The wealth myth of "one coin, one villa" is still widely spread in the currency circle, and new investors are eager to try. But in fact, a stable power structure has been formed in this small circle, from mining machinery manufacturers to large mine owners, and then to mining pools

manufacturing and selling mining machines, mining, building mines and building ore pools, the "mining circle" has become another way to get rich in the blockchain world, and mining machines have also become a little-known "big business"

according to the imagination of Nakamoto, the inventor of bitcoin, the ideal state should be "decentralized", with computing power scattered all over the world. However, contrary to decentralization, the mine pool is absolutely centralized, and more and more mining machines are connected to the mine pool

this article was first published in the Southern Weekend

"if speculation is a road of no return, then investment in mining machinery is a business that can make a steady profit without loss, and it is only a matter of time before the cost is recovered." Zhong Xi, general manager of Shenzhen Aibo times Technology Co., Ltd., calculated an account. A miner earns 200 yuan a day, which can be recovered in 120 days, and then the profit

in October 2017, in addition to his main business, Zhong Xi joined the mining army and quickly became a big boss in the mining circle. He operated many large mines in Jiangxi, Sichuan, Guizhou and other places

in fact, the business of "steady profit without loss" still depends on the continuous rise of currency price. In the past two months, the price of bitcoin has dropped from US $15000 to about US $10000, or even below US $6000 at one time, which has extended the cycle of mining machinery return. If it keeps falling, the profit will be far away

in 2012, four years after the advent of bitcoin, mass-proced mining machines appeared. Before that, mining was mainly a private activity, which could be completed by a home computer“ At that time, the home computer was the money printing machine, and a lot of bitcoin could be g up every day. " Huang Shiliang, a senior digital currency player who sold mining machines in his early years, recalled to Southern Weekend reporters

after the emergence of mining machine, mining began to be "socialized", with the emergence of mines and pools, and mining became a collective work. The indivial miner is entrusted by the mine, just like the workers on the proction line, as long as they are there, they can get paid every day

manufacturing and selling mining machines, mining, building mines and building ore pools, the "mining circle" has become another way to get rich in the blockchain world, and mining machines have also become a little-known "big business"

China has become the world's largest procer of mining machinery. Since 2012, a number of miner manufacturers have been born in China, such as Shenzhen bitquan Co., Ltd., which proces cat roasting miner, bitmainland, Jianan Yun and Yibang communication, which are now famous. In Huaqiangbei, Shenzhen, foreigners can be seen everywhere asking about the price of mining machinery with translators

recently, in an interview with the media, the CEO of bitcontinental, Mr. Zhan Ketun, said that this startup company, which has been established for only four years, had a revenue of about US $2.5 billion in 2017. Bitcontinent is known as the world's largest miner, whose ant miner has always been the hard currency of the coin circle and miner world

just like the coin circle, the mining circle also needs belief that the mechanical mathematical operation of mining machines every day can create great wealth

However, contrary to the "decentralization" advocated by bitcoin, the miner's world is moving towards "centralization". Miner dealers build their own mines. After the investors buy the miner, they are entrusted by the seller; The procers build their own mines and manage them

this process of "centralization" made the wealth of the mining circle snatched by a few people, and it was not easy for Zhong Xi to enter the core circle

calculation force "centralization"

the main function of the mine is to provide a place for scattered mining machines to operate. But it is the "ore pool" that really plays the role of integration

the so-called "mine pool" can be simply understood as "cooperative mining". The miners and the mines give the calculation power to the mine pool, and the mine pool is used as the only address to access the digital currency network for mining, and then distribute dividends to the miners according to the calculation power of the mining machine

the history of ore pool is longer than that of mining machine. In November 2010, the mine pool named slush appeared. Today, its official website says "the world's first mine pool", which is also recognized by the coin circle. Compared with the mine, the construction of the mine pool needs certain technology, and the threshold is relatively higher

the person in charge of a well-known domestic mine pool explained the principle of the mine pool to the Southern Weekend reporter. He compares mining to buying lottery tickets. If you dig alone, the probability of winning the lottery is very unstable. You may win 100000 today, but you won't in the next six months

"gather the people who buy lottery tickets together and buy them in a unified way. No matter who wins, they will be divided according to the proportion of money they pay. In the coin circle, the mine pool plays this role. " The person in charge said

it's not complicated to connect the mining machine with the ore pool. According to the operation guidelines of the major ore pools, it can be completed in a few steps, and then according to the calculation power provided by ourselves, we can get benefits from the ore pool. The miner is like a worker standing on the proction line, receiving a fixed salary every day

the mine pool with huge computing power and many mining machines has an absolute say in the coin circle and the mining circle. For example, if you want to issue a new digital currency or dominate the bitcoin bifurcation, you generally need to get the support of the mine pool. Without the support of the mine pool, no one will dig the new currency, so it is meaningless

in addition, when a hot new coin comes out, the mine pool can also use its own miners to pack it quickly and take the lead in the rush purchase of these new coins

in June 2017, when SNT and EOS were issued, Southern Weekend reporters witnessed the scene of minchi snapping up tokens. Because there are too many investors, many indivial investors can not put their funds into the designated position, but the person in charge of a mine pool can easily complete this operation

according to the imagination of Nakamoto, the inventor of bitcoin, the ideal state should be "decentralized", with computing power scattered all over the world. However, contrary to decentralization, the mine pool is absolutely centralized, and more and more mining machines are connected to the mine pool

on January 18, 2018, Emin Yun silash, a computer professor at Cornell University, and other five people co authored a paper pointing out that there is an implicit power structure behind bitcoin and Ethereum, the two major digital currencies, and mining is too centralized, in which 50% of bitcoin's computing power is controlled by the four major mines

In fact, this problem has always existed. Four years ago, the founder of Ethereum, vtalik, noticed this problem when he wrote Ethereum white paper. He wrote: "this problem can be said to be very serious. At the time of writing this article, the two largest mines indirectly controlled about 50% of the computing power of the whole network."

Up to now, this problem has not been solved. An early translator of the Ethereum white paper told the Southern Weekend reporter, "this is not a technical problem, but a human problem."

recessive power structure

in the mining circle, the top of the food chain is mining machinery manufacturers. At present, the three recognized mining machinery manufacturers are located in China. Through the proction and sales of mining machines, they get a lot of profits. At the same time, they also set foot in the construction of mines and pools, and have the right to speak in the whole coin circle

ant mining pool is one of the top two large mining pools in the world, and its computing power accounts for 17% of the total network computing power. However, according to instrial and commercial data, it was founded by bitmainland; Several investors of Jianan Yun are also investors of Hangzhou mining Pool Technology Co., Ltd., which has its own mining pool hash and mining platform, but the mining pool has ceased operation at the end of 2017

Yibang communications has set up three blockchain companies in Hohhot, Wuhai and Zhundong Economic Development Zone in Inner Mongolia. A salesperson of Yibang communications told reporters at Nanfang Weekend that they have mines and mining businesses in these three places, but these mines have been operating at full capacity, and there is no machine space to host new mining machines

"we are building a new mine in Irkutsk, Russia, where electricity charges are much lower and new mining machines can be hosted there." The source said

above the mining machinery manufacturers, it is the harvest of chip giants“ The core technology of mining machinery lies in the chip. Whoever has the chip can proce more mining machinery. " Ding Yang told reporters at Nanfang Weekend that the chips are mainly in the hands of several giant manufacturers, such as TSMC, NVIDIA, AMD, etc

since 2015, TSMC has always been the largest chip supplier of Jianan Yun. In 2015, the chips purchased by Jianan Yun from TSMC accounted for 69.62% of all the chips purchased by Jianan Yun. Since then, this figure has been maintained at about 60%. Most of the profits of Jia Nan Yun Zhi were made by TSMC

On January 18, 2018, at the presentation meeting of TSMC's fourth quarter financial report, chairman Zhang Zhongmou said that although the mobile business prospect this year is weak, the company's revenue will still grow by 10% - 15%. One of the key factors is the demand for chips e to the continuous and steady development of cryptocurrency

under the mining machinery manufacturers, there is another power structure. Jianan Yun disclosed this secret in its 2017 prospectus. In the first four months of 2017, four of the top five customers of Jianan Yun were "indivials". According to public information, three of them are well-known "wrists" in the currency circle

Wu Gang, the largest customer, was the first group of miners, and later founded haobtc, which has one of the world's top ten mines; Lin Zhipeng, the second largest customer, is the founder of Xiaoqiang mining machinery. He has been engaged in the proction and sales of mining machinery for a long time. He has been cooperating with Xie Weiqin, the sixth largest customer; Wang Jin, the third largest customer, founded bitbang, a coin circle information website

these big customers are not simple miners, they all have their own influence in the coin circle. Mechanical operation of the mining machine to bring them income at the same time, also brought the right to speak

according to an insider in bitmainland, most of the big customers in bitmainland are big guys in the currency circle. However, bitmainland officials declined an interview with the Southern Weekend reporter. The company's Public Relations Department responded that it was not convenient to disclose the content because it signed a confidentiality agreement with its customers

"one coin, one villa" wealth myth is still widely spread in the currency circle, and new investors are eager to try. But in fact, a stable power structure has been formed in this small circle, from mining machinery manufacturers to large mine owners, and then to mining pools

most of the new entrants can only make the harvested "leeks"

4. Ha ha, what do you do, brother? It is estimated that we are peers. Avalon's chip is hard to find. At that time, I was crazy to find it. There is a company in Shenzhen that specializes in Avalon. Its name is Shenzhen Avalon Electronics Co., Ltd. in Huaqiangbei. Their QQ is 1816404459.. However, this company only does wholesale, and has to order 1000 units
coding is very hard, remember to add points^_^

5. The selection of mining machines depends on the computing power, the power consumption and the historical reputation, including the stability and after-sales service of the machines
computing power is the ability of a machine to perform operations, that is, how many hash operations can this machine perform per second. At present, the computing power of the mainstream bitcoin miner is 14T, that is, hash collisions of the 13th power of 14 times 10 per second
power consumption is an indicator of the power consumption of the miner ring operation. Electricity consumption will have a huge relationship with mining costs. Generally, a miner will operate 24 hours a day to excavate, so the power consumption sometimes seems to have a small difference, but in fact, the cost gap is relatively large
here is another little knowledge, that is, digital assets of the same algorithm can be mined by the same miner. For example, bitcoin miner can also dig bitcash, Ethereum miner can also dig Ethereum classic
for more professional knowledge, it is recommended to consult the honeycomb miner. There are professionals to help you select and answer for you. The boss comes from the fire coin, and I feel reliable after personal experience.

6. The main reason is that our country has strict control over foreign exchange
there is another way to solve the problem of not recharging the PayPal account to the US dollar. It is through finding a person to exchange PayPal dollars (using RMB in a certain proportion of exchange), the other party pays the US dollar through your PayPal account to your PayPal account, and you send the remittance through Alipay or domestic bank to the right side, so as to solve the problem of recharging the PayPal account to the US dollar. At present, only local banks in the United States can recharge the PayPal account in US dollars (for example, the Bank of America account you applied for in Shanghai can't be recharged in PayPal), and the PayPal account can't be recharged in RMB.
friendly reminder: you need to find a reliable payer in this way. At present, PayPal certification supports a variety of international credit cards. Certification is very simple. It is recommended that you apply for an international credit card of China Merchants Bank, and you can pay directly through the credit card when shopping.
the work of PayPal consultants is not only to guide customers to register, but also to maintain their accounts in the later stage, for example, customers can't receive the money they call you, If you can't withdraw cash from your bank account or some people have problems with limited accounts, you can ask PayPal customers to help you solve them. Even PayPal consultants will teach you some tips on how to use PayPal, how to use PayPal to save handling charges, and risk control knowledge. If you use it for the first time, do you need a consultant?

When the Internet was just born, the amount of data on the whole network was small, so the simple and convenient transmission mode of HTTP protocol is very easy to use. However, with the development of the Internet, the amount of data on the network is increasing, and the disadvantages of HTTP protocol are graally revealed

about its concept :

1 the dependence on the server storing data is too strong

if there is a problem with the server, the data may be lost. I believe many people have experienced the phenomenon of 404 pages lost when opening a web page, which may be caused by the failure of the data server

When the amount of data required by users is too large, the burden of server transmission will be very heavy, which directly affects the transmission efficiency. If the data users need is compared to water flow, then the bandwidth is the ditch and the server is the reservoir. In a certain period of time, the flow from the reservoir to the ditch is also fixed, and the greater the demand of users, the more time cost will be spent

3 at present, the Internet is very dependent on the backbone network

at present, a large number of Internet data are transmitted through the backbone network, once adverse factors occur, leading to the damage of the backbone network, it will inevitably affect the data access of users

about the second question:

enter the landmark SEG square of Huaqiangbei, and the floor is in the guide. On the 3rd to 5th floors, some merchants have put out various types of poster advertisements, and the shops are basically occupied by the merchants

it is reported that after the mining machinery business started, the seller also had some new practices, and some merchants found a new way to provide derivative services to attract customers

for example, in the custody business, businesses find stable power and sites, and buyers choose custody after purchasing mining machines, and there is no need to consider other issues after paying the custody fee. In a shop with a signboard of "ASUS computer", the Sales Department tried to promote this model, and used a calculator to input various numbers skillfully to demonstrate back to this cycle

notes: about the above questions, I will provide you with my own personal views, and I will also send you a little skill Internet search results - IPFs learning for you

8. According to the official news, bitmainland will sell a batch of the latest generation of mining machines s19j again, with a power consumption of 90th / s, 3100w and a power consumption of 34.5j/t. This batch of mining machines will go on sale at 15:00 on February 25. The specific quotation will be announced in real time<
