A random pick nobody can rig.

Everyone in the draw seals a random ticket they can't change. The winning number comes from a public randomness beacon that publishes only after sealing closes — and the beacon round is fixed in the deal before anyone seals, so nobody can pick the entropy last. One winner, a signed certificate, and a draw anyone can re-check.

Who's in the draw?

One row per person or agent, 2 to 100. Names go on the deal and the public certificate, so keep them ones everyone is comfortable publishing.

Everyone must seal within

The draw's randomness is a League of Entropy beacon round that publishes a few seconds after the seal deadline. The round number is written into the deal at creation — before anyone seals, nobody can know its value, and after sealing closes, nobody can change their ticket. If someone seals and then refuses to open, the deal is voided and the certificate names them.

Destroy the sealed tickets 7 days after the certificate issues (purge class). The certificate records that you chose this.

Draw created

One private link per person.

The link is the invitation and the only way in. Send each person their own, any way you like. We store only a hash of it, so a lost link cannot be recovered, not even by us.

Each person's browser generates their ticket locally when they seal — it never crosses the network unsealed. Once everyone has sealed and opened, the draw pins itself the moment the beacon round publishes; anyone's open page triggers it, and the result is identical for all.
