AXIA.TRUST.V1 · SPECIFICATIONS

Protocol Specifications

Versioned, normative specifications that define the Axia trust infrastructure. Public, machine-readable, and stable.

AxIA Transparency Package (ATP) v1

Signed, JCS-canonical evidence envelope. Vendor-neutral: provenance, watermark, disclosure, receipt, identity, capture and more.

Trust Semantics

Definitions, assertions vs evidence, boundaries, transitions.

Cryptographic Profile

SHA-256, Ed25519, Merkle, canonicalization, timestamping.

Verification Receipt v1

Frozen wire format, canonical payload, signature scope, lifecycle semantics.

Event Taxonomy

Lifecycle event types, visibility, evidence class & strength.

JSON Schemas

Machine-readable Draft 2020-12 schemas for the protocol.

Axia Signals

Experimental probabilistic signals layer. Strictly separated from Verify.

Identity Governance

Signer types, delegation, policies. Governed vs ungoverned provenance.

Trust Boundaries

Machine-readable scope of what Axia can and cannot verify.

Compatibility Guarantees

What may change additively vs. what requires a major-version bump.

Protocol Changelog

Additive, breaking, deprecation, freeze events on the public surface.

Signed Tree Head v1

axia.sth.v1 — timestamped, signed root commitments for gossip and offline verification.

Merkle Proofs

Inclusion + compact consistency proofs and the axia.merkle.v1 hashing convention.

Witness Governance

Allowlist, lifecycle (active/suspended/revoked/compromised), weighted quorum policy.

Origin Layer

First-seen + derivative content detection via SHA-256 + perceptual hashing. Strict semantics, no copyright claims.
