I posted some months ago about a proof of concept Bitcoin Bond. The sale of that bond was conducted via a forum thread.
A few months have passed, and the Global Bitcoin Stock Exchange is almost usable now. By “almost usable” I mean it has a GUI (even if not a very intuitive one). I wanted to test this for myself, so I issued a Bitcoin Bond. The terms are simple, and listed in the bond itself: You buy shares of the bond, and I pay you 1 BTC per share at December 1st, 2011. I put 52 bonds for sale right now on GLBSE, most of them for 0.95 BTC each.
By buying these bonds, you can make 5.26% on your money, guaranteed. See this forum post for more details and discussion.
