论文摘要
交叉链通信允许在区块链之间传达信息。在交叉链通信的背景下，共识与一个区块链上的参与者如何确信远程区块链的状态有关。它描述了与源区块链相关联的当事方如何达成共识并与目标区块链进行通信，从而可以信任来自源区块链的信息。本文调查了交叉链通信协议，根据他们试图满足的顶级用法方案介绍它们：价值交换，交叉链消息传递和区块链固定。它分析了每个协议如何达到交叉链共识，做出了什么信任假设，它们在无许可和许可的区块链上下文中成功运作的能力以及该协议是否在跨区块链跨链链中提供了原子更新。
Crosschain communications allows information to be communicated between blockchains. Consensus in the context of crosschain communications relates to how participants on one blockchain are convinced of the state of a remote blockchain. It describes how parties associated with a source blockchain come to agreement and communicate with a destination blockchain such that information from the source blockchain can be trusted. This paper surveys crosschain communications protocols, presenting them based on the top-level usage scenarios they are trying to meet: value swapping, crosschain messaging, and blockchain pinning. It analyses how each protocol achieves crosschain consensus, what trust assumptions are made, their ability to operate successfully in Permissionless and Permissioned blockchains contexts, and whether the protocol delivers atomic updates across blockchains.
