What happened to Bitcoins being anonymous?

[thallium205]

Steve, if I may ask, could you give me an address in that list that you do not own?  Also, did you ever receive 25 BTC from 'Bitcoineruk' or 35 BTC from 'Luke-Jr'?  

You may be surprised to know that the addresses that you think were not identified correctly are almost assuredly yours... But I would be very interested to know if some of them had no relationship to you. 

EDIT: removed the sending values...

Ackbar says NO!

Steve, are you sure the addresses you say you don't control aren't just change addresses that you're not seeing on the interface, but still yours?

I'm sure.  I checked against all addresses, even the change…I certainly didn't go through all of these addresses by hand, I dumped them using RPC and checked the list against that.

Well, considering your inclination to post your findings in such a public place, no.  But, I am glad you're trying to determine just exactly what kind of analysis is possible.  Wouldn't the gap be explained simply by the fact that there are people I transact with that no one on these forums would even know exists?

[Raoul Duke]

He will make something worse than posting such findings in a public place. No point on helping him to fine tune his script. Ofcourse you can be lying to him just to make him think his script has a problem lol

The RPC doesn't return the change addresses

Ah! You nailed it!
A pywallet wallet dump would show them, tho.

I tell reporters that Bitcoin is more private than using any other online payment method, but less private than cash (unless you know a lot about how it works under the covers and jump through several hoops to keep your identity secret).

At least you don't leave your fingerprints, DNA, and traces food and germs you ate on bitcoins. Add to that surveillance cameras and dogs. Now that I think of it cash is quite icky.

Don't forget blow..... I was told once that something like 90% of $20 bills would test positive for cocaine.

And don't forget hookers. I was told once that hookers are always paid with cash

I'm going to assume they're change addresses (no time to mess with pywallet).  I didn't realize RPC doesn't list all of them…though curiously it lists more than in the UI).

I presume you're just doing a simple analysis that looks at all transactions where that address is an input and gathers all the other input address from those transactions.  That got me thinking…how would you make that more private?  Maybe you could devise a "sprinkling service" …you could craft a transaction that sent coins to wherever and then send it to the service…the service would add some additional inputs and output ...basically moving some additional coins between some wallets that the service owns.  The service could require that some coins be offered as a fee.  There's probably some way of making that work with p2sh such that the service never has access to the coins being sent.  With something like that, you could no longer assume that all the inputs of a transaction originate from the same wallet (you can't really assume that now, but I imagine nearly all transactions are like that today).

I am not quite yet ready to open it up to active development, though my timeline is about 2 weeks from today.  

Good. the allinvain thief, mybitcoin theif, bitcoin7 thief, bitcoinica feb 2012 thief, bitcoinica (linode) thief, bitcoinica (rackspace) thief, etc., should all be shaking in their boots by now.

Hrm... I might see a pattern already...

Correct me if I am wrong but I barely use blockchain and I was taking a look at it and it shows you a map of all the coins being sent in the world.
This is suppose to be all anonymous..

You can see all the transactions but you don't know who owns each address

Also what you are seeing is the TX being relayed which isn't necessarily the IP/location of the sender.

I use the term "private". Anonymous sounds like you have something to hide, private sounds like you have the right to hide something.
