Worldcoin is a bold and ambitious cryptocurrency initiative aiming to reshape how digital identities are verified and used in the global economy. At its core, it combines blockchain technology, biometrics, and a vision for financial inclusion to create a system where every person can prove their humanity online—safely and privately. This guide explores what Worldcoin is, how it works, its key components, benefits, concerns, and what lies ahead for this groundbreaking project.
Understanding Worldcoin: A New Digital Identity System
Worldcoin seeks to build a decentralized, global network of digital identities using iris scanning technology. The project’s primary goal is to establish a reliable method of verifying that users are real humans—not bots or AI-generated entities—while preserving privacy.
The foundation of this system is the Orb, a sleek, chrome-colored device about the size of a bowling ball. Located in over 30 cities worldwide, the Orb uses infrared cameras and AI-powered neural networks to scan a person’s iris—a biological feature unique to each individual. Within seconds, it generates a unique digital identifier called a World ID, which confirms the user’s “proof-of-personhood” without storing personally identifiable information.
Users who complete the verification process receive free Worldcoin (WLD) tokens, incentivizing participation while promoting widespread adoption.

Core Components of the Worldcoin Ecosystem
Worldcoin operates through four interconnected pillars:
1. World App
The World App serves as a self-custodial crypto wallet supporting WLD and other digital assets. It also functions as the interface for managing your World ID, enabling secure, private authentication across platforms.
2. World ID
This is the heart of the system—a privacy-preserving digital identity linked to your biometric data. Once verified via the Orb, your World ID allows you to prove you're human across various online services without revealing personal details.
3. Proof-of-Personhood
In an age where AI-generated content and fake accounts are rampant, distinguishing real people from digital fakes is critical. Worldcoin’s proof-of-personhood protocol ensures one person equals one identity, reducing fraud and enabling fairer access to digital resources.
4. Universal Basic Income (UBI) Vision
One of Worldcoin’s most forward-thinking goals is supporting a future AI-funded universal basic income. By distributing WLD tokens to verified individuals, the project lays the groundwork for a decentralized economic model where everyone can benefit from technological progress.
How to Use Worldcoin: Step-by-Step Guide
Getting started with Worldcoin is straightforward but involves physical verification.
Step 1: Download the World App
Available on Android and iOS, the app lets you begin setting up your digital identity and wallet.
Step 2: Register for a World ID
Locate an Orb near you using the app. Visit a trained operator who will guide you through the iris scan process. No personal documents are required—only your eyes.
Step 3: Claim Your WLD Tokens
After successful verification, you’ll receive free WLD tokens as part of the initial distribution. You may also be eligible for future airdrops of other cryptocurrencies.

Benefits of Worldcoin
Financial Inclusion for Underserved Populations
Millions lack access to formal identification or banking services. Worldcoin offers a way for these individuals to enter the digital economy, access financial tools, and participate in global transactions.
Enhanced Security Against AI Fraud
With rising concerns about deepfakes and bot networks, proving human identity online is more important than ever. Worldcoin’s biometric verification adds a robust layer of security.
Potential Pathway to Universal Basic Income
While still speculative, the idea of distributing WLD tokens as a form of UBI could help address economic inequality in a world increasingly shaped by automation and artificial intelligence.
Empowerment Through Decentralized Identity
By giving users control over their digital identities, Worldcoin reduces reliance on centralized institutions like governments or tech giants for identity verification.
The Technology Behind the Iris Scan
The Orb is no ordinary device—it represents years of R&D and cost millions to develop. Equipped with high-resolution infrared sensors and machine learning algorithms, it captures detailed patterns in the iris and converts them into a cryptographic hash stored on Ethereum’s Optimism Layer-2 network.
This ensures scalability and low transaction fees while maintaining security. The actual biometric data is deleted after hashing, leaving only an anonymized digital fingerprint.
Despite its sophistication, questions remain about hardware transparency, as not all components are open-source.
Privacy and Regulatory Challenges
While innovative, Worldcoin faces significant scrutiny over data handling and compliance.
Data Collection and User Consent
Initially, all scanned data was retained for research. Now, users can opt out—but concerns persist about how data is processed during registration and whether full deletion occurs.
Linking Identity to Wallets
Although World ID uses zero-knowledge proofs to protect privacy, linking it to exchange accounts requiring KYC procedures could expose user identities.
Centralization Concerns
Despite claims of decentralization, Tools for Humanity and the Worldcoin Foundation maintain control over smart contracts via multi-signature wallets—raising governance concerns.
Global Regulatory Scrutiny
Several countries—including Germany, France, Spain, and the UK—are investigating Worldcoin over compliance with data protection laws such as GDPR. In 2025, regulatory engagement continues with authorities like Germany’s BaFin monitoring financial aspects closely.
Worldcoin states it complies with privacy regulations in multiple jurisdictions, including Singapore’s PDPA, Japan’s APPI, and South Korea’s PIPA.
The WLD Token: Utility and Distribution
WLD is an ERC-20 token on Ethereum with a total supply cap of 10 billion. As of now, over 141 million WLD are in circulation.
Token Allocation
- 75% – Reserved for the Worldcoin community (incentives, ecosystem growth)
- 9.8% – Allocated to Tools for Humanity (TFH) team
- 13.5% – Designated for early investors
WLD functions as both a utility and governance token. Holders may influence protocol decisions through voting mechanisms enhanced by World ID—potentially enabling "one-person-one-vote" systems rather than "one-token-one-vote."
Storing Your WLD Safely
You can manage WLD through:
- The World App (mobile wallet)
- Popular software wallets like Trust Wallet, Atomic Wallet, and Ambire
- Hardware wallets such as Ledger or Trezor for maximum security
