Solana’s Alpenglow upgrade aims to cut finality time to 150 milliseconds

Solana's proposed Alpenglow upgrade targets cutting transaction finality time to roughly 150 milliseconds, a significant speed improvement over current performance. Faster finality could strengthen Solana's appeal to institutional users and high-frequency applications, potentially boosting adoption and network activity. Traders may view the upgrade as a positive competitive differentiator versus other layer-1 chains, though the story is a development roadmap item rather than a live protocol change.
