> That's my optimistic forecast for what happens after the current speculative bubble pops. We'll be left with e.g. universal sign-on via crypto wallet that's not owned by any corporation and can be used for cryptographic signature / voting / &c.

This seems entirely self-contradictory. How do you certify that a nominally anonymous cryptographic ID represents a particular individual for the purposes of signature/voting without some real-world (likely centralized!) entity establishing a connection between the two?

This seems like fundamentally the same problem that SSL certificates are trying to solve for website identity and I don't see how blockchain removes the need for a central authority somewhere if you want guarantees like "one person, one vote".

Why assume you need a pseudonymous persona to map onto a real world ID? Check out how DAO proposals work at e.g. https://gitcoin.co/grants/

There's a bunch of cool stuff if you Google "proof of {humanity,personhood}". Here's the wiki page: https://en.m.wikipedia.org/wiki/Proof_of_personhood

It's all pretty new and not proven long term, but it is an area of active research.
