Video card (graphics card) full name display interface card, also known as display adapter, is the most basic configuration of computer, one of the most important accessories. As an important part of the computer host, the graphics card is the equipment of digital to analog signal conversion, and it undertakes the task of output display graphics

the graphics card is connected to the main board of the computer, which converts the digital signal of the computer into an analog signal for the display. At the same time, the graphics card still has the ability of image processing, which can help the CPU work and improve the overall running speed. For those engaged in professional graphic design, graphics card is very important. Civil and military graphics chip suppliers mainly include amd (ultra micro semiconctor) and NVIDIA (NVIDIA). Today's TOP500 computer, including graphics card computing core. In scientific computing, graphics card is called display accelerator

2. From cheap electricity to centralized mining, China's resources and environment provide bitcoin miners with many advantages. In recent years, bitcoin miners have used cheap electricity to expand their business in coal rich regions such as Xinjiang and Inner Mongolia, which are home to the founders of some of the world's leading mining companies

with the rising price of bitcoin, more and more people join the bitcoin mining business. Accordingly, mining consumes more and more energy. Obviously, our government is also aware of this

according to the requirements of the document, regulators require local governments to take measures related to electricity price, land use, tax and environmental protection to guide bitcoin miners to withdraw from the business. According to foreign media reports, regulatory authorities are mainly concerned about the money laundering and financial risks involved in the shutdown policy, but excessive power consumption is also a factor that can not be ignored. In principle, bitcoin mining consumes a lot of power because every time a new bitcoin is proced, it needs to solve the complex mathematical problems through the encryption process performed by a high-performance computer. Mining calculation process is used to verify bitcoin transactions in the blockchain to ensure security, but the disadvantage is that it consumes a lot of energy.

3. The difference between mining by Sifang computing power users and mining by mining machines purchased by indivials is as follows:
①. Early stage investment: Sifang computing power provides, which saves users this link. Indivial: purchase of mining machine, selection of mining machine model, preparation of power facilities, etc
2. Field equipment: provided by Sifang computing power, users can save this link. Indivial: rental site, mining machine support rack, noise elimination equipment, etc
3. Software assembly: provided by Sifang computing power, users do not need to master professional knowledge. Indivial: learn professional software assembly knowledge or hire a special person to operate
4. Maintenance: Sifang computing professional technical team, all-weather supervision and maintenance. Indivial: employ professionals to supervise and maintain all day long< (5) electricity and electricity charges: professional large chain mines and users do not need to pay electricity charges. Indivial: the power facilities in the residential area are unstable, the price is high, and the cost-benefit of mining is unbalanced< (6) risk taking: users obtain BTC net assets. Indivial: the equipment investment in the early stage is huge, which is easy to form heavy asset operation, and the income and investment in the later stage are likely to be unequal.

4. Mining refers to the use of computer hardware to calculate the location of bitcoin and obtain the process, known as mining. Every other time point, bitcoin system will generate a random code on the system node. All computers in the Internet can search for this code. Whoever finds this code will generate a block, and then get a bitcoin. This process is called mining

computing this random code requires a lot of GPU operations, so the miners purchase a large number of graphics cards to get bitcoin more quickly and make profits
bitcoin has a halving effect, that is to say, every four years, the number of bitcoin will be halved. In this way, the computing power of bitcoin will increase, that is, the difficulty of mining will increase. Under normal circumstances, mining generally refers to the use of mining machine, that is, the computer to dig. These all refer to the single operation, or the operation of the whole mine. Cloud computing power mining refers to mining with multiple people. You can participate in mining as long as you invest a small part
the usual steps of bitcoin mining are "purchase miner - deploy miner - set miner - get profit", but the deployment of miner is affected by many factors, such as electricity price, site, temperature, noise, operation and maintenance, etc. These barriers need certain conditions and knowledge to eliminate, so it gives birth to a sub mole of mining instry - cloud computing power
cloud computing power is a remote mining mode. Users purchase cloud computing power contracts through the platform, rent computing power mining, and obtain revenue regularly. The advantage of cloud mining is that users don't need to deeply understand the mining principle and various software and hardware, or buy expensive mining machines, and they don't need 24-hour maintenance. As long as they place an order, they can participate in mining, which is similar to purchasing usufruct procts
for mine owners, renting and selling the right to use the computing power for a period of time to customers at a price slightly lower than the self operated mining income can quickly return cash, purchase the latest mining machinery in advance, expand the proction scale, and win the possibility of profit in the forward market. To some extent, it can also retain mining machinery at a low currency price, transfer risk, and hedge the single risk of self operated mining business< However, compared with direct participation in mining, cloud computing power also shows the following disadvantages:
even if the platform fully displays relevant information such as mines, mining machinery, cooperation and teams, it is still difficult for users to judge the quality of computing power, real-time operation status (such as power failure, site temporary inspection) or real revenue data behind the platform
the risk of speculation in bitcoin (short-term trading to earn spread) is higher than that of Tuen bitcoin (long-term bullish), but most Tuen bitcoin investors often lack judgment on short-term price changes and "get off early". Cloud computing power brings a small amount of bitcoin income to investors every day, which is also controlling investors' frequent operation in disguised form. Therefore, for many people who like bitcoin, there will be such a saying: "it's better to dig money than to fry money"
the market opportunity of cloud computing power is to provide indivials with a more neutral way of investment. The threshold is lower than that of self built mines, the risk is lower than that of short-term operation, and the cost is lower than the market price. It also allows mines to share the costs and risks and obtain more abundant cash flow
the main risk of cloud computing power lies in the authenticity and stability of computing power behind the contract. In our long-term contact with the mining instry, the high-frequency words we hear are "pit": reasons for power failure beyond common sense, various incidents ring the transportation of mining machinery, constant interference of viruses and extortion, fluctuation of futures and tardy spot, obstacles of cross-border trade, and team ghosts that can't be prevented. Therefore, real and stable computing power is scarce to a certain extent, Behind it is often years of experience. As an information intermediary, cloud computing power platform will become its core competitiveness in how to help users select high-quality cooperative mine cooperation, design friendly and attractive procts, formulate professional and transparent instry standards, establish disaster recovery plans to deal with various risks, and provide high-quality services throughout the whole process of investment
of course, mining is a long-term development instry, and cost recovery also needs a certain period, so whether you can make money mainly depends on whether you can stick to it.

5. Different from bitcoin mining, IPFs mining does not require high electricity charges, but has certain requirements for network bandwidth and stability. Therefore, if IPFs mining machine wants to give full play to its functions, it also needs supporting "mines" and large-scale cluster mining. You can go to Renren mine website to learn about IPFs mining.

6. In January 2013, Avalon released the 60g / s miner specification and accepted the booking. In January 2013, Avalon delivered the world's first commercial bitcoin ASIC miner, and the core developer of bitcoin network, Jeff
garzik, was fortunate to be the owner of the first commercial ASIC miner.
the most difficult mining problem was 0, and the computing power was about 2p at the beginning of 2013, and now it has reached 100p

7. Theoretically, both CPU and GPU operations can be mined
in the early days of the advent of a virtual currency, it was relatively easy to mine. Maybe a CPU with strong enough performance could easily mine the currency
as it becomes more and more difficult to dig money, the CPU has already been unable to cope with the huge computing power required for mining, and the terrible performance of the large-scale stream processor parallel computing in the GPU core of the graphics card is more suitable for mining this kind of parallel computing
therefore, today's professional mining machinery has become the world of GPU and professional chips, in which CPU plays the most coordinating role. Moreover, with the increase of mining difficulty, the demand for the display memory capacity of the mine card is higher and higher. A few years ago, 2-3gb was enough, but now 6GB may not be enough.

Although many investors know nothing about bitcoin mining, they still can't resist the temptation of bitcoin price and plan to invest in the mining army. So if you also want to mine, I believe you will have a question in your heart: "what is a bitcoin miner? What is the principle of bitcoin mining machine? " To solve this problem, let's remember some popular science today

origin of bitcoin

to fully understand the origin of bitcoin, we have to mention the existing financial system

bitcoin mining machine specially used for mining. The popular digital currencies in 2013 include bitcoin, Leyte coin, zeta coin, pennies (Internet), invisible gold bar, red coin, pole coin, BBQ coin and prime currency. At present, hundreds of digital currencies are issued all over the world

with the orderly implementation of cashless society, banknotes will inevitably disappear in the long river of history with the passage of time. The future digital currency is believed to be similar to bitcoin, but it is by no means a limited supply. But when the human ability to proce wealth can be completely matched by the computing power of the computer, the issuing speed of e-money is directly proportional to or slightly exceeds the computing speed of the computer to create moderate inflation. In the future, while mining, it is also creating value rather than wasting electricity. In the end, the small changes in proctivity of digital currency match the difficulty of computing power, which may be the final form of human currency
