The 7 layers of verifiable trust for digital and AI-generated content.

Axia is not a detector. It is the operational trust ledger publishers, platforms and auditors use to mark, verify, monitor and audit content across its full lifecycle.

CONTENT LIFECYCLE

Seven layers

Identity

Who is publishing the content.

Attestation

Cryptographic attestation binding identity to content.

Provenance

Where the content comes from and what it derives from.

Integrity

Whether the content has been altered since signing.

Transparency

Public, append-only, third-party verifiable record.

Trust Monitoring

Continuous lifecycle events and operational signals.

Auditability

Reconstructable historical evidence and audit exports.

Evidence preservation

Every layer is append-only. Signatures, lifecycle events, Merkle checkpoints and trust status snapshots are preserved indefinitely and never overwritten. Each event is tagged with a verification profile (axia.trust.v1) so historical proofs remain reconstructable as the protocol evolves.

Alignment with EU AI governance principles

The 7 layers map naturally to the operational requirements emphasised by AESIA across the AI Act guidance — automated logs, post-market monitoring, traceability, technical documentation and integrity. Axia provides the cryptographic and operational primitives; obligations remain with the operator.

Build on the trust ledger

Sign content, monitor its lifecycle and export auditable evidence — all on a single open infrastructure.
