What is Worldcoin Project?

Worldcoin, founded in 2021 by Sam Altman, CEO of OpenAI, will rely on biometric information that is difficult to fake and immutable to verify users through eye scans and generate a unique digital identity. Wordcoin prevents scenarios where one person has several accounts by allowing users to demonstrate their human identity while maintaining anonymity.

Because Worldcoin is a protocol focused on personal identification, the project has utilized a Proof of Personhood technique to validate a user’s identity via a “retina scan” using an Orb (labeled retina).


What is Worldcoin trying to solve?

According to an analysis by the McKinsey Global Institute, there are now more than 4.4 billion people who do not have a legitimate identity or are unable to verify their identity digitally. To solve this problem, Worldcoin came up with “Orb”.

Orb is a biometric device with a built-in scanner and external camera. If they are real people, they will be given an ID after a retina scan and let the AI analyze their data.

With a Proof of Personhood system that allows each user to prove that they are a “real person”, Worldcoin provides a decentralized identity and privacy protection solution while ensuring security.

Worldcoin takes the objective of universalizing cryptography to the world by placing Orbs in various countries and encouraging people to scan their “retina” for identification. However, because of the concerns surrounding the Proof of Personhood method and Orbs, we need additional time to verify the possibility of this goal.
