About
World, formerly known as Worldcoin, is a human-first identity and financial infrastructure project built for the age of AI. At its core is World ID, a universal proof-of-personhood credential generated through biometric iris verification via a physical device called the Orb. This enables anyone to cryptographically prove they are a unique, real human — without revealing personal data — solving the growing challenge of distinguishing humans from AI bots online. World App serves as the gateway to the ecosystem, offering globally inclusive financial tools including crypto wallets, payments, and access to the WLD token. World Chain is the underlying blockchain powering the network. Businesses and developers can integrate World ID to protect their platforms from bots and Sybil attacks, with existing integrations including Zoom, DocuSign, Browserbase, Okta, and Vercel. World's use cases span online dating verification, gaming anti-cheat, event ticketing (via Concert Kit), AI agent authentication, and decentralized governance. It is free to join, operates across 160+ countries, and is designed to be owned by the people who use it. The project was conceived so that every human benefits from the advancements of AI — making trustworthy digital identity a public good rather than a corporate product.
Key Features
- World ID — Proof of Personhood: A privacy-preserving digital credential that cryptographically proves a user is a unique, real human, verified via iris biometrics through the Orb device.
- World App — Universal Financial Access: A mobile app providing crypto wallets, payments, and access to global financial tools, available to anyone regardless of location or banking status.
- Business & Developer Integrations: World ID can be embedded into third-party platforms (Zoom, DocuSign, Vercel, Okta) to protect against bots, Sybil attacks, and AI impersonation.
- World Chain: A blockchain purpose-built for the World ecosystem, powering the WLD token and enabling decentralized human-first applications at global scale.
- Anti-Bot Use Cases: Purpose-built solutions for ticketing (Concert Kit), online dating, gaming, and AI agent authentication to ensure real human participation.
Use Cases
- Businesses integrating World ID to prevent bot signups, Sybil attacks, and AI impersonation on their platforms.
- Event organizers using Concert Kit to ensure tickets go to real fans rather than bots or scalpers.
- Online dating and gaming platforms verifying that users are genuine humans for safer, fairer experiences.
- Developers building AI agent workflows that require verified human oversight or authorization checkpoints.
- Individuals in underserved regions accessing global financial services and digital identity through World App.
Pros
- Free to Join: World ID verification and World App are free for individuals, making digital identity accessible to anyone globally regardless of economic status.
- Strong Privacy Preservation: Biometric data is processed locally and not stored centrally; users receive a zero-knowledge credential that proves humanity without revealing identity.
- Rapidly Growing Ecosystem: Major integrations with Zoom, DocuSign, Vercel, and Okta signal fast adoption, with millions of verified users across 160 countries.
- Broad Use Case Coverage: Addresses human verification across diverse domains — ticketing, gaming, dating, finance, AI agents — through a single universal identity layer.
Cons
- Physical Orb Verification Required: Obtaining a full World ID requires visiting a physical Orb device location, which may not be accessible to users in all regions or rural areas.
- WLD Token Geographic Restrictions: The Worldcoin (WLD) token is unavailable in New York and other restricted territories, limiting the financial benefits for some users.
- Biometric Data Privacy Concerns: Despite privacy-by-design claims, collecting iris data raises ongoing concerns among regulators and privacy advocates in multiple countries.
Frequently Asked Questions
What is World ID?
World ID is a privacy-preserving proof-of-personhood credential. After biometric iris verification via the Orb, users receive a cryptographic proof they can use to confirm their humanity online — without revealing any personal information.
How does Orb verification work?
The Orb is a physical device that scans a user's iris to generate a unique biometric hash. This hash is used to create the World ID credential. The raw biometric data is not stored; only the anonymous hash is used for verification.
Is World free to use?
Yes. Joining World, obtaining a World ID, and using World App are all free. WLD tokens may be distributed to verified users subject to geographic eligibility restrictions.
How can businesses integrate World ID?
Businesses and developers can use the World ID API and SDKs to add proof-of-human verification to their platforms. Existing integrations include Zoom, DocuSign, Vercel, Okta, Browserbase, and Exa.
What is the WLD token?
Worldcoin (WLD) is the native token of the World ecosystem. It serves as a universal currency and governance token, distributed to verified humans globally. Availability varies by country and is subject to regulatory restrictions.
