Woofun AI reports that Vitalik Buterin detailed the "Lean Ethereum" roadmap following a Berlin researcher meeting, framing it as a phased reconstruction over three to four years with significance rivaling the Merge. The plan introduces recursive STARKs for verification, elevates quantum security to replace vulnerable components, and decouples consensus for faster finality.

State layer updates aim for 2 TB of dynamic state plus 100 TB of new scalable storage by 2030, potentially reducing Gas fees by over ten times after ERC20 and NFT migrations. Privacy becomes a primary design goal across Mempool and state trees, while the VM layer plans to integrate leanISA or RISC-V alongside EVM.
