United StatesSolana’s Alpenglow targets 150-millisecond finality, down from 12.8 seconds.

Finality means a payment cannot reverse, so exchanges and merchants would wait less.

Anza, which builds Solana’s core software, switched Alpenglow on for the developer network 25 September, a day after testnet.

Alpenglow’s speed target has not yet been sustained under live-market conditions.

Anza has not scheduled a mainnet launch.
