"What about Miners?
Miners are suppliers of blocks, nothing more. Nodes demand consensus-compatible blocks as a vessel for key reassignment. Miners’ ability to influence the protocol is limited to the wiggle room within the protocol’s magic numbers.
For example, they can limit blocksize if they can cooperate and coordinate over shared incentives, and they can exclude transactions in the same way. But when a miner exercises any power that is detrimental to consensus they approach high risks at a quick pace.
This same dynamic applies to re-orgs, 51% attacks, etc. These attacks are not only risks to miners in that there is a cost in sacrificing blocks or failing probabilities, they run the higher-level risk of being entirely ignored and excluded from extra-protocol consensus, the market itself.
Nodes actually define what a “miner” is."
I'm well aware of how Bitcoin works.
