Vitalik Outlines Ethereum Long-Term Roadmap; Lean Ethereum Upgrades Over 3-4 Years

According to ChainCatcher, Vitalik Buterin recently outlined Ethereum's long-term protocol development roadmap following a research meeting in Berlin. Lean Ethereum will be a series of staged improvements over the next three to four years—comparable in significance to the Merge—rather than a single upgrade.

Key initiatives include introducing recursive STARKs to replace direct re-execution in verification, elevating quantum safety as a priority with Blob design in development, decoupling availability and finality in consensus, and expanding state capacity. By 2030, Ethereum is projected to support 2 TB of dynamic state plus 100 TB of new-type state, potentially reducing gas fees by over 10 times for migrated applications such as ERC-20 and NFTs.
