Artificial intelligence is advancing at an unprecedented pace, bringing transformative benefits like automation and intelligent content generation. Yet, it also introduces risks—deepfakes, identity fraud, and bot-driven manipulation are growing concerns. In response, OpenAI CEO Sam Altman launched Worldcoin, a bold initiative that combines blockchain technology and biometric verification to establish digital personhood in the age of AI.
Worldcoin aims to create a globally inclusive financial ecosystem by offering a decentralized digital identity (World ID) and a cryptocurrency token—all while ensuring each user is a unique human being. This article explores how Worldcoin works, its underlying technology, privacy safeguards, and what the future may hold for this ambitious project.
What Is Worldcoin?
Worldcoin is a decentralized cryptocurrency and identity protocol co-founded by Sam Altman, Alex Blania, and Max Novendstern. It leverages blockchain and AI to build an open-source platform that grants individuals access to a borderless, equitable digital economy.
At its core, Worldcoin addresses two major challenges:
- Proving that users are real humans (not bots or AI-generated accounts)
- Distributing economic value fairly across the globe
The system revolves around three key components:
- World ID – A privacy-preserving digital identity verified through biometric scanning.
- Worldcoin Token (WLD) – A cryptocurrency distributed freely to verified users.
- World App – A mobile application enabling payments, transfers, and interactions with Web3 services.
Unlike traditional cryptocurrencies such as Bitcoin or Ethereum, which require investment or mining, Worldcoin offers an initial allocation of tokens at no cost—provided users complete identity verification via iris scanning.

How Does Worldcoin Work?
The cornerstone of Worldcoin’s innovation is the Orb, a spherical hardware device roughly the size of a bowling ball. Located in over 35 countries across Africa, Asia, Europe, and the Americas—including cities like New York and San Francisco—the Orb performs iris scans to confirm a user’s uniqueness.
Here’s how the process works:
- Users download the World App and create a crypto wallet.
- They visit a local Orb center for an in-person iris scan.
- The Orb captures the iris pattern and generates a unique cryptographic hash called an IrisHash.
- This IrisHash becomes part of the user’s World ID and is stored on a decentralized blockchain.
- Biometric data is anonymized and never stored in identifiable form.
Each person can only register once, preventing duplicate accounts and sybil attacks—common issues in digital systems vulnerable to bot infiltration.
Because irises are as unique as fingerprints, this method provides high-confidence human verification. The entire system operates without central control, aligning with blockchain principles of decentralization and user sovereignty.
Secure Multi-Party Computation (SMPC) and Data Privacy
On May 15, 2024, Worldcoin introduced a major upgrade: Secure Multi-Party Computation (SMPC)—a cutting-edge cryptographic protocol designed to enhance biometric data security.
Under the new SMPC system:
- Iris data is encrypted and split into multiple fragments.
- These fragments are distributed across separate, secure nodes.
- No single node can reconstruct the full biometric data.
- Full decryption requires cooperation from all parties involved.
This approach ensures that even if one storage location is compromised, attackers cannot access usable biometric information. Additionally, SMPC is believed to be resistant to future threats posed by quantum computing.
Importantly, Worldcoin announced that all legacy iris data collected under the previous system has been permanently deleted during migration to SMPC. The protocol is open-sourced on GitHub, encouraging broader adoption for secure identity solutions beyond Worldcoin itself.
The Three Steps to Join Worldcoin
Getting started with Worldcoin involves three straightforward stages:
1. Download the World App
The app serves as your gateway to digital identity and finance. It includes a built-in crypto wallet compatible with major blockchains like Bitcoin and Ethereum via WalletConnect. You can also link it to social platforms such as X (formerly Twitter) and Instagram for seamless authentication.
2. Sign Up for World ID
While you can use basic features of the app without verification, claiming free tokens requires identity confirmation. This means visiting an Orb center and completing the iris scan process.
3. Claim Your Free Tokens
Once verified, users receive:
- A share of Worldcoin (WLD) tokens, where available.
- Access to airdrops of other digital currencies like Bitcoin and Ethereum.
- Enhanced capabilities within Web3 applications requiring proof of personhood.
This model promotes financial inclusion by offering underbanked populations a direct entry point into the global digital economy.

Addressing User Privacy Concerns
Despite its innovative approach, Worldcoin has faced scrutiny over privacy implications. Critics worry about:
- Centralization of sensitive biometric data
- Potential black-market sales of iris scans
- Informed consent in low-digital-literacy regions
Worldcoin responds by emphasizing its privacy-by-design framework:
- Raw biometric data is deleted immediately after IrisHash generation.
- IrisHashes are not reversible into images.
- Data is encrypted using advanced protocols like SMPC.
- Users retain full control over their digital identity.
Regulators in several countries have launched investigations, particularly regarding data handling practices in vulnerable communities. However, Worldcoin continues refining its compliance strategies and transparency measures to build public trust.
The Future of Worldcoin
Worldcoin envisions a world where digital identity is both secure and universally accessible. By solving the “proof of personhood” problem, it lays the groundwork for fairer distribution mechanisms in:
- Universal Basic Income (UBI) experiments
- Anti-fraud systems in online voting
- Bot-resistant social media platforms
- Transparent aid distribution
Moreover, third-party organizations may eventually adopt Worldcoin’s verification infrastructure to prevent scams and strengthen cybersecurity across Web3 ecosystems.
As adoption grows, so does the potential for Worldcoin to redefine how we authenticate identity online—not through passwords or documents, but through something inherently unique: our biology.

Frequently Asked Questions (FAQ)
Q: Is Worldcoin legal in all countries?
A: No. While Worldcoin operates in over 35 countries, regulatory approval varies. Some nations have restricted or banned its use due to data privacy laws.
Q: Can I get Worldcoin without an iris scan?
A: Not currently. To receive tokens or a verified World ID, you must complete the Orb-based iris scan at an authorized location.
Q: How does Worldcoin prevent duplicate accounts?
A: The iris scan ensures each person registers only once. Since no two irises are alike, this method effectively blocks bots and fake identities.
Q: Is my biometric data safe with Worldcoin?
A: Yes. Raw iris images are deleted after processing. Only encrypted IrisHashes are stored, and with SMPC, they remain fragmented and indecipherable without full network cooperation.
Q: What can I do with World ID besides claim tokens?
A: World ID can be used to verify humanity across apps—preventing bots in online communities, securing voting systems, or accessing exclusive digital services.
Q: Is Worldcoin similar to Bitcoin?
A: While both are blockchain-based, they serve different purposes. Bitcoin is primarily a decentralized currency; Worldcoin focuses on proving unique human identity and distributing tokens fairly.
