Introduction
WorldCoin’s proof-of-personhood (PoP) system, known as World ID, combines blockchain, AI, and custom hardware—a biometric "orb" that scans users’ irises—to verify unique human identity. Developed by Tools for Humanity (co-founded by OpenAI CEO Sam Altman), the project aims to create a decentralized, universal identity network accessible to all, regardless of geographic or economic status.
Key Technologies Behind World ID
- Biometric Orb: Scans iris patterns to generate unique, irreversible cryptographic hashes.
- Blockchain: Built on Ethereum using Semaphore protocol for zero-knowledge proofs.
- AI Integration: Ensures scans belong to real humans (not bots or duplicates).

What Is Proof of Personhood?
PoP systems verify uniqueness and humanity, addressing gaps in decentralized autonomous organizations (DAOs) and token-based voting. World ID’s goals:
- Prevent Sybil attacks (fake identities).
- Enable universal basic income (UBI) via WorldCoin tokens (25 tokens ≈ $60 per scan).
How WorldCoin Works
- User Setup: Download the World App (a crypto wallet) to generate cryptographic keys.
- Orb Verification: Visit an orb to scan your iris; data is hashed and stored on-chain.
- Uniqueness Check: Ethereum blockchain validates the scan via zero-knowledge proofs.
Technical Safeguards:
- Iris hashes cannot be reverse-engineered.
- Centralized database (for now) with plans for full decentralization.
Potential Applications
- UBI Distribution: WorldCoin as a global cryptocurrency for basic income.
- Enterprise/Government Use: Authentication for services, voting systems, and financial inclusion.
- Cybersecurity: Influences passkeys and decentralized identity solutions.
Challenges and Criticisms
- Privacy Concerns: Despite safeguards, distrust persists around mass biometric data collection.
- Scalability: High Ethereum gas fees ($100 per scan) initially hindered adoption.
- Viability: Competing with established Web2.0 IAM providers like Auth0.

FAQs
1. How does WorldCoin ensure privacy?
World ID uses zero-knowledge proofs to verify uniqueness without revealing raw biometric data.
2. Can governments misuse World ID?
The system is designed to prevent surveillance, but critics warn of potential abuse if centralized controls weaken.
3. What’s the incentive to join?
Users receive 25 WorldCoin tokens (≈$60) and access to a universal identity framework.
4. Is WorldCoin decentralized?
Currently hybrid (centralized database), with plans to transition to full decentralization.
Conclusion
WorldCoin’s ambitious vision—while controversial—could spur innovations in decentralized identity and AI-resistant authentication. Whether it achieves global adoption or serves as a cautionary tale, its impact on cybersecurity and financial systems will be significant.
