ASIC mining algorithm

1.

mining is a nickname for the exploration method of acquiring bitcoin. Because of its working principle is very similar to mining minerals, so named. In addition, bitcoin explorers who do mining work are also known as miners

bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system

bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network can get a qualified answer about every 10 minutes

then the bitcoin network will generate a certain amount of bitcoin as a reward to reward the person who gets the answer

extended data:

to be a miner, just "mine" bitcoin and search for 64 bit numbers by computer. By repeatedly decrypting with a computer, it competes with other gold miners to provide the number needed for the bitcoin network

if the computer can successfully create a set of numbers, it will get 25 bitcoins. Bitcoin is decentralized. It needs to create a fixed number of bitcoins per unit of computing time. It can get 25 bitcoins every 10 minutes

by 2140, the upper limit of bitcoin in circulation will reach 21 million. In other words, bitcoin system can be self-sufficient, which can be translated into coding to resist inflation and prevent others from sabotaging< br />

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

3. GPU is the meaning of graph line processor, the original design intention is to do graphics computing. GPU chip is essentially a collection of many small CPUs for image processing. Of course, each CPU can also do general operations such as addition, subtraction, multiplication, division or non shift jump, so it can also be used for mining. When GPU is mining, it wastes less chip area and power consumption than CPU, so mining efficiency is higher than CPU
What about ASIC? It is a more optimized circuit than the CPU mentioned above. There is no specific definition, but there is a rule in the field of chip design: the more general computing platform, the less efficient it is to complete specific computing. ASIC is the most dedicated computing platform. If we understand this, we can come to such a basic conclusion: in the mining field, if we use the computing power proof mechanism, as long as the CPU can dig, ASIC can dig. No matter what algorithm is used, ASIC can dig. There is no reason that CPU can dig, but ASIC can't, So the biggest difference between GPU and ASIC is their specific computing power.

4. 1. digital currency is abbreviated as digiccy, which is the abbreviation of "digital currency" in English. It is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy

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

ASIC mining is often used in bitcoin mining, which belongs to computational power proof. Hard disk mining is a kind of storage mining

bitcoin mining is only for sha256 hash value calculation, with single function. Although CPU can calculate, it is not cost-effective in terms of cost and efficiency. Therefore, mining machinery enterprises have specially designed ASIC chips for sha256 (or other algorithms) calculation

IPFs hard disk mining, interstellar Aoyun mining machine belongs to this, two mining methods:

1, storage mining, what you need to contribute is hard disk storage space, the more hard disk space, the higher your mining capacity. That is, the size of hard disk capacity and the number of hard disks

2. What you need to contribute to search mining is to provide network bandwidth. The larger the network bandwidth, the higher your mining capacity

hard disk mining does not need the strong computing power of ASIC, and ASIC does not need much hard disk capacity

The main differences between 7Nm and 10nm are as follows:

1, gate length is different. The width of the gate formed on the CPU is also called the gate length. The 7Nm process can integrate more transistors into CPU and GPU, and make the processor have more functions and higher performance

2. Different power consumption. For 7Nm technology and 10nm technology, the volume of 7Nm will be smaller when the same number of transistors are plugged. The large volume of 10nm, because of the process problems, will lead to the larger capacitance of the original, the required voltage is higher than 7Nm, resulting in higher overall power consumption

performance:

the chip is composed of transistors. The smaller the process, the more transistors in the same area of the chip, and the stronger the natural performance. The performance of 7Nm is better than that of 10nm

take Huawei Qilin 980 as Qilin 970, where Qilin 980 is a chip with 7Nm process and Qilin 970 is a chip with 10nm process

first look at the number of transistors, Kirin 980 has 6.9 billion transistors, Kirin 970 has 5.5 billion transistors, an increase of about 25.5%. In terms of performance, it's not as simple as 25.5%, because it involves not only the number of transistors, but also the upgrade of CPU, GPU, NPU and other IP cores

in terms of specific values, for example, the running points of CPU, Qilin 980, GPU and NPU are about 50% higher, twice as high

extended data:

integrated circuits have two main advantages for discrete transistors: cost and performance. The low cost is e to the fact that the chip prints all the components as a unit through photolithography, rather than making only one transistor at a time. The high performance is e to the fast switching of components, which consumes less energy, because the components are small and close to each other. In 2006, the chip area ranged from a few square millimeters to 350 mm, with a million transistors per mm
