世界幣：區塊鏈技術隱私和安全危險的警示故事

區塊鏈技術已成為變革資料管理的工具，但像世界幣這樣的案例凸顯了實施損害隱私和安全的解決方案的危險。

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.

區塊鏈技術確實徹底改變了我們管理資料的方式，但最近的專案（例如 Worldcoin）揭露了實施損害隱私和安全的解決方案時的潛在風險。這項旨在透過生物辨識掃描驗證用戶「人性」的企業引起了人們對用戶個人資料保存的嚴重擔憂。

Centralization and Opacity: A fundamental contradiction

集權與不透明：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.

儘管世界幣聲稱遵循去中心化原則，但它在中心化基礎設施上運行，其中只有一組封閉的節點控制網路。這種方法違背了公共區塊鏈固有的透明度精神，將數百萬用戶的生物識別數據變成了外部攻擊和內部濫用的簡單目標。當管理像個人獨特特徵這樣敏感的資訊時，黑盒子沒有立足之地。

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

零知識證明（ZK-Proofs）的虛假安慰

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.

儘管世界幣嚴重依賴 ZK 證明，允許在不暴露其內容的情況下進行資料驗證，但該技術並不能完全解決生物識別資訊的安全儲存問題。僅僅依賴這個工具是不夠的，特別是在仍然需要存取資料來產生證明的情況下。這顯示僅靠技術承諾並不足以保證隱私。

Risks of centralized data storage

集中式資料儲存的風險

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.

生物特徵資料的集中儲存會產生結構性漏洞。最近的歷史提供了令人震驚的例子，例如 Fractal ID 的案例，該公司在 2024 年遭受了重大洩露。就世界幣而言，集中環境中敏感資料的累積使用戶始終處於風險狀態。

The fragility of consent and trust in Worldcoin

世界幣的同意與信任的脆弱性

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.

世界幣的模式依賴對其負責任地處理生物識別數據的能力的隱含信任，但該公司缺乏透明度和追蹤記錄，這使得人們很難相信這一點。 「一旦模型訓練完成」就刪除資料之類的承諾是不夠的，因為該專案的歷史充滿了矛盾和明顯無視基本隱私標準。

Towards responsible management of digital identity

邁向負責任的數位身分管理

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.

顯然，我們需要更強大的解決方案來管理數位身分。將 ZK 證明等技術與完全同態加密 (FHE) 結合可以提供更好的保護。這種方法允許對加密資料執行操作而無需解密，從而確保處理每個階段的隱私。然而，這些工具的發展必須伴隨著明確的法規和公共監督機制，以防止過去的錯誤重演。

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.

世界幣不僅未能保護用戶的生物辨識數據，而且還凸顯了將擴張和行銷置於道德和安全之上的危險。這對科技業來說是一個迫切的教訓：我們不能以所謂創新的名義犧牲隱私。通往真正去中心化數位身分的道路必須以透明度、安全性和對使用者權利的絕對尊重為指導。如果沒有這些保證，像 WLD 這樣的專案只會提醒我們不能再犯錯。
