Firo will perform a hard fork upgrade on October 26, 2021 at 06:00 UTC. The mining algorithm will be changed from MTP to FiroPoW with a starting DAG size slightly over 4 GB and an increase of 8 MB every 1300 blocks (~4.5 days).

Please note that you may not be able to generate any profit from mining with the same software you used before, thus you should switch to the latest version of software such as T-Rex and TeamRedMiner. You may also refer to our Firo mining tutorial for more details.
