Sharing the QR code < / P > < p > with wechat scanning code to friends and circle of friends < / P > < p > virtual currency "mining" brings high power consumption and implies financial risks. Therefore, relevant departments have introduced strict supervision measures Under the strict supervision of < p > < / P > < p > < p > all localities have also continuously tightened the power cleaning and rectification of "mining" enterprises, and expanded from switching off power in the past to sealing up mining machines and troubleshooting IP. After a multi pronged approach, China's bitcoin mining computing power fell precipitously, and the "mining" of virtual currency was completely banned in China. At present, the clean-up work has achieved remarkable results, but some new problems encountered in some areas also need to be paid attention to < p > under strict control, the domestic computing power has returned to zero < / P > < p > Xiaosan's "mining" has not disappeared < / P > < p > Hong Jian (pseudonym) is a post editor of a video production company in Shanghai. His colleagues and friends never imagined that such a young man who clocks in on time every day "has a mine at home" 。 < p > over the past three years, Hong Jian commanded his father in his hometown in Jiangsu, which is separated by a river, to start the system. He used remote control software to operate the "mining machine" to mine virtual currency. Until mid October, the power consumption was 35000 kwh per month, far exceeding that of normal residents and individual industrial and commercial households, so he was listed as an abnormal power user and suspended power supply < p > in fact, Hong Jian initially remotely controlled the machines in his hometown just for "video rendering" at work, but seeing the crazy trend of virtual currency, he transformed the top floor of his hometown's three-story building into a "mine", successively added more than 50 equipment and joined the "mining army" < p > "bitcoin needs professional mining machines, and ordinary computer equipment can only dig ether. At the beginning of 2017, ether was only $10 each, and by the beginning of 2018, it had risen to $1000 each." Said Hong Jian < p > the reporter saw at the scene that there are two rooms on the third floor, one of which is full of shelves, on which the graphics card, motherboard and power supply are arranged by regional number. In order to dissipate heat, a large electric fan is installed on the wall. The other room is used as a warehouse, full of machinery and equipment. Open the operation host to enter the "mining" program, and the word "start mining" is clearly displayed on the display screen < p > because more and more machines are added, ordinary civil electricity can no longer meet the demand of "mining", so Hong Jian applied to the local power supply station for the installation of 250kV transformer under the name of "computer sales and service" of individual industrial and commercial households. Before being listed as abnormal electricity users, it can dig about 3 ether coins per month on average < p > "the monthly electricity charge is more than 20000 yuan. With the equipment investment, the revenue and expenditure are basically balanced, and no money is earned." Hong Jian said he was going to sell the equipment while the price of the graphics card was good < p > virtual currency "mining" refers to the process of producing virtual currency through special "mining machine", which consumes extremely high energy. In September this year, the national development and Reform Commission and other 11 departments jointly issued a document to regulate "mining", strictly prohibit the addition of virtual currency "mining" projects, and accelerate the orderly exit of stock projects < p > the reporter noted that due to large power consumption, the previous large-scale and industrialized "mining" projects were dominated by hydropower and thermal power, mainly concentrated in central and western regions such as Inner Mongolia, Xinjiang, Sichuan and Yunnan. In order to absorb surplus power and drive local tax and economic development, some places attract investment in the name of building a data center, so as to make the "mining" projects work quickly < p > on May 21 this year, the financial stability and Development Commission of the State Council held its 51st meeting, emphasizing the firm prevention and control of financial risks, "cracking down on bitcoin 'mining' and trading, and resolutely preventing the transmission of individual risks to the social field". This is regarded by the outside world as the first time that bitcoin "mining" and trading at the national level clearly put forward the strike requirements. As a result, some "mining" projects were quickly shut down until 11 departments jointly issued a document, and the large "mines" that often consume millions of degrees of power per day withdrew < p > in October this year, the data released by Cambridge alternative Finance Research Center showed that from May to July 2021, China's share of computing power required in global bitcoin "mining" activities fell from 44% to 0, and the United States, Russia and Cambodia became new mining centers. In 2019, China accounted for three-quarters of global computing power < p > "this statistical data shows that at present, the computing power of bitcoin 'mining' in China has been 'zero functionality' on the macro level." Professor Liu Xiaolei, director of the Department of finance of Guanghua School of management of Peking University, said, but it does not rule out that there are still "mining" through overseas agents, or scattered and statistically small mines < p > from the local situation, although large-scale "mining" such as institutions is completely prohibited in China, there are still some individual "mining" behaviors in various places < p > in October this year, Jiangsu Provincial Communications Administration issued a document on its official website, saying that the monitoring found that the total number of Internet IP addresses involved in "mining" in Jiangsu Province was 4502, which consumed more than 10ph / s of computing power resources and 260000 kwh / day. "Mining" activities mainly focus on virtual currencies such as Ethereum and bitcoin < p > following this clue, the reporter successively went to Xuzhou, Changzhou, Suzhou, Nantong and other cities for investigation and found no large-scale "mining" projects. The verified "mining" IP address is mostly personal "mining" behavior. For example, the verified "mining" IP address of Xuzhou belongs to two Internet cafes < p > this kind of "mining" behavior hiding in residential buildings and Internet cafes also exists in some other places. For example, in late October this year, residents of a community in Chaoyang District, Beijing used fire corridors to place computers for "mining" and were reported and verified. At the same time, monitoring in Jiangsu, Zhejiang and other places found that someone was suspected of using public resources to engage in "mining" < p > the general rectification has achieved good results < / P > < p > there is still a blind spot in the supervision of individual "mining" < / P > < p > as for the next rectification work, Meng Wei, spokesman of the national development and Reform Commission, said at a regular press conference in November this year: for units implementing residential electricity price, if they find that they participate in virtual currency "mining", they will study the imposition of punitive electricity price, Form a high-pressure situation of continuously renovating the "mining" activities of virtual currency < p > local regulatory requirements are also escalating. However, the reporter learned from the field visit that due to different resource endowments, all localities also face some problems in the process of policy implementation. At the same time, due to the large number of regulatory departments involved, there are some problems, such as poor communication and connection between departments, poor cooperation, fuzzy relationship between rights and responsibilities and so on. Especially for the control of non enterprise "mining" behavior at this stage, there is still a regulatory blind spot < p > "the decentralized 'mining' of natural persons is neither large-scale nor enterprise. The national development and Reform Commission and the Ministry of industry and information technology have no way to deal with such 'mining' behavior." Wuxi Digital Economy Research Institute ?
