Solana shortens slot time to 250 milliseconds, with transaction capacity remaining unchanged.

According to CoinDesk, Solana has reduced the target slot time from 300 milliseconds to 250 milliseconds, boosting block production speed by nearly 17% and enabling applications to fetch on-chain states faster while shortening the transaction ordering window for validators. However, because the compute and data limits per slot are scaled down accordingly, the network’s overall transaction processing capacity remains largely unchanged. This adjustment will also accelerate block hash expiration and reduce the expected duration of each epoch from approximately 36 hours to 30 hours.
