Ethereum node operators can now test the upcoming Glamsterdam upgrade on a public permissionless network that launched on August 13. The test network will remain available until the Glamsterdam upgrade reaches mainnet. The upgrade introduces EIP‑7732, which separates consensus‑block validation from execution‑payload validation and adds a Payload Timeliness Committee. This design extends the critical path, giving proposers six seconds to validate a payload and other validators nine seconds. Platåberget, maintained by ethPandaOps, provides client‑pair images, checkpoint syncing resources, deposit tools, and utilities for testing builder and fork‑choice behavior. Application developers are directed to Sepolia for decentralized app and smart‑contract testing. Gas cost analysis shows a plain ETH transfer requires approximately 18,000 gas on the test network, while the current reference case for an existing externally owned account totals 21,000 gas, indicating that lower fees have not yet been confirmed. Additional proposals, including EIP‑7928, add block‑level access lists that map accounts and storage locations touched by a block, and EIP‑2780, 8037 and 8038 remain in review. The state‑creation proposal charges 183,600 state gas for creating a new account, and a storage write cost rises from 2,800 to 10,000. Operators must verify builder onboarding, payload timing, and fork‑choice behavior under the new division of duties, as well as continue basic uptime checks. The public test network will stay active until Glamsterdam reaches mainnet, after which the upgrade is expected to be deployed.
