A word we often mention in digital currency mining is the computing power of the mining machine, such as Antminer S9 computing power 13.5T, Antminer L3+815G, what does computing power mean? What does computing power mean? ? How is the computing power unit defined? In fact, the meaning of computing power is very simple. It represents the computing power and calculation performance of the mining machine. He specifically represents the number of operations per second of the overall hash algorithm of the mining machine. We first need to know that the essence of mining is to solve a mathematical calculation. Whoever calculates it first will get a reward (coin). This mathematical calculation method is also very simple, that is, constantly trying to collide the results.

For example, if you want to crack a mobile phone password, you keep trying the password from 111111 to 99999 one by one until you unlock it successfully. If you can try once within 1 second, your computing power is 1 time/s; If you can try twice in one second, your computing power is 2 times/s. The more you try in one second, the greater your computing power will be, and the shorter your unlocking time will be. The same is true for mining machines. The more hash algorithms that the mining machine can calculate within 1 second, the greater the computing power and the more coins it can mine.

In the beginning, Bitcoin was mined with CPU, later with graphics card GPU, and now with ASIC professional customized chip mining, the calculation speed has been continuously increasing. Hash rate unit: Hash rate is divided into a unit every thousand digits, the smallest unit H=1 time, 1000H = 1K, 1000K = 1G, 1000G = 1T, 1000T = 1P, 1000P=1E. Antminer S9 13.5T is also equal to 13500G / 0.0135P. Bitcoin's entire network computing power is now 24.42 EH/s, which is equivalent to the computing power of 1.8 million Antminer S9s.

The mining algorithms of different currencies may be different. For example, Bitcoin uses the sha256 algorithm, Litecoin uses the scrypt algorithm, and Ethereum uses the Ethash algorithm. This is like the password of mobile phone 1 is 4 digits, and the password of mobile phone 2 is 6 digits. , Input again after 1s after input.

There is no relationship between the computing power of unused currencies. Bitcoin mining machines cannot mine Wright, because the algorithm is different, and it will not solve the problem of Litecoin.

Since the competition for mining machines is so fierce, then, if you want to mine, how to choose a mining machine? In theory, of course, it is best to choose the latest model. The latest mining machines will consume less power and have very high computing power.

1. Look at computing power: It is to look at the ability of a computer to perform operations, that is, how many hash operations the machine can perform per second. At present, the computing power of mainstream Bitcoin mining machines is 14T, which means that hash collisions are carried out to the power of 14*10^13 per second.

2. Look at the power consumption: it is an indicator of the power consumed by this mining machine during operation. Power consumption will have a huge relationship with the cost of mining. A mining machine generally runs 24 hours a day to mine, so the power consumption sometimes seems to be a little bit different, but in fact, the cost difference in a year is still relatively large.

3. Look at the historical reputation: There are now two most well-known Bitcoin mining machine manufacturers in the world, Bitmain's Ant mining machine and Canaan's Avalon mining machine. The latter is also the invention of the world's first ASIC chip mining machine. By. ASIC refers to an integrated circuit designed and manufactured in response to specific user requirements and the needs of specific electronic systems. Nowadays, mining machine companies basically started with chips. The mining machine is composed of chips, cooling fans, batteries and other components. Among them, the core component that determines whether the mining machine can dig more coins is the chip. Digital assets of the same algorithm can be mined with the same mining machine. For example, Bitcoin (BTC) mining machines can also mine Bitcoin Cash (BCC); Ethereum (ETH) mining machines can also mine Ethereum Classic (ETC).

Of course, you also need to consider the stability of the mining machine and after-sales service.Or, you can go to ZEUS MINING, where you can learn more about them.
