Solana cuts mainnet slot time to 300ms, cautious on 200ms move
- —Mainnet slot time cut from 400ms to 300ms, with 350ms and 300ms stages live
- —250ms and 200ms stages run on devnet and testnet, no mainnet dates set
- —Validator vote latency has grown, most notably for nodes in Asia and South America
- —Alpenglow, targeting ~150ms finality, is expected in Q3 2026 with Agave 4.3
Why it matters: Faster slot times speed up transaction confirmation, but rising vote latency could slow the shift to 200ms and the Alpenglow upgrade.
