Provably-Fair Lottery Verifier
Don't trust — verify. Recompute any ZanoX lottery draw yourself, right in your browser, from the on-chain block hashes. The example below is a real resolved draw.
Winning number 358 appears in block hash #5 (position 14) of the 7 on-chain hashes in this seed. The result was derived from block hashes, not chosen — provably fair.
How it works
When a ZanoX lottery draw closes, its winning number is derived from a set of Zano blockchain block hashes that only exist after the draw ends — so no one can know or pick the result ahead of time. Those hashes are published with the result as the draw seed.
To verify, this tool takes each of the seven block hashes, removes the letters to leave only digits, and scans every three-digit window (001–999). If the winning number appears among them, the result is confirmed as computed from the blockchain — the definition of provably fair. The check runs entirely in your browser; nothing is sent to ZanoX.
Frequently asked questions
How does ZanoX make its lottery provably fair?
Each draw's winning number is derived from on-chain Zano block hashes that exist only after the draw closes — so the operator cannot know or choose the result in advance. The draw seed published with every result is the list of those block hashes.
How do I verify a draw?
Paste the draw seed (the dash-separated block hashes shown with a draw result) and the winning number into the tool above. It strips the letters from each hash, scans every 3-digit window, and confirms the winning number appears among them.
What does "verified" mean here?
It means the winning number genuinely appears inside the on-chain block hashes for that draw — confirming the result was computed from the blockchain, not picked by anyone.
