为支持保护隐私的数字身份解决方案，我们已将零知识证明（ZKP）库开源。零知识证明是一种强大的密码学工具，允许用户在无需共享额外个人数据的情况下，验证特定信息（例如证明其年龄已满 18 岁）。通过将该代码库公开，我们旨在支持： * **用户：** 提供更安全、更具私密性的数字体验。 * **企业：** 简化以隐私为核心的验证工具的集成。 * **开发者与研究人员：** 提供一套高效、高性能的工具包，用于构建和创新以隐私为中心的应用程序。此次发布符合欧盟即将实施的《eIDAS 条例》，该条例鼓励在欧盟数字身份钱包（EUDI Wallet）中集成隐私保护技术。通过分享这些工具，我们旨在加速欧盟及全球范围内安全且以隐私为先的基础设施建设。我们诚邀社区探索我们的代码库并开始构建：https://github.com/google/longfellow-zk

谷歌近期开源了其零知识证明（ZKP）库，旨在支持符合欧盟法规的年龄认证。该公告在 Hacker News 上引发了激烈的辩论，用户对该技术的有效性及其实施方式提出了质疑。批评者认为，零知识证明往往被过度吹捧，并指出作为服务提供方的谷歌依然能显著洞察用户数据。参与讨论的用户提出了零知识证明在实际应用中面临的挑战，例如如何防止证明被重复使用以及潜在的滥用风险。争论的一个主要焦点在于这对互联网自由的影响；一些用户担心此类系统会助长内容访问限制，从而可能阻碍年轻用户获取信息。讨论还触及了监控资本主义这一更宏大的背景。许多贡献者认为，只要追踪器仍在网络上持续收集数据，仅靠技术隐私解决方案是远远不够的。尽管有人捍卫“最小权限原则”是迈向更高安全性的积极一步，但也有人持怀疑态度，认为年龄验证强制令是大公司巩固权力的工具，而对普通公民的隐私担忧漠不关心。

Today, we open sourced our Zero-Knowledge Proof (ZKP) libraries, fulfilling a promise and building on our partnership with Sparkasse to support EU age assurance.

Open sourcing these powerful cryptographic tools will make it much easier for private and public sector developers to build their own privacy-enhancing applications and digital ID solutions, meeting an urgent need.

In layperson’s terms, ZKP makes it possible for people to prove that something about them is true without exchanging any other data. So, for example, a person visiting a website can verifiably prove he or she is over 18, without sharing anything else at all.

The goal of sharing ZKP with the open source and cryptography communities reflects our commitment to helping all parties in the ecosystem:

Web and app users benefit from being inhabitants of a more private and secure digital ecosystem.
Businesses and other relying organizations of all sizes can easily leverage this open source solution to meet their privacy needs.
Developers can freely use the ZKP codebase to build privacy-focused applications.
Researchers can use this more efficient and performant ZKP implementation to help create new applications and uses of technology.

The European Union’s eIDAS Regulation set to take effect in 2026 encourages Member States to integrate privacy-enhancing technologies like ZKP into the European Digital Identity Wallet (“EUDI Wallet”). With our commitment to making these ZKP tools openly available, Member States can integrate this into their future EUDI Wallets, accelerating their development.

We're so excited for this new chapter for Zero-Knowledge Proofs and invite you to explore the ZKP codebase on https://github.com/google/longfellow-zk.
