According to Chinese blockchain journalist Wu Blockchain, the cryptocurrency exchange Coinbase‘s Layer 2 solution, Base, experienced a halt in block production on August 5, 2025, around 09:15 Turkish Standard Time (TSI). For about 19 minutes, no new blocks were added, causing network instability. The issue was identified using BaseScan and OKLink data. Due to the severity of the situation, teams promptly intervened to monitor network transactions, and normalcy was restored following their interventions.
Block Production Halt Affects Multiple Stakeholders
Thanks to the efforts of field engineers, block production on the Base main network, which had stopped at 09:15 TSI, resumed by 10:44 TSI. Initially, block height was stuck at 33,792,704, causing concern among investors and users. As a result, deposit, withdrawal, and Flashblock transactions on the network were completely suspended.
No official statement has yet been released regarding the cause of the block production halt. However, analyses suggest that a communication breakdown between producer nodes and validators was the root cause. Third-party monitoring tools triggered automatic alert mechanisms once the error was detected.
Issue Resolved Post-Intervention
The Base development team assigned a dedicated technical team to address the block production interruption based on real-time data. A comprehensive review of node software and synchronization protocols was carried out. Initial findings indicated that timestamp discrepancies in network nodes were a potential cause of the block production issue.
According to the announcement on the official status page, infrastructure teams restructured the complex synchronization packages. Following phased tests, block production on the network resumed. Post-update, the network’s performance is being closely monitored by teams to ensure stability.
