How does proof of stake increase security of the Ethereum blockchain as compared to the proof of work, which has pretty much been solid since the inception of the network?
I'm not part of the coding team, those were the promises of the foundational members last week. I think when it is done, we will have more understanding about the upgrade. The general 5 phase upgrades might have increased the security of the system when done, while the proof-of-stake would increase reliability within the system.
