How Our Provably Fair System Works
Three phases to guaranteed fairness — verified by you.
Phase 1 : Pre-Purchase
Is This Pack Fair?
All cards locked and verified before you buy — no trust required.
- Shuffle all card positions using a cryptographically secure randomizer
- Generate unique "fingerprint" (Merkle root) of entire pack
- Commit to server seed by publishing its hash
- Publish commitments publicly — unchangeable after
Phase 2 : Post-Draw
Was My Draw Fair?
Your draw is proven fair — click to verify in one tap.
- Your browser generates unique client seed (private to you)
- Combined with committed server seed = your draw number
- System reveals card with cryptographic proof it existed before
Phase 3 : Post-Sellout
Can I Verify Everything?
Full transparency — all data revealed, all proofs verified.
- Instant check: Click "Verify" to confirm authenticity
- Full audit: After sellout, all secrets revealed
- External tools: Download data for independent verification
