The Stellar (XLM) Development Foundation (SDF) has released a comprehensive post-mortem report detailing a significant network incident that occurred on October 9, 2025. The incident involved the newly implemented Soroban Live State Prioritization feature, a component of the Whisk Protocol 23 (P23), designed to enhance data handling and storage within the Stellar network.
### Incident Overview
The issue, which went undetected for 35 days, began affecting the network as early as September 4, 2025. It was discovered that a bug within the Soroban feature was corrupting certain data entries. Upon identification, the SDF moved swiftly to collaborate with affected parties and network validators to manage and ultimately resolve the problem by October 23, 2025.
### Extent of Data Corruption
In total, 478 data entries were initially corrupted due to the bug. According to the SDF, most of these entries were successfully repaired to their intended values. However, 84 data entries remained corrupted, necessitating further mitigation strategies by involved protocols and issuers.
### Response and Resolution
Once the issue was identified, the SDF prioritized containment efforts, achieving significant progress by October 10, 2025. The foundation’s technical team worked diligently to address the root cause, implementing measures to prevent similar bugs in the future.
The incident has provided valuable insights into the network’s vulnerabilities, prompting the SDF to enhance its monitoring and testing protocols to better safeguard the Stellar ecosystem.
### Lessons Learned
This incident underscores the importance of rigorous testing and continuous monitoring in blockchain technology. The SDF’s proactive approach to addressing the issue, combined with transparent communication with stakeholders, has been critical in maintaining trust and integrity within the Stellar community.
