[Ethereum] ny Ether mixer / tumbler available

anonymityethermixersring-signatures

Quick checking around there are exactly two references to an Ether Mixer – this non functioning and here (r/ethereum) 24 days ago.

Unless I am missing something how can I hide the source of an ETH transfer? I have a couple of Genesis block pre sale accounts. I want to send a handful to this new Daemon DAO for the hell of it. What I don't want is anyone to trace and see it all the way back to my mega stack in my pre sale account.

Is there a direct current solution?

Or is there only ETH -> BTC -> Mixing -> ETH and then send it?

Would Shapeshift work in this fashion? ETH to them, goes where ever, they convert it on their account, send me the BTC to my virgin account, send back to buy ETH, receive in virgin ETH account, then send to the Daemon DAO?

I do think I am missing something somewhere.

P.S. I don't have any BTC and don't have money to buy it just for this, I do have lots of ETH.

Theoretically you could make an Ethereum mixer but I don't think it would be productive. This stems from 2 major flaws with mixers.

  1. Mixers aren't truly anonymous it obfuscates data but with enough computing power it can be decoded.
  2. You're spending a lot of Ethereum on transactions when you don't need to. This is true with Bitcoin as well where mixers end up costing 2%-3%.

In my opion the best way to 'clean' ethereum or bitcoin if you want to is to use a site like ShapeShift and change your ethereum into Monero (a crypto specializing in anonymity). Move that Monero to a second wallet and then transfer it back out (possibly through a second website to avoid timing attacks). The costs of these transactions are minimal compared to the costs of mixing. 

Eth #1 -> Shapeshift -> Monero #1 -> Monero #2 -> Shapeshift -> Eth #2

The transfer between Monereo #1 and #2 breaks the chain creating anonymity.

To elaborate on the timing attack bit. This would where you are 'cleaning' coin and it becomes obvious because the amount coming in is distinctly similar to an amount leaving. If you see someone bring in 37 ether and 5 minutes later the same amount goes back out to another address you might suspect what happened. To avoid this just stagger payments out over time and split it up between addresses for separate transfers.
