What's the meaning of mining computing power
"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 />
In 2009, bencong invented bitcoin, and set that there are only 21 million bitcoins. By participating in the proction of blocks and providing proof of work (POW), he can get the reward of bitcoin network. This process is mining
the concept of "mining" comes from the existing concepts in our real economic life, such as gold mining and silver mining. Because minerals are valuable, it drives people to pay labor to dig
another important point of bitcoin mining is that the miners who participate in mining recognize the value of bitcoin, and some of them are willing to spend money in the bitcoin market. Therefore, the mining of bitcoin is meaningful

currency characteristics of bitcoin
1, decentralized
bitcoin is the first distributed virtual currency, and the whole network is composed of users without central bank. Decentralization is the guarantee of bitcoin's security and freedom
2, bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin
3, exclusive ownership
controlling bitcoin requires a private key, which can be stored in any storage medium in isolation. No one can get it except the user himself
4, low transaction cost
bitcoin can be remitted free of charge, but in the end, about 1 bitfen transaction fee will be charged for each transaction to ensure faster transaction execution
5, no hidden cost
as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay
6, cross platform mining
users can explore the computing power of different hardware on many platforms
Mining: that is, bitcoin mining, is a process of using computer hardware to calculate the location of bitcoin and obtain it
Mining is the use of bitcoin mining machine, which is used to earn bitcoin
one of the ways to get bitcoin is that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server
bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce
mining is actually a competition of performance and equipment. The mining machine composed of many graphics cards, even if it's only hd6770, can surpass the single graphics card of most users
and this is not the most terrible. Some mining machines are made up of more such graphics card arrays. When dozens or even hundreds of graphics cards come together, the graphics card itself costs money. Considering the hardware price and other costs, there is a considerable expenditure in mining
bitcoin mining process:
1. To find the ore pool
to start mining, there must be a ore pool with convenient operation and stable output. Its function is to subdivide the data packets for each terminal, and pay the corresponding amount of bitcoin according to the proportion of the data packets calculated by the terminal through precise algorithm
2. Download bitcoin miner (software)
in fact, there are many kinds of this miner, you can go to the official website to download
3. Setting mining software is a green software. After installation, we can set the language first to facilitate further setting. Next, you need to set the server, user name, password, equipment and so on. Generally, the server chooses a better network from BTC guide series, and the user name and password are set by ourselves before
4, bitcoin mining start
when we confirm that all settings are correct, click the "start mining" button to start bitcoin mining, and then the graphics card will soon enter the full speed running state, the temperature and fan speed will increase, you can monitor the state through gpu-z or graphics card driver
2. Digital currency is a kind of unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of specific virtual communities. The European Banking authority defines virtual currency as a digital representation of value, which is not issued by the central bank or authorities, nor linked with legal currency. However, because it is accepted by the public, it can be used as a means of payment, or it can be transferred, stored or traded in electronic form

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
