 Gossip is a desktop client for nostr.
 
-Nostr is a social media protocol and ecosystem, kind of like Twitter, Mastodon, Gab, Post, Gettr, Farcaster, Truth social, BlueSky, Locals, Minds, Spoutable, etc, etc.... except that you control your own account and nobody can silence you so long as some relay operator somewhere allows you to post.

People are finding many additional uses for nostr that go far beyond just chatting, but this client is focused on chatting.
 
 Nostr stands for "Notes and Other Stuff Transmitted by Relays."

+- **High-enough performance**: the network speed should be your limiting factor on performance, not the UI or any other part of the code. It doesn't matter too much how fast the code runs as long as it is always faster than the network, and I think that's definitely true for gossip. However due to our use of an immediate-mode renderer which computes and redraws frequently, we will continue to try to minimize the CPU impact of that hot loop.
 - **High user control**: the plan is for the user to be in control of quite a lot of settings regarding which posts they see, which relays to talk to, and when to fetch from them, but with some sane defaults so you don't have to change anything.
+- **Privacy Options**: in case someone wishes to remain secret they should use Gossip over Tor - I recommend using QubesOS do to this. But you could use Whonix or even Tails. Don't just do it on your normal OS which won't do Tor completely. Gossip will provide options to support privacy usage such as not loading avatars, having multiple identities, etc.
+- **Key Security**: private keys need to be handled as securely as possible. We store the key encrypted under a passphrase on disk, and we zero out any memory that has seen either the key or the password that decrypts it. We also keep the decrypted key in just one place, the Signer, which doesn't provide access to the key directly. Eventually we will look to add hardware token support, probably first using programmable [Solo keys](https://solokeys.com/) because I have a half dozen of those.
