Specimens: the rock carries its own story.
A mineral specimen's value depends on information outside the stone: source, history, ownership, documentation. Watermelon Auth gives the object a cryptographic credential and connects it to the trusted record.
The Richard's Minerals showcase
The live implementation at verify.melon.tips runs a mineral collection where each specimen carries a secure NFC credential linked to its digital record.
Authentication
Tap the specimen and verify the credential is real, present, and current. A photo or copied link cannot stand in for the tap.
Provenance
Append-only history, photographs, source attribution, ownership and custody records. Attached to the object, not a spreadsheet.
Collectibles and art
Each piece is a distinct credential with its own record. Authenticity and history travel with the object.
Scientific specimens
Research collections get tamper-evident identity plus the ability to attach data, papers, and custody history.
The object carries the credential
The tag stays with the thing; the platform carries the trusted context. Swap the tag and the record no longer matches.
