Re: PoS is far inferior to PoW - why are so many people advocating switching to PoS
This is not accurate. All decentralized consensus algos are vulnerable to 51% attacks whether it be PoS or PoW. Someone with enough hash power to 51% a PoW network can do so forever, or until the PoW network forks and changes PoW algos. Someone with 51% stake of a PoS coin can 51% the coin forever, or until the PoS network forks and burns the attacker's stake.
I disagree, the whitepaper showing otherwise is in my signature.
Although it depends on what you mean by "51% attack". Reversing a secured transaction - 0% probability as long as one stake is honest. Delaying transactions - can be delayed 2x the average while controlling 50% of the stake, hardly impressive.
