HuggingFace just passed $1,000,000 in sales for Microduck, which uses Nostr.
How does Microduck use Nostr? Essentially "invisible plumbing".
Microduck is Hugging Face's new $399 open-source biped duck robot (announced yesterday). Its multiplayer ghost feature, where you race/share sessions with other people's robots or sims, runs on Trystero, a serverless WebRTC library. Trystero needs a signaling network to do peer discovery without running servers, and it uses Nostr public relays.
