Ethereum mining is the process of verifying transactions on the Ethereum blockchain. Miners use specialized computers to solve complex math problems that validate blocks of transactions. In return, the miners receive Ether, Ethereum’s cryptocurrency, as a reward.
In 2024, Ethereum mining remains an important part of securing the network, processing transactions, and rewarding participants. However, Ethereum is transitioning from proof-of-work (PoW) based mining to proof-of-stake (PoS) validation in an upgrade known as The Merge. This article provides an updated, comprehensive overview of Ethereum mining in 2024 – how it works, hardware and software needs, profitability, and what the future looks like.
How Ethereum Mining Works
Ethereum, like Bitcoin and most other cryptocurrencies, runs on a decentralized network supported by nodes run by miners. Miners serve several crucial roles:
- Processing Transactions – Miners collect pending transactions from the network and include them in blocks. This confirms the transactions and secures them on the blockchain.
- Securing the Network – By dedicating computing power to process transactions, miners make attacks on the network more difficult. More miners means greater security for Ethereum.
- Emission of Ether – Miners receive newly created Ether tokens as a reward for successfully adding new blocks to the chain. This is Ethereum’s version of “minting” new cryptocurrency.
In 2024, Ethereum still relies on proof-of-work mining, although this is expected to change later in the year with the completion of The Merge. Currently, here is the process miners follow:
- Download a full copy of the Ethereum blockchain from peers in the network. This allows the node to verify new blocks and transactions.
- Install mining software to connect your hardware to an Ethereum pool or solo mine blocks. Software manages your hardware’s activity.
- Choose transactions from the pending transaction pool to include in a block. Try to maximize fees earned from transactions.
- Calculate the cryptographic hash for the candidate block with a Nonce value. The output must be below the current Difficulty target set by the network.
- Check if hash output qualifies the candidate block. If not, change Nonce and repeat. This is the core “mining” process and requires massive computing power over time.
- Submit qualifying block to the network. If valid, the block will be added to the chain and the miner is rewarded in Ether.
This is still a high level summary – getting set up for Ethereum mining requires in-depth technical knowledge or joining a pool which handles most details for you.
Ethereum Mining Hardware
Ethereum mining requires computers specialized for mining, called “rigs”, to solve math problems efficiently. Most rigs consist of graphics cards (GPUs) which excel at parallel processing tasks.
In 2024, here are popular GPUs used in Ethereum mining rigs:
- Nvidia RTX 3060 Ti – A top selling card for gaming that also mines Ethereum well. Lower price and power efficiency makes it popular for small rigs. Around 60 MH/s hashrate.
- Nvidia RTX 3070 – An extremely efficient card for 1440p gaming and Ethereum mining. Can reach 60-62 MH/s hashrate with proper memory overclocking.
- AMD Radeon RX 6800/6800 XT – AMD’s top mining cards, hashrate of up to 62 MH/s. Also great for gaming and content creation which helps resale value.
- Nvidia RTX 3090 Ti – Nvidia’s flagship cardi for performance, capable of ~124 MH/s with some mods. Very power hungry at 350W however. Good for well-financed mining ops.
Miners run many GPUs together to form mining rigs. Components like motherboards, CPUs, RAM and SSDs are standard. Key considerations are:
- Number of GPU slots – More room for expansion. Mining motherboards have up to 19 PCIe slots.
- CPU – Don’t need much CPU power, so older chips work. Need support for many GPUs.
- RAM – 8GB is standard, 16GB recommended for stability in big rigs.
- Storage – A small SSD stores the operating system and mining software.
- Power Supply – 1000W+ recommended for high end rigs. Gold or Platinum rated for efficiency.
- Case – Open air rigs optimal for GPU cooling, particularly for large scale operations.

Ethereum Mining Software
In additional to hardware, dedicated software is required to manage the mining activity. Ethereum mining software handles critical functions like:
- Communicating with the Ethereum network and pool
- Controlling and monitoring GPU settings like clock speeds and voltages
- Optimizing systems settings to improve mining efficiency
- Tracking real time metrics on mining status
- Updating GPU drivers and software
Here are the most common Ethereum mining software options in 2024:
Windows Mining Software
- lolMiner – Popular stable mining software for AMD and Nvidia GPUs. Mine Ethereum along with Ethereum Classic and other coins.
- GMiner – Supports both Nvidia and AMD cards. Provides detailed stats to track performance.
- PhoenixMiner – Mines both Ethereum and Ethereum Classic. Known for reliability and speed.
Linux Mining Software
- Ethminer – Open source command-line software tailored to Ethereum mining using GPUs. Does not support ASICs.
- CGminer – General purpose Linux mining software supports GPU/FPGA/ASIC mining. Works for many coins.
- TeamRedMiner – Mines coins on proof-of-work algorithms. Optimized for AMD GPUs but works on Nvidia too.
For casual mining, Windows GUI software like Nicehash quickminer offers a simple setup. Expert and enterprise miners often use Linux rigs capable of large scale, customized deployments through command line interfaces.
Ethereum Mining Pools
While it’s possible to mine Ethereum alone, most individual miners join Ethereum mining pools. These allow miners to combine computing power to improve their chances of validating blocks and earning mining rewards. Instead of consistent small payouts, miners earn a share of the overall pool’s success based proportionate to the hashrate they contribute.
Here are popular Ethereum mining pools in 2024:
- Ethermine – The most popular pool for Ethereum miners, known for stability, high profitability and good customer support.
- F2Pool – Another large, China-based pool operating since 2013. Mines a variety of PoW coins.
- SparkPool – Leading pool based in China with mining servers around the globe. Mines ETH, GRIN and other coins.
- Nanopool – Created by Ethereum developers focusing on user experience and ease of setup. Stable with low fees.
When choosing a mining pool, key factors to consider are total network hashrate, fee structures, payout schemes, and server locations. Most miners opt for larger, well established pools for consistent earnings and support. Solo mining is an advanced approach with high profit potential but inconsistent results.
Is Ethereum Mining Profitable in 2024?
In 2024, Ethereum mining remains profitable, but rewards have fallen from their highs for several reasons:
More Competition
- Extremely profitable mining between 2020 to mid 2022 led to more miners competing, increasing network difficulty. Similarly, progress in GPUs results in faster hashrates.
The Merge to Proof-of-Stake
- Ethereum is expected to complete its shift from PoW to PoS consensus in 2024. This will phase out rewards for GPU miners over time in favor of validators staking ETH.
Price Declines From Early 2022 Peak
- While still robust, ETH prices around $1500 in early 2024 are down 50% from their peak. This cuts directly into fiat mining profits.
In light of these trends, mining ETH and other coins remains profitable with efficient modern hardware. However profit margins have contracted significantly at over 2x higher network difficulty. Miners now target $0.10 to $0.15 per kWh for viability, depending on equipment and electricity costs.
Using advanced ASICs instead of GPUs can still achieve solid returns where electricity is very cheap, such as parts of China and Central Asia. However most retail miners utilize graphics cards.
The Future of Ethereum Mining
The biggest upcoming change for Ethereum mining is The Merge – the transition from proof-of-work to proof-of-stake consensus planned to roll out in 2024. This shift away from mining has been in Ethereum’s roadmap since inception.
Here is the expected timeline for The Merge rollout:
- Q2 2024: Final public Ethereum testnets merge – This tests the PoS upgrade on a live environment as final preparation.
- Q3/Q4 2024: Ethereum mainnet executes The Merge – If all goes well, Ethereum will officially switch to PoS during this window.
Once The Merge is activated, transaction validation will shift from miners to validators staking ETH. Ethereum’s issuance model and energy usage are expected to reduce drastically.
Initially, Ethereum mining rewards will decrease by ~90% but some blocks will still require PoW for a period after The Merge. Once PoS reaches finality however, PoW mining ends on Ethereum outside of niche use cases.
Many current Ethereum miners are preparing by shifting hardware to mine alternative GPU-friendly coins. Popular options include Ravencoin (RVN), Ethereum Classic (ETC) and Ergo (ERGO) which will continue utilizing PoW. These have seen large hashrate increases in early 2024.
So while an era is ending, Ethereum mining still soldiers on until The Merge gives way to proof-of-stake. Miners have provided a vital service securing the network and look set to redeploy equipment to new pastures.
Ethereum Mining – Conclusion
Ethereum mining pioneered GPU mining to open up crypto consensus to everyday users. It enabled a vibrant, decentralized network supporting Web3 innovation.
Even in 2024, mining remains important for Ethereum until The Merge finally transitions the chain to a greener and more scalable proof-of-stake model later in the year.
While Ethereum mining as we know it fades into history, the expertise and community built will endure to drive forward open, permissionless blockchains into the future.
