> And even if they do you still could be on the wrong chain because of network problems etc. If you only see one chain you don't even know if there is another chain.

this is the key thing you don't understand, i don't even need to respond to the rest of your message because of it.

with PoW even if i see only one chain i can absolutely objectively detect if something cheesy is going on by observing the difficulty of that chain. no network connectivity required. no comparison with other potential chains required. until you understand how is that different from PoS there's no point in discussing benefits and tradeoffs between these systems.

I must disagree with that.

Detecting if something is cheesy in the chain is not enough. The chain you see can be totally fine nothing cheesy you could "objectively detect" yet the chain you don't see is longer and everyone will switch there. Your "objectively detected" nothing is totally pointless in this case.

Or what about Tx censorship. A valid Tx with reasonable fee isn't included because miners/mining pools colluded to not process that Tx. You objectively detected nothing because everything on the chain is completely correct. You can't detect what isn't there.

You still come around with PoS lol dude I never in the whole thread compared PoW to PoS. PoS is totally irrelevant. If it would not exist PoW would still have the same flaws.

> yet the chain you don't see is longer and everyone will switch there

No. No it can’t. No it can’t without somebody spinning up 100%+ more hashrate. And in PoS it totally can because there is no objective truth measure attached to it.

And again, 51% attacks are not solvable in principle and all your criticisms are basically “but what if your chain gets 51% attacked?”. Well duh, 51% attacked system gets destroyed, no matter if it’s PoS or PoW, the issue is that PoS gets destroyed in many more scenarios, not just the equivalent of apocalypse.

And you did bring up PoS multiple times. If you didn’t - we would t be having this conversation at all.
