Solana is finalizing a major mainnet upgrade to cut its target block time (slot time) from 250 milliseconds to 200 milliseconds. The final phase of this rollout is scheduled to activate at epoch 1053 on Friday, October 9, 2026 (expected around 15:00 UTC / 11 a.m. ET). [1, 2, 3]
This implementation completes a structured four-stage latency reduction roadmap established under technical proposal SIMD-0525, which successfully reduced block times down from the original 400-millisecond baseline since August 2026. [1, 2, 3]
