  Each file was parsed in order to extract all the multisender&amp;#x2F;multireceiver transactions in it, and then the collection of transactions was encoded as a standard database on our local machine.

This is definitely a very strange way of retrieving the blockchain for research purposes. Couldn&amp;#x27;t they have simply issued RPC calls to the regular bitcoind client after downloading the blockchain via the built-in peer-to-peer mechanism?</text><parent_chain><item><author>vbuterin</author><text>This is not even the first paper by Dorit Ron and Shamir on Bitcoin; they did an analysis of the transaction graph earlier: &lt;a href=&quot;http://eprint.iacr.org/2012/584.pdf‎&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;eprint.iacr.org&amp;#x2F;2012&amp;#x2F;584.pdf‎&lt;/a&gt;&lt;p&gt;And that one too was quite poorly done; from the text, it actually seemed like they thought that &amp;quot;the blockchain&amp;quot; is a file stored on blockchain.info.

It&amp;#x27;s a badly named service at the best of times.
