Mining machine mining is the only way to produce bitcoin. In one moment, all the mining machines through the Internet have the same mathematical problem. Whoever gets the correct answer first has the right to keep accounts once. At the same time, he gets the mining reward of bitcoin's main network. At present, each reward is 12.5 BTCs.

Bitcoin is an encrypted digital currency produced by open-source P2P software. It does not rely on the issuance of specific monetary institutions, but is generated by a large number of calculations of specific algorithms. In the whole P2P network, many nodes (each miner and each miner can be regarded as a node) constitute a decentralized database to confirm and record all transactions. Each transaction must be confirmed by more than half of the nodes in the whole network before it can take effect. This is why P2P The decentralized feature and algorithm of the can ensure the security of digital assets on the main network

In theory, any computer can become a mining machine, but because of its weak computing power, the revenue will be relatively low, and it may not be able to earn an opportunity to keep accounts for ten consecutive years. So many companies have developed professional mining machines, which carry customized chips running specific algorithms. The mining efficiency of such professional mining machines is dozens or hundreds of times higher than that of ordinary computers.

As of 2020, the main brands of mining machines in circulation on the market include:

Ants, Shenma, Avalon, Xindong, yibit, etc. The mainstream models are ant S17, Shenma M20S, Avalon 1066, etc., with a computing power of 50-73t and a power consumption of 2800w-3600w.

In general, the higher the computing power of the miner, the more bitcoin will be dug in unit time.

Here is the basic structure of a miner:

Taking the ant miner S9 as an example, the main structure is: control board + calculation board + power supply

The above is the hardware composition of a typical ASIC miner. The control board is equivalent to the main board of our computer, and the computer power board is the CPU of the computer. The computer power of the miner is provided by the customized chips on the computer power board, and the final power supply is responsible for stable power supply. Although the miner model has been constantly upgrading and iterating, mainly the continuous updating of the chip carried by the miner, the other components will not be too different. Knowing a miner can basically understand the internal structure of other miners.
