Giveaway — Rafflecopter Proof of Fairness

On May 20, 2026 at 1:16 PM, Rafflecopter ran the giveaway “Giveaway” on Instagram. The winner was @_.ngaho, selected from 170 unique participants using a cryptographically secure random number generator (CSPRNG) with SHA-256 hashing.

SHA-256 hash: 276a4542f59a142748850ab0c77b258305c24a10539bc4219ebae23817feb01d

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.
