具有增量安全性的双层区块链时间戳公证
Two-tier blockchain timestamped notarization with incremental security
摘要：
数字公证是现代区块链解决方案提供的最有前途的服务之一。我们提出了一个数字公证设计与增量的安全性和成本降低相对于当前的解决方案。该服务的客户通过三个步骤获得证据。在第一步中，几乎立即收到证据，但需要大量的信任。在第二步中，需要较少的信任，但几秒钟后就会收到证据。最后，在第三步中，通过公共区块链在几分钟内收到证据。
英文摘要：
Digital notarization is one of the most promising services offered by modern blockchain-based solutions. We present a digital notary design with incremental security and cost reduced with respect to current solutions. A client of the service receives evidence in three steps. In the first step, evidence is received almost immediately, but a lot of trust is required. In the second step, less trust is required, but evidence is received seconds later. Finally, in the third step evidence is received within minutes via a public blockchain.
