Not over the consensus parameters. You could have infinite hash power, but if your blocks are invalid they will be ignored.

  Um, I'm not sure why you are pointing to that? ISM is used for soft-fork upgrades, which do not revert existing consensus rules. You can have a ISM vote over a new block size, but old clients will still reject the bigger blocks.

    The upgrades are triggered by a super-majority of blocks of a certain version. This version maps to a possible new consensus rule. Block creation is a product of computational work. Therefore there is a precedent for CPUs/ASICs voting on the consensus rules of the system. > ISM is used for soft-fork upgrades, which do not change existing consensus rules. "Soft-forks" do change existing consensus rules. Will a miner's v1 blocks be accepted by the majority of the network today?

      Which has no relevance to this conversation about BU and block size. Block size is not a parameter you can force on upgraded nodes by soft-fork.

        You made the claim that under "Nakamoto consensus" the consensus parameters are not up for a vote. A correction seemed warranted. > Block size is not a parameter you can force on upgraded nodes by soft-fork. Isn't this what the Segregated Witness proposal[1] effectively does? The new limit proposed would be 4MB with an expected confirmed transaction throughput increase on the order of 2x. To quote Pieter: "Another way of looking at it, is that we raise the block size to 4 MB for the witness part, but the non-witness has same size."
