IMHO the world is just barely entering a phase of much greater warfare and cyber attacks. You haven't seen nothing yet. I want several levels more security -- for my private keys, and also for the trust relationships. And I think we can do it.
I believe the NSA (or similar) can easily right now spy on anybody's SSL by just directing LetsEncrypt to print them a fraudulent certificate, directing Cloudfare to steal the traffic, and the only thing the target could potentially notice is that the bits in the certificate have changed (but it validates perfectly)... routing the traffic back to the real TLS server with only a minor performance hiccup. That is because routing is not trustable, CAs are not trustable, DNS, etc.
So yes you could solve this with Tor and I2P at great performance cost. Or you could lookup a relay's current IP address in the Mainline DHT every hour (and they can jump to a new IP network every hour) and use that to connect to that relay under a TLS connection that is secured with the relay's nostr key. You bypass CAs, DNS, and even though routing can be fucked around with you can just hop somewhere else. And you maintain full performance. And you didn't have to build a new packet switched loran network.
Anyhow, this isn't nostr really I'm talking about anymore, it's Mosaic. It already does all this. Not quite ready to debut.
