Ethereum (BITSTAMP:ETHUSD) developer teams are setting up the final testnet phase for the upcoming Glamsterdam network upgrade. The update is scheduled to activate on the Hoodi testnet on October 26, 2026, raising the gas limit from 60 million to 200 million. This follows an earlier deployment on the Sepolia testnet on October 6.

The roughly 3.3-fold increase in the gas limit is designed to allow more computation and transactions to fit into each block. Glamsterdam also introduces Layer 1 scaling improvements, including enshrined proposer-builder separation, block-level access lists, and revised gas pricing models aimed at better matching execution costs and state growth. Ethereum traded down 1.07% today at $2,374.

Developers will announce the mainnet release date for Glamsterdam once client teams reach a decision. Looking further ahead, developers are preparing for the Hegota fork planned for 2027, which is expected to consider 23 Ethereum Improvement Proposals before the network transitions to advanced cryptographic features.
