Ethereum has made significant progress in reducing energy consumption and becoming economically deflationary since transitioning to proof of stake a year ago, but technical challenges persist. The Merge, which took place on September 15, 2022, resulted in a 99.9% reduction in energy use and the dominance of liquid staking providers like Lido.

However, concerns have been raised about the potential centralization of validation on Ethereum due to the level of control granted to staking providers. Despite these challenges, experts believe that Ethereum will benefit from liquid staking, but there are worries about growing regulatory pressure against crypto and blockchain in the US. Vitalik Buterin has emphasized the need for decentralization through reducing costs and hardware requirements for node operators, with statelessness being his primary solution.
