Posted already on the marketplace->gambling forum, but it is relevant here as well:https://bitcointalk.org/index.php?topic=43807.0
I've been thinking a lot about gambling websites recently. Not really because I like gambling, but because I think it's quite an important market for the bitcoin economy. It's also pretty interesting morally/philosophically.
Anyway, I'm working on a basic gambling website. It's a work in progress, but the FAQ is already written, so I thought it might be a good idea to publish it already, in case someone is interesting in implementing the same design, and would like to help.http://s0.barwen.ch/~grondilu/cgi-bin/bettings.pl?faq
The main difference with other gambling websites is that I don't maintain any kind of bitcoin balance per user. Instead, I issue "prediction tickets" which are some kind of conditionnal bonds, that can be sold/purchased anywhere on internet (on a forum, IRC, biddingpond, bitcoin-otc, whatever).
