Hello Cafe,
You've heard of the neat crypto-currency bitcoin[1], haven't you?
Well, I've just released network-bitcoin[2] which provides Haskell bindings to the bitcoin daemon. Hopefully, this will make your bitcoin-related goals easier to achieve. Who knows, it might even make bitcoin integration for the various web frameworks a bit easier.
Special thanks to Michael Hendricks who wrote the original version of network-bitcoin, which I used as a base for this release.
Regards,
- Clark
