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. The months and years after Silk Road’s closure were marked by a greatly increased number of shorter-lived markets as well as semi-regular law enforcement takedowns, hacks, scams and voluntary closures. Fifth, we consider the lifetime of each entity i at time t, defined as the time interval between the first and the last transaction performed by the entity until time t, denoted by \(\ell _i(t)\). This feature is satisfied when \(\ell _i(t) \ge L\), where L is the fixed value of minimum lifetime. From 2012 to 2016, the largest component of S2S network continuously grows in number of nodes and connections, as shown in Fig. Then, during 2017 and 2018, it shows the structural change due to operation Bayonet, when it shrinks.
Detecting Vendors In The User Base
Moreover, the number of multibuyers increases, which suggests a fast response from buyers to external shocks by trying to diversify their sources. Regarding profits, darknet vendors do not have to limit their trading to face-to-face interactions, and can instead sell drugs to a potentially worldwide customer base. The detection of stable U2U pairs in the full network is done by using an evolving activity-driven model31, which introduced a statistically-principled methodology to detect the network backbone against what is expected from a proper null model. If a U2U pair occurs significantly more than what expected from the null model, it is labeled as stable, otherwise it is labelled as non-stable, see Fig. The evolving activity-driven model is an appropriate methodology for large temporal networks32 and it is implemented in the Python 3 pip library TemporalBackbone45, where default parameter values have been used.
- Hence we do not distinguish multisellers by the number of markets in which they operate.
- In Figure S3, we illustrate the number of transactions, trading volume, and lifespan of U2U pairs.
- Vendors with high completion rates gain trust, reflected in detailed review sections.
- All data needed to evaluate the conclusions in the paper are present in the paper.
- Cryptomarkets now also operate via messaging apps — harder to index, monitor, or shut down.

To analyse the connectivity of the whole ecosystem, i.e., how markets are connected with each other, we consider sellers and buyers that are simultaneously active on multiple platforms. In particular, multihomers that are sellers in multiple markets are multisellers, and similarly for buyers we have the multibuyers. Specifically, to be classified as a multiseller, a user must be classified as a seller in at least two markets simultaneously.
Previous studies reported that COVID-19 had a strong impact on DWMs due to delays and damage to the shipping infrastructure caused by border closures37,38. 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.
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. Thus, a high directed weighted betweenness centrality can be interpreted here as a good indicator of vendor success.
- Notably, the effect seems to be even stronger for future success and this is moreover confirmed to hold for other months in Supplementary Material Section S3.
- The column “overall market share” for each product group shows the amount of the total sales recorded in the dataset that are attributable to sellers within each country.
- 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.
- 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.
- All regressions were run with robust standard errors using the Huber-White sandwich method to account for a lack of normality in the dependents, heteroscedasticity, and data points with high leverage owing to the nature of the data collection process.
The Dark Web And The Future Of Illicit Drug Markets
After the first month and with the exception of July and August 2014 for betweenness centrality, Fig. 2c demonstrates this also holds when comparing the top with the sub-top percentile. Interestingly, trend changes for most measures follow cryptomarket developments. For example, up until May the difference score increases monthly, similar as to how the level of activity on the cryptomarket increased during this period. The following period, up to the November 2014 “Onymous” disruption5, shows stable but slightly decreasing difference scores for most measures.

The starting point for this paper is the identification of U2U networks around DWMs. We analyse 40 DWMs for the time period spanning from June 18, 2011 to January 31, 2021. Our dataset covers all major DWMs that have ever existed, as identified by the European Monitoring Centre, Europol, the World Health Organization, and independent researchers24,25,26.

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. Ease of access also alters localised drug cultures, with for example 2-CB becoming more common in some rural areas of Scotland due to darknet access. The availability of controlled substances is mediated through two broad and interrelated distribution types. Social supply between friends and acquaintances relies on a moral economy of sharing and reciprocity 1.

Germany had the lowest percentage of users in the population for both stimulants and sedatives. The work reports usage rates in EU countries slightly below those seen in the USA (20% lifetime usage vs between 7 and 13% in EU). Evolution was active from January 2014 until March 2015, when it closed due to an exit scam. It formed a combination of a carding forum, where card information (e.g., credit/debit/ID/etc.) is traded, and an underground drug market25. Darknet markets — also known as cryptomarkets — provide a largely anonymous platform for trading in a range of illicit goods and services.
Finally, after this disruption, we see a small increase in difference scores again. Previous analyses of U2U trading relationships around DWMs include only two studies21,22 based on unstructured21 or semi-structured22 interviews of 17 users of Silk Road and 13 sellers on various DWMs, respectively. Here, we dramatically extend previous work by exploring the collective emergence and structure of U2U pairs. First, we observe that the U2U network, formed by all transactions between pairs of users, has a larger trading volume than DWMs themselves. We then identify stable U2U trading relationships, which represent a subset of persistent pairs in our dataset31,32 forming the backbone of the U2U network.

Tor is an internet service which protects those who use it from monitoring and promotes anonymity through data routing and encryption. It also permits services to be hosted anonymously, using what are called onion or location-hidden services. A server can be connected to the Tor network without its location being detected. Opioid dependency products are also dominated by the USA, potentially a reflection of the ongoing opioid crisis in that country coupled with their supply restrictions (Hadland & Beletsky, 2018). The dataset is used alternatively as a longitudinal dataset to uncover trends in the data and as a whole to represent total market activity.
