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.

The physical thing carries the credential. The platform carries the trusted context: provenance, photographs, and history attached to the object itself.
