Ethereum Classic plans ‘Thanos’ hard fork to restore mining with older GPUs
Ethereum Classic (ETC) is planning to execute the Thanos hard fork, an upgrade that would ensure several more years of mining functionality for graphics cards with 4 gigabytes of RAM. This poses a problem for many graphics cards and some ASICs used for Ethash mining, as these devices will no longer be able to mine Ethereum Classic.
The Thanos hard fork aims to halve the size of the DAG, allowing 4 GB devices to keep mining for another three years. The purpose of the hard fork is largely to attract more hash rate originating from Ethereum (ETH), which is also expected to completely throw 4 GB miners off before the end of 2020.
