Using credentials as an ecash coin is a simple use-case. For Chaum you need
an Issuer public key per denomination. For Brands you use one attribute as
the denomination and a single Issuer public key.
Note Brands credentials even though patented have been released with an
open specification by microsoft. Details on the page above.
(I started converting the library serialization format to match the open
spec as it was implemented before the spec was released).
