Ethereum manufacturers have described a “Lean Ethereum” roadmap which aims to reduce the complexity of layer 1 while hardening security, according to researcher Thomas Coratger June 12 via x.
The co-founder Vitalik Buterin and the researcher Justin Drake discussed the concept during a session in small groups at the ForschunginGingieurtagung conference in Berlin. It offers three targets: security, simplicity and optimality.
‘Lean Ethereum’
Coratger has written that the roadmap calls for post-quantum-ready signatures and has reworked the availability of data to protect the big book against future cryptographic threats.
He added that simplicity would come from slimming consensus, execution and data layers so that new contributors can audit the code without steep learning curves. Optimality aims to make a lower latency and general costs, keeping competitive Ethereum while maintaining its decentralization.
Buterin illustrated the effort with four research tracks already underway. The first is a three-step protocol (3SF) which offers a rapid end of block in a compact code base, while the second is Associate Post-Ventum signatures.
A third research track focuses on zero knowledge virtual machines which allow an verifiable execution, with a data layer refater which merges blobs thanks to the erasure coding, bringing together the tracks.
Drake connected these tracks to existing strategy elements, including upgrading user experience, scalability work and full -channel sampling.
The “skinny” banner
In addition, Drake presented several short -term proposals under the “meager” banner, including lean intention, which would remove validator’s tasks to the essentials.
Lean verifiability would allow low power devices Confirm the blocks with a modest bandwidth. An approach to lean crypto would reduce the dependence of the protocol with regard to multiple primitives, promoting a single hash function and post-quantum schemes as far as possible.
He also promoted “Lean specifications”, breaking the logic in small modules and “lean formal verification”, starting with ZK-VMS and the aggregation of signature.
Coratger noted the alignment between these ideas and the active engineering work, such as the inclusion lists applied by the choice of the fork (Focil), the ZKEVM drivers and the roadmap prototypes.
He reported that participants in the session recognized the difficulty of reaching optimality but considered gain as valid, especially since the Rollups and the centralized sequencers reshape the treatment of layer 2.
Foundation response
The co-director of the Co-Director of the Ethereum Foundation, Tomasz Stańczak, describe Drake’s presentation as a prospective synthesis of current projects and longer research.
Stanczak has written that many ideas will test while others will evolve, qualifying the roadmap a “unifying theory” rather than an immediate directive. He added that the speech motivated the contributors by linking today’s steps to a wider technical horizon.
However, Lean Ethereum remains a research framework without a hard fork proposal. The basic teams plan to refine the design documents, the prototype features such as mini-3SF and to assess compromises in working group calls.
