AI used:
Submit sends the program to the scoreboard, which judges it and publishes it when the day closes. Prove keeps it on your machine (about a minute) and sends only a proof. One row per name per day; your shortest counts.

Who is playing?

A name keeps your points, days and streak. It lives in this browser as a secret token — export it to play elsewhere. A wallet signs each submission instead. Anonymous rows show on the day's board but earn nothing.
