Mining of abandoned graphics card
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
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
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
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
in short, mining is to use the chip to carry out 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
take a popular example:
I write a string of numbers on a piece of paper and give some hints. Whoever guesses correctly will be given a bonus (mining)
smart people can make more guesses (calculation ability)
some people pay money to invite many people to come back and guess together (mining)
some people call everyone together to guess, no matter who guesses, Distribute the bonus (mine pool) according to the proportion of guessing times of each person
the rest is too long, you can search by yourself...
"Human observation" is a variety show proced by TBS television station in Japan. It is hosted by black menaz and broadcasted at 8 p.m. every Thursday. The program hides the camera in a corner, and each episode sets up something that is difficult or impossible to happen in daily life
NVIDIA recently (18-8-17) began to focus on the development of mining business. Amd may still have a certain market share because of its greater dependence on mining, but it will not rule out being replaced by professional mining machines and chips in the future.
1. Price
you may know that intensive mining is quite expensive because it requires a lot of resources. The power consumption is huge, and with everyone's participation, the difficulty of mining will increase, which means that a lot of computing power is needed
as the cost increases, you should remember that the price of GPU for mining should be one of your top considerations
nowadays, most mining equipment is created with several GPUs, so that they can make more (Network) contributions and make more money (tokens). The cost of each GPU may vary, depending on how much you are willing and able to spend, but you can expect the price of each GPU to range from $150 to $1300
your best choice is to buy those graphics cards with moderate price. In this way, you won't pay too much, but you can still get a decent proct, and it's worth your time to mine
2. Power consumption
as mentioned above, power consumption is a big problem. The greater the power consumption, the greater the heat generated in the mining process. But these two problems can be controlled as long as high wattage GPU is not used
if you don't want to deal with these problems, choose a low or medium wattage GPU, or pay extra for advanced cooling technology. However, you should remember that this will mean that your hash rate will be reced, so your profit will not be so high
3. Hash rate
when we discuss hash rate, it is also an important factor, which is determined by the execution speed of GPU, or mining speed. The type of GPU you use and the algorithm your token uses are also important factors
therefore, if you do not have a specific currency, perhaps the best thing is to buy a GPU with a comprehensive hash rate, so that it can play a role in a wider range of hash algorithms
in this way, you don't have to dig one coin, but have the opportunity to dig another
4. Warranty is also something you should pay attention to. However, it should be noted that mining will not damage your GPU more than games or other high-performance tasks
however, as long as you choose to mine, your GPU must perform under continuous load, so for the sake of safety, it is recommended to buy a 2-year warranty. After all, if something happens, the money will be wasted
5. Overclocking performance
overclocking is also something you need to study, because many GPUs can adjust to faster performance, sometimes even 20-30% faster
this can make the graphics card more efficient, help you make more contributions when solving each block, and then ensure more sharing. Considering this, it depends on the overclocking performance of GPU. When it is forced to the limit, it is necessary to choose the one that can do better
of course, there are other minor factors that can also affect your performance as a miner, but these are the main things to pay attention to.
