Verify Artwork Authenticity
Every physical masterpiece consigned with Tigaketuk is affixed with a tamper-evident, serialized hologram registered on our archival cryptographic ledger.
OUR GUARANTEE
The Three Knocks Standard
A multi-layered physical and digital protocol ensuring provenance and ownership integrity.
1. Serialized Hologram
A custom optical hologram with micro-engraved serial is affixed by our specialists: on the reverse frame of flat works or on the base/underside of 3D sculptures and ceramics. Tamper-evident foil destructs if removed.
2. Cryptographic Digest
Each certificate is paired with a unique SHA-256 digital fingerprint binding the artwork's dimensions, physical condition report, high-resolution photography, and inspector sign-off into an immutable registry record.
3. Permanent Provenance
When a lot is hammered down, title transfer and certificate updates are logged. Future buyers, appraisers, and institutions can verify authentic provenance at any time without middleman ambiguity.
