Darknet markets may serve larger roles economically by acting as catalysts for new trading relationships formed off-market, according to results of a scientific study released yesterday, March 31st.
A new report published in Nature, one of the world’s pre-eminent scientific journals, concludes that user-to-user (U2U) cryptocurrency transactions consistently beat darknet market-based transactions in volume — a trend that has been in tact since the early days of Silk Road.
Researchers at the University of London, The Alan Touring Institute, and Chainalysis analyzed 31 million Bitcoin transactions found to be associated with 40 darknet markets between 2011-2021 and found that volume between direct buyer-seller transactions exceeded that which flowed through the markets themselves, for all 40 of the markets analyzed.
Even though it is characteristic of darknet markets to expressly forbid their vendors from doing off-market deals with buyers, the report found that monthly trading volume between off-market U2U pairs consistently surpassed that of on-market trading volume. To put things in perspective, the researchers found that while $7.5 billion had flowed through the darknet markets analyzed over the last 10 years, the figure traded directly between buyers and sellers during this timeframe approached $30 billion, which is three-fold greater in total amount.

The report detailed the process through which a certain percentage of buyers and sellers formed relationships on-market and then slowly moved business off-market, conducting deals directly among themselves. Several of these relationships were found to persist even after the darknet market on which they had formed closed, often exceeding the length of time for which markets were in operation. These “stable pairs” (as referenced in the report) accounted for only 1.7% of all U2U pairs identified yet accounted for 5% of the total $30 billion trading volume.
The report also found that U2U trades have been steadily increasing since the inception of darknet markets and the phenomenon seems to be resilient to any type of macroeconomic setback, only momentarily slowing down once: during the initial panic induced by COVID-19 in first half of 2020. It concludes that law enforcement efforts could possibly be better directed by analyzing the blockchain habits of individual sellers rather than that of whole market operations.
