TLSNotary中心化预言机（3） 下一代技术----PADVA

1. 概念说明

Persistent and Accountable Domain Validation (PADVA) is a next-generation TLS notary service. PADVA combines the advantages of previous proposals, enhancing them, introducing novel mechanisms, and leveraging a blockchain platform which provides new features. PADVA keeps notaries auditable and accountable, introduces service-level agreements and mechanisms to enforce them, relaxes availability requirements for notaries, and works with the legacy TLS ecosystem.

PADVA 是下一代TLS notary技术服务，PAVDA包含之前投案、建议，加强它们，引入新的机制并影响区块链平台的诸多特性。 PADVA使公证数据保持可审计性和责任感，引入服务级别协议和机制来执行这些协议，放宽公证人的可用性要求，并与LS生态经济系统合作。
