What is Worldcoin? Recently, I’ve been getting more questions about this project. In simple terms, it’s a cryptocurrency project launched by Sam Altman and a research company called Tools for Humanity.

The biggest feature of Worldcoin is using biometric authentication, especially iris scans, to verify whether users are real humans. It aims to prevent impersonation and combat bots. In the field of digital identity, I think this is a pretty advanced approach.

It collects data using a scanner called Orb and records it on the blockchain in a privacy-preserving manner. The operation runs on the Optimism mainnet. Worldcoin is not just a token; it’s part of a larger ecosystem that proves you are a human (Proof of Personhood).

What’s interesting is that it also includes an experimental aspect of UBI (Universal Basic Income). By giving each user one token, it tries to implement a one-person-one-vote system.

Regarding the native token WLD, it functions for governance, staking, and identity verification. Its supply model is fixed, with a focus on airdrops to early adopters. Transaction fees are relatively low.

Of course, there are risks. Since it handles biometric data, privacy concerns are unavoidable. Additionally, the regulatory environment is still quite uncertain. The concept of Proof of Personhood itself may face challenges in gaining widespread acceptance.

On the other hand, it offers a new approach to digital identity and human verification. It supports biometric authentication while protecting privacy. It also has backing from prominent industry figures.

If I had to sum up what Worldcoin is in one phrase, it’s an experimental project that combines bot prevention and digital identity. In a space where cryptocurrency, AI, and privacy intersect, it’s worth paying attention to how it develops.
