The Public Ledger and Privacy
AutographChain utilizes public blockchain technology (Polygon/Ethereum) to ensure immutability. It is critical to understand that data anchored to a public blockchain is, by definition, public and permanent.
What goes on-chain:
- Cryptographic hashes of signatures/documents.
- Authentication metadata (Dates, Authenticator IDs).
- Wallet addresses holding the Digital Twin NFT.
- Transaction history of the Digital Twin.
What stays off-chain:
- Your personal identifiable information (Name, Email, Physical Address).
- Credit card or payment information.
We strongly recommend using dedicated wallet addresses for AutographChain assets to maintain pseudonymity.

Specific Query Answered
Q: Does an NFC tag guarantee the signature is real?
A: No technology can perform the initial expert human appraisal. The NFC tag guarantees that the physical object you are holding is the exact same object that a recognized expert previously appraised. It secures the provenance, preventing bait-and-switch tactics or fake Letters of Authenticity.
