The upcoming Alpenglow upgrade targets a dramatic reduction in transaction finality from roughly 12.8 seconds to about 150 milliseconds.The upgrade will make reaching cryptographic finality (the point at which the network has reached sufficient consensus) dramatically faster. The change could arrive as soon as September, and Solana's finality is on track to fall from 12.8 seconds to 150 milliseconds and make transactions \"feel almost instant.\" Solana's official documentation, however, currently places the Alpenglow rollout in the third quarter of 2026. A recent Solana Foundation update says the upgrade is expected to activate through Agave 4.3, which is targeted for October. The exact September date therefore should not be treated as confirmed.Finality is not the same as confirmationThe distinction is crucial to understanding why a 150ms finality target matters.When a Solana transaction is submitted, users can already receive confirmation very quickly. Solana's current slot time has also been reduced as part of a separate upgrade, with the network moving from 400ms slots toward 200ms slots. A transaction therefore does not normally leave a user staring at a screen for 12.8 seconds before seeing an indication that it succeeded.A transaction can be included in a block and viewed as confirmed while the network has not yet reached its strongest level of consensus about that block. In an extreme situation, the chain could reorganize and an earlier state could be rolled back. Finality is the mechanism that gives applications stronger certainty that the state they are observing will not subsequently be reversed.Under Solana's current TowerBFT consensus, that stronger finality can take roughly 12.8 seconds. Alpenglow's goal is to compress that process into roughly 150 milliseconds.Responding to the discussion about faster finality,  Solana co-founder Anatoly Yakovenko has argued that finality is \"really only important at the cash register.\" Imagine buying a product with cryptocurrency. A merchant may be willing to accept a transaction after a fast confirmation, but for larger-value payments it may want much stronger assurance that the payment cannot disappear from the canonical chain.However, for an ordinary Solana user, the change may not feel as dramatic as the raw numbers indicate.","kind":"highlight","is_publish_news":true,"is_publish_highlight":false,"is_publish_live":false,"is_publish_wemedia":false,"editions":null,"column":"","sentiment":"0","news_tag":"","news_rank":0,"isVideo":false,"video":null,"symbols":[],"gpt_button":0,"need_auth":false,"need_login_tip":false,"code":"91000000","status":"200"},"commentList":[],"isCommentEnd":true,"newsSizeData":{"likeSize":0,"commentSize":0,"repostSize":0,"favoriteSize":0,"likeStatus":false,"favoriteStatus":false},"APP":{"userAgent":"Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; ClaudeBot/1.0; +claudebot@anthropic.com)","isDev":false,"isTTM":true,"isLaohu8Offline":false,"tenantId":"TBGLOBAL","deviceId":"web-server-community-laohu8-v3","version":"4.47.1","shortVersion":"4.47.1","platform":"web","vendor":"web","appName":"ttm","isIOS":false,"isAndroid":false,"isTiger":false,"isTHS":false,"isWeiXin":false,"isWeiXinMini":false,"isWeiBo":false,"isQQ":false,"isBaiduSwan":false,"isBaiduBox":false,"isDingTalk":false,"isToutiao":false,"isOnePlus":false,"isHuaWei":false,"isXiaomi":false,"isXiaomiWebView":false,"isOppo":false,"isVivo":false,"isSamsung":false,"isMobile":false},"href":"/m/news/2659687146","isCrawlerRequest":true}
