Generating a block template is a simple thing. Ask for a boatload of information, and go from there.
Important things to consider.
The reserved space is 13 bytes long now in the following format:
|minerNonce/extraNonce - 4 bytes|instanceId - 4 bytes|clientNonce - 4 bytes|clientPoolNonce - 4 bytes|
This is designed to allow a single block template to be used on up to 4 billion poolSlaves (clientPoolNonce)
Each with 4 billion clients. (clientNonce)
While being unique to this particular pool thread (instanceId)
With up to 4 billion clients (minerNonce/extraNonce)
Overkill? Sure. But that's what we do here. Overkill.
