Inspiration

With the rise of AI-generated images, it's important to distinguish between camera-taken photos of the real world and generated images.

What it does

Stores photos you take with our camera app on the blockchain. Stored on the backend as Cartesi notices.

We built it using React Native, Web3js, and Cartesi!
