Vitalik Says Quantum Safety Has Become Urgent Priority For Ethereum

Ethereum co-founder Vitalik Buterin has published a long-term development plan he calls "Lean Ethereum," outlining a sweeping set of protocol upgrades expected to roll out over the next three to four years. The plan, shared publicly via a draft known as the strawmap, touches nearly every layer of the network.

Quantum Resistance and Privacy Take Center Stage

Buterin was direct about the urgency of one issue in particular. "Quantum safety has shifted up a LOT in priority," he said, adding that finalizing a quantum-safe solution for blobs has "become urgent." He also confirmed that quantum resistance has moved significantly higher on Ethereum's development priorities, with work on quantum-safe blob designs already underway for several months.

Privacy has become a first-class goal, not an afterthought, extending Buterin's broader privacy push. Rather than treating privacy as an application-layer feature, Buterin said future protocol upgrades will be designed with privacy built into their architecture. To support both goals, the roadmap explores RISC-V or leanISA virtual machine designs to support programmable privacy while maintaining scalability.

The roadmap also proposes integrating recursive STARKs, cryptographic proofs designed to verify computations efficiently, as a native verification component within the Ethereum protocol. Buterin calls Lean Ethereum the network's third major evolution after the Merge, with upgrades spanning three to four years and touching nearly every core part of the protocol.

Foundation Restructuring Adds Pressure on Delivery

The roadmap arrives against a backdrop of significant organisational change at the Ethereum Foundation. The Foundation laid off 54 employees and announced a roughly 40% budget reduction, executing one of the most sweeping structural overhauls in the organisation's history. Vitalik Buterin framed the cuts as part of a deliberate shift to an endowment model, targeting a long-term annual spending rate of 5% of treasury assets by 2030, down from roughly 15% before this year.

Tomasz Stańczak stepped down as co-executive director in February, followed by co-executive director Hsiao-Wei Wang, bringing total senior departures since January to nine. Protocol coordinators Tim Beiko and Barnabé Monnot also left in May.

Some in the community have pushed back on the timeline. Researcher Dankrad Feist argued the three-to-four-year window is too slow and suggested AI could help developers ship the upgrades within a year, while crypto analyst Ignas Fiodorovas praised the plan but cast doubt on the Foundation's ability to deliver within the stated schedule, citing its history of missing deadlines. The strawmap is still a draft, not a confirmed schedule, but it signals clearly where Ethereum's core development priorities are headed for the remainder of the decade.
