How to verify BC.Game Keno
- Reveal the seed. Open BC.Game’s provably-fair panel and rotate your seed pair — this reveals the previous server seed and shows the SHA-256 hash it was committed to before you bet.
- Find the nonce. Each bet on a seed pair has an incrementing nonce. Use the nonce of the exact Keno round you want to check.
- Paste & verify. Drop the server seed, client seed and nonce into the form above. Faircheck recomputes the drawn numbers and confirms the seed hash matches.
The Keno formula
Bytes from HMAC-SHA256(serverSeed, `clientSeed:nonce:round`), converted to floats and mapped per game. The server seed is committed as a SHA-256 hash before the bet and revealed when you rotate seeds.
Ten floats are drawn from the HMAC-SHA256 stream.
Each float selects a tile from the remaining pool of forty, producing ten distinct numbers.
The draw is identical for everyone holding the same seed pair and nonce.
