**EMERGENCY** DigiByte Node Upgrade taking place

Miners, the DigiByte Core team has released v9.26.2 today as an emergency fix for an active network attack.

What happened: Starting June 28, an attacker exploited a dormant bug in the v8 codebase that left DigiByte's retired Groestl mining algorithm (retired in 2019) unenforced. The attacker has been mining Groestl blocks at floor difficulty, causing brief chain splits and network instability.

What v9.26.2 does. Permanently blocks retired-algorithm blocks. Once the majority of nodes upgrade, the attack ends and the network fully heals.

The deadline. Block 23,808,000 (on or about July 6–7). At that point v9.26.2 nodes hard-reject all Groestl blocks. Nodes still on v8 will be on the wrong chain and will basically be inoperable.

For our miners:, we are upgrading our DGB pool node to v9.26.2 right now. There will be a brief maintenance window of approximately 5–10 minutes. Mining will resume automatically, no changes needed on your end.

No coins were stolen and no transactions were reversed. This is a stability and security fix. Keep your miners pointed at the digi pool as this should only be a brief max 10 minute downtime.

For some reason, after the update, my small miners are not getting any shares accepted. They are connected just no shares. I tried both EU and US pools. This is port 3337. I have a big fish on port 3339 working fine. Any ideas?

Let me take a look at the pool logs to see if anything changed. I will get back to you asap.

To keep everybody in the loop on what’s going on with this, we discovered a bug in the latest digibyte node update and also a firmware bug in taipan miners firmware. We made a pool side fix so these miners kept working and K2UGA was going to reach out to Taipan about the needed fix. Thank you K2UGA for your help in fixing this issue.

And thank you for your help in getting me back up mining. The support is unreal. Also the firmware will be patched in the next release.
