First build of the content provenance ledger: the C2PA specification and its embedding rules, the conformance programme and trust list, JUMBF, JPEG Trust, the IPTC digital source type vocabulary, nine platforms and model providers, seven laws and bills, and four open questions.

Last updated 15 September 2026. Every record re verified 15 September 2026. The ledger is checked monthly, first Monday, and the same day for any C2PA specification release.
