my reference to Peters argument above aid nothing about mempool; I was talking about block verification times. You're obfuscation again.
In your message to me you argued that f2pool was SPV mining becuase "the" mempool was big. I retored that their mempool has nothing to do with it, and besides they can make their mempool as small as they want. You argued that the mempools were the same, I pointed out that they were not. You responded claiming my responses was inconsistent with the points about verification delay; and I then responsed that no-- those comments were about verification delay, not mempool. The two are unrelated. You seem to have taken as axiomatic that mempool == verification delay, a position which is technically unjustified but supports your preordaned conclusions; then you claim I'm being inconsistent when I simply point out that these things are very different and not generally related.
Yes, that's exactly what happened. It's very kind of gmax to so diligently care for our enfeebled but honored elder by chewing his food, changing his diapers, wiping the drool from his chin, and forgiving his inability to form new memories (much less understand new concepts). Gmax is a saint for lovingly patting Dr. Frappe on the head when he gets cranky, instead of reaching for the Thorazine.
It's possible to construct a contrived block today that takes many minutes to verify, even within the 1MB limit; though a miner that did that would mostly be hurting themselve unless they had some arrangement with most of the hashpower to accept their block.
I'm fascinated by the trolling and research possibilities of such 'contrived' blocks. Generating them seems less expensive than the brute force high-fee crapflood attacks recently used by the Gavinistas, but it isn't in their interest to publicize them as they contraindicate their desired (>)>1MB blocks.
In order to optimize their contrivance, one would have to understand how best to exploit the weaknesses of Createnewblock's existing inefficiencies. OTOH, being able to generate such extra-obnoxious blocks provides an excellent tool for testing proposed optimizations.
