Giveaway — Rafflecopter Proof of Fairness

On May 9, 2026 at 2:40 AM, Rafflecopter ran the giveaway “Giveaway” on Instagram. The winner was @tobyzess, selected from 100 unique participants using a cryptographically secure random number generator (CSPRNG) with SHA-256 hashing.

SHA-256 hash: c1e14f42b0b006fd146d26361a4a148e8e9bd2a53c5058612dfcf30c89868f9f

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.
