Cryptographic Trust — How to Verify Any Draw
Every draw publishes a SHA-256 hash BEFORE the winner is picked, and the seed AFTER. Anyone can re-run the algorithm and prove the winner is real.
How verification works
- Step 1 — Before the draw. We generate a random seed and publish its SHA-256 hash. The hash is committed publicly. The seed is hidden.
- Step 2 — The draw. Using the seed, we deterministically pick a winner with the Fisher-Yates shuffle. Same seed → same winner, always.
- Step 3 — After the draw. We publish the seed. Anyone re-computes SHA-256(seed) and verifies it matches the hash committed in Step 1.
- Step 4 — Re-run. Anyone reruns the algorithm with the published seed against the participant list and confirms the winner. Math, not trust.

Why this matters
Most giveaway tools say "random!" and ask you to trust them. We give you mathematical proof. If our algorithm ever picked a winner that doesn't match the published seed, anyone could publish the inconsistency in minutes. It's not just transparent — it's adversarially verifiable.
Verification algorithm: winnerIndex = (parseInt(sha256(seed + ":" + index), 16) mod participantCount) — Fisher-Yates shuffle with SHA-256-seeded RNG. Open-source verification page at /verificar.
