Solana Cuts Slot Time to 350ms in First Reduction Since Genesis

Solana has cut its blockchain slot time to 350 milliseconds, the first reduction of its kind since the network’s inception, according to Solana Foundation vice president of technology Jacob Creech.

The change is the opening step in a broader effort to drive the network’s original 400-millisecond slot target down to 200 milliseconds, as reported by Cointelegraph.

First reduction since genesis Creech confirmed the milestone in a post on X, writing, “We’re in a new era of 350ms. Next stop, 300ms.” The adjustment marks the first time Solana has lowered its slot time since the blockchain launched.

For a network that has treated speed and low-latency execution as core design principles since genesis, the move carries both technical and symbolic weight, signaling that the foundation sees room to push performance further even after years of operation.
