How do you propose one proves that they are (a unique) human?

  Web of trust? Absolute proof this way isn't possible, but you could render the cost of fraud very very high.

    > the cost of fraud very very high. Just high enough for lots of people and their friends to conspire against the rest of the network? I'm afraid web-of-trust alone is not enough to make a safe and useful cryptocoin. It would also require significant additional changes from current popular cryptocoin designs.

      >Just high enough for lots of people and their friends to conspire against the rest of the network? That depends upon what they conspire to do, surely? As far as I can see there are three attacks: * Creation of fictional people * Conspiracy to "unperson" a real person * Identity theft There are many defenses that could be put in place against all of these using a web of trust system. The PGP version is a little rudimentary to protect against them, but it's still a good foundation.
