If you're interested, here's a secp256k1 implementation (underlying elliptical curve cryptography) in pure Haskell: https://github.com/wyc/haschain/blob/master/Secp256K1.hs https://github.com/wyc/haschain/blob/master/Secp256K1.hs Should probably wrap it into a Group or something. Of course it's not secure, just for fun.
