Really hope there comes a way to mix them with security by design without needing to hope that the service is not a honey pot.Blind mixing allows coins to be mixed without the mix operator being able to gain any information even if they are malicious. I think I am going to implement a blind mix right now actually, maybe I will charge a bit to use it or maybe I will give it to SR to run and hope he compensates me a little.Thing is. How to prove to somebody who has just arrived at your service that this is indeed a blind signature mix, and not just a regular bitcoin laundry service? Somebody with no programming knowledge to audit open source code? Otherwise there's no comparative advantage for a blind sig over a normal mix, because you're back to trusting 'authority' i.e. other SR people or the mix owner that it all works according to plan. Maybe I haven't read the work on blind signature mixers properly, but if I'm right, then this is serious problem for anybody implementing a mix.Also, it would need to be tested per mix cycle in case a LE agent was doing a bait 'n switch with a blind signature mixer and a normal mix. Block chain looks the same, but you're potentially linkable to a transaction if your anonymity is compromised.Surely somebody like Chaum already came up with a solution to this?
