  or even "open transactions" -- the OT-issuer would then be the "offshore tax haven" of today's financial system.

  There's also bitcoin tumbling services that further obfuscate transaction to the point where it's incredibly computation/time intensive to track transactions...if at all possible. They breakup transactions between hundreds of wallets before sending back to one address, similar to money laundering.

    How would this work? Having the whole blockchain available, one could write a program fairly quickly to take all of those transaction splinters and narrow it down to the real source and destination addresses.

      I think the basic idea is that you have a whole bunch of people who want to launder money (and maybe some who don't). They all transfer into a single wallet, then they all pay separately from that wallet. Now it's impossible to tell who paid what on the other side

        So then it becomes a gentleman's agreement on who owns what proportion?
        • guylhem 14y ago
          Yes, as everyone knows, money launderers are gentlemen, who will stick to their word in a gentlemen agreement. And this valuable process will be generously provided for free, by another gentleman, thus making the whole money laundering a costless operation. Basically, this whole complex service will fully guaranteed by the trust each money launderer have on their good fellows also engaged in this benevolent operation. Even without any government action or the tracking of tainted/untainted accounts, I just don't believe it may ever work that way - not with human beings at least :-)

      Since you can make new wallets at any time to spend from, the key is paying your btc into a wallet that others are paying into, and then extracting multiple different amounts to new, different wallets (and then using those for spending). If I have two accounts, one with 0.5 btc (newly created, never tracked by authorities, purchased with a relatively disposable account from somewhere like virwox) and one with 1.5 btc (potentially tracked, need to launder it), I'd pay both into a tumbler and then extract into 3-5 different accounts (like 0.2, 0.45, 0.9, 0.18, and 0.27). How do you prove, as a tracker, that those 5 accounts paid out to, involve btc from the original 1.5 tracked account? Especially when you consider the hundreds of other accounts being paid out to at the same time. Still paranoid? Rinse and repeat.

        Zenocoin argument stands. If you have access to the full bitcoin chain, can you write a mathematical proof that allows one account to transfer anonymously to another account, without using a "tumbler" mixed account? IMHO, you can't. That's the flow in anonymity, because, how do you ensure the tumbler properly operates? There is an incentive to try and "steal" from the tumbler pool. Even if it works, the tumbler could be marked as "tainted" - or any undeclared BTC account by default could be declared tainted, and taxation imposed on any incoming bitcoin, unless then come from an untainted account to another untainted account. The same logic currently applies in the real world - ie if you receive say 500k wired to your account from an account in the cayman islands, the taxman will want to have a word with you. Do you see the logic there? It was previously discussed in the thread reference in the original message.

          There's also the fact that there is zero incentive to use a tumbler unless you're doing something that you don't want being tracked, since using the tumbler has a non-zero cost.

            wanting anonymity does not imply guilt. it s not the case that if you have not done anything wrong, then you have nothing to hide.
