Ethereum celebrates one year since its transition to Proof-of-Stake (PoS) consensus, which has reduced network energy consumption by 99.9%. However, the problems of centralization and censorship remain relevant. Most staking is concentrated in large pools such as Lido, raising concerns about the security of the network. At the same time, the practice of maximum extractable value (MEV) leads to censorship of transactions. However, after implementing Flashbots' MEV-Boost system, the censorship rate dropped from 78% to 35%. However, the liquid staking market continues to grow, reaching nearly $20 billion, thanks to the popularity of liquid staking tokens in DeFi and their affordability compared to traditional staking.
