What does miner rely on to understand graphics card

1.

In short, mining is the use of chips for a random number related calculation, get the answer in exchange for a virtual currency. Virtual currency can be exchanged for the currency of each country through some way. The stronger the computing power, the faster the chip can find this random answer. Theoretically, the more virtual coins can be proced per unit time. Because it's about random numbers, you can only get rewards if you happen to find the answer

In his paper, Nakamoto stated:

"in the absence of central authority, it not only encourages miners to support bitcoin network, but also enables bitcoin's currency circulation system to have the initial source of money injection."

Nakamoto compares the generation of bitcoin by consuming CPU power and time to the consumption of resources by gold mines to inject gold into the economy. Bitcoin mining and node software mainly initiates zero knowledge proof and verification transactions through peer-to-peer network, digital signature and interactive proof system

each network node concts broadcast transactions to the network. After these broadcast transactions are verified by miners (computers on the network), miners can use their own work proof results to express their confirmation. The confirmed transactions will be packaged into data blocks, and the data blocks will form a continuous data block chain

Nakamoto himself designed the first version of bitcoin mining program, which was later developed into the first generation of widely used mining software bitcoin, which was popular from 2009 to mid-2010

each bitcoin node will collect all the unconfirmed transactions and gather them into a data block. The miner node will add a random adjustment number and calculate the SHA-256 hash value of the previous data block. The mining node tries again and again until it finds the random adjustment number so that the hash value is lower than a specific target

at the earliest, bitcoin miners were mining through Intel or AMD CPU procts. But because mining is a computing intensive application, and with the continuous improvement of mining number and equipment performance, the difficulty graally increases, now using CPU mining has no profit or even loss

as of 2012, since the first quarter of 2013, miners graally began to use GPU or FPGA and other mining equipment [5]. At the same time, a large number of ASIC devices were launched in mid 2013

since July 2013, the computing power of the whole network has shown a straight-line rise e to the large number of ASIC equipment put into operation. Based on the average computing power in July 2013, all CPU mining equipment has been unable to generate positive revenue, and FPGA equipment is close to no revenue

according to the estimation of average computing power in September 2013, the existing small ASIC mining equipment developed for indivials will also be close to no positive revenue in the next 1-2 months. A large amount of computing power is monopolized by cluster ASIC mining equipment with 5 th ash / s or more. Because of no profit, indivial mining is almost squeezed out of mining groups. Some bitcoin miners have raised funds to build machine rooms and install a large number of mining equipment in places where low-cost electricity can be obtained

in order to save the cost of mining, some bitcoin miners make mining programs into malicious programs to infect other people's computers on the network to mine for themselves

2. The main reason is that the quality of the graphics card can not be guaranteed
for mining, all mining machines do not shut down for several months. And the graphics card is always full of work, there is no time to rest
some of them are still used in overclocking mode, which is much more intensive than the personal home graphics card used for several years.

3. Graphics card miner is a mining device which supports a variety of mining algorithms. Different from ordinary graphics card, it is assembled by a number of high configuration graphics cards, customized and highly compatible chassis, professional mining rack and other equipment specially designed for mining needs. You can pay more attention to the interstellar bit miner.

4. A device that digs bitcoin or Leyte or other electronic money. Usually a computer motherboard has more than one high-performance graphics card.

5.

Mining is a work that needs a lot of computing power to support. The reason why we use the graphics card mining machine is that the graphics card is easier to carry out a lot of repeated calculations than the CPU, so the general mining machine of the graphics card selects the graphics card mining machine

but mining also need to find a useful mining software, I have been using ha Yu miner mining, easy to use, high income< br />

6. Today's bitcoin mining uses amd graphics cards, which are not very different from ordinary graphics cards. You can also play 3D games on them for design. The hd7850
1g version is the most popular. This model can well balance the mining speed and price
in other words, there are a lot of "mining machine graphics cards" on Taobao, because these graphics cards use less materials under the same core and basically unchanged hash speed, such as recing video memory to improve the performance price ratio (the size of video memory has little to do with the mining speed), which can shorten the time to recover the cost
in short, the graphics card of mining machine is the core of common high-end graphics card + the workmanship of low-end graphics card, or some cheap medium and high-end public graphics card.

7. Generally, amd graphics card has many stream processors, and mining is fast. In those years, 68707850280 (without x) was popular. Now, the new card mining is more valuable than 470d, which is worth 470 yuan. The cost performance ratio and efficiency ratio are more prominent.
