Ethereum Layer 2 community Base briefly paused block manufacturing early Monday after practically two years of regular operation.
Base — Coinbase’s Layer 2 community constructed on Ethereum — suffered a quick outage early Monday morning, breaking an extended stretch of practically uninterrupted uptime because the community went reside in 2023.
The community halted block manufacturing at 06:15 UTC on Aug. 5, 2025, per knowledge from the Base Standing web page. The outage lasted roughly 29 minutes earlier than restoration was confirmed at 06:44 UTC.
The community’s standing web page flagged the problem as an “unsafe head delay.” As of press time, the web page states that the “problem’s been recognized and stuck, we’re now monitoring to make sure nothing else comes up.”
The outage occurred simply weeks after Base launched a brand new function that lets on-chain apps present transaction statuses virtually immediately to enhance responsiveness. Known as Flashblocks and constructed by Flashbots, the function makes use of “preconfirmation blocks,” that are small sub-blocks created each 200 milliseconds by the block builder.
It’s not clear if the replace is related to the outage. Coinbase didn’t instantly reply to The Defiant’s request for remark.
The newest incident is Base’s second main technical outage. The primary occurred on Sept. 5, 2023, when block manufacturing paused for about 43 to 45 minutes. Engineers later revealed in an X submit that the problem was attributable to inside infrastructure “requiring a refresh” and confirmed that no funds have been in danger.
On the time, Matt Willemsen, director of analysis at Collective Shift, an Australian crypto schooling platform, identified in an X submit that Ethereum-based Layer 2 chains differ from Ethereum mainnet, which is “extra battle-tested and includes fewer belief assumptions.”
