The relative (a) and absolute (b) difference score between vendors over non-vendors. Whereas their measure relied entirely on forum post texts (and thread titles) for the selection of posts and computation of the sentiment, our activity indicators can be determined entirely independent of post content. These measures rely on the fact that the more topics a user has started and the more engagement those topics received, the greater the likelihood that they are a (successful) vendor. To evaluate the network measures we compare them against three activity indicators, which serve as our baselines.
Untangling The 'Dark Web': New Study Shows Steady Growth Of The Online Illicit Drugs Trade
This dataset consists of data on the forum and the market, as well as data that links forum users to market users, i.e., vendors. The identification of key players in cryptomarkets such as successful vendors and administrators, is a vital step in law enforcement interventions. 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. However, many cryptomarkets do not record sales information and at best provide a label to vendors independent of their success. Interestingly, considering users with higher betweenness centrality in the communication network further improves performance, also identifying successful vendors with moderate activity on the forum.
This allowed for classification of most medications, although in some instances where a specific medication was not included in the BNF due to it not being licensed in the UK, it was placed in the most appropriate category based on its main indication and its pharmacological similarity to other drugs within that category. The specific drug products present in the listing were classified into 7 groupings based on the British National Formulary (BNF) legacy classification system, which classifies prescription medications according to their main indication or intended use. Using established methods for analysis based on DATACRYPTO, the majority of the analysis presented, unless otherwise stated, was restricted to active products (those products that had received at least one feedback in the previous 30 days) to account for dormant, fake or otherwise irrelevant listings.

Individuals who are more affluent and better connected have often continued drug consumption with little interruption. The pandemic has affirmed and extended existing inequalities , and the digital market has contributed to that. Having said that, user people will be consuming at places where services may be present, such as raves and festivals, but the rise of at-home delivery means that both distribution patterns and locations of consumption are changing. The context is a general expansion of convenience, with changed spatial/territorial supply practices and adaptive social/technical networks . Televend is an example of an automated system that uses the Telegram app to mimic some attributes of cryptomarket systems .

The intermediate resilience regime of the S2S network. The same pattern is observed in the whole S2S network (see Supplementary Information Section S5). Therefore, the S2S network appears to be more resilient than the multiseller network but less than the multibuyer network. However, unlike the multiseller network, the S2S network recovers during 2019 and 2020, but slower than the multibuyer network recovery. From 2012 to 2016, the largest component of S2S network continuously grows in number of nodes and connections, as shown in Fig.

High PageRank centrality is often an indicator of being well connected to other important users. The bidirectional harmonic closeness centrality29 is a measure of a user’s ability to reach the entire network, following paths regardless of link direction. Thus, it can serve as a proxy of how many users have seen one or more of their posts and thus to some extent their level of name recognition. The in-degree of a user indicates the number of different users that posted (shortly) after them on the same topic(s).
Methamphetamine and cocaine were approximately three times more expensive when purchased from an Australian cryptomarket vendor. For example, average prices for ecstasy sold by Australian vendors were more than six times the price of those sold by their foreign counterparts. More than a quarter of the world’s darknet methamphetamine trade (27.1%) is facilitated by Australian cryptomarket dealers. In contrast, 57.51% of vendors managed to sell drug items worth less than USD 10,000 within a period of twelve months. 1) Total sales volumes for the ‘drugs' section was estimated at approximately USD 94 million for the period from September 2015 to August 2016. Interviewees rationalised their participation in the dark web drugs trade in a variety of ways.
But it is not just the obscure parts of the Internet where drugs are on offer. Many web shops on the open Internet offer new psychoactive drugs as 'research chemicals'. But it is not just the obscure corners of the Internet where drugs are on sale. Sales of drugs used in the treatment of opioid dependency are also substantial in the USA. They also report fewer instances of threats and violence when compared to sourcing drugs via conventional means. They have greater knowledge regarding the composition of illicit drugs and are able to access information regarding safer forms of drug use.

These advancements will further solidify their position as a secure and reliable option for users worldwide. The use of encrypted messaging and secure payment methods ensures that transactions remain private and secure, fostering a thriving environment for trade. These platforms leverage advanced encryption technologies, decentralized systems, and user-friendly interfaces to ensure seamless transactions.

The reason is that the operational structure of DWMs inherently hides the seller–buyer link, as all transactions are made through the marketplace. Moreover, data scraped from the DWMs cannot assess the U2U transactions which account for the largest fraction of the total trading volume of the ecosystem13. In particular, these studies are based on user reviews which carry many inaccuracies, for instance, with respect to the time and value of the transaction19, that further compound error in other measures. Owing to their unregulated character, DWMs offer no formal protection to buyers and sellers. The dark web has been home to many unregulated online commercial platforms facilitating the trade of illicit goods1,2,3,4,5,6,7,8,9,10.

Therefore, we use a sliding window of \(\Delta t\) days to classify sellers, i.e., every day that an entity is classified as a seller, it remains as a seller for \(\Delta t\) days, including the first day. Conversely, because the classification is a function of time, an entity that has been classified as a seller at time t, might lose the seller status if, at a future time, the features are not satisfied. This feature is satisfied when \(\phi _i(t) \le \tau\), where \(\tau\) is the maximum value of mean interevent time. This feature is satisfied when \(\ell _i(t) \ge L\), where L is the fixed value of minimum lifetime.
Darknet-hosted drug markets (‘cryptomarkets’) are an established model of illicit drug distribution which makes use of specialised online hosting and payment systems to link buyers and sellers remotely. Monthly vendor recall of top vendor percentile (top 0–20% vendors in terms of sales) among the top 20% of all users based on the network measures and activity indicators. In this paper, we investigate to what level employing network measures computed on user-to-user communication networks are useful in identifying both current and future successful vendors on cryptomarkets. Additionally, we singled out the multihomers, i.e., users that are simultaneously active in multiple markets, acting either as sellers (the multisellers), or as buyers (the multibuyers). Specifically for buyers, when we compute the union or intersection of sellers across markets and the U2U network, we remove entities that are sellers in any market or the U2U network in that time period.
Online And Offline Determinants Of Drug Trafficking Across Countries Via Cryptomarkets
Thus, a high directed weighted betweenness centrality can be interpreted here as a good indicator of vendor success. 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. Additionally, betweenness centrality has been shown to perform well in identifying key players in criminal networks14,20. In other words, it measures how important a node is with respect to connecting various communities in the network. Betweenness centrality30,31 measures the extent to which a node is on shortest paths connecting pairs of nodes in the network.
In some instances where a specific medication was not included in the BNF due to it not being licensed in the UK (e.g. etizolam), it was placed in the most appropriate category (i.e. ‘hypnotics and anxiolytics’) based on its main indication and its pharmacological similarity to other drugs within that category. With regard to stimulants the results clearly point to the highest usage rates being found in the USA, with other markets representing only a fraction of that share. Denmark and Austria both demonstrate high and consistent levels of sales for these products, and Sweden increased from a high base (over 20% of all sales) by close to 10 percentage points per year. Norbutas (2018) found that markets are constrained by their wider geography, particularly border controls, and the findings from within the Schengen area countries are complex. It is well established that Australia is a relative island when it comes to the online trade, and although hypnotics and anxiolytics represent 7.2% of all trade in that country – a cause for concern for policy makers there – there does not seem to be any change in the levels indicating the problem is likely not worsening. Towards the end of the time period there is a marked increase in the amount of the UK market represented by alprazolam.
On average, there were 548.7 grams of carfentanil available for purchase during the data collection period (Table 2). There was a total of 45 listings (out of a total of 568 fentanyl analog listings) for carfentanil, an extremely potent fentanyl analog that is also used in veterinary medicine as a large animal tranquilizer. Among fentanyl analogs, furanylfentanyl was the most commonly advertised (217/568) with an average of 2.3 kg offered for sale at each data point, followed by methoxyacetyl-fentanyl (103/568), and 4-fluoroisobutyrfentanyl (101/568). Eleven fentanyl analogs (acetylfentanyl, burtyrfentanyl, butyrfluorofentanyl, carfentanil, furanylfentanyl, methoxyacetylfentanyl, orthomethylfuranylfentanyl, 3-methylmethoxyacetyl-fentanyl, 4-fluorobutyrfentanyl, 4-methoxymethylfentanyl (R-30,490) and 4-phenylfentanyl) and three precursor chemicals (advertised as 4-ANPP, 4-APPP and APPP) were identified over the data collection period.
This ensures that transactions remain untraceable, providing a layer of security unmatched by traditional online platforms. As these markets continue to grow, they are likely to incorporate even more sophisticated features, such as AI-driven recommendations and enhanced security protocols. From pharmaceuticals to recreational substances, users can find a wide range of options tailored to their needs. By leveraging cutting-edge technologies and prioritizing user safety, these platforms have solidified their position as the go-to destinations for reliable transactions. Additionally, the integration of privacy-focused cryptocurrencies, such as Monero, has provided users with even greater anonymity options.
In June 2015 the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) produced a report citing difficulties controlling virtual market places via darknet markets, social media and mobile apps. Some users report the online element having a moderating effect on their consumption due to the increased lead time ordering from the sites compared to street dealing. Whilst a great many products are sold, drugs dominate the numbers of listings, with the drugs including cannabis, MDMA, modafinil, LSD, cocaine, and designer drugs. Many vendors list their wares on multiple markets, ensuring they retain their reputation even should a single market place close. Some criminal internet forums such as the defunct Tor Carding Forum and the Russian Anonymous Marketplace function as markets with trusted members providing escrow services, and users engaging in off-forum messaging. By 2015, some of the most popular vendors had their own dedicated online shops separate from the large marketplaces.
