C2PA.ai - The Provenance Brief

Issue #12 · Mar 4, 2026

Adoption

Sony rolls out C2PA firmware to three more Alpha bodies

The a7 IV, a7C II, and FX3 now support native Content Credentials. Sony is the most aggressive of the big three in expanding beyond flagships.

Policy

SB-1047's successor includes specific language on content provenance. If passed, it would be the strictest US state law on AI content labelling.

Technical

The core Rust library now handles remote manifest retrieval more gracefully, with configurable timeout and fallback behaviour.

Deep Dive
