The blockchain industry can be divided into two parts: money cir

1. With the development of cryptocurrency, the "blockchain technology" has become popular. In China, both giant companies such as batj (network, Alibaba, Tencent, and Jingdong) and companies like didi and ofo are actively exploring blockchain technology. Throughout the world, Wal Mart, MasterCard,
IBM and giant automobile manufacturers are trying to use blockchain technology to solve instry pain points. In addition, there are "declining" enterprises such as Kodak of Japan, hoping to fight a "turnaround battle" through blockchain
What does these phenomena show? This shows that the technology of block chain has great commercial value. Everyone hopes to cultivate a new world on this unknown land. So, with the development of blockchain technology this year, it has not only been a simple underlying technology, but also formed a complete ecosystem. Now let's talk with you from two aspects of "coin circle" and "chain circle": what is the ecosystem of blockchain, and let's understand the whole picture of blockchain instry
the first section of the coin circle
in the coin circle, there are always several terms: project party, exchange, media, mining machinery manufacturer. Next, let's take a detailed inventory of what's going on
first, the project side of the coin circle can be understood as follows: all those who issue tokens are the project side. Attention, it's a coin ring. There are also some project parties that don't issue money, such as Alibaba, Tencent and Netease, which are also doing blockchain projects. They don't issue money and only focus on technology. Then these project parties that don't issue money mainly focus on the role of blockchain in data security and supply chain, which we will talk about later
let's return to the topic of coin circle project parties. For example, yilaiyun and BoChang, which are more controversial recently, are the project parties of coin circle, as well as blockchain games, which are more popular recently. They also belong to coin circle project parties
one of the subversive aspects of the coin circle project is the combination of the project and the token, which directly replaces the equity with the token, and the token can be directly circulated. This is a very revolutionary point, so that many initial projects can be more convenient for financing. After financing, the feedback token can be circulated on the digital currency trading platform, and the investors can also exit very well
this "financing investment" approach seems to be another way to realize the listing and trading of equity in disguised form
therefore, it is such a mode that makes the project side of the coin circle the nearest place to the money. They can easily circle the money, and of course they can't resist the temptation, or they have been planning for a long time and run away after circling the money. The detailed process of token issuing by the project side is generally as follows:
the first step is to build a token system, which is similar to an app application. This is not very complicated, because Ethereum is open source, similar to Android Apple system, on which developers can develop specific applications
the second step is to write a white paper, which is similar to the business plan. The white paper is similar to the business plan, mainly including the team situation, technical situation and other information of the project
the third step is to find someone to do endorsement, and find some influential instry bigwigs to promote
the fourth step is to promote marketing, find some blockchain media to push soft articles and pull cooperation, which we will mention below
the fifth step is to find financing
Step 6: go to the stock exchange, and the token begins to spread widely
Second, the exchange
with the project side, let's talk about the exchange. If the project side is a procer, then the things they proce have to be sold and traded, right? The exchange is a trading place for the token of the project party. If the token of the project side is similar to the stock, then the exchange of the currency circle is similar to the secondary market of the stock market. However, the exchange of the currency circle has more power. It has the right to audit the currency, and can decide whether to put the currency in or out
of course, if the project party wants to pay the exchange a huge amount of money charging fees, the investors who trade in the exchange also need to pay the handling fee or withdrawal fee, and the rules of the handling fee and withdrawal fee of each exchange are different. In fact, the currency fees, handling fees and cash withdrawal fees constitute the profit model of the currency circle exchange. Of course, in addition to these three profit models, the profit model of the exchange includes the "market maker" business to earn the price difference, that is, the exchange creates liquidity through continuous trading, acts as a market maker and earns the price difference at the same time
at present, e to the increasingly fierce competition in the instry, there will be less and less currency fees and handling charges, or even no need, so the proportion of conventional profits will be less and less, which leads to the emergence of other profit models, such as platform currency and leverage handling charges. Let's talk about platform currency first. Platform currency is the currency issued by the exchange: okb and coin an belong to platform currency. These platform currencies issued by the exchange can be exchanged for BTC and eth. At the same time, the appreciation of platform currency's own value can lay a solid material foundation for the development of the exchange. For users, holding platform currency can enjoy the benefits of commission discount, platform dividend, special activities of the exchange, etc, This is platform currency. Leverage service charge refers to the currency financing function on the platform, which supports leveraged transactions and charges a certain proportion of service charge to currency financing users
all of the above are actually ecosystems constructed through the exchange's own resource output. Now, the exchange is still actively planning the whole instry to obtain income, such as the establishment of capital, mine pool, wallet, incubator, Engineering Institute, fund and other ways. We believe that if the exchange wants to develop for a long time, it must lay out the whole instry chain, find new breakout points of the instry, and build a complete ecosystem. Therefore, the proportion of strategic profits should be increased
3. Blockchain media
in the past two years when blockchain is hot, there are not only a lot of project parties, but also media. At present, there are about 200 well-known blockchain media. The content on the blockchain media platform is about the following points: policy, hacker, exchange, boss and project party. In addition to words, the operation mode of blockchain media also includes community activities, such as inviting "big guys" to share in the group, so as to achieve a precipitation of high-quality content and earn some traffic at the same time
Why do we have to mention blockchain media? It's because there are some differences between blockchain media and the media in our impression. What's the difference? The difference is that there are some interest relationships between blockchain media and the above mentioned project parties and exchanges. We just said that the project side is like a "procer" and the exchange is like a "sales market". Then, the role of the media is like "advertising platform & quot;. If the project wants to sell well, it needs publicity and advertising, then blockchain media plays such a role. Therefore, the investors of some blockchain media are the project side and the exchange
recently, there has been a bear market. Many blockchain media have laid off employees on a large scale. The reason is nothing more than the shortage of projects and funds. Therefore, it is far from enough for blockchain media to rely solely on the investment of the project side, the exchange and the advertising revenue. When the bear market comes and the project side and the exchange are affected, then the media is bound to face a very cruel winter. As a result, many blockchain media are also doing token issuing by project parties (the most typical are content communities such as coin and coin car, which belong to a media platform and are also doing token issuing by project parties), or some blockchain media are doing business such as wallet selling, mining machine renting and computing power
however, we believe that blockchain media, as the media, still play the role of guiding public opinion. Therefore, we should return to the essence and be a place to deliver instry value information, rather than a place to pile up advertisements. Therefore, blockchain media should keep up with the development of technology to realize its own survival and development. Relying on the advantages of blockchain technology and based on the consensus mechanism in the token system, it can realize the reasonable distribution of the interests of the media instry. In this regard, it may have a certain imagination< Fourth, mining machine manufacturers
in the final analysis, bitcoin mining is the competition of computing power. The stronger the computing power, the greater the probability of bitcoin mining. Therefore, in the business system of the whole coin circle, mining machinery manufacturers are a very important existence. We can see from one data: in the blockchain instry of Hurun 100 rich list in 2018, the richest person is Mr. Zhan ketuan, a partner of bitcontinental, a miner. In addition, according to the prospectus, bitcoin's net profit in the first half of the year was US $743 million, an increase of nearly eight times over the same period last year. Bitcoin once occupied more than 70% of the global market share of mining machinery, becoming the leader in the mining machinery instry. Not only mining machinery, bitmainland still occupies a near monopoly position in the mining pool (that is, a mode of cooperative mining): at present, the computing power of the top six mining pools in the world accounts for 79.2%
after the invention of China's first bitcoin miner, Jianan Yun, another miner chip research company, began to engage in the research of chips in the field of blockchain and artificial intelligence. In just a few years, it has also become an internationally famous chip enterprise
in fact, as early as 2012, the United States announced that it was going to sell a butterfly miner, but many people later thought it was a scam, because it took several years for the butterfly miner to go on sale, which also made the R & D of mining machines in other countries become very scared, and they were all scrambling for time, in a sense, Butterfly mining machine is also driving the prosperity of mining machine instry. So, in 2013, the mining machine has entered a season of contention, and a large number of ASIC mining machines have been put forward: or announced research and development, or announced pre-sale, or in the form of spot: cat roasting mining machine, pigeon mining machine, TMR mining machine, biter mining machine, Rand mining Bureau, little bee mining machine, Avalon original factory and various OEM, garden mining machine, Smart mining machine and so on... Maybe you haven't heard of these mining machines, because they are basically dead. Bitcontinental, Jianan Yun and Yibang have become mining machine giants< However, as a derivative instry under the prosperity of cryptocurrency market, the price of mining machinery is closely related to the cryptocurrency Market: in the bull market, the supply of mining machinery often falls short of demand, and it is common for miners to buy Mining machinery from "scalpers" at several times high prices. At this time, mining machinery manufacturers enter the dividend period. However, in a bear market, mining machinery manufacturers will also be adversely affected. As miners' enthusiasm for mining declines, some manufacturers have to rece the price of mining machinery to recover costs. For example, when bitcoin plummeted in March this year, a certain model of mining machine sold by Huaqiangbei was on sale at a price of 5000 yuan, and the price dropped from about 19000 yuan to
14000 yuan
[summary]
at this point, we can find that whether it is the project party, the exchange, the media, or the mining machinery, it can be said that it is a kind of "one-stop"

2. Blockchain mainly solves the trust and security problems of transactions, so it proposes four technological innovations to solve this problem:
(1) distributed ledger, that is, transaction bookkeeping is completed by multiple nodes distributed in different places, and each node records complete accounts, so they can participate in monitoring the legitimacy of transactions, At the same time, they can testify together
different from traditional distributed storage, the uniqueness of distributed storage of blockchain is mainly reflected in two aspects: one is that each node of blockchain stores complete data according to block chain structure, while traditional distributed storage generally stores data in multiple copies according to certain rules. Second, the storage of each node in the blockchain is independent and has the same status, which relies on the consensus mechanism to ensure the consistency of storage, while the traditional distributed storage generally synchronizes data from the central node to other backup nodes[ 8]
no single node can record the account data separately, so as to avoid the possibility that a single bookkeeper is controlled or bribed to record false accounts. In theory, unless all the nodes are destroyed, the accounts will not be lost, so as to ensure the security of the account data
(2) asymmetric encryption and authorization technology, the transaction information stored on the blockchain is public, but the account identity information is highly encrypted, which can only be accessed under the authorization of the data owner, thus ensuring the data security and personal privacy
(3) consensus mechanism is how to reach a consensus among all accounting nodes to determine the validity of a record, which is not only a means of identification, but also a means of preventing tampering. Blockchain proposes four different consensus mechanisms, which are suitable for different application scenarios and achieve a balance between efficiency and security
the consensus mechanism of blockchain has the characteristics of "the minority is subordinate to the majority" and "everyone is equal", in which "the minority is subordinate to the majority" does not completely refer to the number of nodes, but also can be the computing power, the number of shares or other characteristics that can be compared by computers“ "Everyone is equal" means that when the nodes meet the conditions, all nodes have the right to put forward the consensus results first, and then directly recognized by other nodes, and finally may become the final consensus results. Taking bitcoin as an example, the workload proof is adopted. Only when more than 51% of the accounting nodes in the whole network are controlled can a nonexistent record be forged. When there are enough nodes in the blockchain, this is basically impossible, thus eliminating the possibility of fraud.
(4) smart contract, which is based on these trusted and tamperable data, can automatically execute some pre-defined rules and terms. Take insurance as an example. If everyone's information (including medical information and risk occurrence information) is true and reliable, it is easy to carry out automatic claim settlement in some standardized insurance procts

3. The underlying logic of blockchain is to store information in a common competitive accounting mode, which can be understood as a book that records digital asset transactions and can not be tampered with by anyone without permission
blockchain is a basic digital currency technology such as bitcoin, and it is also the only technology that has been applied to realize cash at present
now that digital currency trading has been closed in China, the vitality of the old brands who used to do well in China has been seriously damaged, and some units relying on overseas have risen, such as coin an, which is now the most popular.

4. Regular blockchain enterprises are not money, and blockchain traces the source to crack down on fake and inferior information
in the past two years, the word blockchain is very popular, and blockchain e-commerce will undoubtedly be the biggest wind outlet in the next decade. However, the instry is in chaos. Many people think that blockchain is money and have many misunderstandings about blockchain. So before we talk about blockchain, we should first talk about the idea of blockchain
blockchain is now understood by most people as "currency". There are too many coin cards in the coin circle, bitcoin and bitcoin. In fact, blockchain has nothing to do with currency. It is a technology, a business ecology and an idea. It is mainly applied in every field. It is extremely similar to the Internet. Talking about blockchain now is like the Internet 20 years ago. What did we talk about the Internet 20 years ago? When talking about its technical architecture, operating system, language, server and so on, it was said at that time that Internet e-commerce was deceptive, because many people had not been exposed to this aspect. In fact, many people have misunderstood blockchain, especially after being confused by the currency circle
When did jiuzero blockchain start? Jiuling started to investigate and prepare from 2016, and has about half a year to investigate all aspects of the blockchain. In 2017, it began to enter the field of blockchain. By 2020, it will be the fifth year. It has gained a lot of experience and achieved a lot in application. We've never played with coins, never engaged in ICO. In the first few years, we didn't make a lot of noise, that is, we should do a good job in technology, platform and browser, and apply them in traceability. We have done a good job in the application of traceability since 2017, and many procts have been launched; In 2018, more than 10000 procts will be applied in traceability. In 2019, it will be further promoted. This year, it will be further developed, and all procts will be opened up in the whole process of visualization. So at the beginning, we used it in the field of traceability. Since 2018, we have used it in the whole blockchain ecology, including blockchain traceability, blockchain invoice, sharing economy, supply chain finance, general points and other applications, as well as the platform technology services we built. We have entered this field in an all-round way, And relatively speaking, it is relatively mature and completely implemented
What's more, why is blockchain on fire now? Why does the development of blockchain reach the height of "thinking"? This is in line with the trend of the times
let's review the history of China's economic development in recent decades. The wealth of Chiang Kai Shek's time was concentrated on the local tyrants, evil gentry and warlords. Mao Zedong liberated most of the common people as peasants, and United most of them was more suitable for the situation of China at that time. Therefore, he defeated Chiang Kai Shek, overthrew the bureaucracy of the local tyrants, evil gentry and warlords, redistributed their wealth, developed the proctive forces again, and completely redistributed their revolution and distribution, Mao Zedong really realized serving the people and let the people live a good life. In the era of large collectives, people go to work in the countryside to earn points. According to the points you earn, how much food can you get. In Deng Xiaoping's time, I felt that this was not right. It might be that the efficiency was not high, and I ate a big pot of rice. Later, I started the reform and opening up. After the reform and opening up, the fields were divided into households according to the number of people. After that, the output increased a lot, which stimulated everyone's enthusiasm, increased the output and improved the efficiency. After the reform and opening up, commercial instrial enterprises began to develop
we can see that economic development is based on the needs of the times. China's reform and opening up has gone for decades, from the traditional economic era to the E-commerce Internet economy, and now the blockchain has come out, also because of the new problems of wealth distribution in the Internet era
in the Internet era, social wealth is highly concentrated on several platforms, such as Alibaba, Tencent, Internet, Jingdong, etc. the Internet e-commerce leaders have too strong a say in finance, resources, procts and other aspects. Social development has completely lost its balance. The uneven distribution of wealth has made the rich richer and the poor poorer. The instrial enterprises without money, including the whole of China, are now difficult to survive except for the monopolized central enterprises. At this time, there needs to be another revolution in business. The proctive forces must be redistributed and readjusted. It happens that blockchain is born to meet the needs of the era of transportation
the rules and mechanisms of blockchain are completely open and fair, can not be tampered with, and can not be decentralized. The oligarchs of institutions are removed to form a sharing economy for common development. Why does the government support blockchain so much? Because the government can fully enter the field of blockchain for supervision, and the privacy of citizens can be protected. Personal information in the Internet is not protected, and personal information in the blockchain is in their own hands. In the era of Internet e-commerce, oligarchs monopolize information resources. There are too many fake and shoddy procts and too many false information, so we have no way to distinguish them
at this time, the rule mechanism of decentralized supervision of blockchain emerges as the times require. Blockchain is not only a technology (it has made some improvement and promotion in the original Internet technology), but more importantly, it can solve the problems that cannot be solved by the Internet, traditional e-commerce and traditional ecology, such as traceability. Traceability in the Internet age can be falsified. A traceability source can be pasted anywhere, but the traceability of blockchain is different. The technology of blockchain is real. Everyone can participate together. Through distributed storage, everyone can get the data, and then all things can be traced, including procts and invoices, Including a person to send a message can be traced, stored, fidelity
the traceability of blockchain starts with raw materials, then proction and processing, then warehousing, sales, etc. every link should be visualized, with pictures, videos and words, which will leave traces of every link. Only in this way can we make everyone trust completely and be fair, open and transparent when there are too many fake and shoddy procts and lack of trust. In short, blockchain is to solve the problem that the Internet can not solve
when it comes to blockchain, bitcoin is the first thing that many people think of. In fact, bitcoin's contribution to the world is to put forward a rule and mechanism. Bitcoin itself has no value. It has no proct and no support. But its technology and concept are very good, because this technology can't be fake. The source code of this technology is open source and can be shared. Its technology uses the idea of blockchain
as soon as the rules and mechanisms of blockchain come out, they are sought after by everyone. However, in recent years, they have been confused by money. That kind of money is deceptive and runs counter to blockchain. On the contrary, it makes people distrust blockchain because they don't know enough about blockchain and think blockchain is money. Because if you want to understand a field, just like jiuzero blockchain has entered its fifth year, you are engaged in blockchain ecology, blockchain traceability, blockchain digital integration, blockchain technology development, blockchain browser development and so on every day. In this field, you are still learning constantly, because it is not easy to learn a field thoroughly. The reason why we have been very motivated in the past few years is because we know that it is a big trend and coming. Just like the Internet 20 years ago, many people don't believe, understand and turn a deaf ear to it. But ten years ago, Tencent, Alibaba, Huawei and other big enterprises got up. At the same time, now this opportunity is in front of us. Can we seize it? This is a question worth thinking about
finally, let's make it clear that blockchain has nothing to do with currency
for regular blockchain enterprises, the government has requirements and certification standards
standards: three basic requirements (patent, soft work, registered company in national blockchain Park, paid in registered capital, dedicated blockchain R & D funds), four landing application standards (blockchain browser, website, blockchain application scenarios, blockchain procts), five kinds of blockchain professionals (blockchain finance professionals, Blockchain digital professionals, blockchain credit management professionals, blockchain software development professionals, blockchain encryption technology professionals, and employees with bachelor degree or above who have been employed for more than one year) can get six basic subsidies
in the blockchain instry, there are at least tens of thousands of companies doing money and ICU. They all say that they are regular, but can they take out these certificates. The document points out that as long as the company has digital currency or ICO, it is not a blockchain company
under the background of this era, the ideas, rules and mechanisms, decentralized supervision and privacy distribution of blockchain can protect everyone's interests, redistribute proctivity assets, prevent the interests from being too concentrated on certain oligarchs and institutions, let everyone participate together, and let everyone exert their energy together to fight against counterfeiting, tax evasion, tax evasion, tax evasion, etc The real purpose of blockchain is to crack down on false transactions and create a conscientious ecosystem that can protect the interests of the people and provide hematopoietic function.
