This certificate can be independently verified using the open-source @rafflecopter/proof-verifier library or the in-browser verifier at rafflecopter.app/verify. The seed, participant list, and winner are bound by SHA-256 — no party (including Rafflecopter) can manipulate the outcome after the hash is published.
