Vitalik outlines 3-4 year 'Merge-level' redesign for Ethereum

Ethereum co-founder Vitalik Buterin has announced plans to completely redesign the network over the next three to four years through a long-term roadmap called 'Lean Ethereum'. According to The Block, he described the initiative not as a single upgrade but as Ethereum's third major evolution, comparable to the Merge, which will see almost all core protocol elements replaced. He added that reorganizing the data storage structure could reduce transaction fees for some tokens by more than 10x, while existing applications would continue to function without modification. Buterin also noted that the priority for quantum computer resistance has significantly increased and that this year's scheduled Hegota hard fork will effectively be the last pre-Lean hard fork.
