摘要

共识协议是实现分布式系统整体网络可靠性的关键算法。区块链作为分布式系统的代表，运用其特有的共识算法来保证系统的安全性和一致性。目前区块链系统中的三种主要共识算法是工作量证明(PoW)，权益证明(PoS)和委托权益证明(DPoS)。共识算法的发展过程说明了共识协议在区块链中的发展趋势。本文分析了三个代表性共识协议的发展:PoW, PoS和DPoS。然后比较了它们的优缺点，并讨论了共识协议的未来发展方向。

Development in Consensus Protocols: From PoW to PoS to DPoS

Consensus protocols are the essential algorithms to achieve overall network reliability in the distributed system. As the representative of the distributed system, the blockchain applies its specific consensus algorithm to ensure security and consistency in the system. The three main consensus algorithms in the blockchain system now are Proof of Work (PoW), Proof of Stake (PoS), and Delegated Proof of Stake (DPoS). The development process of consensus algorithms illustrates the trend of consensus protocols in the blockchain. This paper analyzes the development of three representative consensus protocols: PoW, PoS, and DPoS. Then we compare the advantages and disadvantages of them and discusses the future direction of consensus protocols.
