Solana reduced its target slot time from 300 milliseconds to 250 milliseconds, the third of four planned stages under SIMD-0525. The nearly 17% faster block cadence produces smaller, more frequent blocks rather than raising overall transaction capacity. The change can improve price-data freshness and responsiveness for latency-sensitive applications such as oracles and automated market makers. It also shortens the four-slot leader window to one second and reduces the expected epoch length from about 36 hours to about 30 hours. A final reduction to 200-millisecond slots remains contingent on stable block-skip rates and has no mainnet activation date.
