While <a class=\"chakra-link css-vezwxf\" href=\"https:\/\/blog.ethereum.org\/2025\/03\/05\/sepolia-pectra-incident\">Sepolia&#8217;s recovery<\/a> was straightforward and the network has since fully recovered, Holesky experienced extensive inactivity leaks as part of its recovery mechanism.<\/p>\n<p class=\"chakra-text css-gi02ar\">The Holesky network has since then finalized, but the exited validators would take approximately one year to fully be removed from the validator set (<a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-vezwxf\" href=\"https:\/\/hackmd.io\/@mikeneuder\/eli5-ethereum-validator-exits\">\u00b9<\/a>). While stakers can test deposits, consolidations and all other Pectra features, the size of the exit queue prevents Holesky from being used to test the full validator lifecycle within a reasonable timeframe.<\/p>\n<p class=\"chakra-text css-gi02ar\"><strong>To address this, a new testnet has been launched: <a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-vezwxf\" href=\"https:\/\/hoodi.ethpandaops.io\/\">Hoodi<\/a>. It will activate the Pectra network upgrade at epoch 2048 (Wed. March 26, 2025 14:37:12 UTC).<\/strong> Client releases that support the Pectra upgrade on Hoodi are listed below.<\/p>\n<p class=\"chakra-text css-gi02ar\">Moving forward, staking operators and infrastructure providers should use Hoodi for validator testing. To allow time for the migration, the Holesky testnet will be supported until September 2025. Aside from validator exits, all other Pectra features can be tested on Holesky.<\/p>\n<h2 class=\"chakra-heading group css-1kpzc4q\" id=\"consensus-layer-pectra-hoodi-releases\" data-group=\"true\"><a class=\"chakra-link css-128fqrf\" aria-label=\"consensus layer pectra hoodi releases permalink\" href=\"#consensus-layer-pectra-hoodi-releases\"><svg viewbox=\"0 0 24 24\" focusable=\"false\" class=\"chakra-icon css-173jpr1\"><g fill=\"currentColor\"><path d=\"M10.458,18.374,7.721,21.11a2.853,2.853,0,0,1-3.942,0l-.892-.891a2.787,2.787,0,0,1,0-3.941l5.8-5.8a2.789,2.789,0,0,1,3.942,0l.893.892A1,1,0,0,0,14.94,9.952l-.893-.892a4.791,4.791,0,0,0-6.771,0l-5.8,5.8a4.787,4.787,0,0,0,0,6.77l.892.891a4.785,4.785,0,0,0,6.771,0l2.736-2.735a1,1,0,1,0-1.414-1.415Z\"\/><path d=\"M22.526,2.363l-.892-.892a4.8,4.8,0,0,0-6.77,0l-2.905,2.9a1,1,0,0,0,1.414,1.414l2.9-2.9a2.79,2.79,0,0,1,3.941,0l.893.893a2.786,2.786,0,0,1,0,3.942l-5.8,5.8a2.769,2.769,0,0,1-1.971.817h0a2.766,2.766,0,0,1-1.969-.816,1,1,0,1,0-1.415,1.412,4.751,4.751,0,0,0,3.384,1.4h0a4.752,4.752,0,0,0,3.385-1.4l5.8-5.8a4.786,4.786,0,0,0,0-6.771Z\"\/><\/g><\/svg><\/a>Consensus Layer Pectra Hoodi Releases<\/h2>\n<p class=\"chakra-text css-gi02ar\"><em class=\"chakra-text css-0\">When running a validator, both the Consensus Layer Beacon Node and Validator Client must be updated.<\/em><\/p>\n<p class=\"chakra-text css-gi02ar\">Note: Lodestar Hoodi users that run a validator client in multi-client setups should use <a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-vezwxf\" href=\"https:\/\/github.com\/ChainSafe\/lodestar\/releases\/tag\/v1.28.1\">v1.28.1<\/a>.<\/p>\n<h4 class=\"chakra-heading group css-qm6a1\" id=\"execution-layer-pectra-hoodi-releases\" data-group=\"true\"><a class=\"chakra-link css-128fqrf\" aria-label=\"execution layer pectra hoodi releases permalink\" href=\"#execution-layer-pectra-hoodi-releases\"><svg viewbox=\"0 0 24 24\" focusable=\"false\" class=\"chakra-icon css-173jpr1\"><g fill=\"currentColor\"><path d=\"M10.458,18.374,7.721,21.11a2.853,2.853,0,0,1-3.942,0l-.892-.891a2.787,2.787,0,0,1,0-3.941l5.8-5.8a2.789,2.789,0,0,1,3.942,0l.893.892A1,1,0,0,0,14.94,9.952l-.893-.892a4.791,4.791,0,0,0-6.771,0l-5.8,5.8a4.787,4.787,0,0,0,0,6.77l.892.891a4.785,4.785,0,0,0,6.771,0l2.736-2.735a1,1,0,1,0-1.414-1.415Z\"\/><path d=\"M22.526,2.363l-.892-.892a4.8,4.8,0,0,0-6.77,0l-2.905,2.9a1,1,0,0,0,1.414,1.414l2.9-2.9a2.79,2.79,0,0,1,3.941,0l.893.893a2.786,2.786,0,0,1,0,3.942l-5.8,5.8a2.769,2.769,0,0,1-1.971.817h0a2.766,2.766,0,0,1-1.969-.816,1,1,0,1,0-1.415,1.412,4.751,4.751,0,0,0,3.384,1.4h0a4.752,4.752,0,0,0,3.385-1.4l5.8-5.8a4.786,4.786,0,0,0,0-6.771Z\"\/><\/g><\/svg><\/a>Execution Layer Pectra Hoodi Releases<\/h4>\n<h2 class=\"chakra-heading group css-1kpzc4q\" id=\"summary-of-testnets-and-their-purpose\" data-group=\"true\"><a class=\"chakra-link css-128fqrf\" aria-label=\"summary of testnets and their purpose permalink\" href=\"#summary-of-testnets-and-their-purpose\"><svg viewbox=\"0 0 24 24\" focusable=\"false\" class=\"chakra-icon css-173jpr1\"><g fill=\"currentColor\"><path d=\"M10.458,18.374,7.721,21.11a2.853,2.853,0,0,1-3.942,0l-.892-.891a2.787,2.787,0,0,1,0-3.941l5.8-5.8a2.789,2.789,0,0,1,3.942,0l.893.892A1,1,0,0,0,14.94,9.952l-.893-.892a4.791,4.791,0,0,0-6.771,0l-5.8,5.8a4.787,4.787,0,0,0,0,6.77l.892.891a4.785,4.785,0,0,0,6.771,0l2.736-2.735a1,1,0,1,0-1.414-1.415Z\"\/><path d=\"M22.526,2.363l-.892-.892a4.8,4.8,0,0,0-6.77,0l-2.905,2.9a1,1,0,0,0,1.414,1.414l2.9-2.9a2.79,2.79,0,0,1,3.941,0l.893.893a2.786,2.786,0,0,1,0,3.942l-5.8,5.8a2.769,2.769,0,0,1-1.971.817h0a2.766,2.766,0,0,1-1.969-.816,1,1,0,1,0-1.415,1.412,4.751,4.751,0,0,0,3.384,1.4h0a4.752,4.752,0,0,0,3.385-1.4l5.8-5.8a4.786,4.786,0,0,0,0-6.771Z\"\/><\/g><\/svg><\/a>Summary of testnets and their purpose<\/h2>\n<p class=\"chakra-text css-gi02ar\">\n  <img decoding=\"async\" src=\"https:\/\/storage.googleapis.com\/ethereum-hackmd\/upload_b072937388453b68e3fb2533ad354e9c.png\" class=\"chakra-image css-hw6q2r\"\/>\n<\/p>\n<ul role=\"list\" class=\"css-1ars4k6\">\n<li class=\"css-0\"><strong>Holesky<\/strong>: Validators and Staking providers (Expected end of life 30th September, 2025).
