Ethereum’s Glamsterdam Upgrade Set for Major Capacity Boost

Test network achieves nearly 200 million gas limit per block ahead of public test on October 6.

Ethereum is making strides with its Glamsterdam upgrade, having recently confirmed blocks under new protocols, setting the stage for a public test scheduled for October 6 on the Sepolia test network.

As part of the preparation, Nethermind, a software provider for Ethereum nodes, successfully completed a performance assessment that demonstrated a crucial feature of Glamsterdam. The evaluation processed a staggering 570.7 billion gas in just over three minutes, averaging around 2.9 billion gas per second, while executing all 2,302 performance tests.

This testing focused on block-level access lists, which enable Ethereum nodes to access data about accounts and transactions prior to processing, allowing for parallel transaction handling. This marks a significant shift from the traditional sequential processing method, which has limited Ethereum's throughput.

Enhancements and Benefits for Ethereum

The upgrade has raised the block gas limit from 60 million to 200 million, significantly increasing the volume of transactions that can be processed in each block. This adjustment is expected to help stabilize fees, especially during high-demand periods, such as trading surges or popular token launches.

However, larger blocks present challenges, including more complex verification processes that could disadvantage smaller operators. To address this, Glamsterdam will involve specialized builders to package transactions while validators will ensure block integrity and network security, streamlining operations within Ethereum's ecosystem.

Additionally, the time for distributing block data across the network will extend from about two seconds to nine seconds, providing validators with more time to process the larger blocks that the upgrade will accommodate.

It is important to note that the 200 million gas limit is still a testing configuration and not yet finalized for Ethereum's main network. The upcoming test on October 6 will allow application teams to trial their software before the official rollout.
