Deliverables:

• See linked pull requests
• First successful CoinJoin over native WebSocket on RegTest!

There are 4 windows here:

1. DashJoin WebSocket client Full In-Browser CoinJoin Demo #1 (front)
2. DashJoin WebSocket client Wallet UI - 3rd Party Integration: CrowdNode.js Updates #2 (one back)
3. WebSocket Proxy to DashCore (background)
4. ignore: top right (code window)

This shows a successful CoinJoin process, adapted to using native JavaScript WebSockets, ws, and a light proxy service to bridge to tcp.
