Plat\u00e5berget focuses on client software, staking setups, builders, and infrastructure.<\/p>\n<h2>What Ethereum operators need to test<\/h2>\n<p>The <a href=\"https:\/\/ethereum.org\/roadmap\/glamsterdam\/\">Glamsterdam roadmap<\/a> says node operators will need compatible releases for both sides of an <a href=\"https:\/\/cryptoslate.com\/coins\/ethereum\/\">Ethereum<\/a> node.<\/p>\n<p>The execution client processes transactions, while the consensus client tracks validators and agrees on the chain. Plat\u00e5berget provides client-pair images and resources for checkpoint syncing and deposits, plus tools for testing builder and fork-choice behavior under load.<\/p>\n<p>The largest architectural change is <a href=\"https:\/\/eips.ethereum.org\/EIPS\/eip-7732\">EIP-7732<\/a>, or enshrined proposer-builder separation. The Review-stage proposal separates consensus-block validation from execution-payload validation, adds staked builders and creates a Payload Timeliness Committee to report whether a builder revealed its payload on time.<\/p>\n<p>Ethereum says the design expands the roughly two-second critical path: the next proposer gets six seconds to validate a payload, while other validators get nine seconds. Operators need to exercise builder onboarding, payload timing, and fork-choice behavior under the new division of duties alongside basic uptime checks.<\/p>\n<figure id=\"attachment_556598\" aria-describedby=\"caption-attachment-556598\" style=\"width: 720px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/cryptoslate.com\/wp-content\/uploads\/2026\/08\/exec-cfefd068-2ccd-4ed9-9eef-74ece56282cd.png\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-556598\" src=\"https:\/\/cryptoslate.com\/wp-content\/uploads\/2026\/08\/exec-cfefd068-2ccd-4ed9-9eef-74ece56282cd.png\" alt=\"Infographic showing Ethereum's Plat\u00e5berget\u2019s two-client Glamsterdam upgrade path, ePBS timing from about two seconds to six and nine seconds, and six operator test areas.\" width=\"720\" height=\"1080\" srcset=\"https:\/\/cryptoslate.com\/wp-content\/uploads\/2026\/08\/exec-cfefd068-2ccd-4ed9-9eef-74ece56282cd.png 1024w, https:\/\/cryptoslate.com\/wp-content\/uploads\/2026\/08\/exec-cfefd068-2ccd-4ed9-9eef-74ece56282cd-200x300.png 200w, https:\/\/cryptoslate.com\/wp-content\/uploads\/2026\/08\/exec-cfefd068-2ccd-4ed9-9eef-74ece56282cd-683x1024.png 683w, https:\/\/cryptoslate.com\/wp-content\/uploads\/2026\/08\/exec-cfefd068-2ccd-4ed9-9eef-74ece56282cd-768x1152.png 768w\" sizes=\"(max-width: 720px) 100vw, 720px\" \/><\/a><figcaption id=\"caption-attachment-556598\" class=\"wp-caption-text\">A diagram outlines the Glamsterdam operator test, covering two-client upgrades, ePBS validation timing, and key validator testing areas.<\/figcaption><\/figure>\n\n<div class=\"cs-article-embed\">\n    <a href=\"https:\/\/cryptoslate.com\/ethereums-2026-roadmap-includes-a-validator-risk-that-is-bigger-than-you-think-to-deliver-the-massive-throughput-gains\/\" class=\"cs-article-embed__link\">\n        <div class=\"cs-article-embed__body\">\n            <span class=\"cs-article-embed__related-reading\">Related Reading<\/span>\n            <h3 class=\"cs-article-embed__title\">Ethereum\u2019s 2026 roadmap includes this validator risk that's bigger than you think<\/h3>\n        <\/div>\n        <span class=\"cs-article-embed__arrow\" aria-hidden=\"true\">\n            <i class=\"fa-light fa-arrow-up-right\"><\/i>\n        <\/span>\n    <\/a>\n<\/div>\n\n<p>Review-stage <a href=\"https:\/\/eips.ethereum.org\/EIPS\/eip-7928\">EIP-7928<\/a> adds block-level access lists that record the accounts and storage locations touched by a block.
