What is Worldcoin?
Worldcoin is a unique project utilizing the Proof of Personhood mechanism to verify users’ identities through “iris scanning” using an Orb. The goal of Worldcoin is to create a global identification and financial system that facilitates easy access to cryptocurrency for users through “iris scanning” and rewards them with WLD tokens.
The idea behind Worldcoin originates from its two founders, Sam Altman (CEO of OpenAI) and Alex Blania, aiming to create a digital identity protocol to support distinguishing between real humans and artificial intelligence.
To achieve this, the project develops the Orb to scan users’ irises and provide each user with a unique digital identity “passport” called World ID.
How Worldcoin Works
To verify identity on Worldcoin, users need to create a private key and public key through the World App. Then, they visit a point with an installed Orb to scan their iris. If the process is successful, users will be confirmed as real humans by the protocol and receive a World ID, similar to a global digital passport.
The process of using the Orb to verify identity goes as follows:
- The Orb scans and captures the user’s iris.
- The Orb’s captured iris image is converted into a hash function and sent to the Worldcoin server to check if the user has registered before.
- If the user hasn’t registered, the hash function is added to the Worldcoin database and blockchain.
- Users receive free WLD tokens along with their World ID and access to the Worldcoin World App.

World ID
World ID is a decentralized identification solution designed to protect privacy, utilizing the Proof of Personhood mechanism. This mechanism allows each user to prove they are a “real human” rather than a “bot.” It’s implemented to prevent users from abusing the benefits provided by Worldcoin and to guard against Sybil Attacks.
World App
Before using the World App, users need to verify their identity through World ID after downloading the app on iOS and Android. The World App functions as a cryptocurrency wallet but also offers additional features:
- Users can receive, send, and trade tokens through the World App. Additionally, they can easily onboard and offboard funds through integrated services like Moonpay and Ramp.
- Apart from basic wallet functions, the World App provides “Learn to Earn” courses to help new users understand cryptocurrency better. Users who haven’t verified with World ID can still access learning materials, but rewards for “Earn” are only for those who have verified their identity with World ID.
- Users who have verified their identity with World ID in eligible countries can receive Worldcoin Grants monthly. The World App notifies users of new Grants, and they can request to receive them in WLD tokens using their verified World ID.
Key Features of Worldcoin
“The Orb” is a solution that Worldcoin employs to address various issues through biometric technology while safeguarding users’ privacy using zero-knowledge proof technology.
Participating in the financial economy can entail many identity verification-related risks. By using Orb’s iris scanning technology, Worldcoin hopes to address several issues:
- Uniqueness: The human iris is unique and cannot be copied, and using iris images helps users avoid data errors.
- Fraud resistance: The iris cannot be copied, helping prevent fraud.
- Practicality: Rapid development in imaging technology and easy accessibility.
If the iris scanning process from users goes well, the information comparison will create a narrow peak at 0, meaning user identification will be accurate and fast. However, there are still many sources of error, leading to identification not meeting requirements and increasing error rates during the comparison process.
