@trwnh for sure; lots of ways to deal with the phone number lookup thing, but "security is hard" in that context ๐
aside: I did a little work a couple of years ago on a thing I was calling "NNS" (the "Name Name System") around how we might use modern cryptographic assertions to step back from the relatively "centralized" mode of DNS (and by proxy, webfinger and atproto's approach), but then IPFS etc imploded and the funding/interest dried up. There are some similar efforts out there, too.
