About

Attribution, which means establishing who controls a cryptocurrency wallet, underpins crypto investigations, sanctions screening and compliance decisions. Today it is largely reactive: labels often appear only after funds have moved, and they sit in closed datasets with no shared standard for how they are evidenced, graded, updated or withdrawn. As a result, services that move illicit funds can continue to operate unlabelled. Attribution Games Berlin tests a proactive approach: identifying these services and labelling them in the format of a hackathon.

The results will feed the Digital Asset Task Force's work towards the launch of the Attribution Center: an independent, shared and standards-based attribution resource. Verified findings will go to law enforcement first and then to stakeholders with a legitimate interest. The methodology and identified approaches will be published in a paper after the event.
