Ethereum's Glamsterdam upgrade raises testnet block gas limit to 200M ahead of October 6 Sepolia test.
Tech & Launches ·
Ethereum's Glamsterdam upgrade has raised the testnet block gas limit to 200M, expanding capacity ahead of a scheduled Sepolia test on October 6. This adjustment is intended to support higher transaction throughput on the test network during the evaluation phase.
The gas limit increase represents a key step in testing infrastructure changes before potential mainnet deployment. Gas limits control how much computation can fit into a single block; raising this parameter on testnet allows developers to validate performance and stability under expanded capacity conditions without affecting the live network.
It remains unclear whether the 200M gas limit will be adopted on mainnet, what the full scope of the Glamsterdam upgrade entails beyond this change, or how the October 6 Sepolia test results will influence subsequent decisions.
