Of course proof of work has always been used to decide consensus parameters. It&#x27;s just tuat no controversial changes &#x2F; failures to change have ever been put to the vote.<p>As long as the changes are non controversial then miners and nodes simply act at a rubber stamp. But it&#x27;s unrealistic to think no important issues will be controversial.<p>If consensus changes arent up for CPU vote, then you tell me what happens if a supermajority of miners and nodes decide to run software with different consensus rule from Core? Sounds like a CPU vote too me.
