Like any other non-coin crypto tech, Worldcoin doesn't do what it set out to do because it doesn't solve the oracle problem. If you trust their orb, it generates a wallet for you - but anyone, human or otherwise - can use that wallet. There's a black market in China for these identities already [1] and of course the response from Worldcoin was there's nothing they can do - because there's nothing they can do. So this…
That was never the goal.
> There's a black market in China for these identities already
It is built such that eventually, Worldcoin identities can be trivially reclaimed by the iris owner, so the market for these identities will drop to zero once people realize they can just sell their same Worldcoin cred over and over again and some sucker is going to buy it.
Their only goal here is to create an identity registration system where..
1. people don't need money to register
2. people don't need to have special friends to register
This is a sybil resistance mechanism, and no other system today does this. Also, the registration is basically fully anonymous. There is no way for anyone to enumerate everyone who has registered, and there is no way to link a registrant with the wallet activity of a credential holder. Say what you will, but IMO these are some pretty useful mechanics, and there are quite a few applications of this technology that can't be done without something like this.
