Your sarcasm escaped me. Though I must admit your statement elicited some surprise, as you have indeed been otherwise consistent in your advancing the notion that the quadratic hashing time solution within The SegWit Omnibus Changeset could simply be stepped around by an attacker.

Why I am trying to tell you is that it doesn't matter. It's not a problem in any systemic sense. Market forces will conspire to orphan blocks that take an inordinate amount of time to verify. Regardless of which -- or even if any -- scaling solution be adopted.

so there has never been an excessively quadratic blocks in bitcoin.. due to faith in "time"

are you sure

careful how you reply, careful what you say next. the blockchain history never lies

No, "there has never been an excessively quadratic blocks in bitcoin". Yes, I am sure.

Of course, 'excessive' requires finesse. There has been, to my knowledge, one block in the history of bitcoin that contained a single transaction of nearly 1MB. That transaction took quite a long time to validate due to the quadratic hash time issue.

But what has been the repercussions of this event? Naddadamnthing. Well, there has been endless FUD yammering and chicken-little-ing. But in terms of the core function of Bitcoin, there has been exactly zero effect. In other words, not excessive.

Of course, if a persistent repeated sequence of such blocks were to be somehow mined back-to-back, that might slow transaction processing to a crawl*.

That is, if no other miner bothered to mine a competing block. Which, of course, is what a rational miner would do in such a situation. For then he would reap the rewards of a more-quickly validating block. (That would be the coinbase reward for solving a block).

The 'excessivity' solves itself. Through natural incentive of rational self-interest.

Sure, we should replace the current algorithm with one that scales linearly. After we address more pressing issues. Such as the cartel-like hard capped transaction production quota.

*Anyone supporting the core approach to 'scaling' has already tacitly accepted transaction processing being slowed to a crawl.
