Apparently Prosper.com submits each loan profile to the SEC, which causes it to end up searchable on EDGAR.
There have been several loans appearing since 2011. Here's the most recent:
Description: INVESTMENT IN EQUIPMENT
Purpose of loan: This loan will be used to purchase 10 Butterfly Labs BitForce SHA256 singles.
These SHA256 hashers should add to my income as well. They will be used for "mining" Bitcoins, and at today's rates, they would mine around $30/day of Bitcoins ($900/month). All Bitcoins mined will be put directly back into this loan in the hopes of paying it back early (within a year is my goal).
This might be the transaction:
Ah, very cool. I got my loan through prosper.com. Looks to be very similar to lending club. My interest was 22%, lol.
Interesting to see Bitcoin pop up in all these various places.
