In June, we launched Protocol, reorganizing the Ethereum Basis’s analysis & growth groups to higher 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 at the moment with Scale L1 — anticipate follow-ups about Scale Blobs and Enhance UX quickly!

Geth-ing Severe 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 intensive engineering expertise on Geth mixed along 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 can allow us to Scale L1 as rapidly as potential.
In the direction of a 100M Mainnet Gasoline Restrict
Our quick aim is safely scaling Ethereum’s mainnet gasoline restrict to 100M per block. Parithosh Jayanthi, carefully supported by Nethermind’s PerfNet group, is main our work getting via every incremental enhance.
On the current Berlinterop occasion, consumer groups considerably improved their worst-case efficiency benchmarks, enabling the current enhance to 45M gasoline — a primary step on the trail towards 100M gasoline and past!
Moreover, consumer hardening has turn out to be 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 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 is able to repeatedly prune historic knowledge past a set retention interval. This can maintain 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 essential advantages:
Allow parallel transaction execution inside blocks.Facilitate parallel computation of state roots, considerably dashing up block processing.Enable preloading of required state firstly 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 gasoline limits and quicker block processing.
Benchmarking & Pricing
An ongoing problem in scaling Ethereum is aligning the gasoline prices of EVM operations with their computational overhead. The efficiency of worst-case edge circumstances at present limits community throughput.
By bettering 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 gasoline restrict commensurately.
Ansgar Dietrichs leads efforts targeted on focused benchmarking and engineering interventions, knowledgeable straight 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 situations.
In parallel, Carlos Pérez spearheads Bloatnet: an initiative aimed toward benchmarking and optimizing state efficiency. This entails testing node efficiency below situations with state sizes double the present mainnet and gasoline 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
As we speak, 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 have to 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 we’ve actual time proofs and makes use of them to satisfy its validator duties.
As soon as the prototype is prepared for mainnet, it can roll out as an non-compulsory verification mechanism. We anticipate a small group of nodes to undertake this over the following 12 months, permitting us to construct confidence in its robustness and safety.
After this, Ethereum nodes can step by step transition to zk-based validation, with it will definitely turning into the default. At that time, L1’s gasoline 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 strain as they serve intensive 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 need to develop our experience on this area.
To that finish, we’re actively hiring for a Efficiency Engineering Lead. Functions shut August 10. Should you’re as excited as us about scaling the L1, we would love to listen to from you!
