ZK-Proofs 在去中心化身份产品中越来越受欢迎，但技术复杂性阻碍了政府的采用

据 Cointelegraph 报道，零知识（ZK）证明是一种在不泄露信息具体内容的情况下验证信息的方法，在创建去中心化身份产品中受到欢迎。

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.

去中心化身份（DID）解决方案一直受到关注，特别是在使用零知识（ZK）证明的情况下。然而，ZK 证明的技术复杂性给政府和机构的采用带来了挑战。

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 首席执行官兼联合创始人 Ingo Rübe 表示，可以使用 Merkle Trees 有选择地在链上共享和验证去中心化标识符，例如生物识别数据。这种方法很容易被计算机科学家理解，与 ZK 证明相比，它提供了更大的简便性、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 还强调了 ZK 解决方案中常用的开源软件的相关风险。公司通常依赖第三方库而没有明确的责任，这可能导致大规模数据泄露。

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.

他强调了使用公共无许可区块链来存储凭证有效性的重要性，使用户能够拥有和创建他们的数字标识符，这些标识符存储在本地并通过去中心化网络进行验证。

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

2022 年，万维网联盟 (W3C) 制定了去中心化身份解决方案标准，凸显了人们对该领域日益增长的兴趣。

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.

尽管存在技术障碍，一些实体仍在探索 ZK 支持的身份解决方案。 2024 年 10 月，布宜诺斯艾利斯宣布使用 ZKsync Era 为居民推出去中心化身份识别。

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)）推出了下一代生物识别数据收集球和 World ID 凭证计划。该举措将允许持有支持 NFT 的政府护照的个人在世界系统中注册其身份。

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，去中心化身份解决方案的不同方法（包括 ZK 证明）适用于各种用例。然而，他将使用 ZK 证明来实现去中心化身份比作“拿着火箭筒试图杀死一只苍蝇”，这表明更简单的方法对于某些应用程序可能更有效。
