- Your identity isn’t a username and doesn’t depend on a domain name or service provider. Instead, your username is a meaningless cryptographic hash that consists of random-looking numbers and letters. Your friends only need to know your hash to follow you, and you can keep it as public or private as you want.
Yeah, that sounds like a really positive user experience. Hard pass.
No one has or owns a "true name", collisions on names are expected and natural with a set of billions.
Crypto keys aren't supposed to collide, but on a set of billions this could happen. -- If it does have a contingency for replacing the PKI part of the identity. This also covers loss of key material, etc...
Identity is ephemeral and in flux.
An indexed web of trust, who knows who, etc might work.
