The Black Market and the Importance of Zero Knowledge Proofs
There was this black market that popped up where people were selling world coin credentials. Users in countries where world coin is not active can't participate, which was mostly China. However, what you as a user will be able to do is you will just be able to recover your world coin by showing up on an orb again. You don't need Iris verification for that step anymore.
