From 0 to ZK Concept Bites #7#: Verifiable Provenance Last time we covered the redundancy problem, how Ethereum's "everyone verifies everything" model creates the bottleneck that real-time proving solves. This time, a different ZK property: provenance. 🛡️ Provenance is the ability to prove where something came from and what happened to it along the way. The clearest live example is Brevis Vera. Modern flagship cameras (Sony, Leica, Nikon, Canon) ship with C2PA, a standard that cryptographically signs every photo at the moment of capture. The image carries a verifiable record of which device produced it. Any edit afterwards breaks that signature. Vera fixes the break. Each edit between capture and publication runs inside Pico zkVM, which generates a proof that the edit was legitimate. The result is an unbroken chain from camera sensor to whatever image you're looking at. Provenance shows up beyond images too. Anywhere you need a verifiable chain of custody, this is the property doing the work. We just added a section on this to Part 4 of the refreshed From 0 Knowledge to Zero Knowledge series.
