Base, a blockchain backed by cryptocurrency exchange Coinbase, has returned online after a nearly two-hour network outage caused by a consensus issue that halted block production.
Resist sent to X on the Thursday after the outage that the network’s blocks “are being produced normally and we have verified widespread recovery in the ecosystem.”
Database status page he said on Thursday at 16:03 UTC was investigating “unhealthy” block production. At 17:21 UTC, the team said they had “isolated a consensus issue that caused an incorrect block to be sequenced. This prevented the creation of new blocks.”
Base said in an update just before 18:00 UTC that it had “recovered healthy block building” and that its ecosystem-wide infrastructure was able to synchronize, adding that it had identified the problem and would investigate the root cause and provide a full postmortem.
The outage was a sporadic outage of a core blockchain like Base, Ethereum’s most widely used Layer 2 network, which last experienced a major outage in August 2025 when it was down for 33 minutes. According to to the status page.

Base creator Jesse Pollack sent to X that all funds on the network are unthreatening, “but retention is not okay and we will use this to further refine the database as a 24/7 global finance platform.”

The outage appeared to occur separately and just a few hours before the Base update, named Beryl, was scheduled for 18:00 UTC and completed two hours later at 20:00 UTC.
The update aimed to reduce withdrawal delays and introduce a modern token standard for real assets and stablecoins.
Sui’s Layer 1 blockchain experienced two outage periods in May, each of which resulted in a momentary halt to block production. Sui later said the outage was due to a network upgrade, which she knew had a low probability of stopping work.
