世界币：区块链技术隐私和安全危险的警示故事

区块链技术已成为变革数据管理的工具，但像世界币这样的案例凸显了实施损害隐私和安全的解决方案的危险。

Blockchain technology has indeed revolutionized the way we manage data, but recent projects like Worldcoin have brought to light the potential risks when implementing solutions that compromise privacy and security. This venture, which aims to verify users’ “humanity” through biometric scans, raises serious concerns about the preservation of users’ personal data.

区块链技术确实彻底改变了我们管理数据的方式，但最近的项目（例如 Worldcoin）暴露了实施损害隐私和安全的解决方案时的潜在风险。这项旨在通过生物识别扫描验证用户“人性”的企业引起了人们对用户个人数据保存的严重担忧。

Centralization and Opacity: A fundamental contradiction

集权与不透明：根本矛盾

Despite claiming to follow decentralized principles, Worldcoin operates on a centralized infrastructure where only a closed group of nodes controls the network. This approach, which goes against the ethos of transparency inherent in public blockchains, turns the biometric data of millions of users into easy targets for external attacks and internal abuses. There is no place for black boxes when managing information as sensitive as a person’s unique traits.

尽管世界币声称遵循去中心化原则，但它在中心化基础设施上运行，其中只有一组封闭的节点控制网络。这种方法违背了公共区块链固有的透明度精神，将数百万用户的生物识别数据变成了外部攻击和内部滥用的简单目标。当管理像个人独特特征这样敏感的信息时，黑匣子没有立足之地。

The false comfort of Zero-Knowledge Proofs (ZK-Proofs)

零知识证明（ZK-Proofs）的虚假安慰

Although Worldcoin heavily relies on ZK-proofs, which allow data verification without exposing its content, this technology does not fully address the secure storage of biometric information. Depending exclusively on this tool is insufficient, especially in a context where access to the data is still required to generate the proofs. This shows that technological promises alone are not enough to guarantee privacy.

尽管世界币严重依赖 ZK 证明，允许在不暴露其内容的情况下进行数据验证，但该技术并不能完全解决生物识别信息的安全存储问题。仅仅依赖这个工具是不够的，特别是在仍然需要访问数据来生成证明的情况下。这表明仅靠技术承诺并不足以保证隐私。

Risks of centralized data storage

集中式数据存储的风险

The centralized storage of biometric data creates structural vulnerabilities. Recent history provides alarming examples, like the case of Fractal ID, which suffered a major breach in 2024. Even platforms with the most controlled designs are not exempt from errors that compromise personal information. In the case of Worldcoin, the accumulation of sensitive data in a centralized environment places users in a constant state of risk.

生物识别数据的集中存储会产生结构性漏洞。最近的历史提供了令人震惊的例子，例如 Fractal ID 的案例，该公司在 2024 年遭受了重大泄露。即使是设计最受控制的平台也无法避免泄露个人信息的错误。就世界币而言，集中环境中敏感数据的积累使用户始终处于风险状态。

The fragility of consent and trust in Worldcoin

世界币的同意和信任的脆弱性

Worldcoin’s model depends on implicit trust in its ability to responsibly handle biometric data, but the company’s lack of transparency and track record make this difficult to believe. Promises like deleting data “once the models are trained” are insufficient, as the project's history is marked by contradictions and an apparent disregard for basic privacy standards.

世界币的模式依赖于对其负责任地处理生物识别数据的能力的隐含信任，但该公司缺乏透明度和跟踪记录，这使得人们很难相信这一点。 “一旦模型训练完成”就删除数据之类的承诺是不够的，因为该项目的历史充满了矛盾和明显无视基本隐私标准。

Towards responsible management of digital identity

迈向负责任的数字身份管理

It is clear that we need more robust solutions for managing digital identity. Combining technologies like ZK-proofs with fully homomorphic encryption (FHE) can offer greater protection. This approach would allow operations to be performed on encrypted data without needing to decrypt it, ensuring privacy at every stage of processing. However, the development of these tools must be accompanied by clear regulations and public oversight mechanisms to prevent past mistakes from being repeated.

显然，我们需要更强大的解决方案来管理数字身份。将 ZK 证明等技术与完全同态加密 (FHE) 相结合可以提供更好的保护。这种方法允许对加密数据执行操作而无需解密，从而确保处理每个阶段的隐私。然而，这些工具的开发必须伴随着明确的法规和公共监督机制，以防止过去的错误重演。

Worldcoin has not only failed in protecting its users’ biometric data but has also highlighted the dangers of prioritizing expansion and marketing over ethics and security. This is an urgent lesson for the tech industry: we cannot sacrifice privacy in the name of so-called innovation. The path to a truly decentralized digital identity must be guided by transparency, security, and absolute respect for users’ rights. Without these guarantees, projects like WLD will be little more than reminders of mistakes we cannot afford to repeat.

世界币不仅未能保护用户的生物识别数据，而且还凸显了将扩张和营销置于道德和安全之上的危险。这对科技行业来说是一个紧迫的教训：我们不能以所谓创新的名义牺牲隐私。通往真正去中心化数字身份的道路必须以透明度、安全性和对用户权利的绝对尊重为指导。如果没有这些保证，像 WLD 这样的项目只会提醒我们不能再犯错误。
