Solana’s Alpenglow upgrade targets October 21 for 150ms finality

Solana's Alpenglow upgrade is targeting an October 21 launch, aiming to reduce transaction finality to 150 milliseconds. Faster finality would improve network efficiency and could strengthen Solana's competitive position against other layer-1 blockchains. Traders may watch the upgrade timeline as a catalyst for SOL sentiment, though the actual market impact depends on successful implementation.
