Worldcoin (WLD) has emerged as one of the most talked-about blockchain projects in recent years, drawing global attention not only for its ambitious vision of universal digital identity and financial inclusion but also for its unique use of biometric technology. Backed by Sam Altman, CEO of OpenAI and co-creator of ChatGPT, Worldcoin aims to build a decentralized, privacy-preserving network that verifies human uniqueness on the internet—potentially laying the groundwork for future AI-driven economies and even universal basic income.
In this comprehensive guide, we’ll explore what Worldcoin is, how it works, the role of its WLD token, its real-world adoption, and the controversies surrounding it—giving you a clear, up-to-date understanding of this groundbreaking project.
What Is Worldcoin? The Vision Behind the Project
Worldcoin is an open-source protocol launched with a bold mission: to create a global financial and identity network owned collectively by all people. At its core, the project seeks to answer two critical questions in the digital age:
- How can we prove someone is a real human—not a bot?
- How can we fairly distribute economic value in an increasingly AI-dominated world?
To address these challenges, Worldcoin combines blockchain technology, biometric verification, and cryptoeconomic incentives into a unified system. It introduces three key components:
- World ID – A privacy-preserving digital identity that proves you’re a unique human.
- World App – A cryptocurrency wallet that stores your World ID and WLD tokens.
- WLD Token – The native cryptocurrency used for governance, payments, and rewards.
The ultimate goal? To build the world’s largest “proof-of-personhood” network—one that enables fair access to digital services, protects against AI-generated fraud, and supports inclusive economic systems.

How Does Worldcoin Work? Understanding the System
Worldcoin operates through a carefully designed ecosystem involving hardware, software, and decentralized infrastructure. Here's how it all comes together.
1. The Orb: Biometric Verification Device
At the heart of Worldcoin’s identity system is the Orb, a spherical hardware device that scans users’ irises using near-infrared imaging. This process creates a unique cryptographic hash called an IrisHash, which serves as proof of a person’s biological uniqueness.
Key facts about the Orb:
- It does not store raw iris images—only encrypted hashes.
- The scanning process takes less than 30 seconds.
- Each person can only register once; duplicate attempts are blocked.
The Orb ensures that each World ID is tied to a real, unique individual—making mass account creation by bots nearly impossible.
2. Zero-Knowledge Proofs and Privacy Protection
After verification, users receive a World ID stored in the World App. This ID uses zero-knowledge proof (ZKP) technology, allowing individuals to verify their humanity without revealing personal data.
For example:
- You can prove you’re over 18 without disclosing your birthdate.
- You can confirm you haven’t claimed airdrops multiple times without exposing your identity.
This balance between verification and privacy is central to Worldcoin’s long-term credibility.
3. Integration with Blockchain Infrastructure
Worldcoin runs as a Layer 2 solution on Optimism, leveraging Ethereum’s security while enabling low-cost, high-speed transactions. The WLD token is an ERC-20 token on Ethereum, though most transactions occur on Optimism for scalability.
This setup allows millions of users—especially in emerging markets—to interact with Web3 applications affordably and efficiently.
WLD Token: Purpose, Distribution, and Economics
The WLD token is more than just a cryptocurrency—it's a foundational element of the Worldcoin ecosystem.
Token Overview
- Total Supply: 10 billion WLD
- Circulating Supply: ~1.51 billion (as of mid-2025)
- Blockchain: Ethereum (via Optimism L2)
- Token Standard: ERC-20
- Launch Date: July 24, 2023
Allocation Breakdown
According to the latest whitepaper:
- 75% to Community: Distributed via airdrops to verified users and ecosystem incentives.
- 9.8% to Developers: Allocated to Tools for Humanity (TFH) and early contributors.
- 13.5% to TFH Investors: Rewards early financial backers.
- 1.7% Reserved: Held by TFH for future development.
Notably, 80% of the total supply is reserved for community distribution over time, with decreasing rewards for early adopters to encourage broad participation.
Funding and Market Performance
In May 2025, the Worldcoin Foundation raised $135 million from top investors including Andreessen Horowitz (a16z) and Bain Capital Crypto. The funding was structured as a direct purchase of liquid WLD tokens at market price, signaling strong institutional confidence.
Market response was immediate:
- Trading volume surged by 87%, exceeding $500 million.
- Derivatives volume jumped 112%, reaching $879 million.
- WLD price rose over 26% in one day, peaking at $1.54.
As of mid-2025, WLD ranks among the top 60 cryptocurrencies by market cap, hovering around $1.5 billion.
Real-World Adoption: User Growth and Global Reach
Despite controversy, Worldcoin has achieved significant real-world traction.
Key Metrics (as of 2025)
- Over 13 million iris scans completed globally
- More than 1.6 million active unique users
- Available in over 894 Orb locations across 35+ countries
- Peak daily active users: 12,000+
