Miner ranking

1. mining pools are arranged according to computing power. For example, the computing power of digyi mining bitcoin mining pool accounts for about 4% of the total network computing power, ranking among the top ten mining pools in the world. The four technology blockchains are relatively good.

3. Filecoin, the leading distributed storage project that many investors love and hate, will be officially launched on the main network from late September to early October this year. At 6 a.m. Beijing time on August 25, the official opening of the big miner test network also implies the determination of the official launch of the main network, and the market is also noisy

we are also most concerned about Suan Li Gang. We need to see whether a company has strength, not only depends on the Suan Li level, but also depends on the single-T burst rate and 24-hour mining efficiency. After all, the amount of money is directly related to our interests

with the coming of the main network of filecoin, the popularity of filecoin continues to increase worldwide, and the price of fil futures has risen rapidly since late May. Some people say that the price of fil currency will soar after the main network of filecoin goes online

we also know that from the perspective of filecoin allocation model, filecoin issued a total of 2 billion pieces, of which 70% were awarded to miners, and the 70% were used to provide data storage services, maintain blockchain, etc; The remaining 30% goes to teams, investors and foundations, with a six-month to six-year unlock period. It can be seen from the distribution model that there were few circulating tokens in early fil, which is also the reason why many people speculate that fil will soar after it goes online

let me give you some suggestions on how to participate. What are China's IPFs companies? How to choose the company and mining machinery

(1) first of all, hardware. We must pay attention to cost performance, rather than blindly choose high or low price. High price does not necessarily bring you income matching with the price. Low price may not be able to participate and lose money

(2) the second is to pay attention to mining strategy. Professional and efficient mining strategy can improve our mining efficiency. Good mining machine with a good mining strategy, you can get a good profit

(3) the third suggestion is to have a professional operation and maintenance team. Our mining machine is placed in the professional IDC room, and we also have our own professional operation and maintenance team, which is of course no problem

if you want to manage by yourself, you must consider environmental factors, such as bandwidth, operation and maintenance, etc. Professional things to professional personnel to do, in order to get better benefits. Another is that in the early stage, the storage is provided by the government or itself, but in the later stage, if the network wants to generate real market storage orders to obtain effective computing power, it also needs a special trading network to provide this service. This has higher requirements for the storage environment and operation and maintenance

(4) the fourth suggestion is to maximize the income of capital allocation. How to understand? That is to say, don't excessively pursue high performance and high storage capacity, because it takes a long time to accumulate effective computing power in the early stage. If a large number of hard disks are invested in one time in the early stage, which takes up funds, but has no effect on the improvement of income, it is a waste. Instead of this, it is better to buy more mining machines in the early stage, and expand the capacity when the storage is full in the later stage. Only in this way can the interests be maximized with the same investment.

4. China's well-known mining machinery manufacturing enterprises Yunnan ark, Shandong mining machinery and Henan Yurui machinery manufacturing< < br > mining machinery is the mechanical equipment used to directly mine useful minerals and prepare for mining, mainly including mining machinery for mining metal ores and non-metal ores; Coal mining machinery for mining coal; Oil drilling and proction machinery for oil exploitation, etc< Henan Yurui Machinery Manufacturing Co., Ltd. is located in Zhengzhou City, Henan Province, which is a professional manufacturer of heavy mining machinery and equipment. Yurui machinery integrates R & D, proction, sales and service. At present, its main equipment is crushing, sand making, grinding, mineral processing and building materials equipment. After 40 years of technical experience, it has been developing and growing. At present, it has more than 80 management cadres and engineering technicians with professional titles, three large-scale mining machinery proction bases, three mining machinery research institutes, 350000 modern equipment proction plants, and has served users in more than 160 countries and regions< Br > < br > for more questions, please consult Yurui machinery customer service< br>

5. IPFs mining machine has a count one, all liars, but also to give liars ranking?

6. Do you know wechat? It's a typical mobile social retail. To put it simply, it is to use mobile devices and social software to sell things among friends (acquaintances).

7.

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
