Sarah Meiklejohn (PhD ’14) was a computer science student when the revolutionary paper “A Fistful of Bitcoins: Characterizing Payments Among Men with No Names” was published in 2013. Nearly a decade later, the research team led by Meiklejohn is still credited with shedding light on the structure of the Bitcoin economy and how it is used. Their paper was recognized with a Test-of-time Award at the Association for Computing Machinery’s Internet Measurement Conference (IMC) 2024 held recently in Madrid, Spain.
The story behind the paper and its impact on cybercrime was chronicled in a 2024 book, Tracers in the Dark: The Global Hunt for the Crime Lords of Cryptocurrency, by award-winning author and veteran cybersecurity reporter Andy Greenberg. Several chapters recounting Meiklejohn’s pivotal role in tracing these illicit transactions were featured in a WIRED magazine article also by Greenberg.
Other CSE alumni involved in the work are Marjori Pomarole (B.S. ’13) and Kirill Levchenko (PhD ’08).
