#Status
This project is now in what i'd consider v1 stage as such i dont believe there is much to add to stratum. so as of now this code is in bug fix stage only and should be considered unmaintained.
Riecoin support just implemented, needs testing.
#Description
Stratum-mining is a pooled mining protocol. It is a replacement for *getwork* based pooling servers by allowing clients to generate work. The stratum protocol is described [here](http://mining.bitcoin.cz/stratum-mining) in full detail.
