> 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".
