2011年，丝绸之路成为第一个非法毒品黑市，或“加密市场”。这项研究调查了两个最大的加密市场，丝绸之路2.0和Agora Marketplace。我们假设，加密市场迎合了打算转售或重新分配产品的买家，特别是以社会毒品交易的形式，并且随着时间的推移，加密市场上的购买量会更大。我们通过对销售药物分布的描述性和定性评估以及基于简单线性回归的估计趋势线来检验这些假设。数据是使用自定义网络爬虫收集的，并补充了独立研究员Gwern Branwen，社区成员和研究人员在2014年2月28日至2015年4月期间收集的数据集。观察到的需求主要是用于个人使用或社会毒品交易的数量。大多数销售额属于较低的价格范围，尽管很大一部分收入是在表明企业对企业交易的价格范围内产生的。此外，我们发现，在丝绸之路2.0和Agora Marketplace的情况下，购买规模都显着下降。结果表明，加密市场在分销和收入方面类似于传统的毒品市场。因此，将加密货币市场纳入关于减少毒品市场有害社会后果的讨论以及关于毒品市场和毒品贩运的一般讨论中是有意义的。
In 2011, Silk Road became the first black market, or "cryptomarket", for illicit drugs. This study examines two of the largest cryptomarkets which have operated, Silk Road 2.0 and Agora Marketplace. We hypothesize that cryptomarkets cater to buyers who intend to resell or redistribute the products, specifically in the form of social drug dealing, and that larger quantities will be purchased on the cryptomarkets over time. We examine these hypotheses through a descriptive and qualitative assessment of the distribution of drugs sold, and an estimated trend line based on simple linear regression. Data was collected using a custom web crawler which was supplemented with a dataset collected by independent researcher Gwern Branwen, community members and researchers in total spanning the period from February 28th 2014 to April 2015. The observed demand was primarily for quantities intended for personal use or social drug dealing. The majority of sales fell within the lower price ranges, although a significant part of the revenue was generated in price ranges that suggested business-to-business dealing. Furthermore, we found that the sizes of the purchases decreased significantly in both the case of Silk Road 2.0 and Agora Marketplace. The results suggest that cryptomarkets resemble traditional drug markets in terms of the distribution and revenues. As such, it is relevant to include cryptomarkets in discussions about potential reductions of the harmful social consequences of drug markets, as well as in general discussions about drug markets and drug trafficking.
