Local sources report that government from the city of Baoshan in the Chinese province of Yunnan are escalating efforts to fissure down on Bitcoin miners, ordering electricity producers to stop supplying power to the urban center'south miners.

On Nov. 30, Chinese crypto reporter Colin Wu tweeted that several miners had informed him of the ban, sharing what announced to be scanned copies of official documents issued to power producers:

However, Wu added that the ban was probably informed by localized "economical interests," and probably is not indicative of a want to quash crypto mining on the part of Beijing:

"In that location is no demand to overestimate the impact of this incident. The attitude of People's republic of china local ability companies towards crypto mining is often irresolute. It is more a demand for economic interests than political pressure level."

The ban appears to have coincided with a 24-hr drop in global hash rate of roughly 10% from 140 exahashes per second to 125 EX/s, though correlation is far from causation.

Co-ordinate to Cambridge Academy's Bitcoin Electricity Consumption Alphabetize, Yunnan was Red china's fourth-largest region past mining hash charge per unit, behind Xinjian, Sichuan and Inner Mongolia every bit of April 2020. Yunnan and then represented 5.42% of global hash rate — ranking it above all countries except for China, the U.s., Russian federation and Kazakhstan.

In June, Wu reported that Yunnan's government had ordered 64 unauthorized mining operations to shut down, including seven that were all the same under construction. The regime cited tax evasion and security risks including how the mines were wired to local hydropower stations.

During that same month, a local Bitcoin mine caught on fire, resulting in the incineration of thousands of units.

The mid-year crackdown also followed a May 29 explosion at a hydropower station in Yunnan that killed six people and injured 5. The explosion was believed to take prompted greater enforcement of safety standards concerning hydropower plants in the region.

In April, Yunnan'south country grid also issued a document warning electricity producers against the unauthorized diversion of power to Bitcoin mines.
