Base mainnet launches Denim upgrade, block interval reduced to 200 milliseconds

TechFlow news, November 6: According to The Block, Base's fourth standalone network upgrade, Denim, has gone live on mainnet. The network now produces a complete canonical block every 200 milliseconds, or 5 blocks per second.

This upgrade deprecates Flashblocks; applications that previously relied on this feature must migrate to standard block subscriptions. Denim also introduces BaseTime, enabling smart contracts to access millisecond-precision timestamps, while updating transfer restrictions and compliance controls for B20 tokens.
