The era of Ethereum mining is coming to an end, and major mining infrastructure is preparing for the shift. Bitfly, the company behind the widely used Ethermine mining pool, has announced that it will officially shut down its Ethereum (ETH) mining operations on September 15, 2025. This marks a pivotal moment in the blockchain’s evolution as Ethereum fully transitions from a proof-of-work (PoW) to a proof-of-stake (PoS) consensus mechanism.
After this date, GPU and ASIC miners will no longer be able to mine ETH on the Ethereum network. As a result, the Ethermine pool will switch to withdrawal-only mode, allowing users to access their remaining balances but no longer accept new mining submissions.
The End of an Era: Ethereum Mining Comes to a Close
For years, Ethermine has been one of the largest and most trusted Ethereum mining pools, serving hundreds of thousands of miners worldwide. However, with Ethereum’s long-anticipated merge complete and the network now secured through staking rather than mining, the need for large-scale PoW infrastructure has vanished.
“The mining phase of Ethereum will end on September 15, 2025,” Bitfly confirmed in its official announcement. “After this date, ETH mining via GPU or ASIC hardware will no longer be possible.”
A countdown timer will be displayed on the miner dashboard, giving users real-time visibility into the final moments of active mining. Once the timer reaches zero, all Ethermine ETH servers will be permanently shut down, and miners will lose the ability to connect their rigs to the pool.
This decision reflects the broader industry trend: as blockchain networks evolve toward more energy-efficient models, traditional mining operations must either adapt or cease.

No Dedicated Support for PoW Forks
One of the most significant aspects of Bitfly’s announcement is its stance on potential Ethereum PoW forks. Despite speculation around continued mining through hard-forked versions of Ethereum that maintain PoW, Bitfly has decided not to support any such fork with dedicated mining pools.
This strategic move signals a clear alignment with Ethereum’s official roadmap and avoids fragmenting resources across uncertain spin-offs. While some mining communities may attempt to sustain PoW-based ETH variants, Bitfly is choosing to focus on established, long-term viable networks instead.
This decision also reduces operational complexity and security risks associated with supporting unstable or low-adoption forked chains.
Fee-Free Mining Promotion on Alternative Networks
In a goodwill gesture to its mining community, Bitfly will offer zero-fee mining across several alternative proof-of-work blockchains throughout September 2025. This promotion applies to:
- Ethereum Classic (ETC)
- Ravencoin (RVN)
- Ergo (ERG)
- Beam (BEAM)
Miners affected by the shutdown can redirect their hardware to these networks without incurring pool fees during the transition month. This provides a valuable opportunity for miners to recoup costs and explore sustainable alternatives in the post-Ethereum mining landscape.
Each of these networks maintains active developer communities and real-world use cases:
- Ethereum Classic continues to champion immutability and decentralized governance.
- Ravencoin specializes in asset issuance and tokenized ownership.
- Ergo emphasizes formal verification and advanced smart contract security.
- Beam focuses on privacy-preserving transactions using Mimblewimble technology.
By supporting these ecosystems, Bitfly helps preserve the decentralized mining ethos even as major chains shift toward staking.
What Miners Should Do Now
If you're currently mining Ethereum via Ethermine or another Bitfly-operated pool, here are key steps to take before September 15:
- Monitor the Dashboard Countdown: Keep track of the official timer on your miner interface.
- Withdraw Remaining Balances Promptly: Ensure all earned ETH is withdrawn before the pool goes offline.
- Reallocate Hardware Strategically: Consider switching to one of the fee-free alternative pools during September.
- Evaluate Long-Term Viability: Research future profitability based on electricity costs, network difficulty, and coin price trends.
It’s also wise to update firmware, check rig health, and ensure smooth transitions to minimize downtime.
Frequently Asked Questions (FAQ)
Q: Why is Ethermine shutting down its ETH mining pool?
A: The shutdown follows Ethereum’s permanent transition to proof-of-stake, which eliminates the need for mining. Without PoW validation, there is no role for traditional mining pools like Ethermine on the main Ethereum network.
Q: Can I still mine Ethereum after September 15?
A: Not on the official Ethereum chain. However, some forks may continue PoW mining. Note that Bitfly will not support these forks with dedicated pools.
Q: What happens to my unpaid mining rewards?
A: You’ll retain access to your balance in withdrawal-only mode. Make sure to claim all funds before services are fully decommissioned.
Q: Is zero-fee mining available on all Bitfly pools?
A: No—only Ethereum Classic, Ravencoin, Ergo, and Beam pools will have 0% fees during September 2025.
Q: Will Ethermine return if Ethereum reverts to PoW?
A: There are no current plans for such a reversal. The Ethereum community overwhelmingly supports PoS for scalability and sustainability.
Q: Where can I stake ETH now instead of mining?
A: Staking is available directly through platforms that support validator services or liquid staking derivatives.

Looking Ahead: The Future of Decentralized Mining
While Ethereum’s move away from mining represents progress in efficiency and environmental responsibility, it also raises concerns about centralization risks in staking pools and validator concentration.
Proof-of-work may be fading from Ethereum, but it remains vital to other blockchain ecosystems that value miner decentralization and ASIC resistance. Networks like Ergo and Ravencoin are stepping into this space with innovation in consensus algorithms and economic models.
For miners, this transition isn’t just about changing pools—it’s about adapting to a shifting technological landscape. Those who embrace flexibility, energy efficiency, and emerging opportunities will continue to thrive.
As blockchain technology evolves, so too must its participants. The end of ETH mining isn’t a conclusion—it’s a transformation.
