A passport is only worth the proof behind it.

• 

  SuiThe passport record

  Each published passport gets an object on Sui holding the hash of its evidence bundle and the moment of publication. Change one field and the hash no longer matches. That's the whole point.

  • One object per passport
  • Every version kept
  • Public, cheap to check
• 

  WalrusEvidence and storage

  Certificates, geospatial files, lab reports and build records live as Walrus blobs. The passport references the blob id, so evidence stays retrievable without being pasted into a chain transaction.

  • Blob ids referenced by the passport
  • Content-addressed, so nothing silently swaps
  • Survives supplier turnover
• 

  SealEncrypted and restricted claims

  Pricing, due diligence declarations and audit files are encrypted with Seal. Keys are released only to wallets that satisfy the access policy, so a public record can still hold private commercial detail.

  • Field-level encryption
  • Access policy held on chain
  • Buyer view without a data room

From evidence to anchor.

1. 01
   Collect

   Suppliers submit certificates, geodata, lab results and build records against a claim.

2. 02
   Grade

   Each claim gets a level from L0 to L5 based on who attested it and what backs it.

3. 03
   Bundle

   Public and encrypted evidence are packaged, hashed and written to Walrus.

4. 04
   Encrypt

   Buyer-only fields are sealed against an access policy before the bundle leaves the platform.

5. 05
   Anchor

   The bundle hash is committed to a Sui object, timestamping the passport as published.

6. 06
   Serve

   The QR code resolves to the passport, and anyone can re-hash the bundle to check it matches.
