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.

Roles in the ecosystem

Four roles with access control. A shared catalog, halls, communication, and a provenance model.

01

Artist

Creates a profile, publishes 2D and 3D artworks, builds their own hall, manages the display, and receives purchase requests.

02

Collector

Explores artists and halls, saves favorites, verifies the Art Key, contacts the artist, and records the transfer of an artwork.

03

Viewer

Browses exhibitions and the catalog without geographic limits, moving between the halls of different artists.

04

Curator

Reviews profiles and content, curates collections, and monitors catalog quality.

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.

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.

01

Digital fingerprint

SHA-256 links the record to a specific file. Even the smallest change produces a different fingerprint.

02

Author's signature

Ed25519 confirms which key signed the issuance and prevents the record from being swapped.

03

History of ownership

Every transfer references the previous record. Removing or reordering a link mathematically breaks the chain.

04

Independent verification

The certificate, QR code, and exportable data let you verify an artwork's history outside the platform.

The collector's journey

From the catalog — to the artist's profile, hall, certificate, and direct contact with the author.

Stack and architecture

A monorepo: storefront, application, API, and typed contracts. A single data model for 3D, catalog, sales, and provenance.

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.

ART KEY — infrastructure for an independent art market: halls, a catalog, sales, and a verifiable history of artworks.
