I've done the math for Brands digicash in ECC. I suspect it's as simple
to do for Chaums version. The basic idea is to change an exponential
into an elliptic multiply, and multiplication into an elliptic sum.
A base curve and point are used for the generator, the point is chosen
with an order of a large prime.
I have the notes burried in my basement someplace, if you like I can dig
them up and convert it to ascii.

Yup! Check out http://www.msn.fullfeed.com/~eresrch for code and
http://www.manning.com/Rosing for documentation. It's all free and clear.
(but the book costs US$48 :-)
Patience, persistence, truth,
