A good writer avoids overusing adjectives; Keychat follows the same principle in its introduction, using fewer adjectives and focusing instead on explaining its mechanisms.

"Simplex Chat: The first messenger without user IDs Other apps have user IDs: Signal, Matrix, Session, Briar, Jami, Cwtch, etc. SimpleX does not, not even random numbers. This radically improves your privacy." It isn’t IDs that compromise privacy, but the practice of using IDs as addresses. The receiving address and the sending address must be kept separate from the ID, and both addresses should be continuously rotated. View quoted note →

We will keep optimizing the Keychat browser. Our goal is for the Nostr web client—Jumble @Jumble combined with Keychat browser to match or even surpass the user experience of native Nostr clients.

No one understands Bitcoin’s current price. Those uninformed about Bitcoin can’t understand how a single coin could be worth $110,000. Bitcoiners can’t understand why it’s worth only $110,000 now.

It’s time for some nonlinear reading.

Keychat encourages users to use multiple IDs, so it minimizes ID-switching friction as much as possible. At the top of the Chat page are the user’s IDs; tapping a different ID shows the chat-room list for that ID.

NIP-4 DMs will gradually be replaced by NIP-17 DMs. Eventually, only NIP-17, the Signal protocol, and the MLS protocol will remain. View quoted note →

Many people are curious about the difference between Keychat and White Noise. Keychat encrypts one-to-one chats and small groups with the Signal protocol, while large groups use MLS encryption. White Noise, by contrast, encrypts every message solely with MLS. Think of each message as a letter: both Keychat and White Noise rely on OpenMLS to encrypt the content inside. The main distinction lies in the envelope—the format of the recipient address and how that address rotates. For large-group messages, Keychat adopts exactly the same envelope as a Nostr direct message (NIP-17), blending the traffic so thoroughly that an outside observer cannot distinguish a Keychat message from a Nostr DM. Why does Keychat choose the Signal protocol over MLS for one-to-one chats? Because Signal’s ratchet advances more frequently than MLS’s, providing stronger post-compromise security. Could Keychat’s large groups interoperate with White Noise’s groups in the future? Quite possible—after all, the two are already 90 % identical. View quoted note →
