Every prize competition on the ABOS network is cryptographically sealed before it opens and re-derived from public randomness after it closes. The moment an operator tries to manipulate a draw, this board turns red — for the whole world to see.
Each competition is sealed on four points — its setup, its instant-win allocation, its entry list and its draw. All four green means nothing was touched after lock-in. Edit a comp, reshuffle the instant wins, or announce the wrong winner and the tick goes red — public, permanent and automatic.
Note: the register cryptographically proves draw integrity — that the winner is fair and unriggable. Prize fulfilment (that the operator actually pays out) is tracked separately via verified-winner confirmations and a public dispute log per site.
This isn't a promise or a certificate. It's maths anyone can recompute — and because ABOS hosts every member site, reporting to this register is automatic and mandatory, not voluntary.
Before a single ticket sells, the site publishes a sealed hash of its secret. Timestamped here, it can never be backdated.
The winner is bound to a future drand round — the League of Entropy beacon nobody can predict or control.
At close, the winner is computed from the secret + the drand number over the exact list of sold tickets. No human chooses it.
The register fetches drand itself and re-derives every draw. Punters can recompute it in their own browser.
Any single mismatch flips the site to Failed verification and writes it to the permanent log. There is no path to a quiet fix.
