CryptoPlace is a blockchain-based art experiment inspired by Reddit's /r/place. Users collaborate on a 100x100 pixel canvas where each pixel's color is determined by Bitcoin transactions.

The project is for cryptocurrency enthusiasts and digital artists interested in exploring decentralized, community-driven creative experiences.

It's a static site with WebRTC and peer-to-peer. Why? I wanted r/place (Reddit canvas where users collaborate on a pixel grid), but with proof of work. This is my progress so far. It's a WebRTC app with peer to peer connectivity that forwards the best hashed values to other users, which verify them, display them and pass them on. There are many many improvements to be done (especially I should probably…
