With the rise of AI-generated content, it's getting harder to verify what's real. Can we use Web3 & Blockchain to create a "digital provenance" for media? I’m curious if we can cryptographically sign photos at the source (the camera) and track their metadata to prove they haven't been tampered with by AI tools.

Do you think hardware manufacturers like Sony or Canon will actually agree to bake these cryptographic signing keys directly into their camera sensors at the factory level?
It’s also a great way for creators to prove ownership and collect royalties. If the "source" is verified, the licensing becomes much easier to automate.
Exactly, Scott. Linking provenance to a wallet address allows for immediate micro-payments whenever an image is used commercially, which is a win for both trust and artists.
This is one of the most exciting use cases for the intersection of these two technologies. By anchoring a hash of the original media into a ledger, any subsequent edit would change the hash, immediately alerting the viewer that the content is no longer original. I worked on a prototype for this in 2024 using the C2PA standard. The beauty of a Web3 & Blockchain solution here is that it doesn't rely on a central "truth" authority like a social media giant. Instead, the proof is embedded in the math of the blockchain itself, making it globally verifiable and resistant to censorship.
Larry, that’s the billion-dollar question. Some manufacturers are already joining the Content Authenticity Initiative, which is a great start. The challenge is making it a global standard rather than just a niche feature. If only high-end professional cameras have this, the "average" photo on the internet will still be suspect. We need a world where even smartphone cameras have a secure enclave for signing images, creating a transparent web of trust that protects consumers from misinformation.
