What Is Worldcoin?

In a world increasingly dominated by artificial intelligence (AI), the line between human and bot is blurring. This digital identity crisis poses significant threats to online systems, from social media to financial networks. Worldcoin, a project co-founded by OpenAI CEO Sam Altman, aims to solve this problem by creating a decentralized, privacy-preserving digital identity system and a global financial network. This essay explores what Worldcoin is, how it works, its history, its distinctive features, and its governance model.

Worldcoin is a project that seeks to build the world’s largest identity and financial network as a public utility. The core of the project consists of three main components: a global digital identity called World ID, a cryptocurrency token known as WLD, and a crypto wallet called the World App. The primary goal is to provide a “proof of humanity” solution in an age of AI, ensuring that a user is a unique, real person without revealing their personal data. By doing so, Worldcoin aims to democratize access to the global economy and potentially pave the way for a form of universal basic income (UBI) funded by AI-generated wealth.

The project addresses a critical challenge in Web3 and beyond: how to create a secure, verifiable, and inclusive digital identity that cannot be faked by bots. By linking a person’s unique biometric data to a World ID, the system ensures that each user is a one-of-a-kind individual. This allows for secure online interactions, equitable distribution of resources, and even democratic participation in online governance systems.

How It Works

The Worldcoin system revolves around the “Orb”, a specialized biometric imaging device. To obtain a World ID, a user must visit an Orb operator in person. The Orb scans the user’s iris, capturing the unique patterns of their eye. This iris scan is then used to generate a unique “IrisCode,” a cryptographic hash that acts as the user’s digital passport.

Key steps in the process:

1. Iris Scan: The user’s iris is scanned by the Orb.
2. IrisCode Generation: The Orb’s software uses the scan to create a unique IrisCode. This IrisCode is a non-personally identifiable cryptographic hash and is not the original iris image itself.
3. Proof of Uniqueness: The system checks the new IrisCode against its database of existing IrisCodes to ensure the user is not a duplicate.
4. World ID Issuance: Once uniqueness is verified, the user is issued a World ID.
5. Token Distribution: As part of its goal for global financial inclusion, verified users can receive a grant of WLD tokens, which are distributed periodically.

The process is designed to be privacy-preserving. Worldcoin claims that the Orb deletes the original iris images by default after generating the IrisCode. This claim has been the subject of both audits and public scrutiny. In 2024, a security firm, Trail of Bits, conducted a specialized audit of the Orb’s software, which concluded that the audited version of the software does not retain or exfiltrate personally identifiable information besides the IrisCode from the device.

Brief History

The Worldcoin project was co-founded by Sam Altman, the CEO of OpenAI, and Alex Blania, a former physicist. Their vision for the project was born from a recognition that as AI becomes more powerful and pervasive, a secure way to distinguish humans from AI is vital. The project officially launched in 2021, though its public rollout and token generation event occurred in July 2023.

The project’s early days were marked by a period of quiet development and a focus on building the necessary hardware and software. The iconic Orb devices were designed and deployed to various locations around the world to begin the process of “Orb-ing” people. This phase was a large-scale, real-world experiment to test the scalability and logistics of a global biometric-based identity system. By early 2023, the project had reportedly onboarded over 2 million unique users from more than 35 countries during its beta phase.

The public launch in mid-2023 brought significant attention, and the WLD token was listed on major cryptocurrency exchanges. While the initial token distribution model of providing free WLD to verified users created a surge in sign-ups, it also sparked a great deal of debate and scrutiny from regulators and privacy advocates in several countries. The project’s team, Tools for Humanity, a San Francisco- and Munich-based company, has been actively working to address these concerns. They have emphasized their use of advanced cryptographic techniques like zero-knowledge proofs to protect user privacy.

Distinctive Features

Worldcoin’s approach to digital identity and finance is unique, setting it apart from other crypto projects. Its core features are centered on addressing the emerging challenges of the AI era.

• Proof of Personhood: Worldcoin’s most distinctive feature is its use of biometrics—specifically, iris scanning—to create a “proof of personhood” or “proof of humanity.” This stands in stark contrast to traditional digital identity solutions that rely on online accounts, which are susceptible to Sybil attacks (where a single entity creates multiple fake identities).
• Global Access and Financial Inclusion: The project’s mission is to provide a digital identity and access to a financial network to everyone on the planet, including the billions of “unbanked” individuals. By distributing WLD tokens for free to verified individuals, it aims to create a new economic paradigm and enable widespread participation in the crypto economy without requiring initial investment.
• Privacy-Preserving Technology: Despite using biometric data, Worldcoin employs advanced cryptographic techniques to protect user privacy. It uses zero-knowledge proofs (ZKPs) to allow a user to prove they are a unique human without revealing their actual identity or personal data to the service they are interacting with.
• On-chain Identity: World ID is designed to be an on-chain identity credential, meaning it is stored on a decentralized network. This makes it resistant to censorship and manipulation by a single authority.

Governance

The Worldcoin project’s governance is structured to evolve toward a decentralized, community-driven model. Initially, the project was managed by Tools for Humanity, a company that developed the Orb and the core technology. However, the long-term vision is for the Worldcoin protocol to be governed by its community.

The Worldcoin Foundation, a non-profit organization, plays a central role in this transition. The Foundation is responsible for overseeing the protocol’s development, treasury management, and facilitating the shift toward full decentralization. The WLD token is also a governance token, meaning holders can participate in voting on key protocol decisions.

A tweet from a prominent crypto analyst, @DeFiLlamaInsider, highlighted this evolution, stating, “Interesting to see how Worldcoin’s governance evolves. The path from a centralized company like Tools for Humanity to a truly decentralized DAO will be a critical test for the entire DeFi space.” This sentiment underscores the ongoing debate and importance of achieving genuine decentralization in the crypto world.

The project’s governance model aims to balance the need for initial coordination and development with the long-term goal of a censorship-resistant, community-owned network. The transition involves gradually ceding control to the community, allowing token holders and World ID holders to have a say in the protocol’s future.
