Odaily, citing Bitcoin.com News, reported that the Apollo Guidance Computer was programmed in 2019 to run Bitcoin mining code, with each double SHA-256 hash taking 10.3 seconds. The machine, originally used for navigation and engine control during the Apollo missions, had roughly 4KB of memory. A team led by computer scientist Ken Shirriff verified the program against already-mined block 286,819, though the test did not produce any Bitcoin. At the time, when Bitcoin network hash rate was about 65 EH/s, the device was estimated to need around a million times the age of the universe on average to find a block. After the Sept. 5 difficulty adjustment, Bitcoin network hash rate stood at 934 EH/s and mining difficulty rose to 127.45 trillion, about 14 times higher than in 2019. Based on those figures, the Apollo Guidance Computer would now need roughly 13 million times the age of the universe on average to mine a single block.
