Quote from: GrimWaldo on August 12, 2013, 11:36 pmAnytime I buy BitCoin from CoinBase, it goes:from CoinBase to a new wallet address on Electrum Wallet (on TAILS).from Electrum Wallet to a new address on Silk Road.If you want to follow the BTC confirmation trail, just plug the wallet address into the search box on www.blockchain.info. As I see it, the only way anyone could know that you sent BTC to SR is by knowing your target wallet address AND knowing that the address is associated with Silk Road.Well, here's the issue: you send directly from address A to address B to address C. A in this example being coinbase, B being the mid-way address, and C being silk road. There's a clear link from C back to A -- with, again, A being an address that can 100% ID you because Coinbase has your bank account -- provided they know C.How would they know C? Well, hopefully the SR tumbler wasn't written like this, but a naive and easy way to implement a tumbler would be to just randomly pick addresses that you know you own. SR owns every generated address that's associated with an SR account. So you send some coins to an account, then send some more, and more, and more... a ton of micro transactions, right. Then you just follow the trail as they bounce all over, and every address they hit you now know is owned by SR.It isn't quite as easy as all that, and as I said I hope the SR tumbler doesn't (and never did) work that way... but that's the basic idea, and one address in between probably isn't gonna help you too much. I've never tested though.
