Is ETH 2.0 a PoW?
As a cryptocurrency enthusiast, I'm curious to know the consensus mechanism underlying the upcoming Ethereum upgrade, ETH 2.0. Is it indeed a Proof of Work (PoW) system, like its predecessor? Or has Ethereum transitioned to a different consensus model to address scalability and sustainability issues? Clarifying this point is crucial for investors and miners alike to make informed decisions about their involvement in the Ethereum network. I'd appreciate a concise yet comprehensive response that sheds light on the consensus mechanism of ETH 2.0.
