Ethereum Mining Hardware in 2025: Navigating the Post-Merge Landscape

Ethereum’s September 2022 Merge replaced Proof of Work (PoW) with Proof of Stake (PoS), ending traditional mining entirely. As a result, Ethereum mining hardware became obsolete. Validators now secure the network by staking ETH, which cuts energy use and changes how rewards are earned.

Why Ethereum mining is no longer an option

Ethereum’s new PoS system replaced miners with validators, who secure the network by staking at least 32 ETH. The more they stake, the higher their chances of earning ETH rewards. This model cuts energy use by about 99%, according to the Ethereum Foundation. While Ethereum mining hardware can potentially be repurposed for mining other PoW cryptocurrencies or for other GPU-intensive tasks (like machine learning), it is no longer relevant for the Ethereum network itself.

Earning ETH without mining

The end of mining doesn’t mean you can’t earn ETH anymore. There are several alternatives you can explore to earn rewards — all without running any Ethereum mining hardware.

1. Become a validator

If you meet the 32 ETH minimum requirement and have some technical know-how, you can set up your own validator node. Validators confirm transactions and add new blocks to earn ETH for their contributions. The setup isn’t cheap, but it does offer stable returns over time.

2. Staking ETH in smaller amounts

If running your own validator isn’t feasible, staking is still accessible through two popular methods:

• Liquid staking: Platforms like Lido allow you to stake ETH and still keep your funds liquid. You receive liquid staking tokens in return, which you can trade or use in DeFi apps.
• Pooled staking: You can also join a staking pool where smaller amounts of ETH from different users are combined to run a validator. The pool then distributes rewards based on each person’s contribution.

Comparing staking and mining

• PoW mining consumed large amounts of power. Staking requires only a stable internet connection and minimal computing resources.
• Mining needed GPUs or ASICs. Staking only needs basic hardware, or none at all if you use a staking service.
• Mining rewards fluctuated with hash rate and competition. Staking offers more predictable returns based on your contribution.
• Mining required expensive setups. Staking pools and liquid staking lower that barrier significantly.

3. Provide liquidity and earn fees

You can also earn ETH by providing liquidity to ETH trading pairs on decentralized exchanges like Uniswap or SushiSwap.

4. Try yield farming

Yield farming lets you earn ETH by lending it to DeFi protocols in exchange for interest or token rewards. Returns can be high, but so are the risks — so be sure to research each protocol before depositing your ETH.
