> Do you have the ability to show that PoS is NOT as secure as PoW? yes. if you spend enough time offline - there is no possible way for you to be sure that you've synchronised to genuine chain without trusting a third party. that problem is not solvable under PoS and that problem is exactly what PoW was designed to solve. > I never said anything remotely related to this. you did, by implying that markets value bitcoin incorrectly. you also didn't show that "PoW is not wasteful" is incorrect (note that i never said "PoW is never wasteful", it's wasteful when nobody needs the proof that is being produced, but as long as bitcoin price is not zero, that proof is useful and therefore not wasteful), the statement that "if somebody can do what PoW does for less energy then PoW is wasteful" requires you to prove that somebody can actually do that before you can claim that PoW is wasteful.
