Solana’s Alpenglow, its biggest network overhaul since 2020, goes live Wednesday

Solana's Alpenglow upgrade, its largest network overhaul since 2020, goes live Wednesday, replacing the existing voting system with a design targeting roughly 150-millisecond finality. The rollout follows months of testing that included a failed migration and rollback, which adds execution risk to the launch. Traders will watch whether the upgrade delivers the promised speed improvements without disruption, since a smooth launch could strengthen Solana's competitive position while any repeat of the earlier failure would weigh on confidence.
