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.
- jfim 14y agoThere'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.
- chii 14y agowanting anonymity does not imply guilt. it s not the case that if you have not done anything wrong, then you have nothing to hide.
- endgame 14y agoBut guilt does imply wanting anonymity, and because actually setting up secure anything is hard, J. Random User isn't going to really do it. Look at how hard it is to get many people to set up a password manager, or encrypted email. You can't hide in the crowd if the crowd isn't there.
- jfim 14y agoIndeed, it does not. However, there does not seem to be much of an incentive to pay the tumbler's fee if someone has nothing to hide, so it's likely that only people who do have something to hide that will use such a service.

Surprisingly, yes: that's exactly the accomplishment of Zerocoin, though it's currently too inefficient to be practical. (It still requires many participants, but the "tumbling" is global and does not require any trusted pool.)
