Anza Sets Oct. 21 for Solana’s Alpenglow Mainnet Upgrade

The headline number is the finality target, but the operational burden is the real story: a consensus-layer change forces validators and block-data providers to upgrade software on a fixed schedule, and coordination risk — not the technical spec — is what determines whether the switch is clean. Anything reading Solana's finality as an input to latency-sensitive RWA or trading infrastructure has a concrete date to work against now. Whether the ecosystem migrates without disruption, and how quickly downstream data services reflect the new finality regime, is the open question.
