#SolanaCutsTargetSlotTimeTo250ms Solana has cut its target slot time from 300ms to 250ms, making blocks arrive nearly 17% faster without increasing overall transaction capacity .
The change is the third stage of SIMD-0525, a four-step plan gradually reducing slot times from the original 400ms toward a final target of 200ms . Validators still lead for four consecutive slots, so their control window shrinks from 1.2 seconds to 1 second .
Because epochs are fixed at 432,000 slots, the expected epoch duration drops from roughly 36 hours to 30 hours . The final 200ms stage has no mainnet date yet .$SOL
