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. Now we have to use a miner to dig the coins

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 software, from the programming principle, is about large-scale parallel computing
there are many stream processors in GPU of graphics card. For example, the old HD5770 has 800 stream processors, which is equivalent to 800 computing cores. In recent years, the mainstream high-end graphics card has more built-in stream processors and more powerful computing performance. Using GPU for mining operation, the stream processor is used for parallel operation, and the mining program also optimizes the GPU parallel operation, so the operation efficiency is particularly high, and the efficiency of bitcoin mining has been greatly improved
the number of CPU cores is relatively small. At present, the number of the most powerful mainstream desktop processor cores is no more than 10 or 20 (many are logic cores virtualized by hyper threading technology), and the parallel computing power is far less than that of GPU.
5. If you want to mine, what are the best independent graphics cards to use? Gtx1060 3G and 6G graphics cards, rx5704g, rx5808g graphics cards. These four graphics cards are currently the most used ones in mining, with good computing power and low price,

Starting from the essence of bitcoin, the essence of bitcoin is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique

why use graphics card to mine

compared with the complex computing of CPU, GPU used by graphics card is used for general computing. 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>

the actions in bitcoin can be considered as the use of graphics card to do continuous general computing, and the computational complexity is relatively low and quite repetitive. The stream processor used by graphics card is just suitable for such an algorithm. It's like constantly solving equations. The graphics card is 2000 middle school students, while the CPU is 8 math doctors. Although the mathematical knowledge of the doctor of mathematics is far more than that of the middle school students, the speed of solving medium-sized equations such as virtual currency is certainly not as fast as that of 2000 middle school students

so we used graphics card to mine virtual currency at the beginning. After that, someone developed a specific algorithm to make the stream processor of the graphics card greatly strengthen the virtual currency solution, which is the origin of the mining machine

7. Bitcoin is a member of the virtual currency. The data is calculated by a specific algorithm, and the total number of data is fixed. Therefore, bitcoin is less and less g, and it is more and more difficult to dig. Recently, bitcoin's rise is quite high, which has spawned a group of new miners to enter the pit. It can only be said that they are waiting for the mine disaster. Amd graphics card is generally preferred in mining, because in recent generations, n card tends to simplify the basic floating-point operation and improve the utilization rate of the architecture to the core, while a card has always liked the heap stream processor with crazy heap parameters, just what mining needs is the basic double precision floating-point operation ability, so a card is generally preferred in mining.
8. It's a trade secret. How can you send it to the Internet casually? It's suggested that you go directly to the shopping mall to do field investigation, and then analyze the short-term data according to the investigation to infer the data of one year. Of course, you can go directly to the person in charge of the shopping mall to ask, but basically people won't tell you
I have done a similar paper assignment before, which is about audio-visual procts. I went to a lot of places to ask questions, but they either didn't want to answer or gave me very general data
9. The actions in bitcoin can be regarded as the use of graphics card to do continuous general computing, and the computational complexity is relatively low and quite repetitive. The stream processor used by graphics card is just suitable for such an algorithm. It's like constantly solving equations. The graphics card is 2000 middle school students, while the CPU is 8 math doctors. Although the mathematical knowledge of the doctor of mathematics is far more than that of the middle school students, the speed of solving medium-sized equations such as virtual currency is certainly not as fast as that of 2000 middle school students. Therefore, the more graphics cards, the more operations.
10. Mining machine is a combination of mining graphics card machine, computing power is greater, belongs to the professional mining equipment, civil computer graphics card can also dig, but between their own computing power is basically a type of fun
