Conversion of mining calculation force

1. Lightcoin is 1.8g. The computing power of the whole network is only 8600gh / s, and 1080ti graphics card occupies 1 / 4700
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.

2. At present, only a few algorithms of virtual currency are meaningful, such as XPM (prime currency, used to solve prime numbers), GRC (Greider currency, used for scientific operation), etc. I have been using CPU to dig XPM, although my income is limited. In fact, these currencies also have the excellent properties of bitcoin, but they are not favored by most virtual currency lovers. The price is very low, which is really distressing.

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

4. From cheap electricity to centralized mining, China's resources and environment provide bitcoin miners with many advantages. In recent years, bitcoin miners have used cheap electricity to expand their business in coal rich regions such as Xinjiang and Inner Mongolia, which are home to the founders of some of the world's leading mining companies

with the rising price of bitcoin, more and more people join the bitcoin mining business. Accordingly, mining consumes more and more energy. Obviously, our government is also aware of this

according to the requirements of the document, regulators require local governments to take measures related to electricity price, land use, tax and environmental protection to guide bitcoin miners to withdraw from the business. According to foreign media reports, regulatory authorities are mainly concerned about the money laundering and financial risks involved in the shutdown policy, but excessive power consumption is also a factor that can not be ignored. In principle, bitcoin mining consumes a lot of power because every time a new bitcoin is proced, it needs to solve the complex mathematical problems through the encryption process performed by a high-performance computer. Mining calculation process is used to verify bitcoin transactions in the blockchain to ensure security, but the disadvantage is that it consumes a lot of energy.

5. As the name suggests, the mine calculation card is a graphics card used for mining. More strictly speaking, it is a graphics card used for mining with high load for a long time. The graphics card used in mining usually works at full load 24 hours a day for several months. In this way, PCB and electronic components will accelerate aging, affecting the life of components. Not counting the rest time of the graphics card, even if we play the game for 8 hours a day, the life of the mine card is only one third of that of the normal graphics card. It can be said that the general life of the mine card is only a few months.

Before the main network of IPFs filecoin was launched, the specific mining yield could not be calculated effectively and accurately, and the mining computing power of filecoin became a complex composed of bandwidth, hard disk space, network coverage and other factors

what the data storage market needs to contribute is hard disk storage space. The more hard disk space, the higher the mining capacity; Provide network bandwidth and get fil by mining bandwidth resources; The mining machine developed by interstellar continent based on the technical points disclosed in IPFs and filecoin white paper has more advantages in computing power

when building bitcoin, Nakamoto wants bitcoin to be a decentralized currency, not only for use and trading, but also for mining. But it backfired. With the increasing value of cryptocurrency such as bitcoin, mining has become an instry. The competition is more and more fierce, and the pursuit of mining computing power is higher and higher. Therefore, from ordinary computer mining, ASIC mining machine and GPU mining machine have evolved

the algorithm of ASIC mining machine is almost sha256, while the algorithm of GPU mining is different. For example, the algorithm of BTG is equihash, and the algorithm of BCD is optimized x13. Although it is not absolute, it can be simply considered that the currency of sha256 algorithm is generally mined by ASIC mining machine. Other algorithms are basically using GPU miner. There are also exceptions. Scrypt's Leyte coin used to be mined by GPU miner, but later scrypt's algorithm was also conquered by ASIC chips, such as ant miner L3 +, which is the ASIC miner used to dig Leyte coin

ASIC miner refers to the miner that uses ASIC chip as the core of computing power. ASIC is the abbreviation of application specific integrated circuit, which is a kind of electronic circuit (chip) specially designed for a specific purpose. Some mining machinery factories have designed ASIC chips specially for computing the sha256 algorithm of bitcoin, and the mining machinery using them is ASIC mining machinery. Because ASIC chip is only built for specific computing, its efficiency can be much higher than that of CPU. For example, the current mainstream ant miner S9 is ASIC miner, which uses 189 ASIC chips, the computing power reaches 13.5th/s, and the power consumption is only 1350W. As a comparison, the computing power of gtx1080ti, the flagship computer graphics card, will not exceed 60mh / s even if it is optimized well. The difference is tens of thousands of times

GPU miner refers to the miner that uses GPU graphics card as the core of computing power. Cryptocurrencies such as Ethereum, bitcoin and diamond use graphics algorithms, so the speed of computing with graphics card will be the highest. Compared with ASIC miner, GPU miner is more well-known, because it is a computer with enhanced graphics card configuration

the purpose of GPU miner is to make money, so we should pursue the power consumption ratio and maximum profit, so we should pay attention to the cost performance. Generally, the medium and high-end positioning graphics cards, such as AMD rx560 and rx570, have high power consumption ratio, which is a good choice for GPU miner. While flagship cards such as gtx1080ti and AMD vega64 have the strongest single card performance, they are not cost-effective in terms of price and power consumption

in addition, the ASIC miner also has some exotic procts, such as the USB miner of burning cat, which is slightly larger than the U disk, and the power consumption is only 2.25w, which is the smallest bitcoin miner at present

the above quoted digcoin.com - "Introction to mining machinery classification" has many professional terms. I hope it can help you, thank you

8. In order to know what mining is calculating, we must first know the essence of bitcoin and its proction process. Bitcoin is a network-based electronic currency, which is actually a string of codes of the Internet, calculated by algorithms. Mining is the process of completing the algorithm and the only way to proce bitcoin. And because of the algorithm, there are only 21 million bitcoins
1. Mining can not only proce bitcoin, but also guarantee transaction information
similarly, a mathematical system contains 21 million mathematical problems, so we need to constantly seek the special solution of each mathematical problem through a huge amount of calculation. In addition, the special solution is unique
mining can not only increase the supply of bitcoin money, but also protect the security of bitcoin transactions and prevent fraulent transactions. In terms of process, bitcoin network is a point-to-point payment system, and anyone can trade through the transaction program
in order to ensure that the transaction process is truthfully recorded, the role of "miner" is required to be responsible for recording bitcoin transaction information. The time interval is 10 minutes. The best recorded transaction records among miners will be packaged and stored in a new block, and the corresponding miners will also receive a certain amount of bitcoin rewards
2. The mining process is extremely complex, which is beyond human power
the specific process is as follows. When a miner listens to the transaction, he will first verify the transaction information. The verified transactions will be recorded by miners and stored in their own database. There may be thousands of miners in the world doing the same thing, but every ten minutes, only one miner has the right to create a new block, so that the transaction information recorded by himself can be recognized and stored permanently
next, miners need to fight for the right to keep accounts. This is a competition of computing power. The core of this competition is to use computers to complete a large number of calculation tasks and find a super difficult random number. This random number is the special solution of the equation mentioned in the first paragraph. The miner who calculates the correct random number first wins. According to the rules of the game, the probability of a miner getting the accounting right is directly proportional to the proportion of his computing power in the total computing power of the whole network. In other words, the probability of finding the random number is equivalent to throwing out 100 million dice, and the total number of dice is less than 150 million. Therefore, mining requires a large number of computers, installation of specific algorithm software, repeated operation day and night, not human
3. Bitcoin mining is actually "villagers' bookkeeping"
maybe some netizens still don't understand, let's take an example. In a village, the villagers often borrow money from each other, even if they write a written document, there is a risk of default. Then, every time there is a loan behavior in the village, we will use the village trumpet to inform everyone that all the villagers (miners) will record all the transaction records in their own account books.
