From the Cypherpunks mailing list, February 5-6, 1996:
“To follow up on a post last year where I suggested that Rabin’s information dispersal scheme might be useful for sending large files across unreliable remailer networks, I built a shareware package called Disperse/Collect out of my own Crypto++ library. Disperse splits up files into redundant pieces and encodes them in base 64. Collect decodes them and reconstructs the original files. You can download this software from my home page at http://www.eskimo.com/~weidai.”
[This post confirms that by early 1996, Wei Dai had already created and publicly released multiple software projects, including the Crypto++ cryptographic library — which would go on to be used in commercial products such as Microsoft Office Groove and LastPass. When Dai later published b-money in November 1998 without an implementation, it was a deliberate choice by an experienced programmer, not a limitation of skill.]
