Worldcoin, renamed simply “World” in October 2024, is a project co-founded by OpenAI CEO Sam Altman. It aims to give every person a way to prove online that they are a unique human and not a bot, using an iris-scanning device called the Orb. WLD is the network’s token. Verified people receive it in periodic grants, and it is also used for governance and to pay fees on the project’s own blockchain, World Chain. The worldcoin coin is one of crypto’s most debated assets: it sits where AI, biometrics and privacy law meet, and that has brought both large partnerships and orders from regulators in several countries.

Key takeaways
- World is built by Tools for Humanity, co-founded in 2019 by Sam Altman, Alex Blania and Max Novendstern. WLD launched in July 2023.
- The Orb turns an iris scan into an encrypted code that proves you’re a unique person. You get a “World ID,” not a public identity.
- WLD has a 10 billion maximum supply. Only part of it circulates, and scheduled unlocks and user grants keep adding tokens to the market.
- Data-protection regulators in Spain, Portugal, Kenya, Hong Kong, Germany, Indonesia, Brazil and others have suspended, restricted or ordered changes to its operations.
- In 2025–2026 the project shifted toward the US and toward business deals (dating apps, video calls, e-signatures) built on its proof-of-human check.
History and founders
Tools for Humanity (TFH) was founded in 2019 by Sam Altman, Alex Blania (now CEO) and Max Novendstern. The founding idea was that as AI makes bots indistinguishable from people, the internet will need a privacy-preserving way to tell them apart. Some of the resulting network’s value could even be shared out like a universal basic income.
Key milestones:
- 2021–2022: TFH runs Orb pilots, mostly in developing countries. Journalists criticize the recruitment methods and the lack of clear consent.
- July 2023: The WLD token launches alongside World App. Within days, regulators in Kenya, France, the UK and elsewhere open inquiries, and Kenya suspends sign-ups.
- 2024: Spain and Portugal order temporary halts, and Hong Kong’s privacy regulator orders operations there to stop. TFH moves iris-code storage to a secure multi-party computation system and lets users delete their data.
- October 2024: The project rebrands to “World,” launches World Chain (an Ethereum layer 2) and shows a redesigned Orb.
- 2025: The US launch begins with Orbs in cities including Atlanta, Austin, Los Angeles, Miami, Nashville and San Francisco. A smaller “Orb Mini” is announced. Indonesia suspends the service, and Kenya’s High Court orders collected data deleted.
- 2026: World reports nearly 18 million Orb-verified people across about 160 countries and more than 30 million World App users. It signs integrations with consumer platforms such as Tinder and Zoom and cuts staff as it pursues enterprise deals.
These user counts come from the company and have run well behind its early target of a billion people.
How Worldcoin works
World ID and the Orb
At an Orb, the device photographs your face and irises, checks that you’re a live human, and derives an “iris code,” a numeric fingerprint of your iris pattern. That code is compared against everyone already enrolled. If it’s new, you receive a World ID credential in World App. Under the current design, the raw images are sent encrypted to your phone and deleted from the Orb, and the iris code is split into encrypted fragments held by separate parties, so no single database holds it in full.
Zero-knowledge proofs
When an app asks “is this a unique human?”, World App answers with a zero-knowledge proof. The app learns that you hold a valid World ID and haven’t already used it for that action, but not who you are or which Orb verified you.
World App and World Chain
World App is a self-custody wallet with built-in mini-apps. World Chain is an OP Stack layer 2 on Ethereum (see our layer-2 guide) that gives verified humans priority access and some free gas, a deliberate defense against bot spam.
Tokenomics
| Item | Detail |
|---|---|
| Maximum supply | 10 billion WLD |
| Community allocation | 75% (user grants, ecosystem, operations) |
| TFH team | ~9.8% |
| TFH investors | ~13.5% |
| TFH reserve | ~1.7% |
| Insider unlocks | Extended in 2024 so team and investor tokens release over five years rather than three |
| Circulating supply | Well under half of the max. Check a live tracker, because it rises every month. |
The main thing to understand is supply growth. Grants to verified users, market-maker loans and insider unlocks all add WLD to circulation, and the circulating figure has grown several times over since launch. If demand doesn’t keep pace, the price falls even when the project is growing. Our tokenomics guide explains how to read an unlock calendar.
The controversy
- Biometric privacy: Even with deletion and encrypted iris codes, critics argue that an iris-derived identifier is permanent. Unlike a password, you can’t change your eyes if something leaks.
- Regulatory pushback: European data-protection authorities (Spain, Portugal, Bavaria in Germany), Kenya, Hong Kong, Indonesia, Brazil and South Korea have each investigated, fined, suspended or restricted parts of the service. Brazil, for example, objected to paying people in tokens for scans, arguing it undermines free consent. See our regulation-by-country guide.
- Exploitation concerns: Early enrollment focused on lower-income countries, where a token grant was worth a meaningful sum.
- Centralization: TFH designs and makes the Orbs, so users must trust its hardware and software.
- Black-market accounts: Reports have described verified accounts being bought and sold, which undermines the “one person, one ID” promise.
World ID vs other ways to prove you’re human
| Method | What it checks | Main weakness |
|---|---|---|
| CAPTCHAs | Behavior that bots find hard | Modern AI solves most of them |
| Government ID / KYC | Legal identity | Exposes your full identity to every service and excludes people without documents |
| Phone-number checks | Control of a SIM | SIMs are cheap to buy in bulk |
| Social-graph systems | Vouching by other users | Slow to scale and can be gamed by groups |
| World ID | Uniqueness of a living iris | Needs special hardware and biometric trust |
World’s argument is that it is the only option that is both anonymous and resistant to someone creating thousands of accounts. Critics answer that it trades one privacy risk for another.
How to get a World ID, buy WLD or earn it
Getting verified
- Install World App from the official app store listing. Check that the publisher is Tools for Humanity.
- Use the in-app map to find an Orb location and book a slot where that’s offered.
- Complete the scan, which takes a few minutes. The World ID is stored on your phone, so back up the app as prompted.
- Where grants are offered, claim WLD in the app. Grant availability and size vary by country and have changed several times.
Buying WLD
- Centralized exchanges: Many large exchanges list WLD. US availability is narrower, so check your platform.
- On-chain: WLD trades on World Chain and Optimism. If you buy on-chain, copy the contract address from World’s official docs or a major tracker.
Safety checklist
- Never let anyone “help” you verify by holding your phone. Sold or hijacked World IDs are a known problem.
- Ignore DMs offering “Orb-free verification” or WLD airdrops. They’re phishing.
- Remember that verification is optional. You can buy and hold WLD without ever scanning your iris.
Pros and cons
Pros
- Addresses a real and growing problem: telling humans from AI agents and bots online
- One of the largest crypto user bases, with real third-party integrations
- Uses advanced privacy tools: zero-knowledge proofs and split, encrypted iris codes
- Strong funding and very high public visibility
Cons
- Biometric collection creates permanent regulatory and reputational risk
- Steady token dilution from grants and unlocks
- Depends on one company’s hardware and continued funding
- User growth has lagged its stated goals
Is the worldcoin coin a good investment?
Think in scenarios rather than targets. Bull case: proof-of-human becomes standard for dating, social media and AI agents, World ID becomes the default, and fee demand on World Chain absorbs new supply. Base case: verifications grow steadily but unlocks keep the price under pressure, and WLD trades with the wider AI-token sector. Bear case: a major regulatory ban or data incident, or a big-tech competitor launching its own proof-of-personhood, and the token keeps sliding as supply expands. Our WLD price prediction sets out the numbers, and best AI crypto compares it with other AI tokens.

FAQ
Is Worldcoin safe to use?
The design is more privacy-protective than its early versions. Images are deleted from the Orb, iris codes are encrypted and split across parties, and apps only see zero-knowledge proofs. But you are still trusting TFH’s hardware and code, and several regulators have found problems with consent or data handling. If biometric risk worries you, you can hold WLD without verifying.
Is Worldcoin the same as World?
Yes. In October 2024 the project renamed itself “World” and the app “World App.” The token kept the WLD ticker, and many exchanges and articles still call it Worldcoin. Tools for Humanity is the company that builds the technology. The World Foundation is the non-profit that oversees the protocol and token.
How many people have verified with World ID?
The company reported nearly 18 million Orb-verified people in spring 2026, with more than 30 million World App users overall. These are company figures and include accounts that are no longer active. The total remains far below Tools for Humanity’s goal of a billion people, which is one reason it now focuses on partnerships in a few large markets.
Can I get free WLD?
Verified users in eligible countries have received periodic WLD grants through World App, but amounts and eligibility have changed over time and vary by jurisdiction. Grants are not guaranteed, and sites promising “free WLD” outside the official app are almost always scams.
