Solana achieves historic blockchain slot time reduction to 350ms
In a first since its launch, Solana has successfully decreased its slot time, advancing toward an ambitious 200-millisecond goal designed to minimize network latency.

The Solana network has successfully lowered its slot time to 350 milliseconds, representing the first reduction of this kind since the blockchain's genesis, as confirmed by Jacob Creech, vice president of technology at the Solana Foundation.

Data from the Solana slot time explorer showed that average slot times on the network registered at 360ms at the time of publication, representing a decrease from the blockchain's initial 400ms benchmark.
The Solana Foundation announced its intention in June to decrease slot times from 400ms down to 200ms, contending that this change would enhance latency performance and speed up confirmations across the blockchain network. An additional three reductions of 50ms each remain on the roadmap.
Mainnet activation for all four phases is scheduled for implementation in Agave v4.2, a validator client created by Anza, although this timeline remains subject to change.
The proposal outlining the reduced slot times, SIMD-0525, received approval and was merged into the codebase on May 14.
