Multiplayer games, a chat, a paint canvas, a jukebox and a tamagotchi with Filecoin Onchain Cloud as the only backend. No server anywhere.
An arcade that runs entirely in the browser. Every move, chat message and painted pixel is a small signed file stored in a data set, and each page rebuilds the game by reading those files back in order. There is no database and no server to take down.
Some games need a wallet on the calibration testnet. The paint canvas and the chat work without one, and anyone with a link can watch a game.
