When eth proof of stake?

Ethereum's Proof of Stake algorithm rewards participants for holding Ether in a designated wallet. The more Ether you hold, the higher your chance of being chosen to validate a new block and earn rewards. Proof of Stake is designed to provide a more efficient and eco-friendly way of validating blocks on the Ethereum network. It also helps to prevent the centralization of power, as all stakeholders have an equal chance of being chosen to validate new blocks.
