Content provenance infrastructure

HessianHeadless CMS

A headless document platform for teams that need digital content to stay portable, auditable, and independently verifiable after it leaves the publishing system.

Signed Documents

Ed25519 provenance

Every published record can carry a cryptographic signature tied to a workspace key.

Portable Verification

Resolve and validate

Downstream systems can verify records from a public key directory without the editor.

Standards Path

C2PA-compatible export

Hessian records are designed to travel into broader content authenticity workflows.

publish(document)
  -> signed_provenance
  -> verifier.valid = true

Proof Flow

Content moves. Trust travels with it.

Hessian separates the editorial workflow from the verification layer, giving publishers a developer-friendly way to create, sign, distribute, and audit digital assets.

Create

Model editorial assets as structured documents instead of trapping them in a page builder.

Sign

Attach provenance at publish time so authenticity is part of the content record itself.

Publish

Deliver the same trusted content to sites, newsletters, agents, archives, and APIs.

Verify

Let partners, auditors, and customers validate the signature trail independently.

Verification Layer

Built for teams that cannot afford content ambiguity.

Hessian gives developers a neutral provenance layer that fits into existing content systems, AI-assisted publishing flows, and compliance review paths without forcing everything into a closed editor.

Headless by default

Content is available through APIs first, so teams can publish anywhere without rewriting trust logic.

Cryptographic chain of custody

Signed provenance records make authenticity traceable after content leaves the CMS.

Lineage-aware records

Revisions and derivative assets can preserve history without mutating the original record.

Operator-controlled keys

Workspaces sign under explicit key IDs that can be rotated while preserving historical verification.

Authenticity does not have to end at publish time. The receipt can travel with the content into partner systems, archives, and downstream customer experiences.

Use Cases

A practical trust layer for the AI content era.

Content is cheap to generate and expensive to trust. Hessian is built for teams that need provenance to be enforceable, portable, and easy for developers to adopt.

AI-assisted publishing workflows that need disclosure and provenance.

Brand, media, and newsletter teams that syndicate content across channels.

Platforms that need a neutral verification layer instead of vendor lock-in.

Enterprise document flows where auditability matters after export.
