Ethereum network has shifted from mining model (“Proof-of-Work”) to a staking model (“Proof-of-Stake”) since the Merge upgrade. The Merge is part of a series of ETH2.0 upgrades that aim to make Ethereum more scalable, more secure, and more sustainable.
An essential part of the upgrades is the introduction of staking, allowing users to stake their ETH, support the network, and earn rewards.
