Some people believe that government issued ID in conjunction with a government that implemented a UBI scheme would indeed improve poverty. Andrew Yang wrote a reasonable book about the idea.
sybil-proofing in blockchain systems opens the possibility for any person or community to take a shot at implementing UBI. Could someone succeed in creating a token that retains some level of value long term and also consistently tops up at some rate in everyone's wallet? Beats me. But sybil-proofing is absolutely blocking issue on that front.
I am serious that it is straightforward to create a token where everyone on earth gets X/day in a sybil proof system.
Making this token retain some sort of value is of course an entirely different problem, and I don't have strong opinions on whether someone might pull it off.
This is their mission, and the rest of the website focuses on ID and such services. Not one mention of poverty alleviation.
