论文摘要
在Bitcion的白皮书中，Nakamoto描述了一个比特币系统，该系统可以在没有第三方组织的情况下实现点对点的在线付款。在支持这种神奇的应用程序方面并颠覆了传统的集中式系统之后，区块链技术引起了全球关注，引发了研究的研究兴起，大量的区块链共识算法，并产生了大量创新应用。尽管各种共识算法继续随着区块链产品和应用的迭代而继续发展，但工作证明（POW）和Skake（POS）算法仍然是共识算法的核心。本文讨论了区块链共识机制中的两种POW和POS算法，并分析了两种共识机制的优点和现有问题。由于共识机制是区块链技术的主要重点，并且具有许多影响因素，因此本文讨论了当前的问题和一些改进的想法，并选择了一些典型的算法以进行更系统的介绍。此外，还讨论了一些与安全和绩效有关的重要问题。本文为研究人员提供了有关区块链共识机制的很好的参考。
In the white book of Bitcion, Satoshi Nakamoto described a bitcoin system that can realize point-to-point online payment without a third-party organization. After supporting this magical application scenario and subverting the traditional centralized system, the blockchain technology has attracted worldwide attention, triggered a research upsurge of blockchain consensus algorithm, and produced a large number of innovative applications. Although various consensus algorithms continue to evolve with the iteration of blockchain products and applications, Proof of Work (POW) and Proof of Skake (POS) algorithms are still the core of consensus algorithms. This paper discusses two algorithms of POW and POS in blockchain consensus mechanism, and analyzes the advantages and the existing problems of the two consensus mechanisms. Since consensus mechanism is the main focus of blockchain technology and has many influencing factors, this paper discusses the current problems and some improved ideas, and selects some typical algorithms for a more systematic introduction. In addition, some important issues related to safety and performance are also discussed. This paper provides the researchers a great reference on blockchain consensus mechanism.
