Solana switches to Alpenglow on Oct 21; validators need 0.8 SOL
- —Alpenglow replaces TowerBFT with Votor and aggregated BLS signatures
- —Validators need Agave 4.3.2+, a BLS key and 0.8 SOL in the vote account
- —The 0.8 SOL is a fixed fee under the Validator Admission Ticket model
- —Target finality is 150 ms versus about 12.8 seconds today
Why it matters: The upgrade rewrites Solana's core consensus, and validators that miss the requirements may drop out of voting once the new rules take effect.
