Sorry the term of art is really soulbound identity right now, I use POS but it's less common. Definitions vary but I say a useful system must allow people to endorse statements with evidence they are a) alive b) not able to be represented by more than one identity (id is linked to your entire soul, not a persona or facet of your being) c) a kind of socially recognized person (human in the expected case)

and then layer on citizenship on top if you want to use this for polling, voting, etc.

How would this work considering that the soul is an entirely fictional concept?

They use the term in crypto, it's just a metaphysical metaphor. It means non-transferrable.

Identity attributes on chain are "soulbound" to prevent people from exchanging them like other assets.

“Empirically unprovable” and “fictional” are not synonymous.

Do you believe you are capable of doing that yourself?

All you have to do is flip the tortoise back over.

> You’re in a desert walking along in the sand when all of the sudden you look down, and you see a tortoise, it’s crawling toward you. You reach down, you flip the tortoise over on its back. The tortoise lays on its back, its belly baking in the hot sun, beating its legs trying to turn itself over, but it can’t, not without your help. But you’re not helping. Why is that?

The point of the test is to see if the subject has had life experience enough that they could restrain their own empathy.

Wanting to flip the tortoise back over was why he failed the test.
