Ethereum used the Proof-of-Work (PoW) consensus model to verify transactions, but in 2022, with the Merge upgrade, it transitioned to the Proof-of-Stake (PoS) model. In this new model, instead of miners, validators are responsible for confirming transactions, and they must stake a certain amount of Ether as collateral. This change has reduced the network’s energy consumption and increased its security.
