Wow, #China is really going against #Bitcoin: “financial institutions summoned for a meeting where they were urged to block payment services for any client accounts thought to be involved in cryptocurrency transactions. They were also told to cease offering other services such as account opening, registration and trading for any cryptocurrency-related activities. “Cryptocurrency transactions and speculative activities have disrupted the normal economic and financial order,” the [People’s Bank of China] said in a statement. “They increase the risks of crimes such as illegal cross-border transfers of assets and money laundering, which severely infringe upon the property safety of the general public.””

90% of China's #Bitcoin mining capacity shut down in June, which might explain why hashpower fell by about half; looking at bitinfocharts, it fell from 200 exahashes/second on its May 13 peak to 160 EH/s on June 9 to 70 EH/s on June 28, now back up to 110 EH/s

astoundingly incompetent #Bitcoin reporting from Slate: “To break through these codes, the computer has to figure out a particular block’s matching “key,” an algorithm-generated alphanumeric code also known as a “hash.” To match this hash, the computer has to generate its own guessed hashes and try them on the block until it finds the correct one”; “Bitcoin’s hashrate on Wednesday was equal to 104.041 terahashes per second, which translates to about 104 trillion individual hashes per second”; “Bitcoin operations alone end up draining trillions of energy watts a year”; “if you’re a climate-conscious consumer who subscribes to Twitter CEO Jack Dorsey’s fallacious case that Bitcoin can incentivize the further buildout of renewable energy”
apparently the #Xinjiang blackout in April took out a third of #Bitcoin’s hashrate. Also, wow, Digiconomist is pretty partisan; I hadn’t realized
45000 #Bitcoin mining machines seized in #Iran because they were using subsidized electrical #energy
The Dorsey/Square white paper arguing #Bitcoin subsidizes renewable #energy
a pretty lame rebuttal to the #Bitcoin renewables story
#Bitcoin shutdown in #China amounts to 90% of Chinese Bitcoin mining
