"Digital Cash and Monetary Freedom", my early work on anonymous electronic currency, was published by the London School of Economics in 1996. Originally, the paper was presented as part of the Internet Society's INET'95 Proceedings in Honolulu, Hawai'i, June 27-30th, 1995. It was also subsequently released by the Libertarian Alliance in their Economic Notes series and by the Electronic Frontier Foundation.
My thesis was further legitimatized by the mainstream when Professor Roger A. Arnold, currently at California State University San Marcos, referenced the work in his Economics, Edition 4 (1998) textbook for students.
