Solana: Alpenglow Upgrade Activates With Finality and Performance Goals - 28 Sep 2026

Solana's Alpenglow upgrade is scheduled to activate on September 28, introducing a consensus-level change aimed at improving network performance and finality. The activation targets faster confirmation of transactions across the network, and its rollout represents one of the most substantial protocol changes Solana has scheduled to date.Because Alpenglow operates at the consensus layer, its effects extend to how quickly blocks reach finality, a property that influences the experience of applications built on Solana. Traders may reposition around SOL ahead of the activation date, since the outcome could shape the network's competitive standing against other high-throughput chains.Actual gains will depend on how the upgraded consensus performs under live network load after September 28, so early post-activation metrics will be the practical test of the upgrade's stated targets.Daily Crypto News1️⃣ Bitcoin stalls below $78KBTC is struggling to regain momentum as market activity cools, with Bitcoin’s ADX falling to 12 signaling weak trend strength.2️⃣ Ethereum ETFs see fresh inflowsSpot ETH ETFs opened September with positive net flows, giving…
