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. The oil procing countries in the Middle East are not rich countries. The gap between rich and poor countries aggravates the oil boom. There is a big gap soon. Therefore, some countries renew the social landscape of Arab oil rich countries. The urban development of Gulf countries has always been impressive. High rise buildings have sprung up on the earth in different countries, storing a large number of goods and entering supermarkets, Procts that can be bought by the state, canned America, West Germany and Japan, home appliances, Italy fashion, French perfume and cosmetics... American luxury "Chevrolet" driving on the highway, West German "Mercedes Benz" car; Government buildings, schools, hospitals and every family's residential buildings and furniture are very particular. The common air conditioning makes it hard to cover in the hot tropical desert climate. However, in this land, it is very difficult to live in another corner of people's lives. The level of proctivity is low, unemployment is increasing, inflation, social, economic and cultural backwardness. Is Yemen a good harvest in the street? Is it a foreign advanced luxury car? There are often long lines and few high-rise buildings in the street e to the lack of people in the shop. You can still see "abubu" passing by in the mud house, let alone household appliances and air conditioners. What a contrast! In the Middle East, oil development will only aggravate polarization and widen the gap between rich and poor countries. Of course, on the one hand, absolute poverty, on the other hand, relatively poor. There is a gap between the rich and the poor between the oil procing countries and the non oil procing countries in the Middle East. There are also the oil rich countries and the oil poor countries, and the small oil countries. However, there is still a gap between the rich and the poor in a country. The wealth of construction businessmen in the Middle East is almost unprecedented in the era of oil prices, and the nobles in the Arabian desert are also rich in oil. In fact, the "black gold" Allah created a generation of rich tycoons. Rich oil procing countries are basically made up of two groups of people A) Saudi Arabia's first modern kingdom of King Abdel Aziz, the Arab ruling royal family has married more than 300 wives. When countless children were born, only 43 were officially recognized as grandchildren, more than 100 were grandchildren, and more than 500 giant surviving sons - grandchildren, who have three uncles and descendants, that is, male members of the royal family. The Prince now has about 5000 people, more than 17, 000 people in the whole family, the largest royal family in the world. Saudi Arabia's huge oil revenue, most people fell in the hands of the royal family. According to official data, the state allocates $300 million from the budget to Saudi households every year, and the actual payment is dozens of times larger than that of Lhasa. Each Prince's oil income, as well as billions of dollars, receives $60000 a year, 5000 monthly living subsidies and 17000 royal family members. They speculated that the prince amassed wealth. Later, they learned that the national development plan purchased land at a lower price in advance, and then sold it at a high price for the government's or enterprise's huge profits. An instrial enterprise in Jul, a monarch, received $2 million from the sale of land; Others made $8 billion from the sale of Prince Riyadh airport. Some of Prince's shareholders in the private sector, banks, and three Welsh acts have 7500 shares (100 rials per share, or $29.8) in arab bank risk shares. Some Welsh companies act as middlemen or agents for foreign companies and receive all commissions and kickbacks. The $4 billion personal property Prince's weapons contract. At the same time, the prince gave tax exemption to all kinds of state-owned enterprises that offered interest free loans, so that they could become rich and fined. According to us "Newsweek", the Saudi royal family's wealth has reached 80 billion US dollars, among more than 800 millionaires. The Khalifa family, the ruler of Bahrain, now has 400 people, one third of the country's national income. It is estimated that the 18 rulers of the Emir isa bin Khalifa Suleiman Caliph belong to them. Qatari ruler al Thani family (belonging to the bernulitamim tribe), his family has more than 2000 people, most of the national revenue belongs to them. The former king of Iran, King Pahlavi, is a billionaire. It is estimated that his wealth has exceeded $20 billion. Iran was formed under the leadership of the king. Rich people, including members of the royal family, senior officials and generals, including big capitalists and landlords, were known as "Iran 2000". Relying on power, blackmail and various means, they accumulated a lot of wealth 2 Do you have a relationship with the royal family or do you rely on personal struggle to become a part of this wealthy man? The main contractor, building materials and construction equipment, real estate speculation, large wholesalers and retailers, currency exchange, shareholders and household management, and some people operate various instries, commerce and banks at the same time. They constitute a bourgeois oil country with a small number and a short history of instrial or commercial operation, but they are developing rapidly. Many of them are upstarts. They not only provide various enterprises at home, but also invest a lot of money abroad to become millionaires. Some of them are e to the high social status of their families. They are also ecated in the West and have relatively good conditions. His father is King Faisal, the chief consultant. He graated from Harvard University and became an entrepreneur at the age of 30. He has his own share of assets. Adenan kashao Ji is described as a legend. He is of Turkish origin in Saudi Arabia. His father is the first king of Saudi Arabia, King Abdel Aziz, the Royal mountain, so he has a close relationship with the royal family. After returning from his research work at Alexander Victoria College and Stanford University, he got the proction and operation right of a gray nylon board and opened a gray Nigerian National Board company. On this basis, he established "business and Emperor" - Sany holding company. In 1978, the company had assets of $400 million. In the mid-1970s, kashaoji was engaged in real estate business in many parts of the world. He successfully used his relationship with the royal family to squeeze into the huge arms trade market. He considered becoming the company when he was 29 years old. After that, he became a variety of arms manufacturers in the world and a leading Arab enterprise in the country. He got rich rewards, In just a few years, likashaoji became the richest man in the kingdom of Saudi Arabia. When he was about 40 years old, his assets amounted to $4 billion and he lived a fantastic life. Suleiman olayan is the most famous diversified giant in the UK, with a considerable commercial fleet of about $1.2 billion in assets. At the same time, the reputation of securities investment in the United States; In 1989, he was elected as a member of his youth to work for the supreme Arab and American Petroleum Commission. Saudi Arabia olayan group is the agent of many imported goods, in the sales and maintenance of automobile and construction equipment, and has to carry out transportation, insurance, real estate, leasing and other tourism services, as well as international large companies have more cooperation projects, metal processing, drilling rig maintenance. In addition, the group has many properties in Saudi Arabia and abroad, and has invested abroad, including real estate securities in the United States and Western Europe, with a total amount of more than US $50 billion. It is the second largest business group in Saudi Arabia. With more than 20 years of hard work, it was established in 1980 as a powerful family business. The group has more than one billion US dollars of annual sales and about 100 US dollars of profit. Although Jamil also opened up other sources of income, such as real estate, overseas investment. He is in charge of the management of the RAND overseas investment company in Monaco. His son yousufu founded Karo Jamil, whose property is estimated to be at least $5 million. In today's Gulf countries, it has maintained the commercial reputation of the famous plutocrats, such as kanubarin, Suleiman, kongfu, Pharisee and gaiyibi. As the vice president of Jeddah chamber of Commerce of the Ministry of Commerce, Abdel Aziz Suleiman, the leader of the suhman family, is the leading role of Saudi Arabia's financial instry. Saudi Arabia is the largest county in the country, and the family has opened a bank to support the agriculture of wheat exporting countries as China's largest private agricultural operation. Are these people worth hundreds of millions of dollars? The more assets they have, the more they are not members of the royal family and earn tens of millions of dollars a year. They rely on their own business acumen, know how to use oil to bring good business conditions and preferential policies of the government, so as to establish their own family business and expand their wealth. Of course, it can not be denied that their wealth also contains a lot of sweat, driven by wages. Aristocrats, rich businessmen, the upper rulers, extravagant, extravagant, wasteful. They buy airplanes, yachts, villas, eating, drinking, gambling and enjoying the best he can. Miss America, who took over the story of the stewardess of the Saudi prince plane: when she visited the prince's plane for the first time, she couldn't believe her eyes. The captain of the cockpit seat was leather, including the seat belt buckle. All the metal parts were made of gold; Standing on the plush sofa in the engine room, on the bed in the bedroom, with red fox skin sheets, pillows and blankets, and minks with mink skin; Gold shower and sitting in a gold pool bath room; Game room, art wall hanging tapestry, the other side of the wall is in a big mirror, showing the whole plane everywhere rich and luxurious. About prince in the airport parking groups of private aircraft, ready to go abroad to enjoy. Former King Khalid of Saudi Arabia privately owned Boeing 747 aircraft, with the implementation of equipment on the heart surgery ship, his private yacht is up to 200 feet, worth 12.6 million dollars. Adnan kashaoji has five airplanes and three sea yachts. One of them is called "bonabila", which is an 86 meter long sea palace, helicopter lift, nightclub and the most modern operating room. In order to show his wealth, Adnan also cast the original gold into the name of a yacht and recast all platinum. Oil prince, not only in its domestic buildings dotted with magnificent palaces, but also abroad to buy, build villas. Along the northwest of the eastern Mediterranean, Mang, Monaco, Antibes, Cannes and Toulon are the most famous and wealthy gathering coasts in the world. Buying a house there has become a symbol of rich international status. Qatar, Abu Dhabi, Saudi king, Lebanon businessman Anthony TANU, marshal Jordan Emir and other luxury apartments on the coast, arms dealer Adnan has 12 places in the world's luxury villas, only in Kot D & 39; Azur's this has been built and several residents belong to him. Some oil millionaires are building or shrinking here on a whim. For example, Saudi Arabia has two brothers, a 10000 square meter land and an area of 1000 square meters to build two residential villas, in front of the house with a panoramic view of haijingwan in Cannes and antybu. After the completion of the house, the two brothers suddenly found that they did not intend to live. They decided to sell the house and find customers without any difficulty. The other side was willing to offer 100 million francs and pay them off in one lump sum. It was built to use the port of an international giant and managed in the international cruise club, with only 19 berths. Adnan took part in the first investment in 1984 and won the title of honorary citizen of the city and awarded the order of Antibes. Qatar's "Al ho people" Emir stops at the port all year round. Saudi King Fahd is the world's largest yacht, 146 meters long, and it has a special berth at the wharf. There is such a reason
