Odaily星球日报讯 XION 宣布正式上线 DKIM 模块与 ZK 模块，作为将邮件认证密钥（DKIM）直接存储在链上的区块链，在协议层实现零知识验证的消费级 L1 公链。
XION 指出，现有的邮件验证方案（包括 zkEmail 等项目）均依赖中心化 DNS 服务器获取加密密钥，当邮件服务商轮换密钥时，旧的验证即失效，且无历史记录可查。XION 的 DKIM 模块将这些密钥永久存储在链上状态中，彻底消除了对中心化 DNS 基础设施的依赖。其 ZK 模块则在协议层实现零知识证明验证，效率为智能合约方案的 10 倍，两者协同工作，使用户可以证明邮件中的任何信息，而无需暴露邮件本身。
XION 表示，目前约 61% 的员工目睹不当行为仍保持沉默，因为传统选择往往是 “匿名但被忽视 ”或 “发声但可能失业 ”。借助上述基础设施，XION 实现了多种应用场景，包括：
匿名举报与职场评价（证明在职身份而不暴露个人信息）
无需助记词的钱包恢复（邮件作为备份密钥）
购买行为与证书验证（无需过度分享个人信息）
信任托管的票务转售与保险理赔等。
目前 XION 月活跃用户超过 80 万，已有 Uber、Amazon、BMW 等 150 多个品牌接入。
