Sam Altman, co-founder of OpenAI, has launched a new product under his cryptocurrency initiative WorldCoin. Named World App, this consumer-focused application serves a dual purpose: it functions as a cryptocurrency wallet and aims to become a digital identity verification tool, often referred to as an "identity passport" for the age of artificial intelligence.
Built on the Ethereum sidechain Polygon, World App is designed for global accessibility, allowing anyone to download and use it at any time. In an era where large language models (LLM) and AI chatbots like ChatGPT are blurring the lines between humans and machines, Altman believes blockchain technology can play a crucial role in distinguishing real people from artificial intelligence.
The Three-Part Mission of WorldCoin
The WorldCoin project is structured around three core components:
- World ID: A unique identity verification system.
- A Associated Cryptocurrency: A dedicated digital currency.
- World App: An application that brings the ecosystem to users.
A key feature of the World ID system is its use of iris-scanning technology for identity proof. This biometric verification is intended to ensure that each user is a unique human individual, creating a reliable method for authentication in digital spaces.
From Basic Income to Identity Proof
Initially conceived three years ago by Sam Altman and Alex Blania, the project's original vision was to use cryptocurrency as an infrastructure for universal basic income. However, the initiative faced early challenges, including skepticism from media outlets and concerns within the crypto industry regarding its model of offering cryptocurrency in exchange for iris scans.
Critics raised questions about data privacy and the risks of collecting sensitive biometric information. In response to these concerns and the rapidly evolving AI landscape, the project was repositioned in early 2023. The new focus shifted squarely toward "proof of personhood," with the World ID protocol being marketed to developers as a tool for human verification in applications.
This system is designed to confirm that a user is a unique human and not an AI program or a virtual identity. For transactions, the app utilizes zero-knowledge proofs (ZKPs), a cryptographic method that allows a user to validate information without revealing the underlying data itself.
World App: A Simplified Crypto Experience
For users without a World ID, the app operates as a streamlined cryptocurrency wallet. It allows people to buy, sell, and store digital assets like Bitcoin, Ethereum, and select stablecoins, such as DAI. The development team intentionally limited its feature set to avoid overwhelming new users, opting for a minimalist design that prioritizes ease of use.
The app leverages the Polygon network, which offers lower transaction fees compared to the main Ethereum blockchain. This makes it a cost-effective option for users.
For those who have undergone the iris-scanning verification and possess a World ID, the app transforms into a powerful digital passport. It grants access to services and applications reserved for verified humans, providing a new layer of trust online. The app also emphasizes user privacy and self-custody of crypto assets, putting users in control of their passwords and data.

Since its beta release, the application has seen significant uptake. Reports indicate that over 150,000 users participated in the testing phase, with more than 50,000 active monthly users. On its peak day in beta, the app processed approximately 60,000 transactions and verified 25,000 identities from users around the world.
The Road Ahead and Enterprise Potential
Sam Altman has argued that the advancement of AI is creating a growing need for systems that can prove a user is human. He also highlights the potential for new models of wealth distribution and global governance. For his vision to be fully realized, however, mass adoption—exceeding one billion users—is necessary. This includes overcoming skepticism from those wary of biometrics and cryptocurrency.
While the full potential of World ID is still being explored, the company behind it, Tools for Humanity, is already providing tangible benefits. World ID holders, for instance, can make free transactions within the World App.
Looking forward, the most promising strategy for WorldCoin may lie in enterprise adoption. The company is actively promoting its identity verification technology to other businesses and applications, a move that could prove to be highly lucrative and cement its role in the future of online identity.
Frequently Asked Questions
What is the primary purpose of World App?
World App serves two main functions. It is a user-friendly cryptocurrency wallet for managing digital assets like Bitcoin and Ethereum. More uniquely, it acts as a gateway to World ID, a digital identity system that uses biometrics to verify a user is a human and not an AI.
How does World ID use iris scanning?
The World ID system uses an iris scan to create a unique identifier for each user. This biometric data is used to generate a zero-knowledge proof, which allows apps to confirm you are a real person without ever storing or sharing your actual iris data, enhancing privacy and security.
Is World App available to everyone?
Yes, anyone can download and use World App. However, access to features that require proof of humanity is restricted to users who have completed the World ID verification process through the iris-scanning orb.
What cryptocurrencies does World App support?
The wallet initially supports major digital assets including Bitcoin, Ethereum, and stablecoins like DAI. It is built on the Polygon network to ensure fast and low-cost transactions, with plans to add more tokens in the future.
Why is there a need for proof of personhood in the AI era?
As AI becomes more sophisticated, it becomes harder to distinguish between human and machine-generated activity online. Systems like World ID provide a way to ensure that online services, governance, and economic systems can function with the certainty that they are interacting with unique human individuals.
