Lean

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.
<h2 id="quantum-resistance-and-privacy-take-center-stage">Quantum Resistance and Privacy Take Center Stage</h2>
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." <cite>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.</cite>
<cite>Privacy has become a first-class goal, not an afterthought, extending Buterin's broader privacy push.</cite><cite>Rather than treating privacy as an application-layer feature, Buterin said future protocol upgrades will be designed with privacy built into their architecture.</cite> To support both goals, <cite>the roadmap explores RISC-V or leanISA virtual machine designs to support programmable privacy while maintaining scalability.</cite>
<cite>The roadmap also proposes integrating recursive STARKs, cryptographic proofs designed to verify computations efficiently, as a native verification component within the Ethereum protocol.</cite><cite>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.</cite>

The roadmap arrives against a backdrop of significant organisational change at the Ethereum Foundation. <cite>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.</cite><cite>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.</cite>
<cite>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.</cite> Protocol coordinators Tim Beiko and Barnabé Monnot also left in May.
<cite>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.</cite> 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.
