Here's my response which I hope you'll read. https://mirror.xyz/adamstallard.eth/Up0RpURQ24Ehh5Dw6vTDgMm67QAdoiCJEVt0576sTvU Feel free to chat or DM on discord or telegram. Maybe you could build some of this stuff with me; you're obviously still interested in it. @bitsikka.eth @ubipromoter @gloria

Mostly my response is to bring you up to speed on Aura, a new verification system for BrightID + a decentralized expert system for other domains. Also blind signatures in BrightID, and Unitap https://unitap.app which can help with the account renting problem by limiting the # of distinct apps / tokens a person can use.

> more ambitious proof-of-personhood project: Worldcoin @brightid is no less ambitious, just much less funded because we operate as a public good rather than a VC-backed company.

Let's say a real orb holder claims to help you get verified on Worldcoin, but instead they keep your new account for themselves. How do you recover? Does a new registration always invalidate an old one? If so, can someone who has your irises can continuously steal or invalidate your account?

If not, do we need to maintain an iris court to handle these disputes? How is it governed?

What prevents orb holders (or manufacturers) from creating massive sybil attacks? What does the graph of accountability look like among orb holders? If you create a decentralized system of accountability like this, you've created @brightid Aura (and probably don't need biometrics any more.)
