Design of Cryptopol: A serious game for teaching cryptocurrency tracing techniques to Law Enforcement

Tracing cryptocurrency transactions is a far from trivial process. This likely explains the increasing utilization by criminal networks for a significant amount of criminal activity, not just cybercrime, but any crime requiring monetary transfers [1]. It is therefore vitally important that adequate training exists and is readily available for both new and experienced investigators to ensure that they are familiar with the latest techniques, tools and trends. Traditional training methods can be costly and resource intensive, requiring highly qualified trainers to give their time to conduct training sessions. To address this issue, a training resource, in the form of a serious game, has been created. The game aims to provide a platform to improve the skills and expertise of law enforcement officers whilst reducing the workload of experienced investigators. This paper describes the collaborative design and development of the serious game Cryptopol in a partnership between Europol and CENTRIC, which is a multi-disciplinary and end-user focused Center of Excellence, located within Sheffield Hallam University. Cryptopol is the first cryptocurrency-tracing training game of its kind, used by over 1,500 people representing over 550 law enforcement agencies from across the world.
