Mining Ethereum: Is It Still Possible? Updated 2026 Guide
If you are searching for how to mine Ethereum, it is important to start with one key clarification: today, it is no longer possible to mine ETH on the Ethereum Mainnet. Mining, which for years was the mechanism used to produce new blocks and distribute rewards to miners, was abandoned with The Merge, completed on September 15, 2022. From that moment, Ethereum replaced Proof of Work with Proof of Stake, entrusting network validation to validators who participate by staking ETH.
This does not mean that cryptocurrency mining has disappeared. Rather, it means that Ethereum and ETH can no longer be mined as they were before 2022. To understand what has changed and what opportunities remain today, it is therefore necessary to distinguish between Ethereum’s historical mining model, today’s staking system, and other blockchains that continue to use Proof of Work.

Can You Still Mine Ethereum?
The answer is no, not on the Ethereum Mainnet.
Ethereum’s official documentation states that Proof of Work is no longer the network’s consensus mechanism and, as a result, mining has been disabled. Blocks are now produced and validated through Proof of Stake, with validators staking ETH to participate in consensus.
The change took place with The Merge, the upgrade carried out on September 15, 2022, which merged the Ethereum Mainnet with the Beacon Chain, the Proof-of-Stake-based blockchain. With this transition, Proof of Work was permanently replaced, and mining is no longer a valid method for producing blocks on the Ethereum network.
IMPORTANT: this point is essential because many guides still available online explain how to mine Ethereum using GPUs, mining pools, or other hardware, referring to a system that is no longer current. Ethereum.org itself keeps its mining page online exclusively for historical purposes and specifies that the information refers to the now-deprecated Proof-of-Work architecture.
What Has Changed in Practice?
Before The Merge:
miners used computing power to participate in Proof of Work;
hardware performed the calculations required to produce blocks;
rewards were associated with mining;
energy consumption, hardware, and operating costs were central aspects of the activity.
Today:
Ethereum uses Proof of Stake;
miners have been replaced by validators;
block production and validation no longer require mining;
anyone who wants to participate directly in consensus can do so by staking ETH according to the network’s rules.
The network’s energy consumption has also changed dramatically: according to Ethereum.org, The Merge reduced Ethereum’s energy consumption by approximately 99.95%.
So, if you own a GPU or ASIC today and are looking for a way to use it to “mine Ethereum,” you cannot connect it to the Mainnet and receive ETH through mining. To understand what alternatives are still available, we first need to look at how Ethereum mining worked before The Merge.
How Did Ethereum Mining Work Before The Merge?
Before the transition to Proof of Stake, Ethereum used Proof of Work (PoW), and mining was the mechanism through which miners contributed to network security and block production. The principle was similar to the one used by Bitcoin, but Ethereum used the Ethash algorithm, designed to require a significant amount of memory and make mining particularly suitable for GPUs.
Proof of Work and Ethash
Miners had to continuously perform calculations to find a valid solution according to the network’s rules. The available computing power determined the hashrate and, consequently, the ability to compete in block production.
Ethash had different characteristics from the SHA-256 algorithm used by Bitcoin. Its memory-hard structure favored the use of graphics cards for a long time, making it possible to mine Ethereum through configurations consisting of multiple GPUs.
GPUs, Hardware, and Energy Consumption
To mine ETH before 2022, the main requirements were:
sufficiently powerful GPUs with adequate memory;
a power supply capable of supporting the mining setup’s energy consumption;
a stable Internet connection;
a cooling and ventilation system;
software and firmware to manage the machines;
an Ethereum wallet to receive rewards;
a mining pool, if you chose to participate in the network through collective mining.
A mining facility had to manage energy consumption, heat, maintenance, and operational continuity, factors that became increasingly important as the size of the operation grew.
Mining Pools and Rewards
To increase the frequency of rewards, many miners joined a mining pool. Under this model, the computing power of multiple participants was combined, and rewards were distributed based on each participant’s contribution.
However, this system is now part of Ethereum’s history: with The Merge, the network permanently abandoned Proof of Work and mining. Today, ETH is no longer produced through GPUs, ASICs, or mining pools on the Mainnet.
Ethereum Mining vs. Staking: What Is the Difference?
The transition from Proof of Work to Proof of Stake changed the mechanism through which the Ethereum network reaches consensus. Before The Merge, miners used computing power and hardware to participate in block production. Today, this role is performed by validators who participate in Proof of Stake by staking ETH.
Aspect | Ethereum Mining (PoW) | Ethereum Staking (PoS) |
Mechanism | Proof of Work | Proof of Stake |
Participants | Miner | Validator |
Resource used | Computing power | Staked ETH |
Hardware | GPUs and other compatible devices | Hardware to run a validator node |
Energy consumption | High | Much lower |
Function | Calculate the solution required by PoW and propose blocks | Propose and attest blocks according to PoS rules |
Current status | No longer used on Ethereum | Ethereum’s current mechanism |
Mining: Computing Power at the Core of the System
Under the Proof-of-Work model, network security depended on the computational work performed by miners. Hardware continuously performed calculations to find a valid solution, and the miner who successfully produced a valid block could receive the reward established by the protocol. This model therefore made hashrate, hardware efficiency, and electricity costs essential factors. More generally, mining required infrastructure capable of keeping machines operational, managing the heat they generated, and sustaining their energy consumption. With The Merge, this mechanism was permanently disabled on the Mainnet: Ethereum no longer uses miners’ computing power to produce blocks.
Staking: ETH and Validators Replace Mining
Under Proof of Stake, miners are replaced by validators. Instead of providing computing power to compete in Proof of Work, participants stake ETH and may be selected to propose blocks and participate in network validation. For this reason, talking about “Ethereum mining” and “Ethereum staking” today as though they were two alternative ways of doing the same thing can be misleading. Both involve participating in the operation of the network, but the mechanisms, requirements, and risks are different.
The Most Obvious Change? Energy Consumption
One of the most significant effects of The Merge concerns the energy required to maintain network consensus. Ethereum.org reports an approximately 99.95% reduction in energy consumption compared with Proof of Work.
Why Is Cryptocurrency Mining Still Worth Considering?
The fact that Ethereum can no longer be mined does not mean that cryptocurrency mining has disappeared. There are still blockchains that use Proof of Work and, consequently, mining activities that can generate digital assets through dedicated hardware.
The real question, however, is no longer simply “Which cryptocurrency can I mine?” Rather, it is “Under what conditions can mining be an economically sustainable activity?”
Today, the outcome depends on a combination of factors: energy costs, machine efficiency, network difficulty, the price of the asset produced, operational continuity, and management costs. For this reason, simply purchasing an ASIC or GPU and connecting it to the network is not enough to build a competitive mining operation. The infrastructure surrounding the hardware can make the difference.
Competitive energy costs, adequate cooling, continuous monitoring, maintenance, and energy optimization directly affect the ability to keep machines running and manage costs over time. This is precisely what marks the transition from amateur to professional mining: instead of treating the machine as a standalone product, it becomes part of a system designed to operate efficiently and continuously.

Why Choose a Professional Mining Partner?
Approaching mining through professional infrastructure primarily means reducing the operational complexity that comes with managing machines directly. In the Bcrypto model, the main elements are:
Owned hardware: ASIC machines are purchased by the client and remain their asset;
Dedicated infrastructure: ASICs are hosted in professional mining farms;
Technical management: maintenance and 24/7 monitoring are handled by the Bcrypto team;
Optimization: operating parameters and energy consumption are monitored to maintain machine efficiency;
Control: clients can monitor production through a dashboard and identify their own machines;
Transparency: revenue is credited directly to the company wallet.
All of this makes it possible to approach mining with infrastructure designed to effectively manage the variables that determine its efficiency. And this is precisely where the difference lies between buying a machine and building a real mining operation.
Mining Has Changed, It Hasn’t Ended
Mining Ethereum is no longer possible: since 2022, the Mainnet has used Proof of Stake, and ETH mining belongs to the network’s history. Crypto mining, however, continues to exist on blockchains that use Proof of Work. Today, approaching it competitively requires much more than simply choosing the right hardware: energy, infrastructure, cooling, monitoring, maintenance, and optimization are essential components of the activity.
For those who want to turn mining into a structured project, relying on a specialized partner can therefore be an alternative to independently managing all these aspects.
