The work proposes a machine-learning framework that assigns a Bitcoin address to predefined entity classes or to a specific company. Five coarse-grained classes are defined and 180 companies are targeted for fine-grained identification. Contributions include a 3M-address labeled dataset with engineered feature vectors, comparative experiments across techniques, and two classifier families (boosted trees and neural deep learning). Results report strong F1 performance and company linking accuracy.","Transaction Graph Analysis for Bitcoin Address Classification: Traditional Supervised Machine Learning and Deep Learning Methods  \nSeyedarash Saeidimanesh  \nA Thesis  \nIn the Concordia Institute for Information Systems Engineering  \nPresented in Partial Fulfillment of the Requirements  \nFor the Degree of  \nMaster of Applied Science (Information Systems Security) at Concordia University  \nMontral, Qubec, Canada  \nMarch 2024  \n© Seyedarash Saeidimanesh, 2024  \nCONCORDIA UNIVERSITY  \nSchool of Graduate Studies  \nThis is to certify that the thesis prepared  \nBy: Seyedarash Saeidimanesh  \nEntitled: Transaction Graph Analysis for Bitcoin Address Classification: Tradi  \ntional Supervised Machine Learning and Deep Learning Methods  \nand submitted in partial fulfillment of the requirements for the degree of  \nMaster of Applied Science (Information Systems Security)  \ncomplies with the regulations of this University and meets the accepted standards with respect to originality and quality.  \nSigned by the Final Examining Committee:  \n  Chair  \nDr. A.

We build a machine learning-based classification framework which is able to attribute a Bitcoin address to one of the predefined classes or to a specific company. We consider five distinct classes for coarse-grained classification: cryptocurrency exchanges, online marketplaces, mining pools, fundraising/charity platforms, and gambling; and 180 companies for fine-grained classification. Classes and the companies were selected so that they represent a broad spectrum of entities and activities within the Bitcoin ecosystem.  \nThis thesis has three main contributions. First, due to the lack of publicly available datasets suitable for testing machine-learning classification algorithms, we create our own labeled dataset consisting of 3M Bitcoin addresses (from 2016-2022), with each Bitcoin address assigned a readyto-use vector of carefully crafted features. Second, using this dataset, we conduct a comparative analysis of different machine-learning techniques and features for classification. Finally, we develop two types ofclassifiers: based on the Boosted tree algorithm and the neural network-based classifier. Both are able to attribute a Bitcoin address to one of the predefined classes/companies.  \nOur binary classification model achieves an F1 score of 76% using the Boosted tree algorithm, while our deep learning model achieves a 90% F1 score for multi-class classification with an accuracy of 92% and 28% higher than related work correspondingly. We achieve 67% accuracy for linking Bitcoin addresses to one of the 180 companies with our deep-learning model.  \nAcknowledgments  \nI am profoundly honored to express my heartfelt appreciation to my distinguished supervisor, Dr. Ivan Pustogarov, for his unwavering and invaluable support that has been instrumental in the successful completion of my master’s degree.
