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.
