I do not understand how this is supposed to prevent sibyl attacks? How do they prevent fake virtual iris scanning devices from pretending that they scanned a person that doesn’t actually exist?

Each scanner is registered, authorised, tracked etc. Presumably with a private key but also I think they have the location, operator details and so on for every one.

Lots of good analysis here, with the main flaw (imho) coming in last*. The WC team may be book smart, but not experienced or wise, especially in building complex systems with high integrity and assurance. They cut too many corners, take too many intellectual shortcuts, assume away too many hard problems, minimize important constraints inherent in their chosen architecture, and clearly haven't really thought it all th…

I can’t imagine how naive you have to be to not see account selling as a massive problem. Especially when your plan is to first onboard users in poor countries. Why would these people do anything other than signup and immediately sell their accounts, for what may amount to a month or two of normal pay, just for waiting in line and getting scanned. I find it crazy that they claimed their system is Sybil resistant when…

If you are tech savvy you can sign up and convert the worldcoins to money yourself, via Kucoin or similar brokerages. Which is allowed and intended.

I am going to be downvoted to death, but it is clear from last year events that Sam Altman is truly that kind of "Blade Runner/Robocop(1)"-like antagonist character that has a narcissistic drive to destroy the world just so he can show everybody he is saving it. (1) Pick your 80's Sci-Fi movie dystopia that fits here.

It won't be clear till he turns the AIs against us ;) For now he's more Anakin Skywalker bit do not underestimate the power of the dark side.

>there is no “password reset” when it comes to iris data This is the most critical part, I think. If my Iris scan is leaked (which is not hard to do, from modified Orbs, similar to credit card skimmers, to mobsters scanning people's irises under threat of death), my identity will be stolen and I can't do anything about it. Do they have at least some sort of 2FA?

(Scanned yesterday). I don't think this is about identity. You don't have to give any when you scan - you can claim to Mickey Mouse for all they care. It's more a way to distribute shitcoins evenly.

Does anybody know if the actual iris information gets stored, or it’s just a hash of it ? Seems like there is no reason why the iris picture needs to be stored. But I’m not sure of the whole use case

It's a hash. But that doesn't eliminate the serious privacy issues with it.

Ok, Assuming the it’s a well known hash it seems a bit more secure.

Can’t do any searches on people based on the iris.
