Base, a Layer 2 blockchain network, experienced a second disruption in two days on Friday, briefly halting block production before services were restored, according to its official status page.
The incident began at 15:33 UTC, with block production resuming by 16:11 UTC after node operators restarted their systems. The cause of the outage has not yet been disclosed.
Second outage follows earlier disruption
The interruption closely followed a longer outage on Thursday, when the network stopped processing blocks for nearly two hours. That issue was traced to an invalid block that caused the sequencer to fail at block 47,806,542, temporarily freezing transactions and some withdrawals.
While user funds remained safe, the halt disrupted normal activity across the network.
Friday’s outage showed similar technical signs, prompting developers to again instruct node operators to restart Base Mainnet nodes to restore synchronization.
Reliance on single sequencer raises concerns
The back-to-back disruptions have highlighted a structural weakness in Base’s design, particularly its reliance on a single sequencer to order and produce blocks. When that component failed, the entire network stopped functioning.
Base creator Jesse Pollak acknowledged the severity of the issue, noting that while funds were not at risk, outages are unacceptable for a system aiming to support global financial activity. The need for manual intervention to restart nodes further exposed operational fragility.
The incident also echoed a shorter outage recorded in August of the previous year, raising questions about long-term resilience.
Beryl upgrade launches despite instability
The outages occurred around the rollout of the Beryl upgrade, a scheduled software update that went live later on Thursday at 20:00 UTC. The upgrade introduces the B20 token standard along with improvements to transaction finality.
Unlike traditional token standards, B20 is embedded directly into the blockchain through a Rust precompile, a design intended to reduce costs and improve efficiency for issuing assets such as stablecoins and tokenized real-world assets.
Focus shifts to adoption and network activity
Attention is now turning to a forthcoming post-mortem report expected to explain the root cause of the failures and outline preventative measures.
Traders and developers will also be watching adoption of the B20 standard as a key measure of the upgrade’s success, particularly for compliant financial products that require features like transfer controls and asset freezing.
Network activity will provide further signals about sentiment following the disruptions. As of June 22, 2026, Base reported 6.1 million monthly active users and $4.5 million in fees over the previous 30 days. Any sustained decline in transactions or the network’s $12.2 billion in total value locked could indicate weakening confidence.
