What is mining machine computing power? How to convert mining computing power units

What is mining machine computing power?

One of the words we often mention in digital currency mining is the computing power of the mining machine, for example: Antminer S9 has a computing power of 13.5T, Antminer L3+ has a computing power of 504M

So what does computing power mean? What does computing power represent and how is the computing power unit defined?

In fact, the meaning of computing power is very simple. It represents the computing power and performance of the mining machine. It specifically represents the number of overall hash algorithm operations of the mining machine per second.

We must first know that the essence of mining is to solve a mathematical calculation. Whoever solves it first will get the reward (coin). The mathematical calculation method is also very simple, which is to keep trying to collide the results.

It's like you brute-force a phone password (assuming the phone doesn't get locked after multiple attempts)

You keep trying the password from 111111 to 99999 one by one until you succeed.

If you can try once in 1 second, your computing power is 1 time/s. If you can try twice in 1 second, your computing power is 2 times/s.

The more times you try in 1 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 a mining machine can calculate in one second, the greater its computing power and the more coins it can mine.

Bitcoin was first mined using CPUs, then GPUs, and now ASICs, which are customized chips, have been used to mine Bitcoin. The computing speed has been continuously improved.

Hash power unit:

The computing power is divided into units every thousand, and the smallest unit is H = 1 time. 1000H = 1K 1000K = 1G 1000G = 1T 1000T = 1P 1000P = 1E

S9 13.5T is also equal to 13500G / 0.0135P

The total computing power of Bitcoin network is now 24.42 EH/s, which is equivalent to the computing power of 1.8 million S9s.

Hashrate of different currencies

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 randomly entering the 4-digit password for phone 1, and the 6-digit password for phone 2. You have to wait 1 second before entering it again. In reality, it is much more complicated than this.

The methods of unlocking these two different phones are different, so the speeds I try to unlock are also different. I will be faster when unlocking phone 1.

There is no relationship between the computing power of different currencies. A Bitcoin mining machine cannot mine Litecoin because the algorithms are different. It cannot solve Litecoin problems.
