Worldcoin iris biometrics

Worldcoin is a self-described 'digital identity and financial network' that uses a 'chrome orb' to scan the irises and faces of people agreeing to sign up for a share of its new WLD currency. 

Worldcoin was started in 2019 by Sam Altman and Alex Blania under the auspices of technology company Tools for Humanity (TFH). TFH claims it was established to 'accelerate the transition towards a more just economic system.'

The WLD currency started trading on July 24, 2023 under the auspices of the Worldcoin Foundation, a Cayman Islands 'exempted limited guarantee foundation company'. 

The currency trades in multiple jurisdictions - except the US, in which the laws are 'unclear', Worldcoin claims.
