Worldcoin, the crypto project founded by ChatGPT creator Sam Altman two years ago, recently made headlines with its $115 million Series C funding round. This "veteran project" has regained significant attention—partly fueled by ChatGPT's global AI boom.
But what exactly is Worldcoin? What problems does it aim to solve? How does its Orb technology work? Below, we break down everything you need to know about this ambitious project.
1. What Is Worldcoin?
Worldcoin is a decentralized world ID initiative that uses biometric authentication (iris scanning) to create unique digital identities. These identities, called World IDs, leverage zero-knowledge (ZK) proofs to anonymously verify users as human—preventing Sybil attacks (e.g., duplicate accounts).
Key features:
- Tokenomics: The Worldcoin Token (WLD) has a max supply of 10 billion: 8 billion for free global distribution, 2 billion reserved for investors/foundations.
- Adoption: Over 1.7 million users have registered via World App (currently in beta).
Recent Updates (May 2023):
- May 25: Closed $115M Series C led by Blockchain Capital.
- May 11: Migrated from Polygon to Optimism mainnet, launching Optimistic World NFTs.
- May 8: Launched World App, a gas-free wallet supporting USDC/Uniswap/MoonPay in 80+ countries.
2. Worldcoin’s Mission
Per McKinsey, 4.4 billion people lack legal/digital identities. Worldcoin envisions a universal digital identity and currency system by scanning irises globally.
How It Achieves Fair Distribution:
- Airdrops: Free WLD tokens distributed via blockchain—no financial/identity barriers.
- Biometric Proof: Orb devices collect iris data to prevent Sybil attacks.

3. Orb Technology Explained
The Orb is a custom biometric device that uses iris recognition to verify uniqueness while prioritizing privacy.
Technical Highlights:
- Hardware: Sealed optical system, 2D gimbal, liquid lens for autofocus, and NIR-optimized sensors.
- Privacy: Images are processed locally and deleted; only an Iris Code is stored.
- Decentralization: Orb designs and partial code are open-source.
Node Operators: Incentivized to onboard users (rewards decrease over time).
4. How Worldcoin Works
Key Components:
- World ID: Anonymous, ZK-proof-based identity protocol.
- WLD Token: ERC-20 token on Optimism (Layer 2).
- World App: Self-custody wallet for payments/transfers.
5. How to Use Worldcoin (Step-by-Step)
Download World App: Set up an account + connect a wallet.
- Note: Currently available in 80+ countries (excludes mainland China).
Verify via Orb: Scan your iris to activate World ID and claim WLD tokens.
- Upcoming: WLD tokens will be usable for payments/governance.
⚠️ Warning: Scams selling "pre-verified" accounts may steal assets.
FAQs
Q1: Is Worldcoin available worldwide?
A: No—the app excludes certain regions (e.g., mainland China). Orb access is also limited.
Q2: How does Orb protect privacy?
A: Iris images are deleted after processing; only a unique code is stored.
Q3: When will WLD tokens launch?
A: Expected within weeks (as of May 2023).
Final Thoughts
Worldcoin merges cutting-edge tech with lofty ideals, but faces hurdles like regulatory scrutiny over biometric data. Its upcoming blockchain protocol could redefine digital identity—stay tuned!
