generalizethis, I promised you I would tie him in knots with his own words.
Longest Chain with the Most Difficulty Wins , PoW or PoW
They have the same protection, higher the difficulty and the longer the chain the more secure they are.
Saying Proof of stake does not have it shows you are not as smart as you think you are.
You seem to always ignore what was already written:
There is no work proven with PoS, thus no way to objectively measure the length of the chain relative to any other. The amount of computational work to produce a block is not recorded in a PoS block chain.
The quote from the OP above explains there are some strategies for cheating in PoS that are a computational race, and as smooth had explained to me last year (which I also linked to in the OP):
- smooth also added the very clever point that in the case Proof-of-Stake devolves to a computation contest for computing Nothing-at-Stake game theory, then this is perhaps a Proof-of-Work system in disguise (and I add but it might still also have some of the bad traits of Proof-of-Stake as well)
So the slamdunk is that in the case of cheating strategy where PoS devolves to a computational contest, then it is PoW but doesn't gain the benefits of PoW because the work is not recorded in the block chain, thus it can't be verified and thus as I wrote:
The only protection are checkpoints, adhoc social contract, and thus centralization.
How many times does someone have to repeat the same information for you to absorb it in your retarded skull?
Sigh. You are showing everyone what an obstinate and insolent idiot you are. Please continue trolling until you have no more reputation whatsoever.
They are not optional for PoS. This was already explained to you numerous times.
FYI2: Proof of Stake Chain Length grows with each Block and its Accumulated Difficulty
cumulative difficulty value is stored as a parameter in each block, and each subsequent block derives its new difficulty from the previous blocks value. In case of ambiguity, the network achieves consensus by selecting the block or chain fragment with the highest cumulative difficulty.
I am not aware of any PoS coin that records the difficulty of computing the cheating strategies for gaming nothing-at-stake. If you want to cite reference that proves PoS does that, then fine. But the only thing that will change is that possibly those coins are PoW coins and not PoS coins. I'll have to look at the details of anything you will cite as a reference.
