Etherum have no stratum support or Gui wallet.
Then what are the pools implementing on their servers? they are implementing something and I want to know what is it... any idea where I can find that info ?
Servers use the Geth client (Go). I don't know any more details, but keep in mind that there are 3 different ethereum clients, Go, C++ and Python. The most populars are the Go and C++.
Most miners use the C++. Digg a little of information and email some pool owners to see if they answer your question.
Popular pools are ethpool, nanopool, supernva, weipool, etc.
