One year ago today, we publicly introduced Keychat. The letter metaphor helped many people understand what Keychat is all about. Today, Keychat is officially live — and even more focused on serving Bitcoiners. “Keychat is the super app for Bitcoiners. Autonomous IDs, Bitcoin ecash wallet, secure chat, and rich mini apps — all in Keychat. Autonomy. Security. Richness.” This is our first time building a Bitcoin-related app, and as Bitcoiners, we’re truly enjoying it. Thank you for sharing our notes, helping more people discover Keychat, and giving us valuable feedback. We need this kind of support. View quoted note →

“WWDC 2007, SAN FRANCISCO—June 11, 2007—Apple® today announced that its revolutionary iPhone™ will run applications created with Web 2.0 Internet standards when it begins shipping on June 29. Developers can create Web 2.0 applications which look and behave just like the applications built into iPhone, and which can seamlessly access iPhone’s services, including making a phone call, sending an email and displaying a location in Google Maps. Third-party applications created using Web 2.0 standards can extend iPhone’s capabilities without compromising its reliability or security.”

Why isn’t Keychat a web app? Web apps and PWAs can’t reliably support Signal or MLS protocol because those protocols depend on secure, persistent local storage and uninterrupted processing to keep cryptographic state (double-ratchets, MLS group keys and membership) up to date, whereas browsers only offer volatile storage and can’t guarantee continuous execution—so keys and session data risk being lost.

Keychat users first establish an online Me (ID + Wallet) they fully control, and then chatting and browsing become their primary activities.

Agreed. We’ve been doing all our text-based development communication on Keychat ever since it became usable. View quoted note →
