franky1, no sane Bitcoin developer will say that Bitcoin has "bilaterally split" into two. It was Bitcoin Cash that split into an altcoin, and the insane part of it is Roger Ver and his sock puppets believe and spread this misinformation that "BCH is Bitcoin".
If the miners truly believe that and would follow Jihan Wu to threaten to "kill" Bitcoin, then I believe Bitcoin will undergo a POW change as a last resort.
if bitcoin core did not change from the legacy rules .. bitcoin core would still only be using only the legacy rules
core split from the legacyrules by enabling weight to get the 4mb weight. and bitcoin cash just increased the base block to get their 8-32mb block buffer
they BOTH changed at the same time..
2 networks.. 2 different rules compared to the rule pre august. = bilateral split.
as to WHO orchestrated it.. you could argue that is was not core... but then in 2015-2016 Luke JR backtracked out of a consensus agreemnt by saying he was not part of core.
so you can play the social drama of who is or is not part of the core supporters all you like. but if you follow their salaries, you follow who they prefer to side with and who they play these silly social games for. you will see which side was which. and.. guess what
the UASF was not to continue legacy. and was not to create clams 2.0(unnilateral) it was to to be part of a mandatory planned consensus bypassing split where at the exact same block 2 separate rules came into play and the legacy blocks got killed off on that date
after all it it was a whole network of pools wanting segwit and a whole network of nodes wanting segwit.. it would have got activated in december 2016-june 2017.. but the only supporters of it were those tight to a certain team.. but ill let you play around arguing the team game social games as all i care about is code that got implimented without true consensus.
put it another way
a few years ago. some dude copied the code and set up his own network that continued a blockchain from a certain bitcoin block in a different dirction while bitcoin core changed nothing.. that was called a unilateral slit (simple fork) and that guy named his alt CLAMS
but the whole BSCartel of the bitcoin core team, Barry silbert blockstream bloq all converved the august plan where BOTH bitcoin cash began and segit began
learn #478558 its an important number
bitcoin core network starting rejecting blocks that showed a legacy flag instead of a segwit flag and banned nodes that relayed such
so yes core nodes/network did change too
again if nothing changed and bitcoin core didnt fork/go in a new direction. segwit would not have activated
learn about #478558
as for advocating to change the PoW. that is foolish
first of all it will affct EVERY POOL and EVERY block. causing block hashing time delays
also making it a mandatory thing like the core advocates done to get segwit initiated is not consensus. ther would need to be a period of time to get a real true no banning/no rejecting consensus vote.. and then if there is enoughh advocation then a long period of transition to allow both algos to be acceptable to the rules before finally cutting off the old algo when the hashrate of the new algo is good and strong enough to work alone.
P.S no matter what algo is chosen big pools will be inncentivise to pool their rsources to get the biggst slice of the pie they can. so no mattr what do not think it will ever go back to a 1 cpu 1 block situationwhere everyone with a laptop has an equal chance.
a PoW change will not destroy ASICS. as ASIC manufacturers will just redesign and release a new asic and strangely enough they will actually make mor money out of it. while costing average joe more money having to replace old gear.
a PoW change should only happen if there is a flaw to current PoW. eg if sha256 was broke
