Blind Bitcoin Transfers
A mixing service which is an implementation of David Chaum's blind digital cash scheme.
Client-side cryptography is done in the browser.
This service was first seen in June, 2011. In August, 2011 the site displayed the message:
Closed for the foreseeable future Somebody found an exploit in the code on this site. I am working on finding it, but, in the meantime, I have decided to get out of this business.
When transferring funds to the service, a fee is added. Though there was no fee schedule found on the site various amounts were used and the fee appears to be a flat 0.02 BTC per transfer.
