What's the meaning of the mining of the graphics card seal
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
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
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
for mining machines, the most important thing is the graphics card. Generally, you can choose the most basic motherboard that supports 6 graphics cards, and later you can choose the more complex motherboard that supports more than 12 graphics cards. The specific suggestions are as follows:
1. CPU - CPU can choose the most basic and cheap CPU, as long as you can bring the system up normally, Generally, you can choose Intel's g3900 CPU with a unit price of about 200 yuan< Operating system is too laggy. If you use 6 graphics cards, you need at least 4G of memory. If you are 12 graphics cards, the windows operating system needs at least 8g of the memory. Otherwise, the system will be very stuck and then can not work normally. The Linux operation system can be 4G memory. < br > />2.
3. Motherboard - it is recommended for novices to directly choose the special mining motherboard of Yingtai series. The models are tb250 BTC with 6 card slots and tb250 btcpro with 12 card slots, as well as H81 series motherboard of Huaqing
4. Hard disk - SSD hard disk is needed for hard disk, because the reading speed is fast, and virtual memory needs to be set. SSD hard disk can improve some performance theoretically. If you use Windows system, you need at least 64GB, and Linux system can use 16GB
5. Operating system for windows, it is recommended that win10 system, corresponding to NVIDIA series and AMD Series graphics cards, can recognize up to 8 cards respectively. If the motherboard of 12 cards needs N cards and a cards to be mixed, then we can make full use of the motherboard graphics card slot
6. Graphics card - the mainstream mining graphics card models are amd Series graphics cards rx470, rx570, rx580, NVIDIA Series graphics cards gtx1060, gtx1070 and so on. It is recommended to choose 4G or more memory, and 8g is the best.
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. 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
computers have professional mining chips, and most of them work 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
extended data
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
Through the operation of the processor in the graphics card, the problem can be solved and the reward can be obtained. Generally, they are digital currencies, such as bitcoin, lettercoin and so on. The difficulty of answering questions is different, so are the rewards, and the calculation data. And this kind of mining needs 24-hour non-stop calculation data, so the loss of graphics card is great
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

the difference between mine card and ordinary graphics card
the most essential difference between special mine card and ordinary graphics card is whether there is a display interface, some have no or only one interface, and other mainstream HDMI, DVI, DP HD interfaces have been castrated, so they can only be used for mining, not suitable for playing games
the special mine card is only equipped with PCI-E 1.1 because it only aims at the general calculation application of mining with low bus bandwidth requirements × 16 interface, and the ordinary game graphics card is equipped with a higher specification of the mainstream pci-e2.0 / 3.0 specification
to see if the core is yellow, some parts of the new card will be light yellow, but at that time, the color of the protective paint is yellow, while the core yellow of the mine card is yellow and burnt yellow caused by high-frequency use of heat for a long time
