Ethereum mining refers to a process to validate transactions and secure the Ethereum network. However, the Ethereum network no longer supports mining, having moved to staking in 2022.

The switch to proof of stake in September 2022 made Ethereum a planet-friendly crypto, reducing energy usage by more than 99% compared to proof of work mining. Now, the network uses ether (ETH) to secure the blockchain rather than energy.

However, proof of work still sees wide usage in crypto blockchains, including Bitcoin, Ethereum Classic, Litecoin, Dogecoin, and many others. In this guide, we’ll discuss the history of mining Ethereum, as well as alternatives if you want to put your mining hardware to work.

Can You Still Mine Ethereum?

You can no longer mine Ethereum (ETH) as it transitioned to a Proof of Stake (PoS) model in 2022, which eliminates the need for mining.

Instead, Ethereum now relies on validators staking ETH to secure the network. However, many other cryptocurrencies still use the Proof of Work (PoW) consensus, allowing you to mine them for profit.

Coins like Bitcoin, Ravencoin, and Dogecoin are popular alternatives for mining. Mining offers benefits such as passive income and contributing to network security.

What Is Ethereum Mining?


Ethereum mining refers to a process of solving a puzzle to “mine” a new Ethereum block where the blockchain can hold transactions.

Miners, which are computers running specialized software, generate cryptographic hashes (a one-way encrypted string of numbers and letters) until a miner finds a hash that matches the block data and has the required difficulty level. When that miner finds a block, the miner earns a mining reward paid in ETH.

Prior to the switch to PoS in 2022, mining was the method by which the Ethereum network validated transactions and increased the supply of ether, the cryptocurrency used to pay for transactions on the Ethereum blockchain network.

Mining uses key inputs to generate a hash. Hashing refers to one-way encryption. Using a given algorithm (Keccak-256 for Ethereum transactions and Ethash for Ethereum mining), the same input will always generate the same hash output.

Hashing Example

Hashing offers a more convenient and more secure way to handle data.

For example, the entire text of Poe’s poem, The Raven, which is 1,067 words long, generates the following short hash using the Keccak-256 algorithm, which is utilized throughout the Ethereum network.

When it used PoW, Ethereum used hashes in mining, with hashing still used in many network functions following the move to PoS.

The previous block becomes a hash, the current block header becomes a hash, and block transactions are also hashed. Lastly, mining uses a nonce, a number used only once as a variable.

Miners compete to find a hash value that includes all the required data as well as the nonce, which also satisfies a difficulty level. The difficulty level changes periodically as the total network hash power ebbs and flows.

However, this is a simplified description of Ethereum mining. Ethereum blocks consider more inputs compared to Bitcoin and some other PoW networks.

Ethereum’s Move to Proof-of-Stake in 2022


Mining requires considerable energy consumption because mining nodes across the planet generate rapid-fire hashes competing to find the next block. This is the “work” in proof of work. The successful hash is the proof needed to mine a new block.

2021’s Ethereum Improvement Proposal (EIP) 3675 proposed a change from PoW to PoS. In the short term, the Ethereum chain would run PoS next to PoW, maintaining two separate chains before merging the two chains on September 15, 2022.

As a result of Ethereum’s move to PoS, mining is no longer possible on the Ethereum network. However, the way in which mining worked for Ethereum in the past still exists for Ethereum Classic. It also closely parallels the mechanics used for other proof-of-work blockchains, like Bitcoin, Litecoin, Dogecoin, and Kaspa.

How Ethereum Mining Used to Work Pre-2022


Earlier, we briefly discussed how mining centers on generating hashes to mine a new block. New blocks link a parent block using a hash as well, creating a chain. If any data in a block were to change, it would break the chain going forward by creating new hash values. The energy investment in mining (or re-mining) blocks is what makes PoW secure.

However, to mine Ethereum, mining rig operators needed specialized equipment and often banded together in mining pools to increase the frequency of mining rewards for each miner.

Choosing Mining Hardware

In the early days of crypto mining, aspiring miners could use their CPU to generate hashes. However, as network hash rates increased, the network also increased the difficulty. This caused miners to seek out more powerful hardware, including high-end graphics processors (GPUs).

Eventually, the competition to generate hashes faster led to specialized hardware, including field-programmable gate arrays (FPGAs) and application-specific integrated circuits (ASICs). These specialized devices were built for hashing rather than serving double duty, as was the case with CPUs and GPUs.

However, Ethereum’s choice of Ethash for its mining algorithm made the mining process ASIC-resistant, particularly when compared to Bitcoin, which uses SHA-2 as its mining algorithm. This brought closer parity between mining with high-end graphics cards and specialized ASICs compared to Bitcoin.

One can learn more about the intricate differences between these two popular blockchains by going through our Bitcoin vs Ethereum review.

This remains true for Ethereum Classic, which still uses PoW and can still be mined efficiently with either GPU or ASIC-equipped machines.

Selecting Mining Software

Ethereum mining software served as a connection between the network or mining pools, covered next, and the mining rigs themselves. Which software best fit the task often centered on the mining rig’s hardware and operating system.

For instance, the following table details some of the top GPU options for mining Ethereum Classic.

Software Supported OS Supported GPU
Ethminer Linux, Windows AMD, Nvidia
lolMiner Linux, Windows AMD
T-Rex Linux, Windows Nvidia
Phoenix Miner Windows Nvidia

Joining a Mining Pool

While it was theoretically possible to mine a block individually, the frequency with which a miner could successfully mine a block made solo mining impractical as the network hash rate increased. The solution was found in mining pools.

A mining pool aggregates the hash rate of individual miners so that the entire pool works toward finding a new block. When the pool successfully mined a block, the mining reward was split proportionally, usually according to the contributed hash rate of each miner.

The pool itself took a small fee, although the fee represented a tradeoff in which miners could earn mining rewards sooner, allowing them to pay for ongoing operating costs. Mining pools remain popular for leading proof-of-work blockchains.

How Ethereum Works Now with Proof-of-Stake


Ethereum’s proof-of-stake consensus mechanism allows the network to validate transactions with a fraction of the energy usage. Instead of mining (PoS), the network uses staking in which validator nodes commit ETH as collateral to help secure the network.

  • Validators must stake 32 ETH as collateral.
  • The network randomly selects validators to assemble the next block.
  • The Ethereum network randomly selects validators to assemble blocks and validate transactions.
  • Validators that successfully add a new block to the chain earn a staking reward.
  • Validators that do not follow protocol are subject to slashing, putting the staked ETH at risk.

32 ETH represents nearly $100,000 at press time, putting the idea of running a validator out of reach for most ETH holders. However, Ethereum staking platforms offer a way to get started with smaller amounts of ETH. In exchange, the staking provider usually takes a percentage of staking rewards, passing the balance to individual stakers.

Most Profitable Alternatives to Ethereum Mining


If you’re already invested in the Ethereum mining ecosystem, you can put your Ethash ASICs to use with several other coins.

However, once you get further down the list beyond Ethereum Classic, the smaller market cap of other coins may indicate liquidity challenges. In short, it might be difficult to sell the Ethash coins you mine.

Ethash ASIC-Mineable Cryptocurrencies

  • Ethereum Classic (ETC)
  • MOAC (MOAC)
  • Halo Platform (HALO)
  • TCC (TCCW)
  • EtherZero (ETZ)
  • Etho Protocol (ETHO)
  • Bitcoin (B2G)

Alternatively, you can use your GPU to mine popular cryptocurrencies. GPU mining offers more flexibility to change mining algorithms.

GPU-Mineable Cryptocurrencies

  • Monero
  • Dogecoin
  • Ravencoin

Mining Ethereum Classic

mining ethereum classic

The Ethereum chain launched in mid-2015, but by mid-2016, it had split into two chains: Ethereum and Ethereum Classic. This was a hard fork. Going forward, each chain would have its own history of transactions.

Many former Ethereum miners switched to mining Ethereum Classic when the Ethereum chain switched to PoS later in 2022. Others continue to mine ETC using Ethereum cloud mining.

Ethereum Classic is seen by some as the true chain, although both chains share a common beginning. In 2016, following a now-infamous hack of The DAO, the Ethereum blockchain split. Notably, Ethereum has a much higher market capitalization compared to Ethereum Classic.

The DAO Hack

The DAO was an early decentralized organization formed to fund upcoming projects on the Ethereum blockchain. Using a recursive calling vulnerability, an attacker drained much of The DAO’s treasury.

To undo the damage, the community voted on a proposal to invalidate transactions related to the hack. When the proposal passed, Ethereum and Ethereum Classic became two distinct chains. The Classic chain still holds transactions related to The DAO hack as valid.

Mining Other Altcoins on Proof of Work

We covered a list of Ethash-compatible coins earlier. If you own an Ethash ASIC, you’re limited to mining Ethash coins with that equipment. However, GPU mining opens up a world of possibilities.

Scrypt Algorithm Coins

  • Dogecoin (DOGE)
  • Litecoin (LTC)
  • Quantis (QUAN)

Other GPU-Mineable Cryptocurrencies

  • Vertcoin (VTC)
  • Bitcoin (BTC)
  • Haven Protocol (XHV)
  • Bitcoin Gold (BTG)
  • ZCash (ZEC)

Best Coins to Mine in 2025 – Ethereum Alternatives


With Ethereum no longer mineable, several other top cryptocurrencies offer profitable alternatives for miners:

  • Bitcoin (BTC) remains a top choice for large-scale miners using ASICs, thanks to its high value, though it’s resource-intensive.
  • For a more beginner-friendly option, Monero (XMR) stands out as it can be mined using regular CPUs, making it accessible without the need for specialized mining hardware.
  • Dogecoin (DOGE) offers fast block times and high rewards and can be mined using energy-efficient GPUs.

An even better alternative to Ethereum mining is staking, which also allows you to earn passive income from crypto.

Unlike mining, which requires expensive equipment and high energy consumption, staking allows you to earn rewards by locking up your tokens to help validate transactions on PoS chains. This makes staking more accessible and eco-friendly compared to mining, while offering consistent returns.

Conclusion


While Ethereum mining is no longer possible, several alternatives still exist, with Ethereum Classic being a common choice for those already invested in Ethereum-specific mining equipment.

GPU mining offers a wider range of options, including Bitcoin, although dependent on a rising price, Litecoin, Dogecoin, and several others. For those committed to the Ethereum space, staking offers a viable alternative, with staking reward yields typically in the 3% to 4% range.
