roles within a single product ecosystem
Case 02 / Art-tech startup
ART KEY
Virtual halls, a catalog, sales, and a verifiable history of ownership — in one platform.

connected data models in the domain architecture
art formats brought together in one storefront
continuous history of an artwork from artist to collector
Product idea
Product architecture
The platform brings four roles together on a shared data model: the artist gets a hall and a storefront, the collector gets a catalog and a verifiable history of artworks, the viewer gets access to exhibitions without geography, and the curator gets moderation tools.
Every artwork receives an Art Key — a digital certificate with a cryptographic chain of issuance and transfers.
Ecosystem
Roles in the ecosystem
Four roles with access control. A shared catalog, halls, communication, and a provenance model.
Artist
Creates a profile, publishes 2D and 3D artworks, builds their own hall, manages the display, and receives purchase requests.
Collector
Explores artists and halls, saves favorites, verifies the Art Key, contacts the artist, and records the transfer of an artwork.
Viewer
Browses exhibitions and the catalog without geographic limits, moving between the halls of different artists.
Curator
Reviews profiles and content, curates collections, and monitors catalog quality.
Virtual exhibition
Virtual halls
The artist configures the 3D hall in real time: changing the layout, the display, and the navigation. The viewer moves from hall to hall through doors — like in a physical gallery.



Art Key / Provenance
Provenance
A cryptographic chain of ownership: SHA-256 records the file's fingerprint, Ed25519 confirms the author's signature. The certificate can be verified independently of the platform.

Digital fingerprint
SHA-256 links the record to a specific file. Even the smallest change produces a different fingerprint.
Author's signature
Ed25519 confirms which key signed the issuance and prevents the record from being swapped.
History of ownership
Every transfer references the previous record. Removing or reordering a link mathematically breaks the chain.
Independent verification
The certificate, QR code, and exportable data let you verify an artwork's history outside the platform.
For the collector
The collector's journey
From the catalog — to the artist's profile, hall, certificate, and direct contact with the author.




- 01
Open an artist through the catalog, a curated selection, or a virtual hall
- 02
Examine a 2D artwork or an interactive 3D model
- 03
Verify the certificate and the continuity of the provenance chain
- 04
Send a purchase request and contact the artist
- 05
Receive the artwork along with a new transfer record
Product architecture
Stack and architecture
A monorepo: storefront, application, API, and typed contracts. A single data model for 3D, catalog, sales, and provenance.
Potential / Roadmap
Roadmap
Next — 3D sculpture and installations, curated selections, author verification, analytics, and an external timestamp anchor for provenance records. The storefront, dashboards, content, transactions, and the trust layer are separated architecturally — each module evolves independently.
