Provably Fair Verification

Verify that your pack opening results were determined fairly using cryptographic proofs.

How It Works

Before you open a pack: The server commits to a secret seed by showing you its SHA-256 hash. You provide your own client seed. Neither party can change their seed after commitment.

After you open: The server reveals its seed. You can verify:

The revealed server seed hashes to the committed hash
The nonce was correctly derived from the hash + your client seed
The entropy proof matches the combined inputs
This entropy determined your card selection

Enter Verification Data

Server Seed (revealed after pack open)

Client Seed (your seed from the pack opening)

Server Seed Hash (committed before pack open)

Server Nonce (optional, for extra verification)

Entropy Proof (optional, for extra verification)

Current Server Configuration

The current server seed hash is displayed on the gacha page before you open a pack. After a pack is opened, the server seed is revealed in the proof panel.
