Title: "..mine bitcoins at the slowest possible speed."

Manchmal is weniger mehr.  :)

10.3 seconds per hash,
das muss ihm erstmal einer nachmachen.

Bitcoin mining on an Apollo Guidance Computer (http://www.righto.com/2019/07/bitcoin-mining-on-apollo-guidance.html)

Trying to mine Bitcoin on this 1960s computer seemed both pointless and anachronistic, so I had to give it a shot.

aber er wird ja schneller also nix mit Slowest Speed.

Sein Mining mit Pen and Paper war ja langsamer.

wahrscheinlich hat er angst vor schnellen rechnern und muss sich da erst rantastern...

im ernst: Hut ab vor der leistung

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 (https://de.wikipedia.org/wiki/Zuse_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.

Wäre doch nice gewesen direkt ein Block im Solomining gewonnen zu haben.
Da hätt die Welt gestaunt.

Aber eher eine Machbarkeitsstudie :-)

Also für so relativ komplexe Hashing-Prozeduren und den Umgang mit relativ großen Werten finde ich die 10 Sekunden schon überraschend fix. So leistungsfähig war/ist der Kasten ja wirklich nicht.
Meine KC85 aus den späten 80ern, der immerhin im Megaherz-Bereich taktet, hätte da sicher zu tun, hinterherzukommen.
