摘要

随着比特币的出现，作为比特币底层技术的区块链进入了人们的视野。近年来，区块链及其相关技术发展迅速。共识算法是区块链技术实现的关键。在区块链节点之间达成共识的过程中会出现拜占庭节点。在区块链中容忍拜占庭节点以达成共识。一致性是共识算法的基本性能。本文首先介绍了区块链技术及其共识算法在其中的应用;其次，介绍了经典的PBFT算法;然后，介绍了现有的一些共识算法;最后总结了共识算法的研究现状和面临的挑战，并对其前景进行了分析。

BFT Consensus Algorithms

With the advent of Bitcoin, the blockchain as the underlying technology of Bitcoin has entered people’s field of vision. In recent years, the blockchain and its related technologies have developed rapidly. The consensus algorithm is the key to the realization of blockchain technology. There will be Byzantine nodes in the process of reaching consensus among the nodes in the blockchain. Byzantine nodes are tolerated in the blockchain to achieve consensus. Consensus is an essential performance of consensus algorithms. This paper first introduces blockchain technology and the application of consensus algorithms in it; secondly, introduces the classic PBFT algorithm; then, introduces some existing consensus algorithms; finally summarizes the research status and challenges of consensus algorithms, and analyzes its Prospects.

期刊介绍： The Journal of Cloud Computing: Advances, Systems and Applications (JoCCASA) will publish research articles on all aspects of Cloud Computing. Principally, articles will address topics that are core to Cloud Computing, focusing on the Cloud applications, the Cloud systems, and the advances that will lead to the Clouds of the future. Comprehensive review and survey articles that offer up new insights, and lay the foundations for further exploratory and experimental work, are also relevant.
