Bitmain released firmware for ETC mining on ASIC-miner E9. On September 2, cryptocurrency mining equipment manufacturer Bitmain added new firmware for the Antminer E9, released in July. This version will allow mining Ethereum Classic (ETC). The firmware comes ahead of Ethereum’s transition from Proof-of-Work (PoW) consensus algorithm to Proof-of-Stake (PoS), which will change the way coins are earned on the network from mining to stacking. The firmware only supports Antpool, Poolin and F2pool for now, versions for other mining pools are under development and will appear on the network soon.
