Using WebTorrent trackers for purposes other than torrents
summary
Library P2PD uses WebTorrent trackers as a signaling channel to create browser-to-browser WebRTC apps, demonstrated by a multiplayer drawing game and a local file‑share that runs entirely in the browser with no backend. It originates from a hackathon project that won second prize in 2020 and later aims to be a decentralized Wikipedia proxy for censored regions. Implementation relies on hybrid client bridging to BitTorrent; it works reliably on Firefox but broke on Chrome v110 (Jan 2023).
