Ethereum developers have run the Glamsterdam upgrade on the Sepolia testnet, demonstrating the network's ability to process blocks with a gas budget approaching 200 million units per block. The rehearsal raised the processing budget more than threefold compared to the current mainnet limit. However, sampled blocks used less than half of that allowance, indicating that the capacity headroom is substantial under current conditions. The test is a key step before the upgrade is deployed on the Ethereum mainnet, with further testing expected.
Ethereum testnet blocks near 200 million gas after Glamsterdam upgrade rehearsal
Sepolia processing budget triples but sampled blocks remain below half capacity

Ethereum's Glamsterdam upgrade has been successfully rehearsed on the Sepolia testnet, with test blocks processing close to 200 million gas per block, a more than threefold increase over the previous limit, though actual usage remained well below the new allowance.

Analysis
Why This Matters
- The Glamsterdam upgrade could significantly increase Ethereum's transaction throughput, potentially reducing fees and congestion for users.
- The testnet rehearsal validates that the core technical changes work as designed before mainnet deployment.
- If successful, the upgrade may strengthen Ethereum's competitive position against other smart contract platforms.
Background
Ethereum uses a gas per block limit to control how many transactions are processed per block. Increasing this limit raises network capacity but also increases hardware demands on validators. The Glamsterdam upgrade is designed to raise this limit while maintaining network stability. Sepolia is one of Ethereum's primary testnets, used to trial upgrades before they go live on the mainnet.
Key Perspectives
Ethereum developers: The upgrade is a carefully planned technical improvement that increases scalability without sacrificing security. The testnet rehearsal confirms the code functions as intended.
Validators and node operators: Higher gas limits mean more processing work and potentially higher hardware requirements, which could affect smaller operators or those running nodes on consumer hardware.
Users and dApp developers: Greater throughput should lower transaction fees and reduce network congestion, improving the user experience for DeFi, NFTs and other applications built on Ethereum.
What to Watch
- Duration and scope of further testnet testing before mainnet activation.
- Any reports of bugs or instability during the remaining rehearsal phases.
- Validator community reaction to the increased hardware demands.
