increase sustainability and security within the blockchain as the proof-of-stake mechanism will be the order of the day as it fades off "proof-of-work" system.
Maybe I am missing something.
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?
Proof of Stake, this is ominous and disagrees with some naysayers. I'm also excited and looking forward to the upcoming upgrade, but after reading some docs, I'm also starting to worry about the decentralization of ETH going away when it's fully migrated to POS. We still can't conclude anything, still waiting for feedback from the community and whether Vitalik Buterin has any plans for that. ETH is different from the rest of altcoins because of its decentralization, once it loses decentralization I think I will stop using it too.
