Mining power of graphics card
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
21.5 * 3600 seconds * 24 hours = 1857600 M / day
1857600 / 1024 / 1024 = 1.7715 T / day
a t of computing power / day can dig bitcoin worth 4.03 yuan
1.7715 * 4.03 = 7.14 yuan / day
since 2017, bitcoin has reached new heights. Yesterday (May 23), the value of bitcoin broke through the ￥ 16000 mark, hyping virtual currency, becoming a matter that the general public can participate in, And a little bit of technical level, both fried money, but also began to have the technical content of mining
as we all know, virtual currency has a numerical peak, the more difficult it is to dig. In fact, it's hard to judge whether to lose money or not if we continue to dig. Therefore, in the end how to dig, dig what can be the fastest back to this, this paper studies the above two core issues based on the current market situation
eth is only 32mh / s, 1070 has 40mh / s. Many people say that 1080ti can't pull up the computing power because of the high delay of gddr5x video memory. As expected, it's better to mine with a card. People on the Internet say that 480 can have 65mh / S computing power
Zec, 724sol / s, nearly three 1060 3G, the total price is more expensive than three 1060 2K soft coins. However, compared with the short supply a-card rx4808g, the price of three cards is less than 5K, and the computing power is 900 + sol / s, but it's useless if there is a price but no market
it's too wasteful to use this card for mining. It's just for fun and can't afford to hurt.
You can refer to the following, according to some commonly used graphics cards in the Internet bar market, sort out the price and calculation power of a related graphics card, as well as the expected return to the current period, It can be used as a reference:

Video card (graphics card) full name display interface card, also known as display adapter, is the most basic configuration of computer, one of the most important accessories. As an important part of the computer host, the graphics card is the equipment of digital to analog signal conversion, and it undertakes the task of output display graphics
the graphics card is connected to the main board of the computer, which converts the digital signal of the computer into an analog signal for the display. At the same time, the graphics card still has the ability of image processing, which can help the CPU work and improve the overall running speed. For those engaged in professional graphic design, graphics card is very important. Civil and military graphics chip suppliers mainly include amd (ultra micro semiconctor) and NVIDIA (NVIDIA). Today's TOP500 computer, including graphics card computing core. In scientific computing, graphics card is called display accelerator
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
In short, mining is the use of chips for a random number related calculation, get the answer in exchange for a virtual currency. 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
In his paper, Nakamoto stated:"in the absence of central authority, it not only encourages miners to support bitcoin network, but also enables bitcoin's currency circulation system to have the initial source of money injection."
Nakamoto compares the generation of bitcoin by consuming CPU power and time to the consumption of resources by gold mines to inject gold into the economy. Bitcoin mining and node software mainly initiates zero knowledge proof and verification transactions through peer-to-peer network, digital signature and interactive proof system
each network node concts broadcast transactions to the network. After these broadcast transactions are verified by miners (computers on the network), miners can use their own work proof results to express their confirmation. The confirmed transactions will be packaged into data blocks, and the data blocks will form a continuous data block chain
Nakamoto himself designed the first version of bitcoin mining program, which was later developed into the first generation of widely used mining software bitcoin, which was popular from 2009 to mid-2010
each bitcoin node will collect all the unconfirmed transactions and gather them into a data block. The miner node will add a random adjustment number and calculate the SHA-256 hash value of the previous data block. The mining node tries again and again until it finds the random adjustment number so that the hash value is lower than a specific target
extended data
at the earliest, bitcoin miners were mining through Intel or AMD CPU procts. But because mining is a computing intensive application, and with the continuous improvement of mining number and equipment performance, the difficulty graally increases, now using CPU mining has no profit or even loss
as of 2012, since the first quarter of 2013, miners graally began to use GPU or FPGA and other mining equipment [5]. At the same time, a large number of ASIC devices were launched in mid 2013
since July 2013, the computing power of the whole network has shown a straight-line rise e to the large number of ASIC equipment put into operation. Based on the average computing power in July 2013, all CPU mining equipment has been unable to generate positive revenue, and FPGA equipment is close to no revenue
according to the estimation of average computing power in September 2013, the existing small ASIC mining equipment developed for indivials will also be close to no positive revenue in the next 1-2 months. A large amount of computing power is monopolized by cluster ASIC mining equipment with 5 th ash / s or more. Because of no profit, indivial mining is almost squeezed out of mining groups. Some bitcoin miners have raised funds to build machine rooms and install a large number of mining equipment in places where low-cost electricity can be obtained
in order to save the cost of mining, some bitcoin miners make mining programs into malicious programs to infect other people's computers on the network to mine for themselves
The first step in setting up mining equipment is to choose the right hardware. This article will focus on GPU (graphics card) mining, of course, you can use CPU or ASIC equipment mining. Amd graphics card architecture is very beneficial to mining. NVIDIA card is not suitable for mining because of its low hash rate. The best NVIDIA graphics cards are less than 0.5 megahash. Notebook Hardware mining is not as good as NVIDIA card, which is a bad option for mining. You need to use a desktop system for mining. There is a desktop system to ensure adequate cooling of the hardware
the graphics card or card needs to be able to match the motherboard, and the power supply must have enough PCI-E connectors. Before determining the graphics card, pay attention to these. In order for the system to cool down sufficiently, you need to remove the cover of the chassis in order to get better heat dissipation. This is what people call "open air rig.". If you can aim the system at a fan or air conditioner, you can make the device cooler when it's running, thus extending its life and keeping it efficient
a card, that is to say, it depends on the frequency and SP
