It took me a full 30 minutes to implement and verify!

I think that at the time this group's charter was written, crypto currencies were relatively unknown.  However, over the last year they have exploded in popularity.  "Bitcoin" was one of the top 100 searches globally last year, and even has made it into the Oxford English Dictionary.

Bitcoin deployment now numbers in the millions of users and hundreds of companies.  There are also free software implementations in most languages.
