Topic: Blind Bitcoin Transfers - page 3. (Read 14896 times)
I hope this time the tumbler implementation gets the approval of the people that understand the stuff, from what i've read previous attempts had severe flaws that made them not all that helpful with anonnymizing coins
@mother_of_another: Thanks! I put a lot of work into that. Do you have any comments on usability/aesthetics?
@Oldtimer: Yes I do plan to make the site mobile friendly. I was unaware that it did not work on Android phones, but that is now on my TODO list. Thank you! Sorry about the captcha, I'm seriously considering replacing it with a different part of my API, but right now my number 1 priority is getting my code into a state that I can release tomorrow morning.

I'm sure people will find this service useful. 
Nice. Do you intend to make it Android friendly too? BTW I hate the captcha - I find the 1+1 challenges much easier.
Loving the site. Great job, it looks great and I'm sure there are some users with a need for this service.
Following this thread.
Nice clean looking site btw.
As several of you have already found out, I'm currently running a cryptographically anonymous bitcoin mixer at https://blindbitcoin.com. I was planning on keeping this whole thing under wraps for a bit longer, but since people have already discovered it, I may as well make this announcement.
The site is still a "beta" service, so please be patient while I get all the kinks worked out.
None of the existing functionality is going to go away, nor am I going to break compatibility with the way the site currently runs. Most of what I'm going to be doing over the next few weeks is bug-fixing, and cleaning up the code. I'll release my source via the link on my site tomorrow (6/7/2011) morning around 9AM EST.
Right now the site charges a 0.02BTC commission. This is how much it costs my system to transfer bitcoins internally paying a transaction fee of 0.01BTC per KB. Once I've got all the bugs worked out, I plan to charge a 0.75% commission on new transfers. Transfers already made and tokens already issued will not be subject to this new charge.
A few people have emailed me about my use of the OpenCoin protocol. I don't actually use the OpenCoin protocol as it is written. I found their paper to be very interesting and I used a few modifications that they suggested to Chaum's original protocol.
Who am I?: My name is Duncan Townsend. I am a student at the Massachusetts Institute of Technology. I started writing my website because I found David Chaum's blind signing protocol absolutely fascinating and I saw its application to bitcoin. I don't consider myself particularly well-qualified to implement crypto, so I haven't actually implemented any cryptography in the course of writing my site. All the cryptography (with the exceptions of what I mention here: https://blindbitcoin.com/security.html) was taken from someone else's published cryptography library.
I'd like to hear from the community what they would like to see in the way of explanation or features. I'll be checking this thread all day, so post anything you've got here.
