Ethereum Roadmap Calls for Major Protocol Overhaul

Ethereum is preparing its largest protocol overhaul since the 2022 Merge, according to an updated roadmap presented by co-founder Vitalik Buterin. The plan, internally called Lean Ethereum, targets nearly every major component of the network over three to four years. It elevates quantum resistance and privacy as core design goals rather than later additions.

Researchers met in Berlin two weeks ago to refine the plan, following earlier discussions with client teams in Svalbard in April. Buterin shared a revised strawmap on July 4, 2026, showing updated priorities. The roadmap builds on a framework first presented in July 2025.

It aims to keep disruption to existing applications low while steadily increasing network capacity through upgrades such as Glamsterdam and Hegotá.

The plan calls for redesigning cryptography and data storage used by rollups to support quantum-safe components. It also seeks to make private, intermediary-free transactions a default feature. Verification methods would shift toward recursive STARKs, allowing nodes to check compact proofs instead of re-running every transaction.

The current flexible state would grow only moderately, with new, more restrictive state types added to improve scalability. Buterin noted the network may eventually move beyond its current virtual machine, with RISC-V cited as one candidate architecture.

Capacity increases are expected to continue, with larger data limits and shorter block times planned over roughly five years.

Ether rose more than 12 percent in the past seven days to about $1,777, according to CoinDesk data. The roadmap remains a long-term effort, with most changes years from implementation.
