Solana has reduced its blockchain slot time to 350 milliseconds, marking the first such adjustment since the network’s launch. The change, confirmed by the Solana Foundation’s vice president of technology, Jacob Creech, follows a proposal approved and merged in mid-May.
The current slot time averages 360 milliseconds, down from the network’s original 400-millisecond target, according to the Solana slot time explorer. The reduction aligns with a broader plan to improve latency and speed up transaction confirmations. Solana aims to further trim slot times in three additional 50-millisecond increments, targeting a final duration of 200 milliseconds.
All four planned reductions are slated for activation on mainnet via Agave v4.2, a validator client developed by Anza. The schedule remains tentative, with implementation dependent on network readiness. The proposal, designated SIMD-0525, was approved and merged on May 14, signaling formal support for the technical adjustment.
Creech, in a post on X, framed the milestone as a step toward greater efficiency, stating, “We’re in a new era of 350ms. Next stop, 300ms.”
