Currently, Ethereum is still using the proof-of-work consensus, on which Bitcoin is also built. However, the Ethereum Foundation has decided to use the more environmentally friendly Proof-of-Stake consensus for its public blockchain in the future. This switch from PoW to PoS is known as „The Merge.“ The Ethereum community has been working on the transition to Proof of Stake since 2015 and is expected to do so in the second half of 2022.
