Delegated proof of stake (DPoS) significantly reduces the time required for transaction verification by selecting representative nodes to generate blocks, and it has become a mainstream consensus algorithm. However, existing DPoS algorithms have issues such as \u201cone ballot, one vote\u201d, a low degree of decentralization, and nodes performing malicious actions. To address these problems, an improved DPoS algorithm based on community discovery is designed, called CD-DPoS. First, we introduce the PageRank algorithm to improve the voting mechanism, achieving \u201cone ballot, multiple votes\u201d, and we obtain the reputation value of each node. Second, we propose a node voting enthusiasm measurement method based on the GN algorithm. Finally, we design a comprehensive election mechanism combining node reputation values and voting enthusiasm to select secure and reliable accounting nodes. A node credit incentive mechanism is also designed to effectively motivate normal nodes and drive out malicious nodes. The experimental simulation results show that our proposed algorithm has better decentralization, malicious node eviction capabilities and higher throughput than similar methods.<\/jats:p>","DOI":"10.3390\/e25091320","type":"journal-article","created":{"date-parts":[[2023,9,11]],"date-time":"2023-09-11T08:58:08Z","timestamp":1694422688000},"page":"1320","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["Delegated Proof of Stake Consensus Mechanism Based on Community Discovery and Credit Incentive"],"prefix":"10.3390","volume":"25","author":[{"given":"Wangchun","family":"Li","sequence":"first","affiliation":[{"name":"School of Information Engineering, Jiangxi University of Science and Technology, Ganzhou 341000, China"}]},{"given":"Xiaohong","family":"Deng","sequence":"additional","affiliation":[{"name":"School of Electronics and Information Engineering, Gannan University of Science and Technology, Ganzhou 341000, China"},{"name":"Key Laboratory of Cloud Computing and Big Data, Ganzhou 341000, China"}]},{"given":"Juan","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Information Engineering, Jiangxi University of Science and Technology, Ganzhou 341000, China"}]},{"given":"Zhiwei","family":"Yu","sequence":"additional","affiliation":[{"name":"School of Information Engineering, Jiangxi University of Science and Technology, Ganzhou 341000, China"}]},{"given":"Xiaoping","family":"Lou","sequence":"additional","affiliation":[{"name":"College of Information Science and Engineering, Hunan Normal University, Changsha 410081, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,9,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Vangipuram, S.L.T., Mohanty, S.P., Kougianos, E., and Ray, C.
