The Orb is a biometric imaging device that privately and securely verifies an individual’s unique personhood. Here’s what that means.

Understanding the Orb and why Worldcoin uses biometrics

After years of R&D, we’re opening up the Orb to explain how it works and releasing corresponding hardware engineering files.

Explanatory Note: Tools for Humanity (TFH) led the initial research and development of the Worldcoin protocol, including the Orb. This year, prior to the launch of the decentralized network, the non-profit Worldcoin Foundation is taking over responsibility for facilitating participation in, and the continued development of, the protocol. The Worldcoin Foundation will continue to support and grow the Worldcoin community until it becomes self-sufficient, while TFH will support the Foundation, including by manufacturing and shipping Orbs. Currently in beta, Worldcoin expects to launch in the first half of 2023.
