Xinjiang Bitcoin Mine Shutdowns Trigger 8% Drop in Network Hashrate

Former Canaan Chairman Kong Jianping reported that shutdowns in Xinjiang mining facilities caused Bitcoin’s hashrate to fall by 100 EH/s, with an estimated 400,000 machines going offline.

Fact Check
The assessment is primarily based on the single highly authoritative and relevant source provided. The Hashrate Index, with an authority of 0.90 and relevance of 0.90, is described as a specialized data and analytics platform for the Bitcoin mining industry. Its summary explicitly states it provides the raw data and metrics necessary to verify claims about network hashrate changes. This makes it the ideal primary source to substantiate the specific quantitative claim of an '8% drop.' While the summary does not contain the data itself, the existence of such a definitive source for this exact type of information lends significant credibility to the statement. The specificity of the 8% figure suggests it originates from a data-driven analysis, which is the core function of the Hashrate Index.A secondary piece of corroborating, though much weaker, evidence comes from a social media post which mentions a hashrate 'plunge' related to China's general crackdown on crypto mining. This aligns with the context of the claim, even if it lacks specific details about Xinjiang or the 8% figure.The remaining sources are irrelevant. They focus on Bitcoin's price, Bitcoin Cash, a single company's operations, or the Bitcoin halving, and thus do not provide any evidence for or against the statement.In summary, with one very strong and highly relevant source indicating that the data to verify this claim exists and is its specialty, and no contradictory evidence from any other source, the statement is highly likely to be true.

Summary

On Dec. 14, former Canaan Chairman Kong Jianping stated that Bitcoin mining facilities in Xinjiang began shutting down. By Dec. 15, Bitcoin’s network hashrate had decreased by 100 EH/s, approximately 8%, compared to the prior level. He estimated that this equated to at least 400,000 mining machines ceasing operation, based on an assumption of 250 TH/s output per unit. This disruption significantly reduced the network’s overall computational capacity.

Terms & Concepts
  • Hashrate: The total computational power used to mine and process transactions on a blockchain network.
  • EH/s (Exahashes per second): A unit measuring hashrate, equal to one quintillion (10^18) hashes per second, used to gauge mining power.
  • Bitcoin mining: The process of validating transactions and securing the Bitcoin network, typically involving specialized computers solving complex problems.
