If anyone knows what happened to blockviewer.com (the site's offline now), or if there are any similar applications/sites, I'm still interested.

It is still being developed.  The latest is found here: http://toolongdidntread.com

<p>The tool is called Blockviewer.  The website, blockviewer.com, no longer exists.  However, the source code is available on Github: <a href="https://github.com/thallium205/BitcoinVisualizer" rel="nofollow">https://github.com/thallium205/BitcoinVisualizer</a>.

<p>The above-mentioned site, blockviewer.com, is now down.</p>

<p>There should be some type of search/querying engine that allows you to find the addresses associated with a given address based on the classic user-generating algorithm.</p>

<p>Anecdotally, my university might be hosting such an engine by the end of the summer. We're also looking at Javascript-based visualization engines to host the data through.</p>

<p>Addresses can be grouped as belonging to the same user (or, better, same "account") by grouping together the addresses that participate as inputs to a single transaction, and doing it transitively. This has been done in the <a href="http://eprint.iacr.org/2012/584.pdf">recent paper by Shamir and Ron</a>, by <a href="http://anonymity-in-bitcoin.blogspot.com/2011/07/bitcoin-is-not-anonymous.html">some previous researchers</a> and can be done by <a href="https://bitcointalk.org/index.php?topic=88584.0">znort's parser</a>. I know this is not 100 % accurate but I'm fine with it.</p>

<p>What I'm looking for is a site that displays the results of such grouping graphically, possibly with transactions between accounts as well.</p>

<p>I've read about such a site on bitcointalk.org, but I can't find the topic any more. I'm looking for the url of the (now possibly defunct) site or the bitcointalk topic describing it.</p>

Wouldn't that be dependent on being able to associate a transaction with a geographic location?

Is there an application or a site grouping addresses by user graphically?

(Asked by: username_0 on 2012-10-24)

Addresses can be grouped as belonging to the same user (or, better, same "account") by grouping together the addresses that participate as inputs to a single transaction, and doing it transitively. This has been done in the [recent paper by Shamir and Ron](http://eprint.iacr.org/2012/584.pdf), by [some previous researchers](http://anonymity-in-bitcoin.blogspot.com/2011/07/bitcoin-is-not-anonymous.html) and can be done by [znort's parser](https://bitcointalk.org/index.php?topic=88584.0). I know this is not 100 % accurate but I'm fine with it.

What I'm looking for is a site that displays the results of such grouping graphically, possibly with transactions between accounts as well.

I've read about such a site on bitcointalk.org, but I can't find the topic any more. I'm looking for the url of the (now possibly defunct) site or the bitcointalk topic describing it.
