The Worldcoin project, which is set to launch soon, requires individuals to prove their uniqueness through an iris scan by one of Worldcoin's orbs. Over 1.7 million people have already signed up, with the majority of them in the Global South. However, scammers are finding ways to cheat the system, with people in China reportedly purchasing iris scans taken in Cambodia and Africa for as little as $30. Worldcoin has acknowledged these incidents, stating that the problem was confined to a few hundred instances, and has taken several steps to contain the issue. Despite these precautions, the project admits that innovative ideas in mechanism design and the attribution of social relationships will be necessary to address challenges such as collusion or attempts to bypass the one-person-one-proof principle. The token is set to launch in the first half of this year, and the organization is currently valued at $3 billion after reportedly raising $100 million from Khosla Ventures and a16z in March 2022.
