Fair verification
Every pack open uses a Provably Fair algorithm. Results are committed via server seed hash before opening and can be independently verified afterward.
Algorithm overview
- Each open uses a unique server seed (serverSeed) and records its SHA-256 hash (commitment).
- Each user has a client seed (clientSeed) and an incrementing nonce (open count).
- Compute rollDigest = HMAC-SHA256(serverSeed, clientSeed:nonce).
- Take the first 8 hex digits of rollDigest and map to a roll value from 0–100.
- Map to a specific item using the published probability ranges for the pack.
- After opening, the order reveals serverSeed. The verification page shows commitment hash, commitment time, and settlement time (millisecond precision) for instant local verification.
- The site also maintains audit cycle seeds (rotated 每 7 天). The current cycle hash is shown below; historical cycles are archived after rotation.

On any open result, battle record, or order detail, click "Provably fair" to view that order's clientSeed, nonce, roll value, and verification result.
You can also verify by clicking an order number in Transactions.
