Worldcoin developer CEO Alex Blania said in a group interview during this week's Korea Blockchain Week event that Worldcoin's current focus is on promoting Orbs globally. "I think fundamentally, unlike other networks we've seen over the last few decades [like PayPal, or even social networks like Facebook], they only become useful when they get to scale," says Mr. Blania. "So what we're looking at right now is global distribution and the number of users who are verified and using the service."
