Pyrograph card mining
Through a specific program and algorithm, using the computer graphics card calculation rate, a large number of calculations are carried out in the selected mine pool to generate data packets
Computer graphics card mining: refers to the process of mining bitcoin with computer graphics card
video card mining is a formula with many answers. Users download the decoder from personal computer and then run a specific algorithm to decode it. After communicating with the remote server, they can get the corresponding bitcoin. The more powerful the graphics card is, the faster the decoding speed is, and the faster bitcoin will be g. It's also called mining

extended information:
1. Introction to bitcoin mining machine:
bitcoin mining machine is a computer used to earn bitcoin. This kind of computer generally has professional mining chips, and works in the way of burning graphics card, which consumes a lot of power
2. How to use bitcoin mining machine:
download the special bitcoin computing tools, register various cooperation websites, fill the registered user name and password into the computing program, and then click the operation to officially start

Generally, there are professional graphics cards to mine, and the mine is actually bitcoin. Users download the mining software from the computer and then run a specific algorithm. After communicating with the remote server, they can get the corresponding bitcoin. Most of them work by burning the graphics card, so the power consumption is large
the graphics cards and mine cards are usually ATI chips. The bitcoin market is not good, so the miners take out their mining cards and sell them as second-hand
what is mining
to put it simply, mining is to use the chip to perform a calculation related to the random number, and get the answer in exchange for a virtual coin. 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. It's possible that one chip will find the answer in the next second, or ten chips won't find the answer in a week. The more chips compute at the same time, the easier it is to find the answer, and the mining machine with built-in multi chips appears. And a number of mining machines to form a "mine" at the same time mining is to improve efficiency. In the mine pool, multiple "self-employed" join an organization to mine together. No matter who finds the answer and digs out the virtual coin, everyone gets the corresponding reward according to the calculation ability of contribution. This way can make the income of "self-employed" more stable
relationship between mining and graphics card
the stronger the computing power of ant miner, the easier it is to dig out virtual coins. Accordingly, when the more virtual coins are g out, the difficulty of mining will be increased accordingly, so as to control the yield of virtual coins. The virtual currency is not unlimited. The total number of bitcoin is 84 million
It will accelerate the aging of graphics card
in order to make money, the graphics card works continuously for 7x24 hours and runs at full load. Some people will overclock the graphics card in order to earn more money. The general home game graphics card is not designed for this kind of use environment at all. Long time full load operation will lead to accelerated aging of the graphics card, Generally, the life of the graphics card used for half a year of mining is longer than that of the normal use of the players for three years, so now the major brands have made strict restrictions on the quality assurance of the cards

principles of computer Mining:
starting from the essence of bitcoin, the essence of bitcoin is actually the special solution generated by a bunch of complex algorithms. A special solution is one of the finite solutions of a system of equations. Every particular solution can solve the equation and is unique. In the metaphor of banknotes, bitcoin is the number of the top word of a banknote. If you know the number of the top word of a banknote, you will have the banknote
and the process of mining is to constantly seek the special solutions of the equations through huge amount of calculation. The equations are designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million
to mine bitcoin, you can download the special bitcoin computing tools, register various cooperation websites, fill the registered user name and password into the computing program, and then click the operation to officially start. After completing the installation of bitcoin client, you can directly obtain a bitcoin address. When others pay, you only need to paste the address to others, and you can pay through the same client
after installing the bitcoin client, it will assign a private key and a public key. You need to back up the wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, personal bitcoin will be completely lost
1. CPU is mainly optimized for serial instructions, while GPU is optimized for massively parallel operations
2. Modern multi-core CPU aims at instruction set parallelism (ILP) and task parallelism (TLP), while GPU is 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
the CPU needs strong generality to deal with various data types, and at the same time, it also needs logical judgment, and it will introce a lot of branch jump and interrupt processing. All these make the internal structure of CPU extremely complex. GPU is faced with highly unified, interdependent large-scale data and pure computing environment without interruption. GPU uses a large number of computing units and ultra long pipeline, but it only has very simple control logic and saves cache. The CPU not only occupies a lot of space by cache, but also has complex control logic and many optimization circuits. So unlike CPU, GPU is good at large-scale concurrent computing, which is suitable for password cracking
in short, CPU is a general-purpose operation. In short, it means brainless calculation and violent calculation. Whether it's 100 children sharing apples or simulating the earth, it can be decomposed into the most basic calculation of 1 + 1 = 2. GPU is specially designed to deal with high-order mathematical algorithms, such as calculating the relative positions of light source, object, viewpoint and shadow, which requires trigonometric functions to be piled up. The bitcoin digger uses SHA-256, a secure hash function invented by the US National Security Agency, which is generally used for password encryption and decryption. This algorithm can perform a large number of 32-bit integer right-rotate operations, which is very suitable for GPU which is good at large-scale concurrent computing and password cracking.
