way in the training system. The key modules are Bitcoin development, Ethereum development, and client development. This is a required course.
There are elective courses in the middle. If everyone is willing to learn the design of the general economic system, we will open a small course to talk about it.
The study group will read and grind independently, and will designate a number of study books, so that everyone can read and read by themselves.
Source code analysis and contribution of well-known projects, this is amazing. Many people say that you don’t want to play fake games, you want to be real The underlying technology of blockchain. But I am afraid not everyone can accept it.
Innovation Marathon. In this link, we will bring together those who understand technology and those who do not understand technology, and those who are engaged in business and technology and entrepreneurship. They will be closed in 2-3 days, brainstorming first, and then project bidding. On-site development, of course, there are coaches to help solve a series of problems. If a good project is developed, investment, incubation and related services can be contacted on the spot.

Next, we will gradually organize the speech content of other lecturers, please pay attention to the follow-up content of our blockchain base camp official account.
Let the blockchain return to the essence of technology and applications
