Title: Taint Analysis Tools
Post by: OROBTC on May 14, 2014, 04:11:13 AM
...

I have tried both bitmixer.io (http://bitmixer.io) and sharedcoin.com (http://sharedcoin.com) servcies for mixing BTC, they both worked just fine, I have run them four times each.  One thing I was curious to do (and then look at taint) was to run some BTC through one service, and then use the other service on the "return trip".  That is:

1) I sent BTC from MultiBit via bitmixer to my blockchain.info wallet and then

2) Sent about the same amount of BTC back to MultiBit (a new wallet) via sharedcoin.

Once back to MultiBit, I wanted to run blockchain.info's "Taint Analysis" on these wallets.  But, I have been having trouble for over 24 hours now with getting "timed out" by blockchain.info ("Error 524")...  Over and over, with wallets at blockchain.info as well as MB wallets, same results, time out errors from blockchain.info.  A few days ago I did it with no problem.

-- Is anyone else having trouble with blockchain.info's Taint Analysis service?  

-- Are there other simple taint analysis tools that we can run?

Thanks for any help!

EDIT: Just got one of the MultiBit wallets to show up on blockchain.info's service.  The maximum taint was 11.67%, four other wallets showed taint of a bit over 11%.  Various other wallets came in with 1% - 3%, and LOTS came in under 1%.  Keep in mind that this wallet has just ONE transaction (incoming) and the BTC run through both bitmixer and sharedcoin.

Comments very welcome!

What do you mean by "taint"?

"Taint", in layman's terms (all that I can understand), refers to how traceable your "new BTC" (after run through the mixing service) are back to older wallets.

The lower the taint, the better a job the mixing service does to obscure where you got your BTC.  Here is a screen shot of blockchain.info's taint analysis (edited for privacy):

One way that someone could track your coins is by looking at transfers on the blockchain.

If someone were to know that TX1 was a transfer to a mixing service then they would look for a TX of a similar size that took place shortly after TX1 took place.

So does anyone know anything about other taint analysis tools except blockchain.info?
