Solana's Alpenglow upgrade cuts block finality to around 150ms, speeding transaction certainty.

Solana activated its Alpenglow upgrade on October 21, 2026, replacing the old voting system with a certificate-based consensus to reduce block finality time from about 12.8 seconds to a target of 150 milliseconds. Early external measurements show a median finality of 404 milliseconds, a significant improvement that can speed up transaction settlement and improve user experience. The upgrade removes vote transactions from blocks, affecting transaction counts but not user fees or formats. While the upgrade enhances network finality, actual payment speed depends on wallet, exchange, and merchant policies. The next phase, Rotor, which will improve block distribution, has no set launch date yet.

Solana (SOL) trades at Rp1.800.000 on Pluang as of October 27, 2026, 16:51 WIB, showing a 1.87% decline over the past day. Despite the recent upgrade speeding up transaction finality, SOL’s price remains below its recent highs, with a market cap of Rp1.067,74 trillion and a 24-hour trading volume of Rp41,5 trillion. The typical hold time of 72 days and a nearly balanced buy-sell order activity (51% Buy vs. 49% Sell) indicate steady investor interest amid the network improvements.
