评《区块链共识机制研究综述》

Review on “Overview on Blockchain Consensus Mechanisms”

区块链是当前的研究热点,作为区块链核心技术之一的共识机制,更是受到研究人员和业界人士的广泛关注。《密码学报》2019年刊登的文章《区块链共识机制研究综述》较为深入、系统、全面地总结了现有的区块链共识机制。文章从系统模型、共识本质、激励模式和安全风险等多个角度,将共识机制分为经典分布式共识和区块链共识两大类,并对后者中的非授权共识又做了进一步细分和梳理。

Blockchain is the current research hotspot.As one of the core Blockchain technologies,consensus mechanism is even widely concerned by researchers and industry professionals.The article“Overv iew on Blockchain Consensus Mechanisms”,published in Journal of Cryptologic Research in August 2019,summarizes the existing Blockchain consensus mechanisms in an in-depth,systematic,and comprehensive manner.From the perspective of system model,consensus essence,incentive mode,and security risk,the article systematically identifies the consensus mechanism into two categories:classic distributed consensus and Blockchain consensus,and for the unauthorized consensus of the latter,a detailed summary and specific research are carried out especially.
