The Coalition for Content Provenance and Authenticity has marked its fifth anniversary with over 6,000 members and affiliates now actively using Content Credentials. The milestone coincides with the release of Content Credentials 2.3, the latest version of the open standard.
The 2.3 specification introduces live video provenance - the ability to sign video content in real time during capture or broadcast. This extends C2PA beyond still images and pre-recorded media into live streaming, a capability developed with input from broadcasters and streaming platforms. The update also makes it easier for creators to attach provenance data to their work and provides audiences with greater clarity on file history.
From six founders to six thousand
C2PA launched in February 2021 with six founding members: Adobe, Arm, BBC, Intel, Microsoft, and Truepic. Five years later, Content Credentials underpin provenance features across major platforms enabling millions of users to attach verifiable metadata to photos, videos, and other media.
The growth has been driven by a convergence of factors: the rise of AI-generated content, the EU AI Act's labelling requirements, and the adoption of C2PA by hardware manufacturers (Nikon, Sony, Canon, Leica, Google) and AI platforms (OpenAI, Adobe, Google, Stability AI). The Conformance Programme launched in late 2025 added a formal trust layer to the ecosystem.
What 2.3 changes
Beyond live video, the 2.3 specification includes improvements to how provenance data is structured and displayed. The release follows the formal launch of the Conformance Programme, which ensures implementations are secure and interoperable. Together, these developments mark a transition from specification development to scaled deployment - the standard is mature, the tools are available, and the regulatory framework is in place.
