This method first designs a credit-rating mechanism that meets industry characteristics based on business needs. Second, it proposes a user credit evaluation model based on the blockchain architecture. Finally, the improved Softmax regression algorithm is used to train the proposed credit evaluation model, which effectively solves the credit rating. The multiclassification problem has achieved the goal of categorizing the credit rating of the enterprise. The simulation results show that the credit evaluation mechanism proposed in this paper can accurately evaluate the multisource credit data that lacks trust foundation and effectively realize the credit rating of power grid material supply chain enterprises. The credit evaluation mechanism proposed for Power IoT in this paper could have high potential for entity identity authentication and rating for securing mobile video communications.<\/jats:p>","DOI":"10.1155\/2022\/3842077","type":"journal-article","created":{"date-parts":[[2022,2,15]],"date-time":"2022-02-15T01:05:50Z","timestamp":1644887150000},"page":"1-12","source":"Crossref","is-referenced-by-count":2,"title":["An Effective Credit Evaluation Mechanism with Softmax Regression and Blockchain in Power IoT"],"prefix":"10.1155","volume":"2022","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4977-1589","authenticated-orcid":true,"given":"Da","family":"Li","sequence":"first","affiliation":[{"name":"Department of Science and Research, State Grid Blockchain Technology (Beijing) Co., Ltd.,, Beijing, 100053, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dong","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Digital Technology, State Grid Electronic Commerce Co., Ltd.,, Beijing, 100053, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei","family":"Jiang","sequence":"additional","affiliation":[{"name":"Department of Internet, State Grid Corporation of China, Beijing, 100031, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4265-3280","authenticated-orcid":true,"given":"Qinglei","family":"Guo","sequence":"additional","affiliation":[{"name":"State Grid Blockchain Laboratory, State Grid Corporation of China, Beijing, 100053, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Desheng","family":"Bai","sequence":"additional","affiliation":[{"name":"Department of Digital Technology, State Grid Electronic Commerce Co., Ltd.,, Beijing, 100053, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei","family":"Shi","sequence":"additional","affiliation":[{"name":"Department of Science and Technology, State Grid Changzhou Power Supply Company, Changzhou, Jiangshu, 213004, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8255-6472","authenticated-orcid":true,"given":"Linna","family":"Ruan","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Networking and Switching Technology, Beijing University of Posts and Telecommunications, Beijing 100876, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.5755\/j01.ee.22.2.309"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1109\/TWC.2021.3093722"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1109\/MCOM.001.1900716"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1109\/jiot.2019.2905743"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1007\/s11749-020-00723-1"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1080\/14697688.2017.1383627"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.22059\/JTE.2017.63696"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1109\/ECIT50008.2020.00043"},{"key":"9","article-title":"Kirti: a blockchain-based credit recommender system for financial institutions","author":"S.
