Provably Fair Draw Verifier

Every Buzzeee giveaway and live chat roll uses a commit-reveal protocol. You don't have to take our word that a draw was fair — your browser recalculates the exact math right here on your device.

STEP 01

1. Seed Locked First

Before anyone joins, a secret random seed is generated and its SHA-256 fingerprint is published publicly so it can never be changed later.

STEP 02

2. Entrants Frozen

When entries close, the full list of participants and their ticket weights is sorted and locked into a single tamper-proof manifest hash.

STEP 03

3. Anyone Can Replay

Once drawn, the secret seed is revealed. Combining the revealed seed and frozen entrant list always produces the exact same winner.
