Ethereum Testnet Hits 200M Gas Limit Milestone

Ethereum's Glamsterdam testnet is moving ahead, bringing a 200M gas limit within reach for validators. However, this does not confirm a mainnet target or activation date.

The upgrade combines Amsterdam execution-layer changes with Gloas at the consensus layer, including enshrined proposer-builder separation and block-level access lists.

These changes aim to support greater Layer 1 throughput while keeping block validation practical for node operators. The gas accounting system also sees updates, with EIP-8037 increasing and separately metering state creation costs.

The Ethereum Foundation has confirmed that Prysm 7.2.0 and Teku 26.9.1 support the Glamsterdam fork on Sepolia, but only as a configured validator preference, not a network-wide result.
