Ethereum has undergone a transformative shift in its underlying consensus mechanism — moving from Proof of Work (PoW) to Proof of Stake (PoS). This evolution marks the end of traditional GPU-based mining as we knew it and ushers in a more energy-efficient, scalable, and secure blockchain network.
If you're looking to participate in Ethereum’s ecosystem and earn rewards, understanding both legacy mining methods and modern staking practices is essential. This guide explores everything you need to know about how to mine Ethereum — including why staking is now the dominant method, how mining pools work, and what your options are in 2025 and beyond.
Understanding Ethereum's Shift from Proof of Work to Proof of Stake
Ethereum officially completed "The Merge" in 2022, transitioning fully from Proof of Work to Proof of Stake. This means that Ethereum mining with GPUs is no longer possible. The network no longer relies on miners solving complex cryptographic puzzles; instead, validators are chosen to propose and attest blocks based on the amount of ETH they stake.

While older guides may still reference profitable GPU mining setups, those are now obsolete for Ethereum. However, this transition opens up new opportunities through staking, which is now the primary way individuals can contribute to the network and earn passive income.
Why Did Ethereum Move to Proof of Stake?
- Energy Efficiency: PoS consumes over 99% less energy than PoW.
- Security: Economic penalties ("slashing") deter malicious behavior.
- Decentralization: Lowers barriers to entry compared to expensive mining rigs.
- Scalability: Paves the way for future upgrades like sharding.
What Is Ethereum Staking?
Ethereum staking involves locking up ETH in a smart contract to become a validator on the network. Validators are responsible for proposing new blocks, verifying transactions, and maintaining consensus. In return, they earn staking rewards paid in ETH.
Unlike mining, staking does not require powerful hardware or high electricity consumption. Instead, it relies on economic commitment — the more ETH you stake, the higher your chances of being selected to validate a block (though randomness ensures fairness).
How Staking Works: The Basics
- Validators Stake 32 ETH Minimum: To run your own validator node, you must deposit exactly 32 ETH into the Ethereum 2.0 deposit contract.
- Random Selection: The protocol randomly selects validators to propose and attest blocks.
- Rewards and Penalties: Validators earn rewards for honest participation but face penalties (including partial loss of staked ETH) for downtime or malicious actions.
- Epoch-Based Cycles: Every 6.5 minutes (an "epoch"), new validators are selected, and rewards are distributed.
As of recent data, over 7.8 million ETH has been staked across the network — demonstrating strong community participation in securing Ethereum’s future.
How to Start Staking Ethereum
There are several ways to stake ETH depending on your technical expertise, capital, and risk tolerance.
Option 1: Run Your Own Validator Node
Running your own node gives you full control and typically offers the highest returns (around 6% annual yield). However, it requires:
- 32 ETH (approximately $100,000+ depending on price)
A reliable computer or VPS (Virtual Private Server) with:
- 6+ CPU cores
- 8–16 GB RAM
- 500 GB+ SSD storage
- Constant internet connection (24/7 uptime)
- Basic technical knowledge to install clients like Lighthouse, Prysm, or Teku
You’ll also need to generate two keys:
- Signing key: Used to validate blocks.
- Withdrawal key: Allows access to your staked ETH after withdrawal functionality is enabled (now live post-Merge).

Option 2: Use a Staking Pool (Liquid Staking)
Not everyone owns 32 ETH — and that’s okay. Staking pools allow users to combine their ETH and share rewards proportionally. These services often issue liquid staking tokens (like rETH or stETH), which represent your staked balance and can be traded or used in DeFi protocols.
Popular Ethereum staking pools include:
- Lido
- Rocket Pool
- Coinbase Staking
- Ankr
- StakeWise
Benefits of Staking Pools:
- No minimum ETH requirement (can start with as little as 0.01 ETH)
- No technical setup needed
- Access to liquid staking derivatives
- Lower risk of penalties due to professional node management
Yields typically range between 5%–6% annually, slightly lower than solo staking due to service fees.
Can You Still Mine Ethereum?
No. As of mid-2022, Ethereum no longer supports Proof of Work mining. The network’s difficulty bomb made mining impossible, effectively ending GPU-based mining operations.
Attempts to continue mining led to the creation of forks like Ethereum Classic (ETC), but these are separate blockchains with different ecosystems and lower market value.
However, if you already own mining hardware (e.g., RTX 3090, Radeon VII), you can repurpose it to mine other PoW cryptocurrencies such as:
- Ravencoin (RVN)
- Ergo (ERG)
- Flux (FLUX)
- Horizen (ZEN)
These alternatives offer ongoing mining profitability depending on electricity costs and market conditions.
Frequently Asked Questions
Q: Is Ethereum staking profitable?
A: Yes. With average annual yields between 5%–6%, staking offers consistent passive income. Returns depend on total network validators and participation rates.
Q: How much ETH do I need to start staking?
A: You need 32 ETH to run your own validator node. For smaller amounts, use liquid staking services with no minimums.
Q: Can I withdraw my staked ETH anytime?
A: Yes. Post-Merge upgrades have enabled withdrawals. You can unstake via official channels or liquid staking platforms instantly.
Q: Are there risks involved in staking?
A: Yes. Risks include slashing for offline nodes or double-signing, smart contract vulnerabilities (in pools), and price volatility of ETH.
Q: What are liquid staking tokens?
A: Tokens like stETH or rETH represent your staked ETH and accrue rewards over time. They’re tradable and usable in DeFi apps while your original stake remains locked.
Q: How is staking taxed?
A: In most jurisdictions, staking rewards are considered taxable income at the time they’re received. Consult a tax professional for guidance.
Mining Alternatives After Ethereum’s Transition
With Ethereum no longer mineable, many former miners have turned to alternative strategies:
Cloud Mining Services
While not recommended due to high fraud risk, some platforms offer hash rate rentals for coins like Bitcoin or Litecoin. Always research thoroughly before investing.
Joining Mining Pools for Other Coins
Pools like F2Pool, Hiveon, and Ethermine (now rebranded) support mining for various PoW assets. These allow shared hashing power and more consistent payouts.
Repurposing Mining Rigs
Old GPU rigs can be used for:
- Rendering farms
- AI training tasks
- Privacy-preserving computations
- Gaming PCs or resale
Final Thoughts: The Future Is Staking
The era of Ethereum mining is over — but the opportunity to earn from the network has never been more accessible. Whether you're a seasoned validator or a beginner using a staking pool, participating in Ethereum’s security and growth is easier than ever.
Staking aligns incentives across the ecosystem: users secure the network, earn yield, and support decentralization — all without noise, heat, or massive electricity bills.
