How the draw works, piece by piece
Sealed seed, public drand randomness, anti-fraud filtering, prize reassignment: DrawSeal’s mechanisms explained one by one, and exactly what they guarantee.
What happens if a giveaway winner doesn't respond?
A giveaway winner who never claims the prize? DrawSeal reassigns it through a deterministic, traceable process built on the same public drand draw.
The list seal: proving nothing changed without publishing the entrants
Publishing the entrant list would breach the GDPR. Publishing its fingerprint proves it hasn't moved, without revealing a single person.
drand: why your draw's randomness doesn't come from us
The randomness doesn't come from our servers but from drand, a public source produced by an independent network. Why that's the only acceptable answer.
The sealed seed: why its fingerprint is published before the first entry
Publishing sha256(seed) before entries open makes changing the seed afterwards impossible. What that fingerprint forbids exactly, and what it doesn't cover.
Unclaimed prize: how a re-draw stays as verifiable as the first
Reassignment is where most setups improvise. How a re-draw stays verifiable, and why the order of designations matters.
