Proof of person? um Interesting

Interesting concept, especially given that in real world social science, the individual is much more difficult to predict once singled out of the group. It could be technically more complex to implement but that to me seems more of a one-time hurdle. At the moment, simple steps like unique email/phone verification can be bypassed easily.

What about borrowing once more from the real world? Biometrics. I would rather give out my unique fingerprint for verification than a passport or ID card, for example.

Interesting idea, but i don't think it will work.

I'm not sure if i really understand this, but here is another interesting use of a blockchain involving one account per person.

Proof of stake and proof of work are based on decentralization, a hallmark of cryptocurrency, but both of these have the undesirable consequence of leading to possible centralization. With proof of work we see the development of large mining pools, eventually a possibility that a cooperation will result in 51%. Proof of stake seems to have an advantage of being greener, but it results in the rich getting richer and eventually, even if in hundreds of years, one party would attain 51%. Even in advance of that date, the currency could become unstable in anticipation of it. In current currency today, we see that 1% of Americans own >40% of the wealth. A consensus mechanism is necessary, but what cryptocurrency seems to want, with PoS and PoW being proxies, is 51% voting rights with proof of person. This would seem to solve several difficulties with cryptocurrency and create a very strong base. This does not have to be connected in any way to distribution, although it could. Proof of person/identity has been discussed at length in other threads:

If this could be done (which is technically difficult), wouldn't it solve problems of centralization while maintaining anonymity and other features, as well as being superior to PoS and PoW? What would be drawbacks of such a system?
