Verify a round
Every round's crash point is fixed before betting opens and published afterwards. Paste the seeds from a finished round and this page recomputes the result. The calculation runs entirely in your browser — nothing is sent to our servers, because a verifier that asks us to confirm our own result verifies nothing.
How it works
- 1. Commit. Before a round opens we publish
SHA256(serverSeed). We cannot change the seed afterwards without breaking that hash. - 2. Your entropy. The crash point is derived from
HMAC-SHA256(serverSeed, clientSeed:nonce). You contribute the client seed, so we cannot pick a seed that produces the outcome we would prefer. - 3. Reveal. After the crash we publish the server seed. Hash it yourself and compare it to the commitment you were shown before you bet.
- 4. Chain. Each seed hashes to the one revealed before it, all the way back to a head hash published before the first round was ever played.
