Base Activates Denim Upgrade, Cutting Block Times to 0.2 Seconds

Speed alone is the headline, but the practical consequence is that block-based assumptions embedded across Base apps — timers, auctions, oracle refresh cycles, keeper logic — may no longer behave as their designers intended.

Whether the faster cadence translates into meaningfully different onchain activity, or simply compresses the same throughput into tighter intervals, is the open question worth watching.
