Our Digital Certificates

Tagsmart pioneered the use of transferable physical Certificates. Our provenance management service now includes Digital Certificates are issued as counterparts to physical Certificates. They provide additional provenance verification and can also be shared by email - for example, where your collector requires an immediate Certificate document while their physical document is in the post. You can also keep and print an additional copy for your own records.

Each Digital Certificate is signed using the globally accepted ESIGN standard, is stored in the work’s provenance record and carries multiple security features. A link on the Certificate enables the holder to verify both the Digital and Physical documents.

KEY FEATURES

Security

Each Digital Certificate is presented as a read-only, digitally signed PDF, hashed onto the Polygon blockchain. The keeper of the artwork record can request a reissue at any time: this invalidates any previous digital Certificate but does not change the status of its physical Counterpart unless required. Revoking or replacing a physical Certificate will re-generate its digital counterpart.

The Artwork

Core artwork information and image, supplied by the artist or a third-party specifically authorised by the artist to issue the Certificate on their behalf, is featured along with selected artwork information. A thumbnail of the associated physical Certificate is also included.

Signature & Hash

Every Digital Certificate is electronically signed by the Tagsmart Registrar who confirms that it faithfully represents the physical Certificate issued by the artist or by the third-party specifically authorised by the artist. A hash of the associated physical Certificate ID is included.

Blockchain filing

Digital Certificates are currently uploaded to the work’s provenance record and linked to transaction on the Polygon blockchain.
