Thanks much to Victor Dostov and Ivan Kouznetsov for their short but very
insightful discussion at DCSB of the paycash system.
At my request, Victor has provided me with more information on the paycash
transaction system, and the blinding that it does in the course of moving
money around.
It is forwarded below.
Cheers,

A more detailed description of the Paycash Internet payment system with some
math is presented in the paper (13297 bt, zip-archive of rtf-document) at

Also we obtained an independent experts' decision on the schemes of blind
digital signature used in PayCash payment system. The examination was done
for the purpose of algorithms used in the system verification, as well as
patentability judgment. To accomplish such an expertise Bruce Schneier* the
President of Counterpane Systems Company was invited. The basic topics of
experts' decision are listed below. The whole text (zip-archive in
