Aptos Blockchain Network Outage: Post-Mortem Reveals Key Details
A recent post-mortem of the 5-hour-long network outage that plagued the Aptos platform has revealed multiple details about the disruption. The layer-1 Aptos blockchain network experienced a significant outage on its one-year anniversary, disrupting operations for a period of five hours and fifteen minutes. Importantly, the network issues were not due to transaction load or network capacity concerns.
Code Change Identified as Culprit
The Aptos network team released a post-mortem report stating that the root cause of the outage was a performance-focused code change implemented in August. This change had adverse effects following the launch of the “FeeStatement event” on October 16. Validators were unable to agree upon the amount of gas used in a transaction due to non-determinism introduced by the code change.
Resolution and Precautions Taken
Aptos swiftly resolved the issue without losing any committed transactions or experiencing a network fork. They identified and reverted the problematic code change, allowing validators to upgrade to the fixed software and regain consensus. The incident serves as a lesson for the blockchain community, emphasizing the importance of rigorous testing when implementing code changes. Aptos will strengthen its testing infrastructure and processes to prevent similar issues in the future.
APT Price Outlook
Aptos’ native token, APT, has maintained stability despite the network disruption. At present, APT is trading at $4.93 with a modest 1.2% increase for the day. However, it has been affected by the recent bear market, experiencing a 5.7% loss over the past two weeks. Regular token unlocks have also contributed to its decline of 75% from its all-time high in January 2023.
Hot Take: Lessons Learned from Aptos Network Outage
The Aptos network outage serves as a reminder of the importance of rigorous testing and caution when implementing code changes in the blockchain community. This incident highlights the need for thorough testing, especially for edge cases, to avoid disruptions and maintain network stability. Aptos has taken steps to address the issue, reverting the problematic code change and strengthening its testing infrastructure. Moving forward, it is crucial for all blockchain projects to prioritize testing and implement robust measures to prevent similar incidents from affecting their networks.
