Quick Start

This guide walks you through the key concepts of Galileo in 5 minutes. By the end, you'll understand how products are identified, tracked, and transferred using the standard.

1. Product Identity

Every luxury product in Galileo has a unique Decentralized Identifier (DID):

did:galileo:01:00614141123452:21:ABC123DEF456

This DID encodes the GS1 GTIN (product type) and serial number (individual item). It's globally unique, resolvable, and not controlled by any single party.

2. Digital Product Passport

Each product has an associated DPP containing its attributes, provenance, and compliance data:

{
  "@context": "https://vocab.galileoprotocol.io/contexts/galileo.jsonld",
  "@type": "IndividualProduct",
  "@id": "did:galileo:01:00614141123452:21:ABC123",
  "gtin": "00614141123452",
  "serialNumber": "ABC123",
  "name": "Capucines MM",
  "brand": {
    "@type": "Brand",
    "name": "Maison Heritage",
    "@id": "did:galileo:brand:maison-heritage"
  },
  "materials": [
    { "type": "Leather", "origin": "France", "certified": true }
  ],
  "carbonFootprint": {
    "value": 12.5,
    "unitCode": "KGM"
  }
}

3. On-Chain Ownership

Ownership is recorded on an EVM blockchain using ERC-3643 tokens:

  • One token = one physical product (1:1 ratio)
  • Transfers require identity verification (KYC/KYB)
  • Compliance modules enforce jurisdictional rules

4. Lifecycle Events

Every significant event in a product's life is recorded:

  • Creation — Product manufactured
  • Commission — Serial number assigned
  • First Sale — Initial retail purchase
  • Repair/MRO — Maintenance events
  • Resale — Secondary market transfers
  • Decommission — Product retired

5. Resolution

Anyone can look up a product using its GS1 Digital Link:

https://id.galileoprotocol.io/01/00614141123452/21/ABC123DEF456

The resolver returns different views based on who's asking: consumers see authenticity info, brands see full history, regulators see compliance data.
