Solana has cut its mainnet slot time down to 350 milliseconds, marking the first step toward its ultimate 200ms goal. The official line is clear: this is about speeding up transaction confirmation, not boosting overall network throughput.
Solana has slashed its mainnet slot time to 350 milliseconds, the first step on the road toward its ultimate goal of 200ms.
Slot time is the core parameter that determines how often the Solana network produces blocks — the smaller the number, the faster transactions get packed into a block and confirmed. With this adjustment, the wait time between submitting a transaction and seeing it confirmed will shrink.
That said, this doesn't mean Solana's network can suddenly handle more transactions at once. The point of this change is to speed up confirmation, not to raise overall throughput — producing blocks more frequently doesn't mean each block can hold more data, nor does it raise the chain's overall transaction processing ceiling.
350ms is just a waypoint — 200ms is the real destination. No further timeline or technical details have been provided yet.
