Succinct Labs shipped ZCAM, an iPhone app that cryptographically signs photos and video at capture, hashing the actual pixel data and binding it to the device. Anyone can verify the file came from a real camera, not an AI tool.
This is the early shape of a category that's about to explode: verification-as-a-service and authentication-as-a-service. As generative models close in on perfect synthetic media, provenance stops being a nice-to-have and becomes infrastructure.
Hashes, signatures, attestation chains, on-device proofs.
Every platform that hosts user-generated content will need a verification layer within a few years. Builders should be looking at this primitive now.
