Decision

What the current evidence supports

Human editorial judgment · 2026-06-28

Track; not yet

Why
The protocol is well-architected and infrastructure-compatible, with early hardware (Sony IBC 2025 camera, Pixel 10) signing, but verification reach is immature, real-world C2PA coverage is sub-1%, and quantified overhead is undocumented — premature for production reliance.
Next
Monitor C2PA-aware player support and a real production deployment with measured latency/bandwidth; revisit when at least one mainstream player verifies live segments end-to-end.
