Base to Enhance Testing After Two Network Outages

Base, the Ethereum Layer 2 solution, has issued a report addressing two significant network outages that took place on June 25 and 26, resulting from a flaw in the sequencer's logic.

The outages saw the network halt operations, with the first episode lasting 116 minutes and the second 20 minutes. During these periods, new blocks were not produced, transactions went unrecorded, and users faced errors while trying to initiate new transactions. Importantly, the report reassured users that their funds remained secure throughout these disruptions.

Details of the Outages

The initial incident was triggered by a failed transaction that caused the sequencer to improperly save the system's internal state. This error led to an invalid block formation, which was subsequently rejected by other network nodes, stopping block production entirely. After a fix was implemented, a race condition during the sequencer's restart created synchronization issues among nodes, leading to the second, shorter outage.

Future Enhancements

In response to these outages, the Base team plans to implement robust stress testing and fuzzing techniques to better anticipate and handle unusual transaction scenarios. Moreover, they aim to enhance network monitoring and establish a graceful recovery mechanism to expedite the network's functionality following similar issues.

A notable development in February also saw Base transition from the Optimism tech stack to a proprietary unified network architecture.
