Ethereum Classic Activates Thanos Upgrade, Increasing Access for GPU Miners

Terry Culver, CEO at ETCLabs, told CoinDesk Thanos is an “important milestone” as the network moves to improve support for existing miners and draw in new ones. Specifically, the Thanos (ECIP-1099) protocol upgrade will bring the size of the DAG (Directed Acyclic Graph) file well below 4GB, meaning 3GB and 4GB graphics processing units (GPUs) can once more mine the network.

The upgrade will allow miners with 3GB and 4GB GPU systems to resume mining ETC, “ultimately increasing network security and promoting a more distributed and healthy mining ecosystem,” said Culver. Before the upgrade, the DAG size was already very close to 4GB, forcing some older GPU mining cards off the network.
