Provable Chance by Botlok
A proof link for draws people might challenge.
Before the draw, post a pool-lock link. When the winner is announced, post the proof link. Entrants can check their own entry was included and verify the winner came from the locked pool.

What members can check:
- Was my entry included?
- Was the list locked before the winner was selected?
- Did the announced winner come from that locked list?
Certified RNGs prove the number was random.
We prove the pool — the list was locked before the draw and unchanged after.
Any entrant can check the draw against the locked list and public randomness source. For full independence, the result can be reproduced from the published inputs and steps.
Plain English: drand is the public randomness source. The pool digest is the fingerprint of the locked entry list.
Provable Chance proves selection-event integrity only. It does not certify promotion legality, rule fairness, entrant eligibility, prize fulfillment, or regulatory compliance.
