I trained the fly brain to roll dice.
Dice are the OG way to make a Bitcoin key, no computer you have to trust, just physics. So I gave the job to a fly, 100 rolls so you don't have to.
FlyBrain Dice runs the MaleCNS connectome sim, feeds it a looming cue, and lets its descending neurons fire a catapult in MuJoCo. Different torque, twist axis, and start position to every throw to ensure randomness.
The rolls are then hashed into a Bitcoin private key.
If you want the real thing: the ZERO does the rolling for you.
During onboarding it builds your key from its own entropy plus your fingerprint and ambient light — then lets you re-roll parts of it yourself. You become a source of entropy in your own key.
