Ethereum Classic will continue to use the Proof-of-Work (PoW) methodology while the Ethereum network works to switch to a Proof-of-Stake (PoS) model. With PoS, Ethereum will fundamentally alter how it verifies blocks, adds them to the blockchain, and creates new ether (ETH).
By doing this, the demand for specialist mining rigs like those produced by Bitmain will disappear. These rigs will continue to mine Ethereum Classic's native currency, ETC. To improve the network's overall performance, the initial $10 million investment was used to create and test applications for the Ethereum Classic mainnet.
Early in July, Bitmain began selling the Antminer E9, its most recent Ethereum mining device. The second-largest cryptocurrency network is moving away from Proof-of-Work (PoW) technology. Still, Bitmain, the world's top maker of bitcoin (BTC) miners, will begin selling a new Ethereum rig model on its website. Additionally, the manufacturer of the mining rigs declared that it will now take ETC payments for all of its Antminer models during the World Digital Mining Summit in Miami.
