Ethereum builders outlined a “Lean Ethereum” roadmap that aims to trim layer-1 complexity portion hardening security, according to researcher Thomas Coratger on June 12 via X.
Co-founder Vitalik Buterin and researcher Justin Drake discussed the conception successful a breakout league astatine the Forschungsingenieurtagung league successful Berlin. It proposes 3 guiding targets: security, simplicity, and optimality.
‘Lean Ethereum’
Coratger wrote that the roadmap calls for post-quantum-ready signatures and reworked information availability to defender the ledger against aboriginal cryptographic threats.
He added that simplicity would travel from slimming consensus, execution, and information layers truthful caller contributors tin audit codification without steep learning curves. Optimality aims to execute little latency and overhead, keeping Ethereum competitory portion maintaining its decentralization.
Buterin illustrated the effort with 4 probe tracks already nether review. The archetypal is simply a three-step-finality (3SF) protocol that delivers accelerated artifact finality successful a compact codebase, portion the 2nd is aggregated post-quantum signatures.
A 3rd probe way focuses connected zero-knowledge virtual machines that alteration verifiable execution, with a data-layer refactor that merges blobs done erasure coding, rounding up the tracks.
Drake connected those tracks to existing strategy items, including user-experience upgrades, scalability work, and full-chain sampling.
The ‘Lean’ banner
Furthermore, Drake laid retired respective near-term proposals nether the “lean” banner, including thin staking, which would portion validator duties to the essentials.
Lean verifiability would fto low-power devices corroborate blocks with humble bandwidth. A thin crypto attack would trim the protocol’s reliance connected aggregate primitives, favoring a azygous hash relation and post-quantum schemes wherever possible.
He besides promoted “lean specs,” breaking logic into tiny modules, and “lean ceremonial verification,” starting with zk-VMs and signature aggregation.
Coratger noted the alignment betwixt these ideas and progressive engineering work, specified arsenic Fork-Choice enforced Inclusion Lists (FOCIL), zkEVM pilots, and beam roadmap prototypes.
He reported that league participants acknowledged the trouble of achieving optimality but viewed the payoff arsenic worthwhile, particularly arsenic rollups and centralized sequencers reshape Layer 2 processing.
Foundation response
Ethereum Foundation co-executive manager Tomasz Stańczak described Drake’s presumption arsenic a forward-looking synthesis of existent projects and longer-range research.
Stanczak wrote that galore ideas volition proceed to investigating portion others volition evolve, calling the roadmap an “unifying theory” alternatively than an contiguous directive. He added that the speech motivated contributors by tying today’s milestones to a broader method horizon.
Yet, Lean Ethereum remains a probe model without a scheduled hard fork proposal. Core teams program to refine plan documents, prototype features specified arsenic mini-3SF, and measure trade-offs successful moving radical calls.
