Mixing services run on blockchain trading systems, enhancing the transaction privacy of blockchain users. Yet, in recent years, the mixing services provide fertile ground for concealing illicit fund flows. Therefore, security experts make great efforts to find an effective de-anonymization of mixing services. Unfortunately, current de-anonymization technologies are constrained by a fundamental issue, i.e., the lack of a comprehensive, extensive, and reliably labeled benchmark dataset. To address this problem, we propose a new method for acquiring mixing transaction data. We design and implement a method named TGweaver, which actively executes the complete mixing workflow within a simulated blockchain environment. Furthermore, to enhance the realism of the dataset, we introduce a ''behavioral fingerprint'' mapping strategy. Ultimately, the proposed dataset includes over 891K transactions, scaling existing benchmark sizes by 2 to 4 orders of magnitude. In experiments, we use the proposed data to systematically evaluate existing de-anonymization techniques. Experimental results reveal that the current mixing address linking methods, based on heuristic rules, lacks generalization capability in complex scenarios, exhibiting low precision. In contrast, the methods utilizing supervised learning demonstrate significant advantages.
