Interesting, I didn't know the space was thinking about proof-of-personhood. I've been entertaining the thought of something similar for years, to solve a lot of the problems we face.

A rough and very simplified version of the way I see it working is:

- When someone is born a private-key is created just like an SSN today and a fixed amount of coins are created on that "wallet"

- The amount would be based on the actual resources of the planet that are reasonable to spend during a life (inspired by Jacque Fresco and his Venus Project)

- The protocol would have a negative income tax set at a threshold where basic needs are met, so the broke would get UBI, the rich pay taxes

- Progressive tax to prevent ridiculous hoarding where the top 0.1% own almost everything (hoarding finite resources is a work around still to be solved)

- When someone dies that money could still be inherited, or when no next of kin and no will exists distributed to the poor as UBI

- Exploiting global resources would and should be costly

- There could still be corporations but they wouldn't create new coins

I see this solving a lot of problems:

- No more printing money to solve short term problems

- Everyone starts their adult life with some coin that could go towards education, drivers license etc

- No more tax havens since taxation is built into the protocol

- No more need for many of the government agencies we have today, reducing need for taxes

- Encourages a more circular economy with less waste

It's not perfect but I think it would be a nice compromise between the endless discussions of socialism vs capitalism.
