I have been in bitcoin since 2020 (long enough i feel) and have been fascinated by who Satoshi is ever since. I can recognise Hal by his quadriceps alone and today i am shocked to find out he has his own page on the web with old musings! I'm in for an exciting evening learning more about him, thanks for sharing.

An interesting thought on how to produce digital ecash notes that are inscribed programmatically.

My thought was to start the CA at the top and the bottom of the screen with the two different functions applied to the cash which should be equal if the cash validates (taking the number to the proper exponent on one hand, and applying the MD5 hash of the serial number on the other, for the case of magic money). Then we work inwards with the two seeds. Proper cash will produce a symmetrical pattern.
Why would it produce a symmetrical pattern?
