Introducing Keybase Chat
OP here! I had to trim the post down for brevity, but I thought the HN community in particular might be interested in the API side of things.<p>Undocumented in the post: you can invent channels for app-to-app communication from the JSON API. For example, it's possible with Keybase chat to have a program posting encrypted messages for another person or program, without cluttering up the <i>visual</i> chat interface.<p>Also - to test chat we've cut the invitation requirement. You should be able to try the app without anyone inviting you.
