I implemented the SHA-256 hash algorithm and ran it on the Apollo Guidance Computer that we're restoring, taking 10.3 seconds per hash. This isn't my first experiment with absurd Bitcoin mining. I tried mining by hand with pencil and paper; this had a hash rate of 0.67 hashes per day. Using an IBM punch card mainframe computer from the early 1960s got the hash rate up to 80 seconds per hash. My fastest implementation was on a Xerox Alto (the famous 1973 computer that inspired the Macintosh), which performed 1.5 hashes per second.
What's next?
Ich schlage Mining auf einer
Z3 vor.
Z3 ist eine schöne Sache, ich werfe mal den TI 84 in den Raum, der sollte ja eigentlich gut rechnen können.
Generell aber ein cooles Projekt, ich mach so anachronistische und eigentlich sinnlose Experimente.
