Base Sets November 5 Denim Activation as Apps Prepare for Native 200ms Blocks

Dextape brief

By Dextape Desk · November 2, 2026

Base has set November 5 at 18:00 UTC as the mainnet activation time for its Denim upgrade. According to the network's status notice, mainnet should stay operational during the Denim maintenance window, and node operators must apply the mandated version ahead of the switch. The headline change is native block production every 200 milliseconds, up from a single canonical block per two-second interval, which Base's documentation says replaces Flashblocks. Apps that follow the older stream must switch to canonical block feeds and RPC feeds. Denim also adds millisecond-aware time data alongside existing seconds fields, so software assuming each block brings a new whole-second timestamp could misorder records. The article notes that faster block observation does not by itself establish final settlement. Denim remains scheduled work that has not yet occurred.

Why it matters: Faster block production changes how often applications process data, and timing fields must be read carefully to avoid misordered records.
