Worldcoin consists of a privacy-preserving digital identity network (World ID) built on proof of personhood and, where laws allow, a digital currency (WLD). Every human is eligible for a share of WLD simply for being human. World ID and WLD are currently complemented by World App, the first frontend to World ID and the Worldcoin Protocol, developed by the contributor team at Tools for Humanity (TFH).

“Proof of personhood” is one of the core ideas behind Worldcoin, and refers to establishing an individual is both human and unique. Once established, it gives the individual the ability to assert they are a real person and different from another real person, without having to reveal their real-world identity.

World ID is privacy preserving proof of personhood. It enables users to verify their humanness online while maintaining their privacy through zero-knowledge proofs, via a custom biometric device called the Orb. The Orb has been designed based on the realization that custom biometric hardware might be the only long term viable solution to issue AI-safe proof of personhood verifications. World IDs are issued on the Worldcoin protocol, which allows individuals to prove that they are human to any verifier (including web2 applications) while maintaining their privacy through zero-knowledge proofs. In the future, it should be possible to issue other credentials on the protocol as well.

World ID aspires to be personbound, meaning a World ID should only be used by the individual it was issued to. It should be very difficult to use by a fraudulent actor who stole or acquired World ID credentials. Further, it should always be possible for an individual to regain possession of a lost or stolen World ID.

Availability: Worldcoin (WLD) tokens are not available to people or companies who are residents of, or are located, incorporated or have a registered agent in, the United States or certain other restricted territories. However, World ID and TFH’s World App remain available in the United States. More details can be found in the Terms of Use, including additional restrictions on Eligibility (see Section 1.2).

Safety reminder: Free WLD tokens will only be claimable via World App – there is no airdrop of WLD outside the World App. There is no “ICO” of WLD. Watch out for fake apps and fake WLD tokens! The WLD token is only deployed on Ethereum and Optimism at the above addresses.

Important User Information: Crypto products can be highly risky and their regulatory treatment is unsettled in many jurisdictions. There may be no regulatory recourse for any loss from transactions in WLD. Any value ascribed to WLD may change quickly and may be lost in its entirety.
