My discussion with Jonathan Toomim in "Miner In World" WeChat group.

I'm working on a proposal for a rotating PoW changes to allow Core to survive Classic activation and bring an era of endless GPU mining to Core.
Please take the time to read it and comment.

I think the problem you are trying to solve isn't real.
I think Core and Classic will converge to friendly competition, and be on the same blockchain. There will not be an actual work between these two groups.
My 2 cents.
My estimation is that Core team will split. Some will continue to work on Core but on Classic chain, buy some will prefer to do PoW (and Transaction ID) change rather to submit to the new governance.

Edit: Interesting times. I think that two competing Chains is the favorable outcome. Each will be entitled to the name "Bitcoin" since both came into existence after hard-fork.
