Base cuts block time to 0.2 seconds with Denim upgrade

Coinbase's Base network cut its block time from two seconds to 0.2 seconds with its Denim upgrade, which took effect at 1 p.m. ET Thursday. That makes block production 10 times faster, meaning on-chain timers and applications that count blocks rather than minutes will now resolve far more quickly. Faster blocks can improve user experience and throughput on the layer-2, a competitive point against rival rollups, though the change matters more for developers than for near-term price action.
