Furthermore, the weighted degree variants sum the weights of the connections with the neighbors. Law enforcement and security researchers recommend treating all darknet interactions as compromised by default.
Network Extraction
For directed betweenness centrality, paths must follow the direction of the edges, while undirected betweenness can follow edges in either direction. Like for harmonic closeness centrality, the weighted variants use the inverse of the edge weights during shortest path computation, such that stronger connections equate to shorter distances. As direction and weighting can have a large impact on the probability of lying on a shortest path, we use the directed weighted betweenness in this study. We note that where the interpretation of paths was unclear for harmonic closeness centrality, this is less of an issue for betweenness centrality. After all, for betweenness centrality we rely on the fact that the user exists on many shortest paths, and is less reliant on its specific position in the path. When viewed on the scale of the whole network, existing on many shortest paths implies being a central figure in the various conversations occurring on the forum, regardless of whether the individual paths relate to the same conversation.
As input parameter, we considered the full network, transactions from/to DWMs and U2U transactions between users (see Section S4). Plotted lines indicate the median value while bands represent the 95% confidence interval. Negative and positive numbers indicate the days prior and after the closure, respectively. Only the 33 DWMs that closed during our time period are considered in the analysis. (a) Schematic representation of an ego network surrounding a dark web marketplace (“DWM”, in red).

But more importantly, analyzing the forum data over time, we find evidence that attaining a high betweenness score comes before vendor success. This suggests that the proposed network-driven approach of modelling user communication might prove useful as an early warning signal for key player identification. Despite achieving the best vendor recall, topic engagement is only able to detect up to 2/3rd of the most successful vendors for current success and even fewer for future success.
Innovations like multisig escrow and auto-encrypted messaging further optimize safety and convenience. Darknet markets in 2025 prioritize accessibility and security, making drug shopping safer than ever. The first step is locating verified onion links through updated darknet market lists.
Top Dark Web Markets List: History, Evolution, And Current Landscape (
In the vertical axis, markets are in the chronological order of their launch date, although for some markets the activity effectively starts after the launch date (e.g., AlphaBay). Buyers simultaneously active on multiple markets also play the role of connectors in the ecosystem. Therefore, we analyse the temporal network where nodes are the active markets and an edge between the nodes represents the number of multibuyers between them, what we henceforth call the multibuyer network. The structural change seen in the multiseller network is not observed in the multibuyer network, as show in Fig. The evolution of the multibuyer network follows a similar pattern to the multiseller network until 2015, despite a stronger polarization around Hydra instead of AlphaBay during 2017.

Cryptomarkets may define PWUD as consumers and contribute to reshaping their identities around principles of self-directed, informed consumption. This structured approach minimizes scams, creating a streamlined experience for secure transactions.
Data And Methods
Therefore, although larger in number, U2U-only sellers typically make the smallest income. This suggests that sellers with more diverse sources of income, such as multisellers and market-U2U sellers, are able to produce a higher income. Additionally, we observe that, except for U2U-only sellers, the median income of the other types of sellers drops after the major shock caused by operation Bayonet (see Supplementary Information Section S4). The most affected are multisellers, with a drop of 78% in the median income, followed by market-U2U and market-only sellers, with a drop of 59% and 47%, respectively. Although these three types of sellers are significantly affected, they recover and surpass the median income value they had before Bayonet (see Fig. 4c; Supplementary Information Section S4).
How Decentralized Networks Make Drug Trade Safer On The Darknet
On the contrary, for future success the final months show lower difference scores than before. This behaviour is likely due to the delay between successful vendors establishing themselves in the network and reaping the benefits in terms of sales. In other words, high betweenness centrality is expected to be more a prelude to than a consequence of vendor success. Thus, these results show the potential of betweenness centrality as an early warning signal for future vendor success. Existing research studying the workings of cryptomarkets and aimed at assisting law enforcement in identifying key players, often uses methods such as topic modelling or sentiment analysis7,8,9,10,11,12.
How Darknet Markets And Fraud Shops Fought For Users In The Wake Of Hydra’s Collapse
- TRM research shows that darknet markets (DNMs) have bounced back following the shutdown of Hydra, the world’s largest such marketplace, by German law enforcement in April 2022.
- Notably, the number of multisellers suffers the largest drop of \(-99\%\) by the end of the first quarter of 2018.
- For a vendor, this in turn might imply that they or their products are often discussed and that the vendor actively engages with their clientele, all of which may promote their sales.
- Sales of drugs such as antidepressants, antipsychotics, mood stabilisers and antidementia drugs – all drugs with limited abuse potential – were negligible, indicating minimal levels of online cryptomarket procurement for self-medicating mental health problems.
- Nevertheless, due to their unregulated nature, DWMs exhibit behaviours not observed in regulated marketplaces.
One impact is to foreground each drug being sold as a specific branded consumer product with pharmacological attributes that can be closely assayed. This process thus draws on and brings together people’s cumulative experiential and subcultural knowledge, in common with other online drug-focused forums that discuss not just the quality of each drug, but what the drug is to them as a categorical object 36. Easier availability may reduce temptations to hoard 37, but tendencies towards vendors selling solely or at discounted rates in larger quantities may counteract that. The benefits of making large purchases means that purchases are often made with the intent of social supply 38. Some cryptomarket users exhibit more isolated use patterns such as using MDMA/Ecstasy, cocaine and LSD alone 39.
Additionally, we analyse the U2U network of transactions, i.e., the transactions between pairs of market first-neighbors where the source and destination nodes are market users without the market as an intermediate. In the U2U network, an edge connects nodes that are not necessarily users of the same market. Previous studies have shown that, although the number of users and transactions is larger in markets, the trading volume in the U2U network is larger than that of markets13.
- In the previous section we determined that betweenness centrality and topic engagement are the measures with the greatest vendor recall performance.
- Bitcoin is often used on darknet markets as a means of payment, as it is difficult to trace and can be exchanged for other currencies without revealing the user’s identity.
- India, China and Canada have been carried forward in this work for theoretical reasons rather than their market size, and all three paint an interesting picture that suggests they are at least source countries, particularly of sedatives.
- That may serve to reduce some of the collateral harms of the illicit drug market 48 while at the same time concentrating risk and systemic violence among an already marginalised segment of the drug-using population that has little access to drug-delivery methods.
- Note that we found this variant of PageRank to indeed have the best performance.
- For the weighted and directed variant, i.e., links representing responding to one another, the interpretation of paths (and their lengths) that start or end at a specific user are unclear as the path may not represent a single ‘conversation’.
Law enforcement agencies, however, have only recently started targeting individual sellers. The first operation took place in 2018 and successfully led to the arrest of 35 sellers41, while the largest operation to date occurred in 2020 and led to 179 arrests in six different countries42. Our study indicates that a much higher number of highly active DWM users, on the order of tens of thousands, is involved in transactions with other DWM users. Moreover, our analysis paves the way to a deeper understanding of U2U transactions in online marketplaces.
Pwnbox Is A Great Way To Use Tor
There is evidence of a move towards the more potent sedative alprazolam – already implicated as a source of problematic NMPDU in the USA – in Australia and the UK. Sales of drugs such as antidepressants, antipsychotics, mood stabilisers and antidementia drugs – all drugs with limited abuse potential – were negligible, indicating minimal levels of online cryptomarket procurement for self-medicating mental health problems. In Grand Theft Auto Online, players who purchase warehouses and garages for illicit cargo and stolen cars can buy/steal and sell them through trade on the “SecuroServ” syndicate website. After the Biker DLC, players can now purchase buildings for illegal drugs and counterfeit products manufacture, and distribute them through a darknet website called “The Open Road” where law enforcement cannot be notified of the player’s trade. The largest component of the S2S network one year before and one year after the operation Bayonet. Nodes are sellers that are active within the time period, and an edge is placed between two sellers if at least one transaction occurs between them during the period.
Vendor Shops Replacing Big Markets
Here, we set out to find the main actors in the DWM ecosystem and assess their systemic impact on a dataset of 40 million Bitcoin transactions involving the 31 major markets in the period 2011–2021. Importantly, the algorithm returns reasonable estimates for the number of sellers when compared against a benchmark of nine DWMs where estimates exist. Then, we reveal a concentration of activity around an elite group of participants, where a large fraction of the trading volume is driven by a small number of players. Specifically, we uncover distinct types of buyers and sellers based on their activity between markets and the U2U network, and detect a shift in the ecosystem’s activity towards the U2U network after a major external shock in the markets. We find that trading properties of buyers and sellers reflect the dominance of DWMs in the ecosystem.
The weighted variant also takes into account how strong the relation to these users is. Thus, a high in-degree in our networks indicates many different users responding within a relatively short time frame or responding in a topic they started. Since it is likely that those that respond shortly after a post have seen that post, a high in-degree implies visibility to many different users, thereby improving the aforementioned brand awareness. As brand awareness promotes trust and sales22,23 and trust is a good predictor of vendor selection24, a high in-degree might serve as a good predictor of vendor success. The horizontal bars represent each market lifetime, i.e., the time when the market becomes active until its closure, and is colored according to the market’s monthly trading volume in USD.
