The page says the upgrade is designed to bring 150ms confirmation times to Solana, a sharp cut from the current finality window.<\/p>\n<p>The same Solana update says Alpenglow would remove Proof of History and on-chain vote transactions. That change is meant to simplify how the network agrees on blocks while reducing confirmation times and improving reliability.<\/p>\n<p>Moreover, earlier market background noted that Alpenglow uses direct messaging, signature aggregation, and off-chain validator voting. The design centers on Votor, a lightweight voting system that can finalize blocks in one or two rounds depending on validator support.<\/p>\n<p>The proposal also includes a Validator Admission Ticket, or VAT. Solana\u2019s own upgrade page says VAT is a 1.6 SOL fee that validators must pay to enter the consensus set each epoch. The change is tied to the removal of vote transactions from blocks.<\/p>\n<h2 class=\"wp-block-heading\"><strong>Solana upgrade race continues<\/strong><\/h2>\n<p>Earlier reports on crypto.news said Alpenglow could reduce median block finality to about 150 milliseconds and as low as 100 milliseconds under strong conditions. The same report said the upgrade could bring Solana\u2019s response times closer to Web2 infrastructure.<\/p>\n<p>Another background report said Solana validators had voted on SIMD-0326, the proposal tied to Alpenglow, in 2025. That report said the proposal aimed to replace TowerBFT with a faster and simpler system using off-chain voting.<\/p>\n<p>Meanwhile, Solana (SOL)\u00a0 traded near $97 after the testing update, with an intraday range between $94 and $98, according to crypto.news data. The price move showed limited short-term market reaction while Alpenglow remains in testing and has not yet reached mainnet.<\/p>\n<p>    <!-- .cn-block-related-link --><\/p><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Solana\u2019s Alpenglow upgrade has entered community validator testing, moving one of the network\u2019s largest technical changes closer to mainnet.\u00a0 Summary Anza says Alpenglow is now live on a community test&hellip;<\/p>\n","protected":false},"author":1,"featured_media":150,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-28302","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-cryptocurrency"],"_links":{"self":[{"href":"https:\/\/bitunikey.com\/news\/wp-json\/wp\/v2\/posts\/28302","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/bitunikey.com\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/bitunikey.com\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/bitunikey.com\/news\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/bitunikey.com\/news\/wp-json\/wp\/v2\/comments?post=28302"}],"version-history":[{"count":1,"href":"https:\/\/bitunikey.com\/news\/wp-json\/wp\/v2\/posts\/28302\/revisions"}],"predecessor-version":[{"id":28303,"href":"https:\/\/bitunikey.com\/news\/wp-json\/wp\/v2\/posts\/28302\/revisions\/28303"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/bitunikey.com\/news\/wp-json\/wp\/v2\/media\/150"}],"wp:attachment":[{"href":"https:\/\/bitunikey.com\/news\/wp-json\/wp\/v2\/media?parent=28302"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/bitunikey.com\/news\/wp-json\/wp\/v2\/categories?post=28302"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/bitunikey.com\/news\/wp-json\/wp\/v2\/tags?post=28302"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
