Sep 28 is being treated like Solana’s Alpenglow mainnet launch. It isn’t.
Anza’s corrected Agave v4.3 schedule says today is when general mainnet feature activation resumes. Alpenglow itself has been rolling out testnet-first, then devnet, with mainnet-beta coming only after an observation period.
That distinction matters because the upgrade is a big one: #Alpenglow replaces TowerBFT with Votor and targets roughly 150ms finality versus about 12.8 seconds today.
But installing the software, resuming feature gates and actually migrating consensus are three different milestones.
So a “$SOL gets 150ms finality today” headline is ahead of the evidence.
The useful confirmation isn’t the calendar. It’s cluster state showing Alpenglow has actually migrated on mainnet-beta.
Until then, Sep 28 is a rollout milestone, not the finish line.
