Nakamoto Consensus was based on 1 CPU = 1 Vote. When 1 CPU = 1 Vote stopped
being applicable, Nakamoto Consensus either ended, or morphed into what I am
saying, depending on your viewpoint. Today, we call it simply "Consensus" (since
"Nakamoto Consensus" essentially failed).
In my opinion it is over-understood that GPU, ASIC and also future quantum computing is understood as "CPU" in this context.
If as you say the nodes has weight, that weight is about only 40$/m per node.
Why do you think that the deployment of nodes is a big problem for the miners?
There is very likely miscommunication, since I do not understand what you are getting at.
But, GPU, ASIC, or Quantum Mining, do not equal CPU. That is impossible.
Validator Nodes are the only mechanism to prevent miners from breaking rules.
Miners today have the power to break rules because 1 CPU has become 1 ASIC.
If 1 CPU = 1 ASIC, then Miners could not threaten hardforks, it would still be all
or nothing with upgrades.
"Weight" of Nodes is irrelevant. Validator Nodes currently are altruistic.
Profit is worthless since Validator Nodes run on ideology. Their current Ideology
is the current protocol implementation or what they individually signal for.
Deployment of Validator Nodes are not a big problem for Miners, as long as Miners
do not attempt to break the rules. If Miners think they have more power or "weight"
than Validators, then Miners should hardfork right now and the fighting will be over.
Miners do not do this because the knowledgeable Miners understand what I am saying.
Exchanges, Businesses, Users, & etc (Economies) are the Validator Nodes. If Miners
will not hardfork without Exchanges, they are saying they need Validator Nodes.
