In this paper, we investigate the challenge of integrating heterogeneous, dis-tributed data sources using semantic technologies to enable the answering of complex user queries on the combination of available data. Our solution uses a common OWL ontology that contains the concepts that represent the data in all the distributed sources providing maximum querying flexibility towards the user. Retrieval of specific data from distributed sources is done using a set of customized rules and built-in functions that call the data sources APIs triggered when a user issues a SPARQL query.

In this poster, we will present attendees how the recent state-of-the-art Semantic Web tool SANSA could be used to tackle blockchain specific challenges. In particular, the poster will focus on the use case of CryptoKitties: a popular Ethereum-based online game where users are able to trade virtual kitty pets in a secure way.
