Mining leads to graphics card

1.

mining, in fact, is a problem-solving process. First, we work out a formula with many answers, and then the dealer releases a random answer every other period of time. An answer is the prototype of a virtual coin. We can see who can calculate the answer at this time, and then this person or these people can divide the virtual coin. When the result comes out, we can find the answer, virtual currency is attached with information such as the computer information and problem-solving time of the tester, so that the virtual currency can be "materialized", that is, it has traceability and uniqueness attributes. At this time, the virtual currency is officially g out

using the graphics card is because the computing method of the graphics card is different from that of the CPU. The CPU focuses on logic computing. The graphics card is simple computing, and mining (that is, solving problems) just needs simple computing power. Therefore, mining with the graphics card

bitcoin miner is the equipment for mining bitcoin. The mining equipment can be ordinary computer or USB miner, It can also be a professional ASIC miner

It is true that ordinary computer CPU can mine bitcoin, but because bitcoin mining has formed a huge instry all over the world, it is difficult for indivials to mine bitcoin with ordinary computers. You need to buy expensive and professional bitcoin

ASIC mining machine

and join the bitcoin miners organization to dig bitcoin, that is, to join a mining pool for mining

First of all, CPU and GPU are designed differently for different missions in the computer:

1. CPU is mainly optimized for serial instructions, while GPU is optimized for large-scale parallel computing

Modern multi-core CPUs aim at instruction set parallelism (ILP) and task parallelism (TLP), while GPUs aim at data parallelism (DLP)

3. GPU often has a larger bandwidth of memory, that is, the so-called video memory, so it will also have good performance in high throughput applications

2. There must be damage. First of all, only a card can be used for mining, and N card is boring for mining.
secondly, the computer needs to be running all the time and can't be turned off for mining, which requires a lot of computer. It is harmful for each part to do a lot of calculation for a long time, and it also requires high power supply for the computer
mining can't be powered off, and it needs to be recalculated after power off. Graphics card long time to do a lot of calculations will lead to greatly shorten the life of the graphics card, so their own home, do not recommend mining, mining is not as expensive as electricity

Why use graphics card to mine

compared with CPU, GPU is used for general purpose calculation. So it can stack hundreds of stream processors awesome. Each stream processor is like a small CPU. Although its ability to run complex programs is far from the power of CPU, it can not support many processors, so the actual performance, especially the single precision floating point performance is much stronger than that of CPU. p> However, as we have mentioned before, a card is very suitable for general computing such as virtual currency because it has many stream processors, and the speed of obtaining specific solutions is much higher than that of N card. Therefore, many miners rush to buy a card to calculate virtual currency for profit

of course, with NVIDIA's Pascal graphics card, n card's ability in mining virtual currency is not as different as a card before. So in the current situation that a card is generally out of stock, those mid-range N cards have become the second choice for miners

What are the disadvantages of mine card

finally, I want to talk about why we can't choose mine card when we are shopping for second-hand cards. Because the miners are mining bitcoin, the most important thing is to seek profits. Therefore, the graphics card they use is running and calculating all the time, and its strength is far greater than that of daily game applications. In other words, running such a calculation for one day is equivalent to running a graphics card for one month

in addition, the places where virtual currency is mined are mostly the places where multiple graphics cards gather. Thousands of graphics cards are constantly calculating in a room, and their heat is also quite huge. Miners can not choose the chassis with good heat dissipation conditions like ordinary consumers, so that the heat can be released smoothly. In this way, the graphics cards can still operate for 7 * 24 hours under high temperature conditions, It also deepens its aging degree

the result of doing so is that the graphics cards used for mining are lost prematurely. If you buy these graphics cards, the result will be unstable operation, restart and other things will continue to happen

moreover, at present, manufacturers also have strict requirements on mine cards, such as banning second-hand sales and shortening the shelf life. If users buy these mine card graphics cards, future maintenance will also be a big challenge

4. Mining needs the al precision computing power of graphics card
it has nothing to do with video memory
traditionally, amd card retains the ability of double precision calculation. No castration
n card has been castrated greatly. So the computing power is not as good as card a.

As of October 1, 2020, the state has not issued five element currency, which is illegal

the five elements coin is a virtual circular steel sheet of a pyramid selling group, which is only one circle larger than the ordinary one yuan coin. Its claimed price is 5000 yuan, which is called pure gold

one side is printed with the words of "gold", "wood", "water", "fire" and "Earth", and the other side is printed with a personal portrait and the words of "Zhang Jian's five element coin". According to the MLM personnel, the "five element coin" is a limited edition, with a total of 500 million issued by MLM criminal groups

"five element coin" is operated by a website called "Cloud Data Trade Alliance" without registered address, and its founder is Zhang Jian. In September 2013, the State Administration for Instry and Commerce and the Ministry of Public Security announced ten typical cases of pyramid selling, including the case of Cloud Data Trade Alliance

extended information:

according to Liao Jinsong, leader of Economic Investigation Branch of Chenzhou Public Security Bureau, "five element coin" pyramid scheme was launched by song miqiu at the end of 2016, and members were developed according to the mode of "Y, s and M". Among them, the membership fee for y-class members is 500 yuan, that for S-class members is 2500 yuan, and that for M-class members is 5000 yuan. M-class members are mainly promoted, and members are developed in a al track way to "pull the head" to join

according to the MLM promotion of "five element coin", there are two main benefits of member development offline. One is cash income. For every member who develops, he can get a direct promotion award of 10% of the membership fee; A team with 200 members will win a "BMW Award" of 150000 yuan. In addition, there are virtual currency value-added benefits brought by static value-added, collision award and so on

Liao Jinsong pointed out that in order to avoid legal liability, the pyramid scheme of "five element coin" in the actual promotion process is under the guise of "selling five element gold coins", trying to create the illusion of "selling" gold coins, but its characteristics of "pulling the head", forming the hierarchy in order, and rebate through the hidden layer of "BMW Award" determine the essence of pyramid scheme

6. The algorithmic stable currency usdn solves the most concerned payment efficiency problem in the current market by virtue of the strong performance of NGK, and endows usdn with three mechanisms: currency in circulation, bond voucher and equity index. Through decentralized smart contract, the value of usdn is constant and equal to the dollar price. Even if it fluctuates in a short time, it will quickly return to normal prices under the control of smart contracts.

7. The stream processor of mining graphics card is faster than CPU
so
mining will lead to graphics card price increase

8. Leading to the price increase of medium and high-end graphics cards, such as rx470, 570, 480, 580, R9 380x, R9 390, gtx1050ti, gtx1060, 970, 980, 1070 (TI), 1080 (TI)
