Which means your coins are safely on their way.-sSh-There are no expiration of the BTC addresses? You are joking right? Please tell me this is a joke. If SR was compromised then every address is forever logged?Quote from: killboy on May 09, 2012, 11:22 pmTo keep the leo one step behind.Actually if squid tells the truth, SR logs everyones originating BTC addresses in a nice neat package of BTC address to UserName.I am also curious about this. We should have the option to remove our ties to previous addresses. If every address is saved for each user, then why generate a new one? If SR was compromised and we were tied to our addresses, then it wouldn't be that much more difficult for LEs to connect addresses to users! Can someone explain?Generating a new address can be useful as the Blockchain isn't a neat little list and every time you move coins across addresses you make it harder to trace a transaction but in principle yes, generating a new address doesn't greatly increase your safety if another has been compromised, it's a preventative measure. It's also true that it's not currently possible to tell through block chain analysis whether the coins you sent to another address were to an address of your own or someone else, so once again sending coins to yourself in random amounts to several addresses can help to obscure the trail.Severing the link between coins at one address and another before sending won't work for the simple reason as I explained below that Bitcoins operate on the basis of Public Key Cryptography i.e if I send you an e-mail encrypted with your Public Key you MUST use your own Private Key to decrypt it before sending it to anyone else. Mixers on the other hand do allow you to do this in a limited fashion by swapping your coins with those of others though of course you are trusting the mixing service not to abscond with your coins and that there are sufficient coins to swap around so that you don't receive any of your own back. It may however be possible to trace the flow of coins through the mixer if it can be shown you made a deposit and then later withdrew a similar amount.In short, the only truly safe method for buyers to purchase BTC is to sell goods in exchange for them and/or buy them with cash.V.
