評(píng)《區(qū)塊鏈共識(shí)機(jī)制研究綜述》

區(qū)塊鏈?zhǔn)钱?dāng)前的研究熱點(diǎn)，作為區(qū)塊鏈核心技術(shù)之一的共識(shí)機(jī)制，更是受到研究人員和業(yè)界人士的廣泛關(guān)注。《密碼學(xué)報(bào)》2019年刊登的文章《區(qū)塊鏈共識(shí)機(jī)制研究綜述》較為深入、系統(tǒng)、全面地總結(jié)了現(xiàn)有的區(qū)塊鏈共識(shí)機(jī)制。文章從系統(tǒng)模型、共識(shí)本質(zhì)、激勵(lì)模式和安全風(fēng)險(xiǎn)等多個(gè)角度，將共識(shí)機(jī)制分為經(jīng)典分布式共識(shí)和區(qū)塊鏈共識(shí)兩大類，并對(duì)后者中的非授權(quán)共識(shí)又做了進(jìn)一步細(xì)分和梳理。文章通過豐富的數(shù)據(jù)和圖例信息，詳細(xì)介紹每一類共識(shí)機(jī)制的基本流程，深入探究典型方案，綜合分析優(yōu)缺點(diǎn)、實(shí)現(xiàn)性能和安全性。文章結(jié)構(gòu)清晰、論述詳實(shí)、文獻(xiàn)引用全面，是關(guān)于共識(shí)機(jī)制的一篇優(yōu)秀綜述文章，對(duì)從事區(qū)塊鏈技術(shù)研究的學(xué)者和技術(shù)人員, 具有很好的借鑒和參考價(jià)值。

Review on “Overview on Blockchain Consensus Mechanisms”

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“Overview 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. Through rich data and legend information, the article introduces the basic process of each type of consensus mechanism in detail, delves into typical solutions, comprehensively analyzes the advantages and disadvantages, achieved performance and security. The structure of the article is clear, the discussion is concise, and the literature citation is comprehensive. It is an excellent review about consensus mechanisms, which has a high reference value for scholars and technical personnel engaged in the research of Blockchain technology.
