Worldcoin is one of the most ambitious and controversial projects at the intersection of cryptocurrency, digital identity, and artificial intelligence. With growing concerns about online impersonation, bot-driven fraud, and AI-generated content, the need for reliable human verification has never been more urgent. Worldcoin aims to solve this with a bold solution: using biometric iris scans to create a privacy-preserving digital identity known as World ID, while also distributing a cryptocurrency token, WLD, to verified users.
But how does it work? Who’s behind it? And what are the real risks and rewards? Let’s explore the technology, vision, and challenges behind Worldcoin.
The Digital Identity Crisis in the Age of AI
As AI becomes more advanced, distinguishing real humans from bots online is increasingly difficult. Deepfakes, automated accounts, and AI agents can mimic human behavior with alarming accuracy—threatening everything from online voting to social media integrity. Traditional identity systems, like government IDs or social logins, are often centralized, exclusionary, or vulnerable to fraud.
This is where Worldcoin steps in. It proposes a decentralized, global solution: a cryptographic proof-of-humanity system that verifies you’re a real person—without exposing your personal data.

Who Founded Worldcoin?
Worldcoin was co-founded in 2019 by Sam Altman (CEO of OpenAI), Alex Blania, and Max Novendstern under the parent company Tools for Humanity. Sam Altman’s involvement has drawn significant attention, given his influence in both AI and tech innovation. The team’s mission is simple but profound: build a system that allows anyone on Earth to prove they are a unique human being—especially critical in an era where AI can replicate human activity at scale.
Their vision extends beyond identity; they aim to foster global economic inclusion by giving people access to cryptocurrency and financial tools, regardless of location or income level.
How Does Worldcoin Work?
At the heart of Worldcoin is the Orb, a futuristic, bowling-ball-sized device equipped with an iris-scanning camera. Here’s how the process works:
- Iris Scan: Users look into the Orb, which captures a high-resolution image of their iris—the colored ring around the pupil.
- IrisCode Generation: The scan generates a unique digital identifier called an IrisCode, based on the intricate patterns in the eye.
- Privacy Protection: The raw iris image is deleted immediately. The IrisCode is then converted into a cryptographic hash—a scrambled version of the data that cannot be reverse-engineered.
- Secure Storage: Using secure multi-party computation, the encrypted data is split into fragments stored across different servers. No single entity holds the full data.
- World ID Creation: Once verified as unique (i.e., not a duplicate), the user receives a World ID, a digital credential stored in the World App wallet.
- Token Reward: Users also receive a small amount of WLD tokens (typically around $42) as an incentive for joining.
The entire process is designed to verify humanity while minimizing privacy risks. Thanks to zero-knowledge proofs (ZKPs), users can prove they’re human without revealing any personal information. For example, when logging into a service using World ID, the platform only learns that the user is verified—not their name, location, or biometric data.
What Is the Purpose of Worldcoin?
Worldcoin aims to address two major global challenges:
1. Digital Identity Verification
In a world flooded with bots and AI-generated content, proving you’re human is becoming essential. World ID offers a decentralized way to do just that—enabling secure access to online services, voting systems, and community platforms without relying on centralized authorities.
2. Economic Inclusion
By rewarding users with free WLD tokens upon verification, Worldcoin lowers the barrier to entry for people in underserved regions. This aligns with broader visions of universal basic income (UBI) and financial empowerment through crypto.
Ultimately, Worldcoin envisions a future where every person has a secure digital identity and equal access to the global digital economy.
What Is Worldcoin Used For?
Worldcoin serves dual purposes:
🔐 Digital Identity Verification
- Prevent bot takeovers in online communities
- Enable fair participation in airdrops and token distributions
- Support secure digital voting systems
- Authenticate users in decentralized applications (dApps)
💸 Cryptocurrency Transactions
- WLD is an ERC-20 token on the Ethereum blockchain
- Can be traded on major exchanges
- Stored in Ethereum-compatible wallets like MetaMask or Ledger
- Used for payments, transfers, or participation in Web3 ecosystems
Developers are already integrating World ID into platforms requiring human verification, from fintech apps to DAO governance systems.

Key Concerns and Criticisms
Despite its innovative approach, Worldcoin faces significant scrutiny.
🛑 Privacy and Regulatory Challenges
- While Worldcoin claims biometric data is anonymized and fragmented, regulators—especially in the European Union—argue that IrisCodes could still qualify as personal data under GDPR.
- Critics question whether hashing truly eliminates re-identification risks.
- There are concerns about long-term data retention policies and lack of full deletion mechanisms.
🌍 Ethical and Surveillance Risks
- Iris patterns are permanent and unchangeable. If compromised, they cannot be reset like passwords.
- In authoritarian regimes, such biometric systems could be repurposed for mass surveillance or social control.
- Requiring biometric verification for online access may erode digital anonymity.
🤖 The AI Agent Paradox
Sam Altman leads both OpenAI (building advanced AI agents) and Worldcoin (verifying humans). This creates a paradox: if AI agents become widespread, users may delegate their World ID to bots—effectively allowing AI to act with human authority. This undermines the very idea of “proof of personhood.”
📉 Slow Adoption and Centralization Concerns
- As of 2025, only about 12 million people have been verified—far below the 50 million target.
- The Orb network is still limited geographically.
- Despite claims of decentralization, Tools for Humanity remains a centralized entity controlling key infrastructure.
How to Buy and Store Worldcoin (WLD)
Buying WLD
WLD tokens can be purchased on major cryptocurrency exchanges such as OKX, Coinbase, and Kraken. Simply create an account, complete KYC verification, deposit funds, and trade for WLD.

Storing WLD Safely
Since WLD is an Ethereum-based ERC-20 token, it can be stored in any wallet supporting this standard:
- Software Wallets: World App, MetaMask (convenient but less secure)
- Hardware Wallets: Ledger or Trezor (recommended for long-term storage)
Always back up your recovery phrase and never share your private keys.
Frequently Asked Questions
Why is Worldcoin not available in the USA?
Due to regulatory uncertainty around cryptocurrencies, U.S. residents cannot receive or trade WLD tokens. However, they can still undergo Orb verification for identity purposes.
What type of cryptocurrency is Worldcoin?
Worldcoin (WLD) is an ERC-20 token built on the Ethereum blockchain. It combines digital identity verification with monetary utility.
Is my iris data safe with Worldcoin?
Worldcoin uses cryptographic hashing and secure multi-party computation to protect biometric data. Raw images are deleted after scanning, but regulatory bodies continue to question whether IrisCodes fully comply with privacy laws like GDPR.
Can I delete my World ID?
Yes, users can delete their World ID through the World App. However, some critics argue that associated metadata may still persist in fragmented form across servers.
Does Worldcoin enable universal basic income?
While not a formal UBI program, Worldcoin’s model of distributing free tokens to verified individuals aligns with UBI principles by promoting financial inclusion.
Can bots use World ID?
Currently, only humans can obtain a World ID via Orb scanning. However, Worldcoin is exploring ways for users to delegate their identity to trusted AI agents—a move that raises ethical and security questions.
Final Thoughts
Worldcoin stands at the frontier of digital identity innovation. Its fusion of biometrics, cryptography, and cryptocurrency presents a compelling response to the challenges of AI-driven impersonation and financial exclusion. Yet, its path forward is fraught with ethical dilemmas, regulatory hurdles, and public trust issues.
For Worldcoin to succeed, it must balance technological ambition with robust privacy safeguards and transparent governance. Whether it becomes a cornerstone of Web3 identity or fades into controversy will depend on how it navigates these complex waters in the years ahead.
