WTF?
Yea why the fuck should I carve my identity into the blockchain forever??
Not yours, an identity which you can choose to use. And you can choose to have more than one, or none at all. Nothing to make any reference to you or anything specific to you unless you choose to do so. As stated above, it's a ridiculously powerful concept, I'm already calling it "blockchain backed information". It's an identity system, but one that you're in control of.
Ooh - that's cool. I haven't thought it through yet, but presumably there'd be non-centralized ways to control who uses which IDs - so "DPR" can't use "FBI" or vice versa?
Crytographically certified ways, of course. Although strings containing "DPR" and "FBI" would need to be created using VanityGen style tools. And, amusingly, alphabet agencies become relegated to any other rear-end in the showers, so to speak. They'll be using the information system, not their information system. Hah!
