Cryptocurrency mining rig maker Ebang was accused of inflating sales figures in a short report, while competitor Canaan reported declining fourth-quarter revenue. The end may be nigh for distributed ledger protocol Filecoin, while overseas interest in Chinese cryptocurrency exchanges is on the rise. Finally, Chinese researches say that crypto mining energy consumption could undermine sustainability initiatives.


The world of blockchain moves fast, and nowhere does it move faster than China. Here’s what you need to know about China’s block-world in the week of April 6-13.

The crypto mining rig makers

  • Cryptocurrency rig maker Ebang’s stock lost 20% of its value in four days after a short report from Hindenburg research accused it of fraud. The stock has dropped another 5% since April 12. (TechNode)
  • Canaan (finally) reported its fourth quarter and full-year 2020 earnings. The company’s revenues continued to decline though it narrowed its losses. The company’s outlook was more positive: It said that it has laid a “solid foundation” for growth in Q1 2021. (TechNode)
  • Bitmain sued relative newcomer MicroBT for intellectual property theft for the second time. MicroBT’s founder was a chip engineer at Bitmain. A previous lawsuit over similar claims was dismissed by a Beijing IP court in 2018. (The Block)

The bell tolls for Filecoin

The Distributed Storage Office of China’s Communications Industry Association warned that Chinese companies are using distributed file storage protocol Filecoin to issue unauthorized wealth management products and conduct illegal financing.

Mining and threats

In March, the province of Inner Mongolia proposed shutting down crypto mines to meet green development goals. (Nature Communications)
