Worldcoin (www.worldcoin.org) is an open-source protocol, supported by a global community of developers, individuals, economists and technologists committed to expanding participation in, and access to, the global economy. Its community is united around core beliefs in the inherent worth and equality of every individual, the right to personal privacy, and open and public collaboration. These beliefs are reflected in what the community is building: a public utility to connect everyone to the global economy.

The Worldcoin Foundation (www.worldcoin.foundation) is the protocol’s steward and will support and grow the Worldcoin community until it becomes self-sufficient.  Tools for Humanity (www.toolsforhumanity.com)  is a global hardware and software development company.  It helped launch Worldcoin and continues to provide support to the Foundation, in addition to operating the World App.

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 insecure environments. These systems are combined in a sleek industrial design with a simple, minimalist user interface.

For Worldcoin to launch successfully on a global scale, we need to both ensure fairness and build trust with our users. Therefore, it is essential to prevent fraud, protect privacy, and ensure availability.

Beyond regular company security the goal of security at Worldcoin is to deploy an edge device to unsecured environments. We consider a wide range of threats that span tampering with the device, spoofing the device as well as backend attacks. The cross-disciplinary nature of this team requires interfacing with various other teams across the company including Economics, AI, Backend and Orb Software.
