Research Coin Mixing Detection It has been revealed in previous studies that Bitcoin's anonymity is not absolute. Coin mixing protocols have been proposed to address these anonymity issues by breaking or obfuscating the relationship between transaction inputs and outputs, thereby ensuring privacy. Due to their ability to enhance anonymity, these protocols are often associated with illegal money laundering activities, and some mixing services have faced sanctions. In order to prevent these illegal activities, a technology to detect coin mixing is needed. Currently, various detection technologies such as heuristic-based and machine learning-based are being studied, and the goal is to achieve the state-of-art among various studies. April 14, 2025
