In an effort to keep up with the rapid growth and demands on the Ethereum network, Vitalik Buterin and
the Ethereum Foundation have set their sights on a series of strategies to optimize block size. With
Ethereum’s shift towards a rollup-centric ecosystem, the team is tackling the challenge head-on,
proposing at least five different solutions to ensure the blockchain remains efficient and scalable.

Understanding the Block Size Dilemma

The effective block size on Ethereum has seen a substantial increase, nearly doubling in the past year.
This expansion is largely due to the rising popularity of rollups and inscriptions requiring greater data
availability. Ethereum’s gas limit, a key parameter dictating the volume of computational work a block
can handle, alongside calldata, are critical in managing this growth.

Proposed Strategies for Block Size Management

Among the strategies is a proposal to adjust the gas cost for calldata from 16 to 42 gas per byte, which
could significantly reduce the maximum block size. This, however, raises concerns about the potential
negative impact on applications relying heavily on calldata, such as StarkNet.

An alternative approach involves a revised gas pricing model that aims to balance network efficiency
without penalizing calldata-centric applications. Additionally, the concept of a calldata fee market is
being considered, which would allow calldata costs to fluctuate based on demand.

Other ideas include capping calldata per block and offering an “EVM loyalty bonus” for applications that
use large amounts of calldata. These nuanced approaches are indicative of the Ethereum team’s dedication
to fostering innovation while managing the network’s growth.

The Ongoing Debate and Ethereum’s Roadmap

The Ethereum community continues to engage in a healthy debate over the best path forward. Buterin’s
recent suggestion to increase the Ethereum gas limit by 33% to improve transaction throughput is part of
this dialogue, with the community weighing the benefits against potential hardware burden.

Ethereum’s development trajectory for 2024 includes a series of updates known as the Merge, the Surge,
the Scourge, the Verge, the Purge, and the Splurge. These updates are designed to bolster the network’s
efficiency, security, and scalability, reflecting Ethereum’s commitment to evolving in response to user
needs and technological advancements.
