This opportunity would be with Tools for Humanity.

About the Orb

Worldcoin's launch requires a "Proof-of-Personhood": a way to determine someone is human (not a bot) and hasn't already claimed their free share of Worldcoin. This is why we developed the Orb.

The Orb is an advanced biometric imaging device, custom-designed for Worldcoin's launch. Orbs are deployed to a global network of operators, who use the device to onboard new Worldcoin users. During this onboarding, the Orb generates an encoding of each user's iris and submits it to Worldcoin's backend. For more details on how the Orb is part of Worldcoin's privacy-preserving approach to Proof-of-Personhood, see the Worldcoin whitepaper.

The Orb solves a fierce combination of engineering and UX challenges, centered around image quality, security, and ease-of-use. Each device has an advanced iris imaging system, designed to work consistently across real-world lighting conditions. An additional suite of sensors feeds into an onboard fraud detection system, enabling use in unsecured environments. These systems are combined in a sleek industrial design with a simple, minimalist user interface.

About the Company

Worldcoin is a new, collectively owned global currency that will be distributed fairly to as many people as possible. Worldcoin will launch by giving a free share to everyone on Earth. We believe that this is an essential step to accelerate the transition towards a more inclusive global economy, providing new ways for everyone to share future prosperity. We hope you’ll join us on our ambitious journey.
