Ethereum Enables Public Network Test for Glamsterdam Upgrade

Ethereum has enabled a public network to practice the coordination between the execution client and the consensus client for the Glamsterdam upgrade. Platåberget went live on August 13, with validators open and permissionless, and is expected to remain available until the update reaches the mainnet. This environment is created for node operators, validators, builders, and infrastructure teams to check the collaborative operation of various components. The official recommendation is to use Sepolia for testing applications, smart contracts, and other uses of the EVM. One of the core changes is EIP-7732, which separates consensus block validation from execution payload validation, introducing staked builders and a committee responsible for informing whether the payload is disclosed within the deadline. The design extends the critical path to about 2 seconds, allowing the next proposer 6 seconds to validate the payload, while other validators receive 9 seconds, changing the testing of builders, payload timing, and fork selection. Another proposed test is EIP-7928, which adds block-level access lists to record accounts and storage locations touched by blocks, potentially aiding clients in parallelizing disk reads, transaction validation, and state computation. Teams need to review estimates and parameters related to gas and storage, including fixed gas for sub-calls, refund-dependent processes, and workloads for creating accounts or writing to storage, such as minting, airdrops, and factory contracts.
