Computing power is a measure of bitcoin network processing power. That is, the speed at which the computer calculates the output of the hash function. Bitcoin networks must perform intensive mathematical and encryption related operations for security purposes. For example, when the network reaches a hash rate of 10th / s, it can perform 10 trillion calculations per second
in the process of getting bitcoin through "mining", we need to find its corresponding solution M. for any 64 bit hash value, there is no fixed algorithm to find its solution M. we can only rely on computer random hash collisions. How many hash collisions can a mining machine do per second is the representative of its "computing power", and the unit is written as hash / s, This is called workload proof mechanism pow
computing power provides a solid foundation for the development of big data, and the explosive growth of big data poses a huge challenge to the existing computing power. With the rapid accumulation of big data in the Internet era and the geometric growth of global data, the existing computing power can no longer meet the demand. According to IDC, 90% of the global information data is generated in recent years. And by 2020, about 40% of the information will be stored by cloud computing service providers, of which 1 / 3 of the data has value
therefore, the development of computing power is imminent, otherwise it will greatly restrict the development and application of artificial intelligence. There is a big gap between China and the advanced level of the world in terms of computing power and algorithm. The core of computing power is the chip. Therefore, it is necessary to increase R & D investment in the field of computing power to narrow or even catch up with the gap with the developed countries in the world
unit of force
1 KH / S = 1000 hashes per second
1 MH / S = 1000000 hashes per second
1 GH / S = 1000000000 hashes per second
1 th / S = 100000000000 hashes per second
1 pH / S = 100000000000 hashes per second
1 eh / S = 100000000000 hashes per second
computing power refers to computing power, refers to that in the process of getting bitcoin through "mining", we need to find its corresponding solution M. for any 64 bit hash value, there is no fixed algorithm to find its solution M. we can only rely on computer random hash collisions. How many hash collisions can a mining machine do per second, is the representative of its "computing power". The unit is written as hash / s, which is the so-called proof of work mechanism (POW)
the general computing power of the graphics card is a few gigabytes, while the professional miner chip is as high as several thousand gigabytes. Take bm1387, the chip with the lowest power consumption in the world, as an example, the S9's computing power is as high as 14T, the power consumption on the wall is only 1400W, and the rated computing power reaches 13.5 Th / s ± 1 J / GH + 12% (wall, AC / DC 93% efficiency, 25 ° Rated voltage: 11.6 ~ 13.0v, in addition, in the case of non independent power supply, three power calculation boards can be connected to different power supply respectively, but each power calculation board can not be connected to multiple power supply, and ensure that the power calculation board is finally powered on
among the mining machines, ant mining machine is my favorite. At the same time, based on the average investment cost of bitcoin in the early stage, ant S9 can basically recover the capital in about five months, and the income in the later stage is immeasurable.
mining is definitely the first professional mining machine, many new children's shoes will choose to use graphics card mining, but the graphics card mining is just like using "magic oil" to do a professional thing, but the efficiency is certainly not high. To dig bitcoin, we should pay attention to the following points: first, computing power (i.e. mining speed), second, power consumption, and third, stable performance. Computing power, bitcoin mining is faster than problem-solving speed, so it is self-evident that speed is more important; Power consumption is directly related to efficiency, that is, the issue of cost expenditure; The stability of performance mainly depends on the stability of calculation force when the working frequency is constant. Just think about it, no one wants the miner to lose its computing power every so often, or even break down. After all, it's all money ~

My world mining. Now let's take you to learn about the latest and complete strategies and news about my world mining. Let's have a look ~
together How does my world mine? In my world, ore is a very important resource, and the main way to obtain mineral resources is to mine by oneself. Next, I'll tell you about my mining methods in the world. Let's have a look
{ RRRRR}
1. Choose one of the many open-air caves and start exploring, making your exploration path as downward as possible. Even shallow caves can provide abundant reserves of coal and iron ore, and there are other deposits such as gold ore in deeper layers
2. If you don't find an easy access cave entrance, but find a shaft or Canyon, mining there is also a good choice
3. Of course, you can also make your own entrance to the underground world: dig a vertical shaft in a convenient location (such as the basement of a room), and then start digging horizontally at a suitable height
