Earthline

The Sovereign Memory Layer ›

Structured, decentralized, built to last

Earthline is a research prototype and 3D knowledge interface exploring how public knowledge can become easier to discover, preserve, verify, and understand across generations.

The web is fragile. Links break, platforms disappear, and years of work can vanish with them. Earthline is a structured, decentralized archive designed to keep digital knowledge legible, linked, and recoverable over time.

At its simplest, Earthline is like Wikipedia × a globe of Earth × Sketchfab: the linked structure of an encyclopedia, the navigable feeling of an Earth browser, and the spatial presence of a 3D archive.

Earthline is a response to the platform drift that threatens our collective memory. This is not another feed or another closed platform. It is a stable, peer-to-peer memory layer for artifacts, ideas, and connections.

Earthline supports a more sovereign web by giving builders, archivists, educators, institutions, and the historians of tomorrow a way to publish and preserve knowledge with durable structure, clear provenance, and long-term recoverability. By reducing centralized dependency, it helps ensure that artifacts and connections remain with the people and communities who create them.

Who is this for?

Builders: Publish 3D work, knowledge objects, and media with provenance that stays attached. Build on a foundation where your portfolio does not vanish when a hosting platform changes its terms.
Archivists: Preserve community collections, family archives, and cultural records in a form designed to outlast the platforms of the present.
Researchers and educators: Navigate a richer, linked archive where knowledge is organized by structure and intent instead of by algorithms.

Build & Publish ›

For creators and technical builders

Publish 3D artifacts, scenes, and knowledge objects in a form that keeps context attached. Earthline is built so media, metadata, and provenance can travel together instead of being scattered across platforms and broken links.

Under the hood, Earthline uses structured packaging and stable addressing so work can be placed, found, and recovered later. The goal is simple: what you publish should still make sense in the future, even if the original viewer, store, or platform changes.

As a prototype, Earthline also asks whether placing knowledge into a navigable spatial environment can help people discover relationships between articles, places, events, artifacts, and source records.

Action: Package work in a durable format and anchor it to a stable reference point.
Technical path: Use Earthline formats such as Triplex and GIDs when you need structured, portable publishing.

Preserve & Protect ›

For archives, collections, and long-term stewardship

Earthline is built for long-term preservation. Instead of relying on a single platform or database, it uses structured packaging, content addressing, and repeatable snapshots to keep records stable, verifiable, and portable over time.

That can mean public knowledge, local history, or a private family archive. The point is the same: preserve material in a form that can be checked, traversed, and carried forward.

Every day, citations break, pages disappear, and the evidence behind a link can vanish. Earthline explores how source context, archive status, provenance, and preservation records can be made visible before public trust quietly fails.

Action: Preserve collections as repeatable snapshots that can be reviewed and carried forward over time.
Verification: Check records through readable metadata, visual inspection, and cryptographic integrity.

Connect Intentionally ›

For trusted circles and deliberate sharing

Earthline is not built around feed mechanics. It is built for intentional connection: smaller circles, clearer trust, and ways of sharing that do not depend on algorithmic visibility.

The aim is to let people keep what matters close, carry identity and access with them, and share knowledge deliberately. Ownership, portability, and privacy should be part of the structure, not an afterthought.

Action: Share artifacts and access through trusted relationships instead of open-ended feed dynamics.
Privacy model: Use portable identity, bounded sharing, and consent-based access as core design principles.

Support & Sustain ›

For patrons, sponsors, and public stewards

Earthline is designed to be explored, but it also needs long-term support. Artifact Sponsorship gives patrons and institutions a way to help fund preservation in a form that becomes part of the archive itself.

Support is tied to durable records, physical prints, and public stewardship rather than disappearing into a generic donation flow. The goal is to connect cultural support with visible, lasting preservation. Join The Community and Make A Difference.

Action: Sponsor an early foundational artifact and help fund long-term preservation.
Experience: Follow the archive through the viewer, prints, exhibitions, and public installations as it grows.

Technical Documents ›

Specifications, reference materials, and implementation notes

Developers, preservation partners, and technical collaborators can find the working specifications, reference builds, and implementation notes at(email for URL) gateway.earthline.app.

Start with the core formats and addressing model to understand how Earthline packages media, links artifacts to structure, and preserves recoverable states over time. The documentation is there to help others inspect the system, build against it, and verify how it works.

The research layer will document what works, what fails, and what design patterns may help future public knowledge tools. Outputs may include prototype notes, mapping layers, usability findings, preservation workflows, and open research documentation.

Formats: Review core packaging, metadata, and addressing standards.
Implementation: Inspect reference builds and preservation workflows.
Integration: Build tools and pipelines that can publish into the Earthline system.
Research: Study how spatial discovery, provenance, and preservation status can make public knowledge easier to navigate and verify.

OHPN: The Open Heritage Preservation Network ›

Nonprofit stewardship and public trust

OHPN is the nonprofit stewardship layer that helps keep Earthline stable, auditable, and publicly accountable over the long term. It exists so preservation can outlive any one company, team, or phase of development.

Its work is organized around four pillars that help keep the archive online, legible, and trustworthy as tools, institutions, and generations change. Join The OHPN Discord.

Steward Nodes: support distributed operators, redundancy, and continuity planning.
Standards & Provenance: maintain public rules and verification practices for auditable artifacts.
Public Access: support libraries, classrooms, community nodes, and local preservation efforts.
Governance & Trust: provide transparent oversight so the archive remains a public good.
