Notes

• Threshold zk identification protocol allows t members to jointly prove they know a secret
• This protocol avoids the registration and authentication of each member's public key, making it suitable for dynamic or untrusted environments
• The actual proof content, for example, can be 'we are proving we know the private key x'
• Applications include anonymous group authentication, decentralized identity systems, on-chain multi-signature control, IoT collaboration, cross-organization verification, etc.
• OSST protocol is non-interactive and does not depend on public shares, supporting asynchronous communication and dynamic member joining

• 门限零知识识别协议让 t 个成员联合证明他们共同知道某个秘密
• 此类协议避免了对每个成员公钥的注册与认证，适用于动态或去信任环境
• 实际证明的内容举例来说，可以是 “我们这些人联合起来，确实知道某个私钥 x”
• 应用场景包括匿名群体认证、去中心化身份系统、链上多签控制、IoT 协作、跨组织验证等
• OSST 协议是非交互式的，不依赖公开份额，支持异步通信和成员动态加入
