Webtops, also known as web desktops, offer the promise of a desktop-like experience within a web browser, making it possible to run applications and manage files without needing traditional operating systems. This innovation has the potential to transform how we use devices, making them more versatile, accessible, and flexible. One of the most notable implementations in this space is Puter. This cloud-based operating system stores data on a backend server, ensuring user data is accessible from any device.

The Signal Protocol has become the gold standard for end-to-end encrypted messaging, powering applications like WhatsApp, Signal, and Facebook Messenger. But what happens when you want to implement the same level of security in a truly peer-to-peer environment—one without centralized servers managing pre-keys and message routing?

In this article, we'll explore how to adapt the Signal Protocol's X3DH (Extended Triple Diffie-Hellman) key agreement and Double Ratchet algorithm for direct peer-to-peer communication over WebRTC. We'll discuss the challenges unique to P2P environments, propose practical solutions, and walk through a browser-based JavaScript implementation that maintains the security guarantees of the original protocol.

As a proof-of-concept app, id like to explore social media functionality to our app. the app is already able to create p2p connections and share multimedia. the next step is to add a social media UI to the app. this mode will allow users to share photos and videos with their peers.
