13. A non-transitory computer-readable storage medium having computer-executable instructions, which when executed perform a method comprising: retrieving a list of known fraudulent merchants; retrieving a plurality of historic cryptocurrency transactions; generating 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; identifying relationships between the known fraudulent merchants based on electronic fingerprints associated with the known fraudulent merchants; generating data representing a first graph based on the identified relationships; receiving 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; generating a first merchant electronic fingerprint for the first merchant based on the set of investigation information; performing via 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; determining 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; performing, 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 rejecting via 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.
13. A non-transitory computer-readable storage medium having computer-executable instructions, which when executed perform a method comprising: retrieving a list of known fraudulent merchants; retrieving a plurality of historic cryptocurrency transactions; generating 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; identifying relationships between the known fraudulent merchants based on electronic fingerprints associated with the known fraudulent merchants; generating data representing a first graph based on the identified relationships; receiving 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; generating a first merchant electronic fingerprint for the first merchant based on the set of investigation information; performing via 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; determining 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; performing, 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 rejecting via 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. 18. The non-transitory computer-readable storage medium of claim 13 , wherein the method further comprises, extracting second data representing at least one condensed information graphlet from the first graph in response to performing the first query, wherein the first plurality of relationships are identified from the second data representing the graphlet.
