Many readers of this list have heard about the work that Scott Stornetta and I have done, beginning as Bellcore researchers a few years ago, on the problem of cryptographically secure digital time-stamping. In 1993 Bellcore spun off a company in order to commercialize this work. The company is called Surety Technologies, and we call our product and service the Digital Notary(tm) System. I am happy to report that we have just launched the product. To read about it, as well as to get the software, please visit our World-Wide Web home page: http://www.surety.com You can get the software and installation instructions directly by anonymous ftp to ftp.surety.com in the directory /dns/windows. Scott and I would both like to thank those readers of the list who have offered us their support, encouragement, and advice over the years.
