Not investment advice. Muhabbit scores how much a story may matter, not which way to trade.
Base has deployed its fourth standalone mainnet upgrade, Denim, cutting full canonical block times to 200 milliseconds, or five blocks per second. The upgrade disables Flashblocks, requiring applications that relied on the feature to migrate to standard block subscriptions. Denim also introduces BaseTime, giving smart contracts access to millisecond-precision timestamps, and updates transfer limits and compliance controls for B20 tokens. The change matters because faster blocks and finer-grained on-chain time can support more latency-sensitive applications on the Base network. What to watch next is how quickly dependent apps complete their migration off Flashblocks and whether the new timing and compliance features draw new usage.
