Solana Cuts Block Time to 350ms for First Time

This is a throughput story, not a fees story. Faster blocks matter most to latency-sensitive on-chain activity — trading, payments, consumer apps — where Solana already competes for order-flow against other high-performance chains. The open question is whether the gain holds under sustained load rather than in a milestone moment, and whether applications actually re-architect around sub-second finality or simply absorb it as headroom.
