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"

In fact, it's not difficult. When we use mobile phones everyday, there will be some background applications, which will be "killed" after restart. However, if the mobile phone is hacked and rebooted, it will enter a high load state again, and the system running memory will be used up quickly. Therefore, if the mobile phone is stuck, hot or dead for no reason, it may be g

it is possible that hackers steal all the information before using mobile phones to "mine" cryptocurrency. People will not only encounter problems such as cell phone stuck, fever and even crash, but also other financial losses

moreover, it is worth noting that some mobile mining apps, in the name of "mining", allow users to invest money and continue to develop offline

1. First of all, connect the network cable, plug the network cable into the network cable interface of the mining machine, and remember to plug it tightly. Only when the miner is connected to the Internet, there is no limit to the broadband

extended data

users can buy bitcoin, at the same time, they can also use computers to "mine" bitcoin according to a large number of calculations. When users "mine" bitcoin, they need to use the computer to search for 64 bit numbers, and then compete with other gold miners by repeatedly solving puzzles to provide the required numbers for the bitcoin network. If the user's computer successfully creates a set of numbers, then they will get 25 bitcoins

e to the decentralized programming adopted by the bitcoin system, only 25 bitcoins can be obtained every 10 minutes, and by 2140, the maximum number of bitcoins in circulation will reach 21 million. In other words, bitcoin system is able to achieve self-sufficiency, resist inflation through coding, and prevent others from destroying these codes

4. Now four years later, you are an old hand and have a lot of money, right? Now it's a bear market again... 2w7, a bull market of 130000 at the end of last year, let most people rush in together, and now they are in a desperate situation

Green currency is a digital currency platform

the World Environmental Protection Foundation hopes to invest part of users' funds into environmental protection through the appreciation of environmental protection currency. The mining method of environmental protection coin is cloud mining machine. After the user registers the environmental protection coin account, the platform will send the user a miner. But the delivery machine has only one month's service life. After the expiration, users can directly purchase the machine with the environmental protection money they have g

precautions:

in the view of experts and instry insiders, green finance has many opportunities and great space for development. Relevant data show that ring the 13th Five Year Plan period, China's green instry needs to invest at least 2 trillion yuan a year, and the demand for air governance in the past five years is about 1.7 trillion yuan, of which the government's financial funds can only provide about 10% to 15%, and a large amount of funding gap needs financial channels to support

from an international perspective, the development of green finance has become a world trend. Many countries represented by China are strengthening the top-level deployment, and more and more international financial institutions are actively participating in the green financial market. Taking green bonds as an example, it is estimated that the global green bond issuance will reach US $300 billion in 2018

First of all, gold bars can only be obtained by doing their own tasks or selling materials, but those tasks are limited. Anyway, all small partners can do them, so we won't say much about them. Another is to sell materials. The prices of materials are different at different stages of the game. With the upgrading of most players, the prices of primary materials will be greatly reced. So we'd better sell the most front-end materials and earn the most gold bars

it's on the far right side of the map, where the infected person is very strong. Novice players can use the rock racks on both sides to lure the infected person to come over, and then run to open the treasure box. The action must be fast. When the infected person comes back, they can open the treasure box and escape. In addition, the ruins of the castle can also get polymer coating, here only you sneak in, just to the level 5 manor players can't fight. Those krypton players can sell their equipment by washing out good properties, while ordinary players can only sell materials. This is also the fastest way to earn 100000 gold bars

7. WEC intelligent miner starts to refresh the daily settlement after 2:00 a.m. every day, and the distribution is completed in about 5 hours.

8. Peace elite gold island mode is very popular among all players. What's the location list of peace elite gold island mining machine? After watching the wonderful live broadcast of peace elite anchors, many novice players have joined the team of looting. Next, Xiaobian will share with you the new position of Golden Island mining machine< First, a list of mining machine locations

after entering the game, players need to open the small map in the upper right corner. From the map, you can see a small icon marked with three numbers 123. On the icon, there is a pattern similar to the entrance of a mine and a harvester. These three positions are the location of the harvester. Players only need to reach a miner, they can pass through the three miners through the miner. Of course, on the way, they must be careful of the enemy players' attack< 2. Entrance of mining machine

the entrance of the mining machine is a fortress like a tent. Before you go to the location of the mining machine, you can go to the nearby buildings to search for some gold bars and buy some combat equipment. In this way, even if you encounter an enemy near the mining machine or inside the mine, you can also protect yourself and snatch the other party's gold bars< (3) entering into the mine

& 65532

when you enter the mine from the earth fortress, you need to buy sticky bombs with gold bars first, so that you can blast the entrance door of the mine and enter the mine smoothly. Inside the mine, you can see a very large golden machine, which can proce gold bars! On the operation page of the miner, the words "start miner" will be displayed. After clicking, the miner can start to proce gold bars< 4. Mine crossing

& 65532

after defeating the workers in the mine and getting all the gold bars proced by the mining machine in the location, the player can walk through the three mines through the mining car in the mine tunnel near the mining machine.

9. In 1985, Hawking lost his language ability, and the only tool to express his thoughts was a computer voice synthesizer. He uses only a few moving fingers to operate a special mouse, selects letters and words on the computer screen to make sentences, and then plays the sound through the computer. It usually takes 5 or 6 minutes to make a sentence, and it takes 10 days to prepare for an hour's recorded speech. A brief history of time, a popular science work, was written in 1988. By October 1995, the book had a circulation of more than 25 million copies, translated into dozens of languages, and its Chinese translation had been published
he is the author of large scale structure of space-time (1973), general relativity: Einstein's Centennial review (1979), hyperspace and superheavy forces (1981), the beginning of the universe (1983), and a brief history of time (1988)
in 1990, Mrs. Jane waicurie, who has been married for 25 years, made a comprehensive examination of known chemical elements and all compounds, and obtained important findings: an element called thorium can also automatically emit invisible rays, which indicates that the phenomenon that elements can emit rays is not only the characteristics of uranium, but also the common characteristics of some elements. She called this phenomenon radioactivity and elements with this property radioactive elements. The radiation they emit is called radiation. According to the experimental results, she predicted that the minerals containing uranium and thorium must be radioactive; Minerals that do not contain uranium and thorium must not be radioactive. Her prediction was fully validated by the examination of the instrument. She excluded minerals that did not contain radioactive elements, focused on those that had radioactivity, and accurately measured the radioactive intensity of the elements. In the experiment, she found that the radioactive intensity of a pitchblende is much higher than expected, which indicates that the mineral in the experiment contains a new unknown radioactive element, and the content of this element must be very small, because this mineral has been accurately analyzed by many chemists. She decisively announced her discovery in the experimental report and tried to prove it through experiments. At this critical moment, her husband, Biel Curie, also realized the importance of his wife's discovery and stopped his research on crystals to study this new element with her. After several months of efforts, they separated a substance mixed with bismuth from the ore, which is far more radioactive than uranium. This is polonium, which was later listed as the 84th on the periodic table. A few months later, they discovered another new element and named it radium. However, the Curies did not immediately get the joy of success. When they got a little bit of the new element compound, they found that the original estimate was too optimistic. In fact, the content of radium in the ore is less than one millionth. It is only because of the high radioactivity of this mixture that the substances containing trace radium salts show radioactivity hundreds of times higher than that of uranium
divorce. On September 16, 1995, he married his nurse Elaine Mason.
