Solana Cuts Slot Time to 350 Milliseconds in Path Towards 200 ms

Solana has taken a significant step towards faster transaction confirmations by activating its mainnet feature that cuts the target slot time from 400 milliseconds to 350 milliseconds. This is the network's first slot-time reduction since its inception, and it marks the beginning of an epoch-by-epoch path towards 200 milliseconds.

The change shortens the window for leaders to complete blocks and gives users faster transaction confirmations. For validators, this shift starts a staged transition rather than an immediate jump to the planned 200-millisecond endpoint. Each additional 50-millisecond reduction will activate through a separate feature gate in a later epoch, allowing the network to pause if block skip rates climb.

Jacob Creech, vice president of technology at the Solana Foundation, described the move as Solana's first slot-time reduction and said 300 milliseconds is the next target. The network has a planned sequence that moves from 400 milliseconds to 350, then 300, 250, and finally 200 milliseconds.
