This paper delves into the intersection of blockchain analytics and artificial intelligence (AI) to advance transaction analysis. The primary aim is to bolster fraud detection and enhance transaction efficiency. Through a comprehensive literature review, we identify gaps in existing knowledge and lay the groundwork for our research. We introduce a novel transaction\u2010hybrid model developed using machine learning (ML) algorithms, including support vector machines (SVMs),\n                    <jats:italic>K<\/jats:italic>\n                    \u2010nearest neighbors (KNNs), and random forest (RF). This transact\u2010hybrid model aims to fortify fraud detection capabilities by harnessing the strengths of each algorithm. We curate a unique dataset comprising 1000 instances, incorporating critical transaction features such as transaction hash, block number, transaction fee and gas limit, with binary classification indicating fraudulent transactions. Meticulous preprocessing, including feature engineering and data splitting for training and testing, is conducted. Visualization techniques, including seaborn\u2010based graphs, correlation plots and violin plots, elucidate the dataset\u2019s characteristics. Additionally, a spring colormap correlation map enhances the understanding of feature relationships. Transaction fee distributions before and after preprocessing are visually presented, highlighting the impact of data preparation. We introduce the novel transact\u2010hybrid classifier (THC) with detailed mathematical equations, emphasising its contribution to transactional fraud detection. The classifier integrates SVM, KNN and RF outputs using an exclusive OR operation, showcasing innovation in model development. To evaluate model performance, we conduct a comparative analysis, incorporating SVM, KNN, RF and a voting classifier. Bar plots for accuracy, precision, recall and F1 score, with a custom plasma colormap, offer a visual summary of each model\u2019s metrics. Furthermore, a receiver operating characteristics (ROC) curve analysis is presented, highlighting the area under the curve (AUC) for SVM, KNN, RF and voting models, providing a comprehensive view of their performance in distinguishing between true positive and false positive rates. Our proposed method demonstrates over 99% efficacy in fraud detection, underscoring its potential impact in transaction analysis.\n                  <\/jats:p>","DOI":"10.1049\/ise2\/5560771","type":"journal-article","created":{"date-parts":[[2025,9,5]],"date-time":"2025-09-05T11:35:30Z","timestamp":1757072130000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Blockchain Analytics Based on Artificial Intelligence: Using Machine Learning for Improved Transaction Analysis"],"prefix":"10.1049","volume":"2025","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1451-9359","authenticated-orcid":false,"given":"Ahmed I.","family":"Alutaibi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"265","published-online":{"date-parts":[[2025,9,5]]},"reference":[{"key":"e_1_2_10_1_2","volume-title":"Blockchain Data Analytics","author":"Matthew D.","year":"2018"},{"key":"e_1_2_10_2_2","doi-asserted-by":"publisher","DOI":"10.3390\/joitmc7030189"},{"key":"e_1_2_10_3_2","doi-asserted-by":"publisher","DOI":"10.1155\/2021\/6126247"},{"key":"e_1_2_10_4_2","doi-asserted-by":"publisher","DOI":"10.1007\/s10479-020-03620-w"},{"key":"e_1_2_10_5_2","doi-asserted-by":"publisher","DOI":"10.3390\/app122412948"},{"key":"e_1_2_10_6_2","first-page":"568","article-title":"Artificial Intelligence and Blockchain in Audit and Accounting: Literature Review","volume":"16","author":"Zem\u00e1nkov\u00e1 A.","year":"2019","journal-title":"Wseas Transactions on Business and Economics"},{"key":"e_1_2_10_7_2","doi-asserted-by":"publisher","DOI":"10.1109\/ACCESS.2018.2890507"},{"key":"e_1_2_10_8_2","doi-asserted-by":"publisher","DOI":"10.1147\/JRD.2019.2900638"},{"key":"e_1_2_10_9_2","doi-asserted-by":"publisher","DOI":"10.24840\/2183-0606_011.003_0003"},{"key":"e_1_2_10_10_2","doi-asserted-by":"publisher","DOI":"10.3389\/fbloc.2022.927006"},{"key":"e_1_2_10_11_2","unstructured":"HamzaM.
