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

Solana's Alpenglow upgrade, launching Wednesday, aims to reduce transaction finality to 150 milliseconds from six seconds by moving validator voting off-chain. The upgrade is expected to cut validator costs by 60%. The network underwent multiple test restarts and a failed migration before the mainnet launch. According to Robin Nordnes, CEO of Raiku, the upgrade will not impact actual trading volume.
