Photoshop's patch tool is not a substitute; its positioning is quite clear.

BlockBeats reports that Brevis has officially launched the image provenance tool Brevis Vera, now open to all users. After capturing with a C2PA-supported camera/phone, users can edit in Vera and generate a zero-knowledge proof file that can be independently verified in the browser, proving the source and processing chain without revealing the source media or editing privacy. The full version introduces a zero-knowledge proof mechanism into the C2PA protocol stack, serving as a complementary primitive to editing tools like Photoshop, rather than a replacement.
