From a global perspective, the upstream and downstream of the bitcoin industry are mainly divided into four areas-mining, storage, trading and application. Mining is a visual description of the bitcoin production process. After a large number of calculations, the system will reward a certain amount of bitcoin after completing the workload proof required by the system. In the process of obtaining bitcoin through mining, how many times a node can perform calculations per second is computing power, and the proportion of computing power determines the proportion of bitcoin that can be dug. At present, professional mining mainly relies on professional mining machines whose computing power far exceeds that of personal computers, which leads to bitcoin mines and professional mining companies. Mine pool mode is the mainstream of mining, and mine pool refers to an open team mining server. At present, China has a strong competitive advantage in mining industry in the world. According to the statistics of Global Bitcoin Research Report 2014-20 16 in June, 2016, the top four mineral pools in the world are all from China, namely Fish Pool F2, AntPool Antpool, National Pool BTCC Pool and BW.com. The computing power of these four mineral pools accounts for 26.36%, 20.63%, 12.87% and 1 1.37% respectively.
