In a mining pool, can there be any two or more nodes mining a block using the same nonce?
As I understand this. The nonce is the response to the mining hardware. Nodes process transactions AND this is not mining. The mining produces the nonce the core adds transactions and distributes them (according to block level).
This is an artifact of early bitcoin development from pre-2010 release of &quot;theory technology&quot;. You would have a hard time finding any information on this now a days. Good luck @ the onion.
