What does it mean to buy graphics card mining
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
A graphics card, a software that can earn bitcoin. Inject new bitcoin (data hashing) into the whole bitcoin market, and then the market will have a certain incentive mechanism (allocate bitcoin to you in proportion). Because if you don't get it, no one will do it, just like your computer is a miner, and bitcoin is the reward
Simply put, it is to use your graphics card to work for others in your spare time in exchange for compensation. Only AMD's graphics card is suitable
graphics card mining to make money:
1. Determine the virtual currency to be mined
Mining, in fact, is to use graphics card to dig bitcoin
bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million
bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items
The so-called mine card is bitcoin mining graphics card. Because of the overload operation of the mine card, the life of the graphics card is shortened and the aging is serious
the bitcoin mining machine is the computer used to earn bitcoin. This kind of computer generally has professional mining chips, and works by installing a large number of graphics cards, which consumes a lot of power. One of the ways to get bitcoin is to download mining software and then run specific algorithm to communicate with remote server to get corresponding bitcoin
mining is actually a competition of performance and equipment. Some mining machines are made up of more graphics card arrays. With dozens or even hundreds of graphics cards, the cost of hardware and other costs is very high, and there is a considerable expenditure in mining

the discrimination method of mine card, Even the plastic plug is on it, so pay a little attention to it
The second is to look at the capacitance and other components on the graphics card. In essence, the graphics card is a combination of various chips and electronic components on the PCB board. In the process of overclocking and long-term use, the mine card will cause many components to turn yellow. If you carefully observe, the video memory chip will be black in yellow phenomenon, and then according to the time of the video card to judge, this will be more secure3. There is also the mark of screw. Only a few mine cards are installed with screws. If the screw hole position of the second-hand card purchased by yourself is very new or even has no mark, you should pay attention to it
Graphics card mining is a process of increasing the bitcoin money supply
the reason why the graphics card is used is that mining is actually a competition of performance and equipment. The mining machine is composed of graphics card array.

bitcoin does not rely on the issuance of specific monetary institutions, and is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction
the bitcoin system is composed of users (users control the wallet through the key), transactions (transactions will be broadcast to the whole bitcoin network) and miners (the blockchain is generated by competitive computing to reach a consensus at each node, and the blockchain is a distributed public authoritative account book, including all transactions in the bitcoin network)
bitcoin miners manage the bitcoin network by solving the problem of workload proof mechanism with certain workload - confirming transactions and preventing double payment. Because hash operation is irreversible, it is very difficult to find the random adjustment number of matching requirements, which requires a continuous trial and error process that can predict the total number of times
when a node finds the solution matching the requirements, it can broadcast its results to the whole network. Other nodes can receive the new data block and check whether it matches the rule. If other nodes find that they really meet the requirements (the operation target required by bitcoin) by calculating the hash value, then the data block is valid, and other nodes will accept the data block
The mine card of graphics card is the graphics card used by bitcoin mining machine
Mining card is a graphics card that is specially used for general calculation to earn network currency "bitcoin". Bitcoin can be proced with specific programs, and then sold to people in need to be able to exchange real money, or mining for short
because this program needs a lot of repeated calculations, it is more efficient to use a card with more sp. Because of the full load operation all year round, there are many uncertain factors in the mining card
extended data:
mining is actually a competition of performance and equipment. The mining machine composed of many graphics cards, even if it is only hd6770, the computing power after "group" 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
in fact, there are many kinds of mining devices. Guiminer, which is small and easy to use, is recommended. It can support CPU, oepncl, CUDA and other computing modes
in this way, devices including CPU and graphics card can achieve the maximum performance, and then acquire bitcoin more quickly
resources: Network - bitcoin mining machine
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
