Bitcoin can not provide that assurance as an attacker can rewrite history which is my major gripe with hash POW.
I thought I already made a strong argument that is not the attack vector anyone needs to be worried about. The real worry is the Bitcoin is
INSIDIOUSLY centralizing.
insidious
adjective
1.
intended to entrap or beguile:
an insidious plan.
2.
stealthily treacherous or deceitful:
an insidious enemy.
3.
operating or proceeding in an inconspicuous or seemingly harmless way but actually with grave effect:
an insidious disease.
These attack vectors are part of the problem that enables Bitcoin to potentially be insidious in the first place.
Plus you wanted to talk about solutions that are potentially superior to Bitcoin and other cryptos so here we are, talking about them.
I agree with that statement of resource expenditure, but POW is not the only way to skin the Sybil cat.
So, let's hear your idea for a better way?
I already posted up thread that I would get to this later and why.
Or is there some entitlement bestowed upon you that I am unaware of, that warrants me putting other tasks and people further up the queue on hold for the rest of the day while I do it?
