What is a circle relay? I just downloaded the app and have no idea what that is
Discussion
I just published a note. For the circle relay, you can use any public relay or a private relay. All messages within a circle will only be sent to the relay you’ve set for that circle.
Thank you, and yes, I saw the help text
we need square relays
Is there a table comparing whitenoise, 0xchat and keychat?
Not yet might be a good idea to put one together though.
To be honest, Whitenoise, Keychat, and 0xchat-lite share many similarities. Here are a few points focused on privacy and security for comparison. Also, both Whitenoise and 0xchat-lite are still in beta, and will continue to be improved over time—so this table is just a snapshot based on the current state. There may be some aspects missing.

Is the fact that White Noise and 0xchat are both on NIP-EE enough for interop? Or do the differences in receiver key rotation, media encryption, etc., make interop tricky, even though both are on NIP-EE?
Not enough — for now, only basic interoperability is possible. However, i believe whitenoise is expected to support key rotation and media encryption in the future as well; we’ve just taken those steps a bit earlier. 😂
