- Alpenglow upgrade set for October 21 at 14:50 UTC
- Transaction aims to reduce finality from 12.8s to milliseconds
- Validators will pay fixed fee of 0.8 SOL instead of 1.1 SOL daily
- Vote transactions will be removed from blocks
Multiple outlets, including Crypto Economy and CoinDesk, confirm that the Alpenglow upgrade is scheduled for October 21 at 14:50 UTC. Both outlets agree that the upgrade aims to reduce transaction finality times from 12.8 seconds to milliseconds and will replace the existing validator voting system. However, CoinDesk emphasizes that the change could significantly impact headline transaction counts even if user activity remains stable, a detail not highlighted by Crypto Economy.
Solana has announced the Alpenglow upgrade, scheduled for October 21 at 14:50 UTC, according to technical planning by Anza. The upgrade is designed to significantly reduce transaction finality times, aiming to bring them down from 12.8 seconds to under one second.
The mechanism behind this improvement involves replacing Solana's existing validator voting system. This change will remove vote transactions from blocks, which could lead to a sharp change in headline transaction counts even if user activity remains constant.
Validators will see a change in their cost structure as part of the upgrade. Currently, validators incur a daily cost of 1.1 SOL, but this will be replaced with a fixed fee of 0.8 SOL per day. This change could impact the economics of running a validator on the Solana network.
The upgrade comes at a time when Solana's transaction speed and efficiency are under scrutiny. The blockchain has been competing with other high-performance blockchains, and this upgrade could enhance its competitiveness by significantly improving transaction finality.
In the current market context, Solana (SOL) is trading at $107.66, down 0.20% in the last 24 hours and 8.72% over the past week. The overall crypto market cap stands at $2.89 trillion, with

The chart plots SOL's price: grey is the move before this brief published, the vertical dashed line marks the moment it published, the horizontal dashed line is the price then, and the coloured area is the move since — from Token Times's market data (daily resolution). It shows what happened after the news, not that the news caused it; many factors move prices. Not financial advice.
At today's peer-to-peer rate, 1 SOL ≈ ₹11,163.23 (about $107.03), down 1.2% over 24 hours. The rupee itself trades about 9.4% above the official rate on the P2P market, so a Indian buyer's effective cost differs from the headline dollar price.
