Notes

• PTX protocol uses zkSNARK for asynchronous, non-interactive domain control validation, replacing traditional ACME
• Anchors proofs via DNS TXT records, eliminating need for active web servers or open ports
• Circuit design binds ephemeral secrets to scoped metadata, enabling client-side verification and privacy
• Implemented with Groth16 and Poseidon, only 1,756 constraints, verification under 15ms
• Mitigates replay attacks, suitable for serverless, static, and air-gapped deployments
• Provides privacy-preserving alternative for identity assertions in decentralized environments

• PTX协议利用zkSNARK实现异步、非交互式域控制验证，替代传统ACME协议
• 通过DNS TXT记录锚定证明，无需活动Web服务器或开放网络端口
• 电路设计将临时秘密绑定到范围元数据，支持客户端验证和隐私保护
• 使用Groth16和Poseidon实现，仅1,756约束，验证时间低于15ms
• 有效缓解重放攻击，适用于无服务器、静态和隔离部署环境
• 为去中心化环境中的身份断言提供隐私保护替代方案
