Before the rise of the blockchain, miners specifically referred to workers who dig coal mines. The group impression was that people were covered with coal dust, and their skin was dark outside their clothes.

After the birth of the blockchain, miners are no longer just short for coal miners, but have a new meaning: people engaged in virtual currency mining.

Unlike the traditional "miners", miners in the blockchain industry have more scientific and technological colors. The main job of a miner is transaction confirmation and data packaging. If you want to become a miner, it is actually relatively simple. Buy a dedicated computing device and download the mining software to start mining. Mining does not require the miners to do it themselves. In fact, the computer performs specific operations. Miners only need to ensure the power supply and the network connection of the computer.
