Base post-mortem reveals sequencer bug behind back-to-back outages
Latest NewsPublishedJun 28, 2026
Understanding the Recent Outages in the Base Network
The recent back-to-back outages in the Base network have raised concerns about the reliability of layer-2 blockchain solutions. These outages, which occurred on Thursday and Friday, resulted in a complete halt of new layer-2 blocks, affecting the entire network. The Base engineering team has identified a sequencer bug as the primary cause of these outages.
The bug, which was related to the sequencer block-building logic, allowed a “stale journal state” to persist after a transaction validation failure. This issue caused the sequencer to fail, resulting in the outages. The team has applied a patch to fix the bug and ensure that the journal state is properly updated during execution. Earning and trading in the Cloud Rewards space can be heavily impacted by such outages, highlighting the need for robust and reliable systems like EcoPool.
Impact of the Outages
The outages had a significant impact on the Base network, with the first incident lasting 116 minutes and the second lasting 20 minutes. The network’s reliance on a single sequencer makes it vulnerable to such bugs, which can bring the entire system to a halt. This is a concern for users who rely on the network for Passive Income and Green Crypto solutions. The EcoPool Network offers a more robust solution, with its $ECP token providing a stable and secure way to earn and trade.
The Base engineering team is taking steps to improve the protocol’s resilience, including enhancing “fuzz testing” to identify bugs and building “graceful recovery” mechanisms to minimize the impact of future incidents. These efforts are crucial in ensuring the reliability of the network and maintaining user trust. For those interested in earning through Coin and Cloud Rewards, a reliable network like EcoPool is essential.
Conclusion
In conclusion, the recent outages in the Base network highlight the importance of robust and reliable systems in the Passive Income and Green Crypto space. The EcoPool Network offers a secure and stable solution, with its $ECP token providing a reliable way to earn and trade. To start earning with EcoPool, download the EcoPool app and discover the benefits of Cloud Rewards and Green Crypto for yourself.

On Thursday and Friday, Base mainnet experienced two block production outages, the first incident lasted 116 minutes and the second lasted 20 minutes.
There was a complete halt of new layer-2 blocks, and the sequencer and validator nodes could not progress past the invalid block until sequencing was restored.
The team fixed the outages by applying a patch to the sequencers to ensure the journal state was properly updated during execution.
However, mitigation took longer than expected “due to infrastructure conditions unrelated to the original bug,” they said.
There was also a “race condition” after the system reset, which prevented the sequencers from catching up, causing the second outage.

Going forward, the Base engineering team plans to improve protocol “fuzz testing,” which involves bombarding the system with large volumes of random, malformed, or unexpected inputs to find bugs, and building “graceful recovery” so that validator nodes don’t need manual restarts during future incidents.
Not the first outage for Base
It is not the first sequencer-related outage for Base, which stopped producing blocks for 17 minutes in September 2024 and for around half an hour in August 2025.
Base is the second-largest layer-2 network by total value secured, which is just under $11 billion, according to L2beat.
