Big change coming in Ethereum! To give huge advantage against Bitcoin Several teams of engineers are working overtime to ensure that 'The Merge', implying the moment Ethereum switches from PoW to PoS, happens soon without compromising on safety Manoj Sharma | May 25, 2021 | Updated 14:08 IST Both Bitcoin and Etheruem currently use the Proof-of-Work model An Ethereum Foundation researcher, Carl Beekhuizen, in a recent blogpost has said Ethereum is working on a major shift which will help save up to 99.5 per cent of the energy it currently consumes. Notably, Ethereum already uses much lower energy than the most popular cryptocurrency Bitcoin. Ethereum will soon be completing the transition to Proof-of-Stake (PoS) from the Proof-of-Work (PoW) system, according to Beekhuizen.
