Vitalik Buterin says Ethereum is preparing its ‘biggest rebuild’ since the Merge
A revised roadmap details how the multi-year overhaul would replace nearly every major part of Ethereum’s protocol, with quantum resistance and privacy moving up the priority list. It lands as ether rallies more than 12% in the past seven days.

Summary
- Vitalik Buterin outlined an updated “Lean Ethereum” roadmap that aims to overhaul nearly every major part of the network over three to four years while minimizing disruption to existing applications.
- The plan sharply elevates quantum resistance and privacy, redesigning cryptography, data storage for rollups and core protocol features so that private, intermediary-free transactions and quantum-safe components become defaults.
- Lean Ethereum would cap growth of today’s flexible state while adding new, more scalable state types, adopt recursive STARKs for lighter verification, and eventually move beyond the current EVM, all while steadily increasing Ethereum’s capacity through upcoming upgrades like Glamsterdam and Hegotá.
Quantum safety has moved sharply up the list of priorities. Reigning theories state a powerful enough quantum computer could eventually break the cryptography that secures blockchains, a risk the industry increasingly treats as worth preparing for even if it remains years away.
