Ethereum’s next upgrade turns a 2-second block bottleneck into a roughly 9-second window

Ethereum node operators now have an active public network for rehearsing Glamsterdam’s coordinated execution- and consensus-client upgrade. Platåberget has an open, permissionless validator set, turning the upgrade into a practical test of whether client pairs, validators, builders, and supporting infrastructure continue to work together.

The ethPandaOps-maintained network launched Aug. 13 and is expected to remain available until Glamsterdam reaches mainnet.

For application work, the official page directs decentralized application, smart contract, and other EVM testing to Sepolia. Platåberget focuses on client software, staking setups, builders, and infrastructure.

What Ethereum operators need to test

The Glamsterdam roadmap says node operators will need compatible releases for both sides of an Ethereum node.

The execution client processes transactions, while the consensus client tracks validators and agrees on the chain. Platåberget provides client-pair images and resources for checkpoint syncing and deposits, plus tools for testing builder and fork-choice behavior under load.
