What does the headmaster mean by mining
"Graphics card mining" is actually to use the graphics card to dig bitcoin, so that the graphics card can work with high load, and the eliminated ones will become mine cards. Generally, the core PC board on the back of mine cards is seriously discolored< br />
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

Mining is a nickname for the exploration method of acquiring bitcoin. Because of its working principle is very similar to mining minerals, so named. In addition, bitcoin explorers who do mining work are also known as miners
bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system
bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network can get a qualified answer about every 10 minutes
then the bitcoin network will generate a certain amount of bitcoin as a reward to reward the person who gets the answer
extended data:
to be a miner, just "mine" bitcoin and search for 64 bit numbers by computer. By repeatedly decrypting with a computer, it competes with other gold miners to provide the number needed for the bitcoin network
if the computer can successfully create a set of numbers, it will get 25 bitcoins. Bitcoin is decentralized. It needs to create a fixed number of bitcoins per unit of computing time. It can get 25 bitcoins every 10 minutes
by 2140, the upper limit of bitcoin in circulation will reach 21 million. In other words, bitcoin system can be self-sufficient, which can be translated into coding to resist inflation and prevent others from sabotaging< br />
ancient mining can be traced back to the selection of stone materials in the stone age. Later, with the rise of the metallurgical instry, mining, mineral processing technology has graally developed. This paper introces the ancient Chinese open-pit mining, underground mining, roadway support, rock fragmentation, roadway ventilation, lighting, drainage, transportation, mineral processing and other aspects< There are many surface outcrops, slope deposits or resial deposits in open-pit mining of various metal veins or orebodies, so open-pit mining has become an important mining method in ancient times. Open pit mining can be divided into excavation method and reclamation method
2. Mining is the synonym of accumulated income for activities in bitcoin
mining is brought out by the recent popularity of bitcoin. As a virtual currency, bitcoin can be exchanged for real currency. One of the ways to get bitcoin on the Internet is to participate in related activities every day. These activities, like mining in online games, need to slowly accumulate wealth in exchange for bitcoin.
Bitcoin mining is a process that uses computer hardware to calculate the location of bitcoin and obtain it
mining is an incentive process to record data in the bitcoin system. In the bitcoin system, indivial users have the right to pack blocks after calculating a specific hash value by using CPU or GPU to hash
and in order to reward this user for packing blocks, the system will give a certain amount of bitcoin as reward. Because this process is very similar to "mining" in real life, most people call this process mining. In addition to bitcoin, other electronic virtual currencies can also be obtained through mining rewards, such as Ethereum, Monroe and so on
extended data:
mining risk:
1, currency security
the withdrawal of bitcoin requires hundreds of keys, and most people will record this long string of numbers on the computer, but frequent problems such as hard disk damage will make the key permanently lost, which also leads to the loss of bitcoin
2, system risk
system risk is very common in bitcoin, and the most common one is bifurcation. Bifurcation will lead to a drop in currency price and a sharp drop in mining income. However, many cases show that the forking will benefit the miners, and the forked competitive currency also needs the miners' computing power to complete the minting and trading process. In order to win more miners, the competitive currency will provide more block rewards and handling charges to attract miners. Risk makes miners
Because bitcoin is valuable now. If you want to get this kind of virtual currency, you can "dig" on the Internet in addition to trading. The so-called "dig" is to use the graphics card to download the decoder on the website of the bitcoin distribution center to decode, and then you can get bitcoin. The stronger the graphics card is, the faster the decoding speed is, the faster the bitcoin will be g. It's also called mining. So there are a lot of people wantonly purchase graphics card mining, so graphics card will soar
mining is actually using a special customized computer to run a set of special algorithms to decrypt the encryption algorithm of virtual currency For example, this currency has a series of codes. People "guess" the code through the algorithm. If they guess all the codes correctly, they can get a complete virtual currency. If they guess one point correctly, they can get a part of it, such as "0.00035637 bitcoins". Yes, virtual currency can be divided. It is not possible to dig a complete bitcoin at one time. The bitcoin g is a string of characters.)
the reason for mining with graphics card is that the algorithm of decrypting bitcoin is actually very simple, which is not a high-level operation, but it has a lot of amount, and the graphics chip is more suitable for this than the CPU chip For example, 1 + 1 =? 2+2= This kind of algorithm seems simple to you, but if I tell you this kind of simple algorithm, there are 100 million in total?! Would you like to try to figure it out? I believe you can figure it out, but it's just a long time)
(CPU chips and graphics chips have a huge number of transistors, which are responsible for computing. The difference is that the transistors of CPU chips are divided into many parts, which can deal with all kinds of task instructions. When running simple operations, only a part of the transistors are working, The others are on standby, because other transistors are not responsible for this task. They can calculate, even if they are relatively slow, but they will still consume the same power, resulting in a low cost-effectiveness ratio.
(graphics chips are different. In fact, most of their work is "crazy rendering triangles". What's a crazy method? Render 1 billion triangles in one second!!! This work is relatively simple, but the amount is very large, and there is a high requirement for the speed of "rendering", so the graphics chip can make its transistors all move when it is designed, so as to achieve the purpose of "rendering" more triangles in the shortest time! This happens to be very similar to the process of decrypting bitcoin, so most of them use graphics cards to mine. This doesn't mean that CPU can't mine. People can mine with their heads. Do you believe it? It's just very slow, and the value of the bitcoin is not enough to pay for your electricity and meals)
mining can't "lie down and make money", because a qualified miner's price ranges from tens of thousands to hundreds of thousands according to its computing power. Because it consumes a lot of electricity, the cost of mining is not only to buy a miner, but also to include the electricity! Moreover, the mining machine needs good heat dissipation and daily maintenance to extend the life of the hardware as much as possible, so if you dig the mine, you will not have much leisure. In addition, the number of virtual currencies is limited, it is more and more difficult to dig, and the stability of the value is poor. Maybe you invest 10 million yuan to build a mine, and a wave of collapse will occur. You have been frozen for 10 million minutes
