Solana cuts blockchain slot time to 350 milliseconds

Latest NewsPublishedAug 21, 2026

Solana reduced its slot time for the first time since genesis as it works toward a 200-millisecond target aimed at reducing network latency.

Solana reduced its slot time to 350 milliseconds, marking the first such reduction since the inception of the network, as reported by the Solana Foundation’s vice president of technology, Jacob Creech.

“We’re in a new era of 350ms. Next stop, 300ms,” Creech stated in a Friday X post.

Average slot times on Solana stood at 360ms at press time, down from the network’s original 400ms target, as reported by the Solana slot time explorer.

In June, the Solana Foundation shared plans to reduce slot times from 400ms to 200ms, arguing that it would improve latency and accelerate confirmations on the blockchain network. Three further 50ms reductions are planned.

All four stages are targeted for mainnet activation in Agave v4.2, a validator client developed by Anza, though the schedule is tentative.

SIMD-0525, the proposal establishing the shorter slot times, was approved and merged on May 14.
