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. 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.
- More surprisingly, the UK represents 31% of the hypnotics & anxiolytics market, despite having a much smaller population than the USA.
- By routing traffic through multiple nodes, Tor ensures that IP addresses are concealed, reducing the risk of exposure.
- Therefore, we are likely better served by relying on the link representation of familiarity directly, i.e., using the undirected and unweighted variant.
- These platforms leverage advanced encryption technologies and decentralized systems to ensure that transactions remain confidential and untraceable.
- However, information regarding the origin and type of these novel synthetic opioids are needed to characterize cryptomarket data related to specific types of novel synthetic opioids, such as specific types of fentanyl analogs and other novel synthetic opioids.
The Role Of Law Enforcement In The Regulation Of Cryptomarkets (and The Limited Role Of Deterrence)
Along with the dataset, we also utilise the communication network extraction method proposed in Boekhout et al.27. This extraction method creates nodes for all active users and adds an edge connecting nodes for any posts by a pair of users that are in the same topic and adhere to certain parameters. The direction of these edges are from the user who placed the later post to the user who placed the earlier post. Additionally, edges are formed from every user who placed a post in a topic to the user who placed the first post in the topic. Here, an exponentially decaying weighting function is intended to model the probability of the edge representing a direct response. Figure 5 shows the total and monthly post activity and number of active users and vendors.
Keep Up With Developments In Drug Science
The composition of the Australian darknet drugs trade mirrors some aspects of the conventional illicit drugs trade. For example, cannabis was the most popularly traded drug by domestic cryptomarket vendors, accounting for 25% of all recorded transactions. This was followed by prescription drugs (20%), ecstasy (16%), psychedelics such as magic mushrooms and LSD (12%), methamphetamine (12%) and cocaine (8%).
Harmonic Closeness Centrality
The integration of multi-signature wallets and decentralized marketplaces is already underway, promising a future where online trade is both seamless and secure. Another key player is Empire Market, which has gained popularity for its extensive product listings and reliable customer support. The market’s multi-signature payment system further enhances security, reducing the risk of fraud. Similarly, White House Market stands out for its focus on privacy, requiring users to employ PGP encryption for all communications, ensuring that sensitive information remains protected.
Alphabay Reaches 60,000 Listings
DreamMarket advertised a large amount and variety of opioids with more than 4,000 opioid-related posts advertising 71 different types of opioid products on a regular basis. During the data collection period, 33 substances classified as novel synthetic opioids were identified by the eDarkTrends platform, and at the time of writing this paper, 17 of them have not yet been identified by the DEA or NMS in the United States. However, novel synthetic opioid AP-237 was first detected by the eDarkTrends NER in January 2019. It was subsequently identified by NMS labs, but nearly nine month later, in September 2019 (NMS Labs, 2019b). This example highlights the utility of the eDarkTrends platform and cryptomarket data in general for timely identification and effective surveillance of emerging substance use trends. Average total available weights, numbers or wholesale and retail listings and average prices for heroin, fentanyl, fentanyl analogs and other novel synthetic opioids advertised on DreamMarket during the eDarkTrends data collection period (22nd of March 2018 to 26th of January 2019).
Among the most notable markets, AlphaBay, Empire Market, and White House Market stand out for their robust security features and user-friendly interfaces. These platforms utilize advanced encryption methods and decentralized systems to ensure that transactions remain confidential and protected from external interference. The best darknet markets in 2025 prioritize security, reliability, and user experience, making them ideal platforms for the drug trade.
Meanwhile, betweenness centrality identifies the greatest share of vendors that do not score high for any of the activity indicators. As such, betweenness centrality is the network measure most likely to be of use to law enforcement for detecting vendors in the user base. Furthermore, betweenness centrality uniquely finds relatively more successful vendors among those with moderate activity. Notably, this effect is stronger for future success, further demonstrating its potential as an early warning signal.
On average, there were 548.7 grams of carfentanil available for purchase during the data collection period (Table 2). Our data indicate consistent availability of a wide variety of novel synthetic opioids both in retail and wholesale-level amounts. Identification of new substances highlights the value of cryptomarket data for early warning systems of emerging substance use trends.
- The seller-buyer relationship is remote and impersonal, and the market is public and open, with features designed to promote professionalism.
- Important future work includes comparing the availability and shipment origin of substances advertised on the darknet with the national seizure data to estimate the impact of cryptomarkets on substance accessibility at the national level.
- For operations security he suggests avoiding storing conversation logs, varying writing styles, avoiding mobile phone-based tracking and leaking false personal details to further obfuscate one’s identity.
- 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.
- Finally, we look at the set of top ranked users for the most promising network centrality measure and activity indicator at a specific point in time.

For other novel synthetic opioids, U-48,800 was advertised on average U.S.$.48.4 per gram for retail-level amounts and U.S.$14.2 per gram for listings offering wholesale-level amounts. U-47,700 was offered for an average price of U.S.$100.3 per gram for retail listings and an average price of U.S.$19.7 per gram for wholesale listings. Finally, “synthetic heroin” was advertised for an average price of U.S.$121.2 per gram for retail listings and an average price of U.S.$69.5 per gram for wholesale listings. For comparison, the average price for a gram of heroin was U.S.$206.5 for retail-level and U.S.$32.3 for wholesale-level amounts (Table 3).
Market Activity
Their continued growth highlights the demand for platforms that prioritize user safety and transaction efficiency. Archetyp Market offers 28,000+ listings with a 6% market share and $3.5M monthly turnover. Most users of the cryptomarkets are not novices and already have established experience in face-to-face markets. Individuals may be attracted by predictable supplies, choices and perceptions of reduced risk. Some events such as COVID-19 pandemic-related lockdowns seem to have drawn large numbers of new PWUD into the darknet 41.
Details on the network extraction process and the computation of monthly sales statistics are provided in the “Methods” section. Third, this research describes the amounts of novel synthetic opioids available through the listings, and information on the actual amounts of substances sold on DreamMarket remain unknown. Forth, shipment origin data were only partial and, in some cases, may not represent the real origin of shipment, which, in turn, could have contributed to bias in the shipment origin calculation. Finally, the weight used to differentiate retail from wholesale quantities was set arbitrarily and requires further investigations to allow a more precise quantification.
Jardine emphasized that illicit cryptocurrency transactions represent only a minor share of total crypto activity. 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.
