ASIC miner
ASIC miner refers to the miner which uses ASIC chip as the core operation part. ASIC chip is a kind of chip specially designed for a specific purpose. It must be noted that it is not only used for mining, but also has a wider range of applications. This kind of chip is simple and efficient. For example, bitcoin adopts the sha256 algorithm, so bitcoin ASIC miner chip is designed to only calculate the sha256. Therefore, in terms of mining, the performance of ASIC miner chip exceeds the current top computer CPU. Because ASIC mining machine has absolute advantage in computing power, so computer, graphics card mining machine began to be phased out
 
What's mining? What's bitcoin?
1. Bitcoin mining machine is a kind of computer used to earn bitcoin. This kind of computer generally has professional mining chips and works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server. Mining is actually a competition of performance and equipment, and a competition of computing power among miners. Miners with more computing power are more likely to dig bitcoin. With the increase of computing power in the whole network, it is more and more difficult to dig bits with traditional devices (CPU, GPU). People have developed chips specially used for mining. Chip is the core part of mining machine. The process of chip operation will produce a lot of heat, in order to cool down, bitcoin miner is generally equipped with heat sink and fan.
 
2. Bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. The miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by the miners, so the competition for mining is very fierce. Bitcoin mining began with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high.
