The Human Cost of Digital Currency: What Biometric Experiments in Web3 Reveal
As developments in Web3 technologies continue to unfold, new pathways for access and digital inclusion are being explored. However, initiatives involving biometric registration—such as Worldcoin—raise fundamental questions about consent, data usage, and long-term accountability. This article examines the ethical dimensions of such projects, highlighting the need for measured, respectful approaches to digital identity that support sustainable participation. This reflection also extends earlier commentary on the future of responsible innovation within decentralized ecosystems.

Introduction
Web3 technologies offer the potential to reshape the way people engage with digital tools, economies, and identities. These systems are often promoted as alternatives to centralized control, with an emphasis on openness and decentralization. However, not all innovations operate within the same ethical framework. The introduction of biometric tools within cryptocurrency ecosystems has prompted renewed conversations about fairness, data rights, and informed choice.
Case Overview: Worldcoin’s Iris Scanning Initiative
Worldcoin, co-founded by Sam Altman, introduced a device known as the "Orb" to scan individuals’ irises in exchange for cryptocurrency tokens (Winkless, 2022). Although the scan is not mandatory at the time of publication, and participation remains voluntary, the initiative has drawn scrutiny due to its implications for privacy, consent, and cross-border data governance.
Several national regulatory bodies have responded with caution. For instance, Spain’s data protection authority ordered the deletion of stored iris data, citing insufficient safeguards (El País, 2024). Similar actions occurred in Hong Kong and Argentina, where officials questioned whether biometric data collection practices met local legal and ethical standards (CryptoPotato, 2024; Cointelegraph, 2023).
What is notable is not only the technical design of the project, but where and how these systems have been introduced. Early deployment reportedly focused on regions with fewer legal protections and limited access to information about digital rights. This trend calls for a closer look at what forms of digital participation are being prioritized, and who bears the long-term consequences.
Responsible Innovation and the Question of Consent
In earlier reflections on Web3 (Lucky Star, 2025), I emphasized that true sustainability arises when systems are designed to uphold autonomy and respect—not simply when they scale rapidly. The pursuit of technological efficiency must remain anchored in meaningful participation, where individuals understand and consent to how their data is being used, and where alternative forms of access are made available.
The presence of biometric enrollment tools—even when presented as optional—raises foundational concerns. What begins as a voluntary engagement may evolve into systems that create indirect dependencies. Therefore, it is critical to ensure:
- Transparency in how data is collected, stored, and used
- Respect for individual autonomy, especially regarding irreversible data types such as biometrics
- Inclusive design that does not rely on asymmetrical access to information or digital protections
Alternative Frameworks: Building with Integrity
There are proven alternatives to biometric-based digital identity. Decentralized identifiers, cryptographic proof systems, and local governance models provide pathways for access without requiring deeply personal data. Such approaches are increasingly recognized for their ability to balance security with self-determination.
Moving forward, it is essential to encourage initiatives that reflect both technological rigor and ethical responsibility. Building systems that earn trust—rather than extract value—will lead to more stable and collaborative digital ecosystems. This principle applies not only to start-ups but also to policy leaders, developers, and organizations tasked with shaping future norms.
Conclusion: A Measured Approach to Digital Participation
Digital ecosystems are not inherently neutral—they reflect the choices and values of those who design them. As global attention turns to scalable identity solutions, decision-makers must avoid practices that reproduce asymmetries in control or understanding. The conversation must remain open to diverse approaches—especially those rooted in long-term stewardship rather than short-term acceleration.
By placing careful design, local agency, and data dignity at the forefront, it is possible to foster more durable forms of participation in Web3. This does not mean halting experimentation; it means advancing with care. Sustainable digital ecosystems will emerge not from ubiquity alone, but from frameworks that respect the rights and contributions of all involved.
