共识协议综述

Survey of Consensus Protocols

Abdul Wahab, Waqas Mehmood

摘要:

自2008年基于工作量证明(PoW)的比特币出现以来,分布式账本技术得到了广泛的普及和采用。它是一个分布式、透明和不可变的数据库,记录了参与者之间共享和执行的所有事务或事件。所有交易都由网络中的多个节点通过分布式加密机制(共识协议)进行验证和维护,而无需中央权威机构。它形成了这项技术的核心,不仅验证了附加到分类账的信息,而且还确保了它在所有节点上的附加顺序。这是其安全、问责和信任的基础。虽然许多研究人员正在努力改进当前的协议,使其具有量子抵抗性,容错性和节能性。其他人则专注于开发最适合特定用例的协议的不同变体。在本文中,我们将回顾分布式账本技术的不同共识协议及其实现。我们还将回顾它们的性质,概念和类似的工作,然后进行简要的分析。

英文摘要:

Distributed ledger technology has gained wide popularity and adoption since the emergence of bitcoin in 2008 which is based on proof of work (PoW). It is a distributed, transparent and immutable database of records of all the transactions or events that have been shared and executed among the participants. All the transactions are verified and maintained by multiple nodes across a network without a central authority through a distributed cryptographic mechanism, a consensus protocol. It forms the core of this technology that not only validates the information appended to the ledger but also ensures the order in which it is appended across all the nodes. It is the foundation of its security, accountability and trust. While many researchers are working on improving the current protocol to be quantum resistant, fault-tolerant, and energy-efficient. Others are focused on developing different variants of the protocol, best suited for specific use cases. In this paper, we shall review different consensus protocols of distributed ledger technologies and their implementations. We shall also review their properties, concept and similar-work followed by a brief analysis.
