Giveaway — Rafflecopter Proof of Fairness

On September 3, 2026 at 3:35 PM, Rafflecopter ran the giveaway “Giveaway” on Instagram. The winner was @elenapaolina, selected from 1.000 unique participants using a cryptographically secure random number generator (CSPRNG) with SHA-256 hashing.

SHA-256 hash: 8a537af3abeba17b810560f2ba149c13adf1d1646f79672e9c7a332f098c3ebf

Random seed: 04ec8f863b2008a6f2255dfd5764e4138bfbadedd07ea5d4e5f492fd829006a2

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.
