Abstract

Blockchain technology is increasingly popular and has been widely applied in many industrial fields, due to its unique properties of decentralization, immutability, and traceability. Blockchain systems in different fields vary, with different block structures, consensus mechanisms and access permission models. These differences make it hard for different blockchain systems to interoperate with each other, which isolates them. Cross-chain technologies have been developed to solve this isolation problem in order to improve the interoperability of blockchains. Although some surveys on cross-chain technologies can be found, they are unable to keep up with the latest research progress due to their extremely fast pace of development. Moreover, the literature misses general criteria to evaluate the quality of cross-chain technologies. In this paper, a comprehensive literature review of cross-chain technologies is conducted by employing a comprehensive set of evaluation criteria. The preliminaries on blockchain interoperability are first presented. Then, a set of evaluation criteria is proposed in terms of security, privacy, performance, and functionality. The latest cutting-edge works are reviewed based on the proposed taxonomy of cross-chain technologies and their performance is evaluated against our proposed criteria. Finally, some open issues and future directions of cross-chain research are pointed out.

区块链互操作技术综述

区块链技术由于其独特的去中心化、不变性、可追溯性等特性，越来越受到人们的欢迎，并在许多工业领域得到了广泛的应用。不同领域的区块链系统各不相同，具有不同的块结构、共识机制和访问权限模型。这些差异使得不同的区块链系统难以相互操作，从而使它们相互隔离。为了提高区块链的互操作性，开发了跨链技术来解决这种隔离问题。虽然可以找到一些关于跨链技术的调查，但由于其发展速度非常快，无法跟上最新的研究进展。此外，文献缺乏评估跨链技术质量的一般标准。本文采用一套综合的评价标准，对交叉链技术进行了全面的文献综述。首先介绍了区块链互操作性的初步研究。然后，从安全性、隐私性、性能和功能方面提出了一套评估标准。根据交叉链技术的分类，对最新的前沿工作进行了回顾，并根据我们提出的标准对其性能进行了评估。最后，指出了交叉链研究中存在的问题和未来的研究方向。
