论文摘要
本文考虑了受跨链交换启发的分布式系统模型中的经典状态机器复制（SMR）问题。我们提出了一种适合此模型的新型SMR协议。每个状态机器过渡都采用$ o（n）$消息延迟，其中$ n $是活跃参与者的数量，其中任何数字都可以是拜占庭。该协议使使用路径签名的新颖使用以保持复制品一致。该协议设计将应用程序逻辑与容错分开，提供了一种系统的方式，可以使用更原则的方法替换复杂的临时跨链协议。
This paper considers the classical state machine replication (SMR) problem in a distributed system model inspired by cross-chain exchanges. We propose a novel SMR protocol adapted for this model. Each state machine transition takes $O(n)$ message delays, where $n$ is the number of active participants, of which any number may be Byzantine. This protocol makes novel use of path signatures to keep replicas consistent. This protocol design cleanly separates application logic from fault-tolerance, providing a systematic way to replace complex ad-hoc cross-chain protocols with a more principled approach.
