In June, we launched Protocol, reorganizing the Ethereum Basis’s analysis & growth groups to raised align on our present strategic objectives, Scale L1, Scale Blobs, and Enhance UX with out compromising on our dedication to Ethereum’s safety and hardness.
Over the approaching weeks, we’ll publish updates on every work stream, masking their ongoing progress, new initiatives, open questions and alternatives for collaboration. We begin right now with Scale L1 — anticipate follow-ups about Scale Blobs and Enhance UX quickly!

Geth-ing Critical About L1 Scaling
Scaling Ethereum requires reconciling bold designs with engineering pragmatism. To assist us obtain this, we have appointed Marius van der Wijden as co-lead for Scale L1 alongside Ansgar Dietrichs and Tim Beiko.
Marius’s in depth engineering expertise on Geth mixed together with his dedication to protocol safety make him an ideal match to align our scaling technique with Ethereum’s constraints.
Collectively, Ansgar, Marius and Tim have outlined a set of key initiatives that may allow us to Scale L1 as rapidly as doable.
In direction of a 100M Mainnet Gasoline Restrict
Our fast purpose is safely scaling Ethereum’s mainnet fuel restrict to 100M per block. Parithosh Jayanthi, intently supported by Nethermind’s PerfNet staff, is main our work getting by way of every incremental enhance.
On the current Berlinterop occasion, shopper groups considerably improved their worst-case efficiency benchmarks, enabling the current enhance to 45M fuel — a primary step on the trail towards 100M fuel and past!
Moreover, shopper hardening has develop into an integral a part of the 100M Gasoline initiative. The Pectra improve rollout highlighted a number of points attributable to community instability. It’s paramount to make sure purchasers stay strong as throughput will increase, even when the community briefly loses finality.
Historical past Expiry
The Historical past Expiry undertaking, led by Matt Garnett, reduces Ethereum nodes’ historic information footprint. The current deployment of Partial Historical past Expiry eliminated pre-Merge historic information, saving full nodes roughly 300–500 GB of disk area. This ensures they’ll run comfortably with a 2TB disk.
Constructing on this, we’re now growing Rolling Historical past Expiry, which can repeatedly prune historic information past a set retention interval. This may hold nodes’ storage wants manageable, whilst Ethereum scales.
Block-Degree Entry Lists
Block-Degree Entry Lists (BALs), championed by Toni Wahrstaetter, are rising as a number one candidate for inclusion within the Glamsterdam improve. BALs present a number of vital advantages:
Allow parallel transaction execution inside blocks.Facilitate parallel computation of state roots, considerably dashing up block processing.Enable preloading of required state initially of block execution, optimizing disk entry patterns.Enhance total node sync effectivity, benefiting new and archival nodes.
These enhancements collectively improve Ethereum’s capability to reliably deal with larger fuel limits and sooner block processing.
Benchmarking & Pricing
An ongoing problem in scaling Ethereum is aligning the fuel prices of EVM operations with their computational overhead. The efficiency of worst-case edge instances at the moment limits community throughput.
By enhancing benchmarking infrastructure and repricing operations that may’t be optimized by purchasers, we will make block execution instances extra constant. If we shut the hole between the worst and common case blocks, we will then elevate the fuel restrict commensurately.
Ansgar Dietrichs leads efforts centered on focused benchmarking and engineering interventions, knowledgeable immediately by PerfNet’s complete benchmarking, to establish and resolve compute-heavy bottlenecks. Important progress has already been made post-Berlinterop, significantly in managing worst-case compute eventualities.
In parallel, Carlos Pérez spearheads Bloatnet: an initiative aimed toward benchmarking and optimizing state efficiency. This entails testing node efficiency beneath circumstances with state sizes double the present mainnet and fuel limits reaching 100–150M, to immediately inform each repricings and shopper optimizations.
Each of those efforts will inform Glamsterdam EIP proposals to homogenize useful resource prices throughout operations, enabling additional L1 scaling.
zkEVM Attester Shopper
Right this moment, Ethereum nodes execute all transactions in a block when receiving it. That is computationally costly. To scale back this computational price, Ethereum purchasers may as an alternative confirm a zk proof of the block’s execution. To allow this, proofs of the block should be produced in actual time, which we’re getting nearer and nearer to.
Kevaundray Wedderburn is main work on a zkEVM attester shopper that assumes we’ve got actual time proofs and makes use of them to satisfy its validator duties.
As soon as the prototype is prepared for mainnet, it should roll out as an non-compulsory verification mechanism. We anticipate a small group of nodes to undertake this over the subsequent yr, permitting us to construct confidence in its robustness and safety.
After this, Ethereum nodes can regularly transition to zk-based validation, with it will definitely changing into the default. At that time, L1’s fuel restrict may enhance considerably — even go beast mode!
RPC Efficiency & Hiring
As throughput will increase, totally different node varieties (execution, consensus, RPC) face distinct challenges. RPC nodes particularly encounter heightened stress as they serve in depth historic and real-time state requests.
Internally, the EF’s Geth and PandaOps groups are actively researching optimum configurations for various node varieties. We anticipate the significance of this to extend within the coming years and wish to develop our experience on this area.
To that finish, we’re actively hiring for a Efficiency Engineering Lead. Purposes shut August 10. When you’re as excited as us about scaling the L1, we might love to listen to from you!
