Giveaway — Rafflecopter Proof of Fairness

On August 23, 2026 at 1:16 PM, Rafflecopter ran the giveaway “Giveaway” on Instagram. The winner was @zineb_ouchfik, selected from 10 unique participants using a cryptographically secure random number generator (CSPRNG) with SHA-256 hashing.

SHA-256 hash: 420d0992e188ab8296b61a895331e52576edd32b880a97980915732f6b9acd36

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.
