1. A computerized merchant fraud screening system, comprising: a bus; a processing unit coupled with the bus; a network interface coupled with the bus; a system memory coupled with the bus and storing instructions configured to instruct the processing unit and the network interface to: retrieve a list of known fraudulent merchants; retrieve a plurality of historic cryptocurrency transactions; generate, an electronic fingerprint for each fraudulent merchant of the known fraudulent merchants, based on one or more related transactions associated with the fraudulent merchant in the plurality of historic cryptocurrency transactions; identify relationships between the known fraudulent merchants based on electronic fingerprints associated with the known fraudulent merchants; generate data representing a first graph based on the identified relationships; receive a set of investigation information about a first merchant, the investigation information comprising an identification of the first merchant and one or more proposed cryptocurrency transactions associated with the first merchant; generate a first merchant electronic fingerprint for the first merchant based on the set of investigation information; perform, using a query engine and based on the first merchant electronic fingerprint, a first query against the data representing the first graph to identify a first plurality of relationships of the first merchant to one or more of the known fraudulent merchants; determine that a first count of the identified first plurality of relationships of the first merchant to one or more of the known fraudulent merchants is above a first threshold; perform, using the query engine, a second query against the data representing the first graph to identify a second plurality of relationships of the first merchant to one or more of the known fraudulent merchants in the data representing the first graph; and reject, by the computerized merchant fraud screening system, the one or more proposed cryptocurrency transactions in response to determining that a second count of the identified second plurality of relationships of the first merchant is above a second threshold.
