In June, we launched Protocol, reorganizing the Ethereum Basis’s analysis & growth groups to raised align on our present strategic targets, 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 in the present day with Scale L1 — count on follow-ups about Scale Blobs and Enhance UX quickly!

Geth-ing Critical About L1 Scaling
Scaling Ethereum requires reconciling formidable 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 shortly as doable.
In direction of a 100M Mainnet Gasoline Restrict
Our rapid objective is safely scaling Ethereum’s mainnet fuel restrict to 100M per block. Parithosh Jayanthi, intently supported by Nethermind’s PerfNet workforce, is main our work getting by way of every incremental improve.
On the current Berlinterop occasion, consumer groups considerably improved their worst-case efficiency benchmarks, enabling the current improve to 45M fuel — a primary step on the trail towards 100M fuel and past!
Moreover, consumer hardening has change into an integral a part of the 100M Gasoline initiative. The Pectra improve rollout highlighted a number of points brought on by community instability. It’s paramount to make sure shoppers stay sturdy as throughput will increase, even when the community quickly loses finality.
Historical past Expiry
The Historical past Expiry undertaking, led by Matt Garnett, reduces Ethereum nodes’ historic knowledge footprint. The current deployment of Partial Historical past Expiry eliminated pre-Merge historic knowledge, 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 knowledge past a hard and fast retention interval. This may preserve nodes’ storage wants manageable, whilst Ethereum scales.
Block-Stage Entry Lists
Block-Stage 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 essential advantages:
Allow parallel transaction execution inside blocks.Facilitate parallel computation of state roots, considerably rushing up block processing.Enable preloading of required state in the beginning of block execution, optimizing disk entry patterns.Enhance general node sync effectivity, benefiting new and archival nodes.
These enhancements collectively improve Ethereum’s capability to reliably deal with increased 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 circumstances presently limits community throughput.
By bettering benchmarking infrastructure and repricing operations that may’t be optimized by shoppers, we are able to make block execution occasions extra constant. If we shut the hole between the worst and common case blocks, we are able to then increase the fuel restrict commensurately.
Ansgar Dietrichs leads efforts centered on focused benchmarking and engineering interventions, knowledgeable straight by PerfNet’s complete benchmarking, to determine and resolve compute-heavy bottlenecks. Vital progress has already been made post-Berlinterop, significantly in managing worst-case compute situations.
In parallel, Carlos Pérez spearheads Bloatnet: an initiative aimed toward benchmarking and optimizing state efficiency. This entails testing node efficiency underneath situations with state sizes double the present mainnet and fuel limits reaching 100–150M, to straight inform each repricings and consumer optimizations.
Each of those efforts will inform Glamsterdam EIP proposals to homogenize useful resource prices throughout operations, enabling additional L1 scaling.
zkEVM Attester Consumer
In the present day, Ethereum nodes execute all transactions in a block when receiving it. That is computationally costly. To cut back this computational value, Ethereum shoppers may as a substitute 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 consumer that assumes now we have actual time proofs and makes use of them to meet its validator duties.
As soon as the prototype is prepared for mainnet, it would roll out as an non-compulsory verification mechanism. We count on a small group of nodes to undertake this over the following yr, permitting us to construct confidence in its robustness and safety.
After this, Ethereum nodes can steadily transition to zk-based validation, with it will definitely turning into the default. At that time, L1’s fuel restrict may improve 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 strain 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 count on 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. Functions shut August 10. If you happen to’re as excited as us about scaling the L1, we would love to listen to from you!
