As I understand it, the distribution mechanism of Worldcoin is not part of the protocol. The protocol does not know anything about eyes. So the distribution seems completely centralized. A central authority distributes the coins however they wish. Today they might use a process involving eye scans. Or maybe not. There is no way to check. Tomorrow they might change their approach however they like. And we would have n…

Correct.

No you can't. The whole point is to every everybody have only 1 entry / key. The concept is simple: give everybody an equal amount of coins. You need a unique identifier / derivative of it

How would you mass-generate unique identifiers?

I like the idea of a unique identity per person but I'm unsure about security: - Iris scans have false positives at scale - You can have eye surgery changing your iris - Cheap scanners can be fooled by photos, so you'd need to require live-tissue scanners which are really expensive

The single biometric identity per person is a terrible idea because it cannot be discarded once compromised.

Presumably the orbs produce a verifiable type of hash. E.g. whatever output it has is also encrypted with their private key + some salt and you can always check if what a user provides has that.

It can be done in following way. Orb can have a baked-in private key (on hardware level). Public keys are stored in the blockchain. Each hash is signed by the private key stored in the orb.

That implies a centralized signing authority though. We could do all of that without the retina scanning using normal old KYC

RIP Sam Altman's reputation

Genuine question: what is Sam Altman's reputation based on? I'm aware that Paul Graham had a serious mancrush on him, and that he somehow managed to turn a failed startup into a $40M acquihire, which is nothing to scoff at -- but is his success mostly based on his genius of selling himself and whatever he's involved in, or has he actually said or done anything that shows some deeper form of insight or ability?

selling garbage for $40M and charming an upcomimg billionaire requires insight and ability.

Worldcoin issues tokens to people for scanning their retinas. Their magical orb device sends a biometric hash to their network. Here's my take on it: You can possibly replace their biometric device with a random hash generator. * If it works, it means the currency is not fairly distributed, but anyone sending valid hashes to their network is issued tokens, irrespective of whether the eyeballs described by those hashe…

While I don't care about Worldcoin (I think it will fail, because they are solving the problem that does not exist), this post is false in multiple ways. First, retina scanning output hash is deterministic - it is supposed to generate the same result for the same eyeball. So it can't be replaced with random number generation. Second, network does not interpret hashes, except for making sure that single hash is awarde…

I don't see how the deterministic nature of retinal scanning hashes means they couldn't be forged randomly. If there's secret sauce or a secret key in the algorithm that generates the hash then it's not an open platform. And given the stakes, it's only a matter of time until that gets cracked.
