After all, the resources required to investigate even 20% of users would likely exceed those available to law enforcement. Additionally, we find that topic engagement is the best measure for predicting vendors, regardless of their level of success. Darknet markets, or cryptomarkets, are online marketplaces that operate on anonymity networks like Tor or I2P and use cryptocurrencies for transactions — typically involving illegal or gray-market goods and services. The best darknet markets in 2025 prioritize user-friendly interfaces, making drug shopping as seamless as conventional e-commerce. Platforms like Nexus and Abacus feature intuitive layouts with search filters, product categories, and real-time chat support.
For bidirectional harmonic closeness centrality, the shortest paths can be determined following edges regardless of their direction. However, for incoming and outgoing harmonic closeness centrality the paths may follow edges only in one direction, either following the direction of the edges (outgoing) or going against the direction of the edges (incoming). The weighted variants of these measures use the inverse of the edge weights during shortest distance computation, such that stronger connections equate to shorter distances. One of the central76 discussion forums was Reddit’s /r/DarkNetMarkets/,777879 which has been the subject of legal investigation, as well as the Tor-based discussion forum, The Hub. Cryptomarkets emerged in 2011 with the launch of Silk Road on the Tor network.
Where To Find Darknet Market Links
The platform enabled users to hire sophisticated hackers to target victims and gain access to their private information and take over online accounts. 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. The most common and convenient way to access the dark web is to download & install the Tor browser.
These platforms prioritize user anonymity through decentralized networks, reducing reliance on centralized servers vulnerable to attacks. Transactions are streamlined using Monero and Zcash, offering stronger privacy than Bitcoin. Darknet markets in 2025 offer secure and efficient platforms for drug transactions, leveraging advanced encryption and decentralized networks. These platforms prioritize anonymity, using Tor and Bitcoin to mask user identities and financial trails.
Some respondents said that being protected from physical risk on the dark web is not only a benefit for existing drug suppliers, but may also make the activity attractive to people who would not otherwise be willing to sell drugs. Encryption technologies allow vendors to communicate with customers and receive payments anonymously. The drugs are delivered in the post, so vendor and customer never have to meet in person. The U2U network is formed by the entire set of interacting users (black and gray arrows with their respective users).
We start by investigating the number of new stable U2U pairs and their trading volume during the COVID-19 period. Users in stable pairs meeting both inside and outside DWMs have been growing over the last two years, since the shutdown of AlphaBay9, the largest DWM at the time. In 2020, a total of 6778 pairs of users in stable pairs met inside a DWM, corresponding to 192% of the 2019 level and to 255% of the 2018 level, see Fig. Pairs of users in stable pairs meeting inside a DWM traded for a total of $145 million in 2020, which corresponds to 252% of the 2019 level, and to 593% of the 2018 level, see Fig.

Analysing and understanding cryptomarkets is essential to become proactive in the fight against the illicit drug trade. This study analysed data that had previously been collected on cryptomarkets from December 2013 to March 2015. The results revealed the domestic nature of the virtual Australian illicit drug trade (i.e. Australian sellers essentially ship their products to local customers). Particularly, the virtual Australian illicit drug trade is dominated by amphetamine-type substances (ATS), mainly methamphetamine and 3,4-methylenedioxymethamphetamine (MDMA), and cannabis.

The absence of centralized control reduces shutdown risks, making Nexus and Abacus preferred choices for efficient, secure transactions. Sedatives (such as diazepam and alprazolam) and CNS stimulants (mainly Adderall, modafinil and methylphenidate) had the greatest share of sales, but usage and trends varied by location. The UK has high and rising levels of sedative sales, whilst the USA has the greatest stimulant sales and increasing sedative rates. Sales of drugs used in the treatment of opioid dependency are also substantial in the USA.

Although the number of multisellers suffers a severe drop (Fig. 4a) and the multiseller network drastically shrinks (Fig. 6), the net income of multisellers remains persistently the largest among sellers throughout the whole period of observation, as shown in Fig. This suggests that the multiseller activity is sensitive to external shocks but also that it yields higher profits. Throughout the whole period of observation, the dominant category of buyers is market-U2U buyers followed by market-only buyers, representing on average 52% and 42% of all buyers, respectively. The U2U-only category is comparatively small, representing only 6% of all buyers on average. The number of market-U2U and market-only buyers also drops as a consequence of operation Bayonet. However, compared to sellers, the drop is notably smaller, and the number of buyers rapidly recovers to previous values.
Data Availability
However, this information ecosphere has been hampered as DeepDotWeb was shut by police, and r/DarkNetMarkets was closed by Reddit. Cryptomarkets are Tor-connected services which allow the exchange of illicit goods and services. Most of them present as shopfronts where vendors sell an array of drugs. Buyers pay using a cryptocurrency, typically Bitcoin, and the drug is delivered to them through the postal or courier system. Lively discussion forums discuss the quality of the drugs sold and the professionalism of vendors, among other topics. The evolution of darknet markets in 2025 has introduced new cryptomarkets with enhanced security and efficiency.

All edges are weighted to indicate the strength of the social tie implied by the edge. Here, an exponentially decaying weighting function is intended to model the probability of the edge representing a direct response. In the Results section we shortly describe the dataset and measures used before reporting on our results. The results and their implications for law enforcement are discussed in the Discussion section. Finally, the “Methods” section provides more in-depth descriptions on the dataset and network extraction as well as the activity indicators, network measures, and evaluation metrics used in this work. We showed that a small fraction of traders is responsible for a large fraction of the trading volume, and by analysing the networks of buyers and sellers, we found different resilience regimes.
- There we show that the sales recall is generally between 10 and 20% higher than the corresponding vendor recall.
- During 2016 and 2017, the edges are polarized by AlphaBay, the dominant market (see Fig. 3).
- Then, we explore to what extent the rankings induced by (network) measures can reduce the set of users for law enforcement to investigate, while still including the greatest share of successful vendors.
- As such, a vendor with a high betweenness is more likely to have a larger pool of buyers as they may be able to draw from more relatively distinct communities of buyers.
- Therefore, the induced rankings have the potential to assist law enforcement by allowing them to focus investigative efforts on higher ranked users.
- These innovations allow for early confirmation of market changes such as the emergence of fentanyl and other novel synthetic opioids 10, 11 and of new drug delivery systems, such as e-cigarette/vaping methods for drug consumption 12.

We found that betweenness centrality was the only network measure that was able to detect a substantial set of successful vendors that were not found by any of the activity indicators. Thus, there are vendors that may not be the most active, start the most topics or get the most engagement on their topics, but that are able to establish themselves in the structure of the communication network such that they lie on many shortest paths. High betweenness vendors may, for example, be connecting buyers of distant locations and/or diverse goods. However, the question of why (certain) vendors achieve high betweenness scores, remains an open question to be addressed in future work through methods such as topic modelling. In short, while topic engagement showed the best overall performance, betweenness centrality could provide the greatest added value to law enforcement activities for reducing the set of users to investigate.

As such, the in-degree is similar to the activity indicators, but focused on the number of individuals engaging with the user rather than the volume of engagement. We report results for the unweighted in-degree, as we believe the number of neighbors, i.e., the number of potential customers, to be a better predictor of vendor success than the combined strength of the social ties to these neighbors. Weighted in-degree showed similar results, but with slightly fewer detected vendors that were not found by the activity indicators. Sales and post activity of recalled (in top 20%) and non-recalled (outside top 20%) users for topic engagement, betweenness centrality, and their intersection for September 2014, for current (a,b) and future success (c,d), respectively.

Key players include the administrators and moderators responsible for the existence and proper functioning of the cryptomarket. However, they also include the more successful vendors that are responsible for the majority of the trade conducted on the cryptomarket. Identifying which users function as administrators can often be as easy as looking at the titles assigned to them on the cryptomarkets’ forums. Similarly, if sales statistics were shared on the cryptomarket, currently successful vendors would be easily identifiable.
