I cant remember right now, I think it was Ver that said something about an issue at 22MB block. I think we need to fix this & mine several 32MB stress tests blocks BEFORE we raise to 128MB. Anyone wanting 128MB could easily make their own 32mb block and mine it to prove that we are ready for 128MB.
I would also like to hear from Jihan/Bitmain why they don't support big blocks? I dont care if they said they wanted Big Blocks. When it came time to prove it they barely mined 2MB.
The 128MB limit on SV is going to work a lot like BU's emergent consensus. A miner has an option to set both the maximum they are willing to mine and the maximum they are willing to accept without orphaning it. If the majority of the miners don't want 128MB blocks at this time, then what their hash votes, goes. This is unlike the ABC hardfork, which will basically force miners to order the transactions in the blocks canonically, or be orphaned off, even if the majority of miners don't want to order canonically at this time.
