+Ethereum originally used proof-of-work but switched to proof-of-stake in September 2022. PoS offers several advantages over PoW, such as:
 
 - better energy efficiency – there is no need to use lots of energy on proof-of-work computations
 - lower barriers to entry, reduced hardware requirements – there is no need for elite hardware to stand a chance of creating new blocks
