Provably-fair dice
You don’t have to trust us.
You can check.
Most dice games ask for your trust. Orion gives you proof — the same commit-and-reveal cryptography used to keep online systems honest.
- 01Step 1
Commit
Before the first roll, the server generates a secret seed and sends you its SHA-256 hash — a sealed promise it can't take back.
sha256(seed) → 9f2a…c7 - 02Step 2
Roll
Every die is derived from that seed with HMAC-SHA256. The outcome was fixed at commit time — no roll can be re-drawn to help anyone.
roll = HMAC(seed, nonce) - 03Step 3
Reveal & verify
At the end, the server reveals the seed. Your device re-hashes it and checks it against the opening commitment. Match? Provably fair.
sha256(seed) == 9f2a…c7 ✓
Rolls are computed by an isolated backend and validated by a separately-tested rules engine. No third-party services touch your game.
