Scheduled to run for several months, Plat\u00e5berget offers developers and validators a chance to prepare for significant changes to Ethereum\u2019s consensus and execution layers. The testnet&#8217;s transition to the Glamsterdam fork is set for August 20, 2026.<\/p>\n<p>The Glamsterdam upgrade introduces several breaking changes, including gas repricing, enshrined proposer-builder separation (ePBS), and block-level access lists. Developers are strongly encouraged to test their tools and infrastructure on Plat\u00e5berget, as the changes will impact wallets, indexers, gas estimators, and other applications reliant on Ethereum&#8217;s existing mechanics.<\/p>\n<h2>Key Changes in Glamsterdam<\/h2>\n<p>The Glamsterdam fork brings a range of new Ethereum Improvement Proposals (EIPs) aimed at enhancing network performance and scalability. Highlights include:<\/p>\n<ul>\n<li><strong>Enshrined Proposer-Builder Separation (EIP-7732):<\/strong> This shifts how blocks are built and validated, requiring updates to infrastructure that interacts with the block production pipeline.<\/li>\n<li><strong>Block-Level Access Lists (EIP-7928):<\/strong> Introduces a mechanism to track state changes, improving transparency and communication between execution-layer peers.<\/li>\n<li><strong>Gas Repricing (EIP-8007):<\/strong> Adjusts gas costs to target a ~200M gas floor, posing challenges for any tool that hardcodes gas limits.<\/li>\n<li><strong>Larger Contracts and Initcode (EIP-7954):<\/strong> Expands the maximum sizes for deployed contracts and initialization code, facilitating more complex applications.<\/li>\n<li><strong>Forward-Compatible Consensus Structures (EIP-7688):<\/strong> Prepares Ethereum for future upgrades.<\/li>\n<\/ul>\n<p>Specific attention is being drawn to gas repricing, which changes both block-wide and operation-specific gas costs. For example, transactions creating new accounts or deploying contracts will incur additional costs based on state gas dimensions, a departure from the flat 21,000 gas fee for basic ETH transfers. Developers relying on legacy assumptions must update their systems to avoid disruptions.<\/p>\n<h2>Testing Opportunities<\/h2>\n<p>Plat\u00e5berget aims to provide a stable testing ground for developers, validators, and infrastructure operators. Unlike previous short-lived devnets, Plat\u00e5berget will persist long enough to identify and address issues before the upgrade is rolled out to Ethereum\u2019s more durable testnets, Sepolia and Hoodi. Validators can join the network by depositing funds, and testnet ETH is available via a dedicated faucet.<\/p>\n<p>The Ethereum Foundation has also emphasized the importance of testing ePBS workflows, particularly for solo stakers, distributed validator technology (DVT) projects, and large-scale operators. Bugs and feedback can be submitted to the Ethereum R&amp;D Discord or GitHub repositories for consensus, execution, and builder specifications.<\/p>\n<h2>What\u2019s Next?<\/h2>\n<p>The feedback gathered during Plat\u00e5berget\u2019s operation will inform client updates and specifications. Following Plat\u00e5berget, Ethereum plans to launch a non-finality devnet to simulate edge-case scenarios in consensus. Once stable, the upgrade will proceed to Sepolia and Hoodi before reaching mainnet.<\/p>\n<p>For developers, this is a critical window to ensure their applications and tools are ready for the Glamsterdam fork. Key resources, including network settings, client releases, and the EIP tracker, are available through Ethereum\u2019s official channels.<\/p>\n<p>With the mainnet transition to Glamsterdam on the horizon, Ethereum is laying the groundwork for a smoother and more scalable blockchain future. Developers and validators are encouraged to join Plat\u00e5berget now and contribute to the testing process.<\/p>\n<p><span><i>Image source: Shutterstock<\/i><\/span> <!-- Divider --> <!-- Bookmark button --> <!-- Bookmark button END --> <!-- Author info END --> <!-- Divider --> <a href=\"https:\/\/blockchain.news\/\">Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Darius Baruo Aug 17, 2026 10:03 Ethereum debuts Plat\u00e5berget testnet for Glamsterdam upgrade testing.
