So as people may know a couple of years ago microsoft purchased Stefan
Brands patent suite on digital credentials (a more sophisticated and
powerful form of unlinkable credential/ecash tech than Chaums).
Now the news is that they have released java and c# library code and
granted use of the patents under their open specification promise.
I wrote a C version of Chaum's and Brands' credentials a few years back:
Now I have to say I never read exactly what OSP allows but I think
people are viewing this as a positive thing, and if people get to use
the patents for privacy related apps that is cool.
