Giveaway — Rafflecopter Proof of Fairness

On May 9, 2026 at 2:44 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: 3f20305db5c9a160537796e812fcb1003294c34c4b2148b34a1faacd2140c2bd

Random seed: 3c003666fa141bee52735a2285da144773c3b9264415065a88c6821c730bf15e

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.
