09 · QUANTUM-TIMED BUYBACK

A buyback nobody can see coming, not even us

20% of every creator fee goes to the buyback wallet, and it buys the token back once a day. When it happens is decided round by round: after the draw, every new drand round is hashed with the day's quantum value, and the buyback fires on the first round that falls under a fixed threshold.

Rule

CheckFor each drand round r after the day's seal: h = SHA-256(value ‖ randomness r).
FireIf the first 8 bytes of h, read as a number, are below 2⁶⁴ / 9,600, the buyback executes in that round. On average that is once every 8 hours.
FallbackIf no round fires by 17:00 UTC the next day, it runs at 17:00, so it happens every day.
ProofThe firing round and its hash are written next to the day's record. Anyone can recheck every round before it.
