Giveaway — Rafflecopter Proof of Fairness

On May 10, 2026 at 12:53 AM, Rafflecopter ran the giveaway “Giveaway” on Instagram. The winner was @alexisvmacias, selected from 13 unique participants using a cryptographically secure random number generator (CSPRNG) with SHA-256 hashing.

SHA-256 hash: 8a30db42fdb16d4c36001d75fcf55efc07262d18ead1f419b135082b9c319422

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.
