Sam Altman's Worldcoin launches to prove you're human in an AI world

Sam Altman helped unleash AI that can mimic humans. Now he wants to scan your eyeballs to prove you are one.

OpenAI CEO Sam Altman and his startup Tools for Humanity officially launched Worldcoin. Alongside the protocol launch, its native WLD token went live on major exchanges including Binance, Huobi, and Bybit, trading around $2.26 shortly after launch.

Staring into the silver sphere

The premise of Worldcoin rests on a simple problem: as generative AI explodes, telling bots from real people online is becoming nearly impossible. Altman’s answer is World ID, a cryptographic "proof of personhood."

To get one, you have to look into a bowling-ball-sized chrome sphere called the Orb. The device scans your irises to verify you are a unique, living human. Worldcoin claims it does not store the raw images; instead, the scan is immediately converted into a specialized cryptographic hash and the photo is deleted.

Once verified, users receive a World ID stored on an Ethereum layer-2 network (OP Mainnet) and can claim free WLD tokens in their World App wallet. Tools for Humanity, which raised $115 million in Series C funding led by Blockchain Capital in May, handles the hardware and software development.

Scaling up to 35 cities amid heavy skepticism

Worldcoin racked up over 2 million signups during its multi-year beta, verifying roughly 40,000 individuals weekly in recent months. The project has already seen signups across countries like Kenya, Portugal, Spain, India, Argentina, and Chile.

With the commercial launch, Worldcoin is deploying 1,500 Orbs to 35 cities across 20 countries, including hubs like Tokyo, Seoul, Berlin, and New York. The company expects this deployment to boost signup capacity by more than fivefold.

Altman frames the project as laying the groundwork for a world remade by AI. If machine intelligence displaces human labor, a reliable proof of personhood could prevent fraud in AI-funded universal basic income (UBI) programs.

Yet the project faces intense pushback. Privacy advocates question the risks of biometric data collection, while reports from outlets like Bloomberg have highlighted aggressive signup tactics targeting lower-income populations in places like Indonesia and Ghana.

Why it matters

We think Worldcoin is addressing a very real problem, but using a method that will terrify privacy-conscious users. Proof of personhood will undoubtedly matter as generative agents flood the web, and developers can already tap the World ID SDK to stop spam or sybil attacks.

However, everyday users should probably think twice before trading their biometric data for a small bag of tokens. Your iris cannot be reset like a password. Even if the network only stores zero-knowledge hashes, placing complete trust in third-party Orb operators and custom hardware is a massive gamble.

Altman’s play is politically ambitious: use OpenAI to spark the AI revolution, then use Worldcoin to distribute the UBI safety net. But coupling biometric scans with crypto tokens looks suspiciously like classic Silicon Valley overreach. Until Worldcoin can satisfy aggressive regulators and suspicious privacy watchdogs, it will remain an uneasy social experiment rather than global public infrastructure.
