Solana Speeds Up Block Times for First Time Since Launch

This is Solana's first change to its core block-timing parameter since genesis, which matters because it touches the network's base throughput rather than adding another layer or app on top. The practical effect falls on validators, who must keep pace with tighter slots, and on latency-sensitive users such as traders and on-chain applications. Whether the faster cadence holds under sustained load without degrading validator economics or reliability is the open question.
