Hello, I am trying to learn how mining clients for crypto currencies work (specifically monero like the one found here https://github.com/fireice-uk/xmr-stak-cpu). What I would like do is what kind of exchange and interface is implemented between the mining client and pool. How does the client gather "work", what does this work/job look like and what the mining client does with it and how does it send it back? All references and tips welcomed.

I am planning to create the client with Node.
