Ethereum Foundation launches Platåberget testnet for Glamsterdam to upgrade early testing

Comparatively, the Ethereum Foundation Protocol DevOps team announced the launch of the Platåberget testnet as an early public testing environment for the Glamsterdam (Gloas+ Amsterdam) upgrade. The testnet is open to the community and is scheduled to run for several months to provide developers with a stable testing platform to find and fix issues before upgrading to long-term test networks such as Sepolia and Hoodi. The Glamsterdam hard fork is scheduled to be activated on this testnet on August 20.

The Glamsterdam upgrade covers a number of major changes in the consensus layer and execution layer, including built-in proposer-builder separation (ePbS), block-level access lists (BARs), gas repricing targeting approximately 200 million gas, increasing the maximum contract deployment size from 24 KiB to 64 KiB, increasing the initcode limit from 48 KiB to 128 KiB, and forward-compatible consensus data structures. The relevant EIPs are summarized in meta EIP-7773. Gas repricing will affect wallets, indexers, and gas estimation tools. Any tool with a hardcoded maximum gas limit will need to be updated; EIP-8037 also introduces an independent state gas dimension, and new accounts created or written to a new storage slot will be billed based on status bytes.

The Platåberget validator set is small and allows the public to join, and supports submitting validator or builder deposits through the Dora browser. The testnet provides one-click addition of network, faucet, and client image resources. The community can provide feedback on the Ethereum R&D Discord and related specification repositories.
