Check it yourself

Every ticket's issue, change of hands, cancellation and check-in goes into an append-only log. Its fingerprint (a Merkle root) is published on-chain at least hourly, so nobody, Aventix included, can rewrite a ticket's history unnoticed. Your ticket's page shows its history with proofs; to check a ticket you're buying, use Check a ticket.

Draws

Waiting-room places and resale offers are drawn from a seed we commit to (and anchor) before the draw and reveal after it. Anyone can recompute the order: rank = sha256(seed + ":" + entry ID), lowest first.
