The Layer 2 network transitions to five canonical blocks per second, sun-setting Flashblocks while developers investigate initial transaction inclusion delays.
Key point 1 of 3
01
Base activated its Denim upgrade on Nov. 5 at 18:00 UTC, accelerating canonical block production from two seconds to 200 milliseconds.
Key point 2 of 3
02
Denim discontinues Flashblocks, requiring downstream applications to migrate to canonical sub-second block and RPC streams.
Key point 3 of 3
03
Shortly following activation, network operators identified periodic transaction inclusion delays that produced an elevated rate of empty blocks.
Context
Base previously relied on two-second canonical blocks paired with Flashblocks for incremental execution updates before executing Denim to formalize sub-second canonical blocks.
Why it matters
Decentralized applications using block counts for timelocks, governance windows, or rate limits run ten times faster in wall-clock terms unless tuned or upgraded.
What to watch
Resolution of the sequencer transaction inclusion delays and empty-block rates being tracked on status.base.org.
