Worldcoin launch sparks debate among crypto community

The Polarizing Effect of Worldcoin’s Blockchain-Based Digital Passport Platform

The launch of Worldcoin, a blockchain-based digital passport platform, has generated both excitement and controversy within the cryptocurrency community. The project introduces a privacy-preserving digital identity known as World ID, which is secured through biometric proof-of-personhood. While Worldcoin has gained support from major exchanges like Binance, questions have been raised regarding centralization, privacy, and security.

Worldcoin: A Digital Identity Ecosystem

Worldcoin, released on July 24, offers users a privacy-centric digital identity known as World ID, along with an associated ecosystem token called WLD. To join the Worldcoin ecosystem, users must provide a scan of their iris using specialized Orb hardware devices. This biometric proof-of-personhood is cryptographically secured and used to create a unique World ID, ensuring online authenticity while maintaining complete privacy.

The World ID concept aims to store the global digital passport locally on users’ mobile devices, allowing them to prove their identity in a privacy-centric manner. Zero-knowledge proofs (ZK-proofs) are utilized to protect sensitive data, such as biometric information, KYC (Know Your Customer) data, and AML (Anti-Money Laundering) data.

Vitalik Buterin’s Analysis: The Potential and Pitfalls of Proof-of-Personhood

Ethereum co-founder Vitalik Buterin commented on Worldcoin’s launch, discussing the potential of biometric proof-of-personhood. In a blog post, Buterin delved into the technical aspects of such blockchain protocols and their potential benefits and drawbacks. He acknowledged Worldcoin’s uniqueness in utilizing highly sophisticated biometrics, specifically scanning users’ irises with the specialized Orb hardware.

While recognizing the opportunities presented by proof-of-personhood protocols, Buterin also raised concerns about privacy and security. He highlighted risks such as potential privacy leaks, erosion of online anonymity, coercion by authoritarian governments, and the challenge of maintaining both security and decentralization.

Industry Figures Weigh In: Jack Dorsey, Anita Posch, and Yoni Assia

Twitter co-founder Jack Dorsey described Worldcoin’s attempt at global scale alignment as “cute,” implying skepticism towards the project’s ambitious goals. Bitcoin advocate Anita Posch questioned the centralized nature of the project, expressing concerns about managing large amounts of sensitive data linked to individuals’ financial transactions.

Yoni Assia, the founder of eToro, mentioned that Worldcoin resembled his own GoodDollars digital universal basic income platform. This implies that Worldcoin is following a similar concept, and Assia expressed curiosity about the growth of blockchain-based UBI implementations.

Worldcoin’s Implementation and User Base

Worldcoin’s white paper documentation reveals that the protocol was initially deployed on Polygon during its beta phase. The current version runs on the Ethereum mainnet, leveraging a scalable batching architecture through the Optimism layer 2 protocol. Notably, the project already boasts a user base of over two million users.


Worldcoin’s blockchain-based digital passport platform has sparked discussions in the cryptocurrency community, with divided opinions on its centralization, privacy, and security aspects. While the project presents innovative solutions for privacy-preserving digital identity, concerns have been raised about the potential risks and ethical implications surrounding biometrics and the management of sensitive data.

As the project evolves, addressing these concerns and finding a balance between privacy, security, and decentralization will be crucial for establishing Worldcoin’s credibility and fostering trust among users. The future of blockchain-based digital passports and their potential impact on identity verification and universal basic income remains an intriguing area to watch within the ever-expanding blockchain industry.
