FAFNER

Factoring via Network-Enabled Recursion (FAFNER) was a 1995 project trying to solve the RSA-130 factoring problem.

It was an internet-based sieving effort from Cooperating Systems Corporation. Although much human intervention was required to distribute and collate results, this project can be seen as one of the forerunners for internet-based distributed computing projects such as SETI@home and distributed.net.
