One issue I am having with this is the random dialog box that appears and doesnt go away.

It also gets slow after a while Smiley  lots of addresses. Also, something I would like to see if a way to clump together verified owners / addresses in one grouping to really be able to see what belongs where.

At the moment, I am using blockchain.info's API that rate limits me which results in data that is probably like a day old.  If piuk has it in his heart to forgive me for crashing his server, I would love another API key Tongue

Whoops!

Thanks for updating me on this, I appreciate the work that went into this, there may be reason for piuk to run his own API server where we can make requests directly against it. I've never actually been able to figure out how to get the raw data for Bitcoin Days Destroyed, otherwise I'd be using the API a lot more myself.

Hey Crazy Rabbit did you try just typing in your address (from your signature bar) in the search and clicking "Owner Address"?  It seems to work fine with me, I'd be curious why it's not working right for you http://blockviewer.com/#/owns/19JrBV8KekrJwcsyQMmKBS8EXW2hAFGss9:

As you can see, you have received 72 transfers from other owner addresses, it has been able to link 8 addresses associated with your public one, and if I were to continue clicking on the address nodes be able to pull up how much money each of those has redeemed.

RUM AND CARROTS: A PIRATE LIFE FOR ME
Very nice! I couldn't get it to load up myself, but I see where you're going with it. I'm sure forensic investigators will one day in the not-so-distant future have an application like this. Indeed you could make a nice profit for yourself producing a product like this for governments/banks already.

I would like to announce the start of a new project that attempts to not only give everyone an interactive way to visualize and interact with the block chain, but to also have an easy and fun way to determine addresses owned by the same person and how that person interacts with others: http://blockviewer.com/#/owns/1HB5XMLmzFVj8ALj6mfBsbifRoD4miY36v

In the above screenshot, the owner in the middle has 43 addresses that are all owned by him:

In addition to knowing all linked addresses, a high level network of "owners" has been constructed which can also track payments between other high level owner addresses as well:

https://i.imgur.com/hfOxS.png

Here we can see this owner entity received 183 payments from others, and sent 27 payments to other owners.  Expanding one of the owners out of the folders, it is revealed that he sent 127.37 BTC to another person (who happens to control 5 addresses).

This application exploits the weakness identified in Satoshi's original paper (pg.6 sec. 10) where he stated that "Some linking is still unavoidable with multi-input transactions, which necessarily reveal that their inputs were owned by the same owner.  The risk is that if the owner of a key is revealed, linking could reveal other transactions that belonged to the same owner." This application has constructed this high level owner network on top of the normal block chain, which is also traversable by simply clicking:

If you would like more information on how I did this, check out my use case here: http://toolongdidntread.com/bitcoin/the-bitcoin-social-network-part-1/ (Note: this database does not explicitly identify forum users yet.  I will be enabling that information later on.)

The block chain is a graph, why are we not displaying it as such?  If you would like to your public address against it, simply type in your address in the search box and select "Owner Address".  If all worked well, it will have all the other addresses that have been linked to you through the weakness, and you can see how well it determined where you sent BTC to other people.

KNOWN ISSUES:
There are so many it's tough to even begin.  This is definitely a "Use At Your Own Risk" as it is bound to crash, get turned off, shut down at any time for maintenance, etc.
The queries stop after 5000 nodes have been returned to protect the server.  I hope to implement pagination soon.
The API allows you to download subgraphs in a standardized .gexf data format that can be used by graph visualization tools like Gephi.  This will still stop queries after returning 5000 nodes.
The visualizer and client-side javascript is a mess.  I will be cleaning it up quite a bit.
It's not very user friendly at the moment, nodes are difficult to click on, and the documentation is pretty ugly.  I wanted to get this out anyway so power users could check it out.
At the moment, I am using blockchain.info's API that rate limits me which results in data that is probably like a day old.  If piuk has it in his heart to forgive me for crashing his server, I would love another API key Tongue

Anyway, I built this because its so much easier to track payments using the block chain as a graph instead of pulling up HUGE lists that are on blockchain.info.  The database is colossal, and its only getting bigger. Think of this as more of a sleuthing tool Smiley  I can't wait to hear your comments, suggestions, ideas, and the inevitable troll who says its a scam.  Thanks!
