✅ Final Incident Update TL;DR: All systems green - situation resolved, no urgent upgrade needed. We’re happy to confirm that Alephium is back to normal and that no urgent network upgrade is necessary. As we hoped, the mining pool’s adjustment to its hashrate distribution strategy was sufficient to bring the network back to a stable state. With this change, the trigger that caused the spike can no longer reproduce under current conditions. The penalty mechanism will be adjusted in a future upgrade to avoid excessive impact in edge cases. While this behavior caused a temporary performance degradation, it cannot be weaponized efficiently. During the incident: - Network difficulty increased, degrading performance - Block times peaked at ~2.5 minutes - Transactions still went through, just more slowly - Miners were the most impacted by the increased difficulty - The network remained secure and operational throughout We’re continuing to monitor the chain. The team will now take a bit of rest and finalize the investigation so we can publish a detailed postmortem in the coming week or two.

🙏 A huge thank you to all the mining pools and ecosystem participants who made themselves available, in the middle of the night or during the weekend, and stood ready to deploy quickly if needed.

And to the Alephium community: your support, vigilance, and patience helped make this resolution as painless and swift as possible. 💜

And finally, thank you to the core contributors, some of whom worked nearly 40 hours straight, came back from holidays, or woke up at 4 a.m. on a Saturday to help resolve the situation. Special shoutout to @wachmc , @hongchao , Muchen, @MaudBannwart and @babyxDDD!
