分布式账本技术的发展历程研究综述

物联网、人工智能、大数据等众多领域缺乏量身定制的安全隐私技术保障，基于分布式账本技术(DLT)的系统作为一种分散的数据管理方法可以很好地满足其安全需求，因此基于分布式账本技术的系统层出不穷。为了帮助后续的研究者更全面快速地了解分布式账本技术，梳理了近年来基于分布式账本的研究成果，分别从数据结构、技术原理、共识机制和性能等多个角度对区块链进行深入分析，并且基于当前研究现状详细比较分析了分布式账本技术的一些最新进展，如哈希图(Hashgraph)、全链(Holochain)和初链(Truechain)等。最后总结了该领域未来的发展前景。

Review on development history of distributed ledger technology

Due to the lack of security and privacy technology guarantee of volume voice customization in many fields such as Internet of Things, artificial intelligence and big data, the system based on distributed ledger technology(DLT) can well meet the security requirements as a decentralized data management method. Consequently, systems based on distributed ledger technology emerge in an endless stream. In order to help subsequent researchers understand the field of distributed ledger technology more comprehensively and quickly, this paper reviewed the research results based on distributed ledger technology in recent years. It analyzed the blockchain in depth from the perspectives of data structure, technical principle, consensus mechanism and performance, and compared and analyzed some recent advances in distributed ledger technology in detail based on the current research status, such as Hashgraph, Holochain and Truechain. Finally, the future development prospect of this field was summarized.
