Core Concepts: How Token Guard Works

"Understand the foundational technologies and methodologies behind Token Guard, from Bi-Party Validation to Scroll L2 Blockchain."

Core Concepts

Token Guard is more than just a database; it is a trust infrastructure. To fully appreciate how we protect your collection, it is important to understand the four pillars of our technology.

/1. The Digital Product Passport (DPP)

At the heart of Token Guard is the Digital Product Passport (DPP). This is a secure, digital record that exists on the blockchain and is inextricably linked to your physical watch. Unlike a simple digital image, a DPP contains:

  • Cryptographic Proof: A unique hash of the watch's serial number.
  • Decentralized Metadata: Technical specs and images stored on IPFS.
  • Transaction History: A permanent log of certificate transfers and service attestations.

/2. Bi-Party Validation

Trust should never rely on a single source. Token Guard utilizes a Bi-Party Validation protocol. Before a certificate is minted, it must be verified by:

  1. Brand/Database Match: Ensuring the serial number exists in official manufacturing archives. Brand data is hashed and protected; third parties never access the archives directly.
  2. Expert Human Review: A physical inspection by a qualified watchmaker who can append lifecycle data without viewing brand archives.

/3. Scroll L2 Blockchain

To ensure that your certificates are secure for decades, we use the Scroll L2 blockchain.

  • Security of Ethereum: Scroll is a zkRollup that inherits the massive security of the Ethereum mainnet.
  • Speed & Efficiency: Transactions are processed instantly and with minimal environmental impact.
  • Immutability: Records are append-only; status updates are added, never overwritten.

/4. Immutable Provenance

Provenance is the "Chain of Custody" of an object. In the luxury market, clear provenance consistently improves buyer confidence and resale outcomes. Token Guard automates this by recording every significant event in a watch's lifecycle—from its first certification to its tenth sale—on the blockchain. This creates a "Digital Heritage" that stays with the watch forever.

/Conclusion

By combining these technologies, Token Guard restores the "Original Truth" of luxury goods. Ready to put these concepts into practice? Learn how to add your first watch.
