“…We rely on the principle of tainted flows to trace the coins from source actors. Taint analysis has been used most notably in the context of tracking money from illegal sources [1,3,8,24,32]. However, those works mainly focus on the destination of tainted coins.…”

“…Output: edges is the edge list of the payout flow. Our algorithm applies haircut tainting, which assumes that the tainted money is divided equally to all output transactions in proportion to their amount [1,32].…”

“…We subsequently apply whole graph embedding methods to automatically assign taint networks to their origin actor. Beyond the demonstration that each actor has a characteristic flow allowing us to recognize its position in the network [1,22,32], our method can also be helpful for actor tracking as well as actor deanonymization tasks. The embedding of money flows from different actors is a promising feature for downstream tasks in machine learning models to classify the role of actors [15,38] or predict illegal transaction activities in the Bitcoin blockchain [35].…”

Bitcoin is the first and highest valued cryptocurrency that stores transactions in a publicly distributed ledger called the blockchain. Understanding the activity and behavior of Bitcoin actors is a crucial research topic as they are pseudonymous in the transaction network. In this article, we propose a method based on taint analysis to extract taint flows-dynamic networks representing the sequence of Bitcoins transferred from an initial source to other actors until dissolution. Then, we apply graph embedding methods to characterize taint flows. We evaluate our embedding method with taint flows from top mining pools and show that it can classify mining pools with high accuracy. We also found that taint flows from the same period show high similarity. Our work proves that tracing the money flows can be a promising approach to classifying source actors and characterizing different money flow patterns.

“…By providing a fresh address for each donor, the website grants them a certain level of privacy, as the newly-generated receiving address is not overtly linked to the entity it belongs to [16]. However, despite the simplicity of generating new addresses, studies show that the majority of Bitcoin users repeatedly reuse the same address, which suggests that the majority of Bitcoin users do not place a high value on anonymity [4].…”

Dark-web sites like the (now defunct) Silk Road advertised anything from drugs to assassinations in exchange for this new currency [4].

Bitcoin remains the most widely used cryptocurrency. It has attracted users from tech enthusiasts to commercial investors to criminals, in no small part due to its reputation for anonymity. While not designed primarily for privacy, Bitcoin's architecture contains several provisions that can be exploited by criminals to conduct illegal activity including money laundering and collecting payments from ransomware and scams. Since Bitcoin's creation in 2008, various groups such as law enforcement, lawyers, criminals and privacy-focused Bitcoin users have been locked in a struggle between attempts to reveal hidden Bitcoin users' identities and attempts to keep those identities concealed. We present a survey of the techniques used within Bitcoin to reveal or conceal users' identities. We provide an easy to understand explanations of how these techniques work and provide a cross reference of which revealing techniques are effective for specific concealing techniques.
