Exploring the world of decentralized networks with WebRTC
summary
WebRTC lets browsers open encrypted peer links without plugins using data channels API like WebSocket, works today in Chrome and Firefox on desktop and mobile, and uses ICE with STUN for public IP discovery and TURN as a costly relay fallback. WebTorrent shows browsers can seed content by converting blobs into torrents and announcing hashes on a DHT but cannot speak native BitTorrent peers and browsers cap connections (~150), so hybrid relays or incentives are required for reliable large scale use.
