Analyzing data based on the Blockchain seems conceptional more difficult than simply analyzing unstructured data. The problem is that for an efficient analysis not only the pure data should be considered, but basically the structure of the network or the structure of the transactions as well. So, from a theoretical point of view, not only classical data analysis techniques should be used but elements of advanced network and graph theory as well. Similar theoretical elements can be found for example in different analytics tools for social physics.
