The platform
The AerariumChain HUB is where the twins live: the registry of the collection, the scan pipeline with its quality control, a viewer that streams terabytes to any device, and a growing store of applications. Three families of services grow on top: CARE, SHOW and FUND.
Every artwork with its records, versions and full scan history: master files, attempts, approvals, blockchain notarization. Data imports from your existing systems.
Raw scans flow in from the field, get processed in the cloud and reviewed in the browser: OK/NOK with structured comments, version by version.
Full-resolution geometry and texture on a phone, a kiosk or a laptop. Progressive streaming: a multi-gigabyte master travels as a few dozen megabytes.
Applications for the museum install from the HUB store: scanner tools, site manager, totem interfaces, XR experiences. One click, connected to your twins.
Invite conservators, curators, external specialists and partners with granular roles. Everyone sees exactly what they should.
Open formats, export always available, connectors to national heritage systems. How the HUB talks to other systems →
Inside the HUB
The catalog
The collection lives as a working catalog: inventory numbers, versions, formats and dates for each artwork, with the twin one click away. What used to be a record card becomes something you can open, measure and reuse.
The viewer
Full resolution on any device: model layers, wireframe, annotations, light and material controls. A 5 GB master travels roughly like your favorite streaming movie, on an ordinary phone.
Gigapixel
Stitched captures of paintings and tapestries sit next to the 3D: each composite opens in a deep-zoom viewer that goes down to the single thread or brushstroke.
Publishing
Curated pages go straight from the HUB to visitors: artwork sheet, dimensions, inventory data and the twin itself, viewable in 3D by anyone you choose.
Three ways to use a twin
Diagnostics, comparison between scans over time, annotations, collaboration between specialists anywhere.
Explore CARE
Totems, XR experiences, 8K media for catalogs, certified 3D prints. The collection in front of people.
Explore SHOW
Fundraising built on the twin: campaigns, compliant digital collectibles, a way in for everyone who loves the collection.
Explore FUNDThe store
Every application installs from the HUB store already connected to your twins and your permissions: scanner tools for the field, totem interfaces, XR experiences, render makers, delivery connectors. One login for all of them. The store grows; your setup does not.
Security and sovereignty
The HUB runs on SweetHive, an infrastructure built for regulated, high-trust environments. The answer to the question every institution asks first, where does the data go, is structural, not a promise.
Every scan, model and derivative belongs to the collection's owner. We operate the platform; we acquire no rights, ever.
Access follows roles: conservators, curators and partners see only what they should. Nothing becomes public without an explicit decision, and sensitive works can stay visible to a restricted circle only.
European collections on EU infrastructure, US collections on US infrastructure: every country can have its own hosting, encrypted in transit and at rest, with residency guaranteed per region.
Each file's fingerprint is notarized on a public blockchain at capture: provenance and integrity you can show an insurer or a court.
Storage and processing can be pinned to the institution's own hardware, inside its own perimeter: the computing comes to the data, the data never leaves.
Dedicated deployments for public bodies: sovereign hosting, custom retention, and compliance with national heritage systems from day one. The connector layer →
Heavy computing should not be a privilege. The HUB routes every workload across three tiers, by sensitivity, latency and cost:
Sensitive, confidential work runs on machines inside the institution. Scope is enforced down to the hardware.
Non-sensitive heavy work, meshes, tiles, renders, bursts to a distributed network of independent nodes. Capacity grows with the network and unit costs keep falling: high-end computing stays accessible to small museums too.
Per workload: private only, network allowed, or automatic. The default keeps sensitive work at home. The full security model →
FAQ
The institution, always. Every scan, model and derivative belongs to the museum or to the owner of the artwork. AerariumChain operates the infrastructure and never acquires rights over the collection.
In the region the institution chooses: EU collections on EU infrastructure, US collections on US infrastructure, and every country can have its own hosting. Data is encrypted in transit and at rest, and institutions with stricter requirements can pin storage and processing to their own hardware.
Yes. Everything is private by default: people see only what their role allows, and nothing is published without an explicit decision. Sensitive works can remain visible to a restricted group only.
Yes. Full export in open formats, METS packages, meshes, TIFF pyramids, is always available. No lock-in, by contract and by design.
With dedicated deployments: sovereign or on-premise hosting, custom retention policies and compliance with national heritage regulations.
Every file's fingerprint is written to a public blockchain the moment it is captured. Integrity and provenance can be verified at any time, by anyone you authorize.
