Ethereum moved from proof-of-work (PoW) to proof-of-stake (PoS) consensus last month and the transition is dubbed the Merge. The PoW algorithm previously rewarded miners for validating blocks of transactions and the PoS algorithm eliminates the need for miners. The miners consumed high electricity to validate blocks and the PoS systems considerably reduces energy consumption by nearly 99%. This makes ETH more scalable and energy-efficient giving opportunities for investors to earn passive income
