ASIC mining
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 />
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.
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

when the vast majority of video card mining machines and CPU mining machines are in a mine disaster, bitcoin mining with ASIC mining machines will not be affected. As the first big man in the virtual currency circle, bitcoin has become a deep-rooted belief in the coin circle. The total number of 21 million bitcoins also determines the transaction type and value-added of bitcoin
although bitcoin has begun to be recognized by most people, it has not really replaced the world's currency to fulfill its original intention, but it has become a collection beyond gold. The inflation of money, the rection of the total amount of mining and the increasing difficulty of mining all determine its future market prospects. The value-added has been firmly established, so people will rush to dig for mines, Because the bitcoin is actually worth more than gold
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
