ZK-Proofs 在去中心化身分識別產品中越來越受歡迎，但技術複雜性阻礙了政府的採用

根據 Cointelegraph 報道，零知識（ZK）證明是一種在不洩露資訊具體內容的情況下驗證資訊的方法，在創建去中心化身份產品中受到歡迎。

Decentralized identity (DID) solutions have been gaining traction, particularly with the use of zero-knowledge (ZK) proofs. However, the technical complexity of ZK-proofs poses challenges in government and institutional adoption.

去中心化身分（DID）解決方案一直受到關注，特別是在使用零知識（ZK）證明的情況下。然而，ZK 證明的技術複雜性給政府和機構的採用帶來了挑戰。

According to Ingo Rübe, CEO and co-founder of KILT Protocol, decentralized identifiers, such as biometric data, can be selectively shared and verified on-chain using Merkle Trees. This method, which is easily understood by computer scientists, offers greater ease, speed, and efficiency compared to ZK-proofs.

KILT Protocol 執行長兼聯合創始人 Ingo Rübe 表示，可以使用 Merkle Trees 選擇性地在鏈上共享和驗證去中心化標識符，例如生物識別數據。這種方法很容易被電腦科學家理解，與 ZK 證明相比，它提供了更大的簡單性、速度和效率。

Rübe also highlights the risks associated with the open-source software commonly used in ZK solutions. Companies often rely on third-party libraries without clear accountability, which could lead to massive data breaches.

Rübe 也強調了 ZK 解決方案中常用的開源軟體的相關風險。公司通常依賴第三方函式庫而沒有明確的責任，這可能導致大規模資料外洩。

He emphasizes the importance of using public permissionless blockchains to store credential validity, enabling users to own and create their digital identifiers, which are stored locally and verified through decentralized networks.

他強調了使用公共無許可區塊鏈來儲存憑證有效性的重要性，使用戶能夠擁有和創建他們的數位標識符，這些標識符儲存在本地並通過去中心化網路進行驗證。

In 2022, the World Wide Web Consortium (W3C) developed a standard for decentralized identity solutions, underscoring the growing interest in this field.

2022 年，萬維網聯盟 (W3C) 制定了去中心化身分解決方案標準，凸顯了人們對該領域日益增長的興趣。

Despite the technical barriers, several entities are exploring ZK-powered identity solutions. In October 2024, Buenos Aires announced the rollout of decentralized identification for residents using ZKsync Era.

儘管存在技術障礙，一些實體仍在探索 ZK 支援的身份解決方案。 2024 年 10 月，布宜諾斯艾利斯宣布使用 ZKsync Era 為居民推出去中心化身分識別。

Additionally, on October 17, World, formerly known as Worldcoin (WLD), introduced the next generation of biometric data-collecting orbs and the World ID Credentials program. This initiative will allow individuals with NFT-enabled government passports to register their identity in the World system.

此外，10 月 17 日，World（原名 Worldcoin (WLD)）推出了下一代生物辨識資料收集球和 World ID 憑證計畫。該舉措將允許持有支持 NFT 的政府護照的個人在世界系統中註冊其身分。

Rübe notes that different approaches to decentralized identity solutions, including ZK-proofs, are suitable for various use cases. However, he likens the use of ZK-proofs for decentralized identity to “taking a bazooka and trying to kill a fly,” indicating that simpler methods might be more effective for certain applications.

Rübe 指出，去中心化身分解決方案的不同方法（包括 ZK 證明）適用於各種用例。然而，他將使用 ZK 證明來實現去中心化身份比作“拿著火箭筒試圖殺死一隻蒼蠅”，這表明更簡單的方法對於某些應用程式可能更有效。
