The long-anticipated transition of the Ethereum network from Proof-of-Work (PoW) to Proof-of-Stake (PoS), known as "The Merge," marks a fundamental shift in the blockchain's operation and profoundly impacts the GPU mining community. This guide explains the transition, its implications, and the viable alternatives for miners.
Understanding the End of Ethereum Mining
Ethereum developers triggered the switch using a specific network parameter called Total Terminal Difficulty (TTD). The TTD is a complex value that increases with each new block mined. The Merge was scheduled to occur once the network reached a predetermined TTD value.
This event signifies the complete end of Ethereum mining. The network ceases to accept new blocks created through the Proof-of-Work mechanism. Consequently, the process of mining ETH with GPUs or ASICs is permanently discontinued.
How the Merge Transition Unfolded
The transition was a definitive shift in consensus mechanisms. Contrary to some rumors, mining difficulty did not merely increase; the PoW chain was entirely replaced. At the precise moment the TTD target was met, the ability to discover new ETH blocks and receive mining rewards ceased.
This change was engineered to be a seamless upgrade for Ethereum users and holders, but it represented an absolute endpoint for miners.
Navigating the Post-Merge Landscape as a Miner
For those operating on mining pools, the immediate aftermath involved the finalization of outstanding payments. Reputable pools processed all unpaid balances that were above the minimum payout threshold, typically without requiring any action from the miner.
The critical task for miners was to reconfigure their hardware for alternative cryptocurrencies. This process involves three key changes:
- Selecting a new coin to mine.
- Changing the pool address in the mining software.
- Switching the mining algorithm to one the new coin supports.
Top Alternatives for GPU Mining After Ethereum
With Ethereum mining concluded, a significant amount of hash power migrated to other GPU-mineable networks. While profitability fluctuates based on market conditions and network difficulty, several established coins emerged as primary alternatives.
Ethereum Classic (ETC)
Ethereum Classic, which continued the original Ethereum blockchain philosophy, uses a modified version of the Ethash algorithm called Etchash.
Key Advantages:
- Similar mining algorithm makes the transition relatively straightforward.
- Often shares the same wallet address format as Ethereum, simplifying setup.
- Supported by a large mining community and many exchanges.
To switch, miners must point their software to an ETC pool and change the algorithm to etchash.
Ravencoin (RVN)
Ravencoin is a blockchain designed specifically for the transfer of assets, utilizing the KawPow algorithm.
Key Advantages:
- ASIC-resistant algorithm, favoring GPU miners.
- Strong and dedicated community.
- Clear use case and development roadmap.
A crucial note: RVN uses a different address format from ETH. Miners must ensure they are using a valid Ravencoin wallet address when configuring their software. The algorithm must be changed to kawpow.
Ergo (ERG)
Ergo is a flexible and decentralized platform focusing on financial contracts, using the Autolykos2 algorithm.
Key Advantages:
- Designed to be ASIC-resistant.
- Focuses on decentralization and long-term sustainability.
- Offers innovative smart contract capabilities.
Like Ravencoin, Ergo requires a wallet address specific to its network. The mining algorithm is autolykos2.

Strategic Considerations for GPU Mining in the Current Climate
The post-Merge mining environment is more dynamic and competitive. Success requires a more active strategy than simply setting a rig to mine Ethereum.
- Monitor Profitability Closely: Use online calculators frequently to track which coin is most profitable for your specific hardware, as network difficulties can change rapidly.
- Factor in Operational Costs: Electricity cost is now a more significant factor in determining net profit. Calculate your energy consumption against potential earnings.
- Hardware Compatibility: Check the memory (DAG file size) requirements for different coins. While some older 4GB cards can still mine certain cryptocurrencies, their window of viability is closing.
- Diversify Your Approach: Don't hesitate to switch between coins as profitability shifts. Flexibility is key to maximizing returns.
Mining with Nvidia GPUs
Nvidia graphics cards are known for their flexibility across a wide range of mining algorithms. Even older models can remain marginally profitable if energy costs are low. High-end Nvidia cards, like the RTX 3070 Ti or 3080, can handle more demanding algorithms, potentially offering a haven of higher profitability.
Mining with AMD GPUs
AMD cards often provide a different cost-to-performance ratio. While they may support fewer algorithms outright, software developments have expanded their capabilities. Models like the RX 580 or 6800 XT can still generate returns on several prominent coins like RVN and ERG, provided operational costs are managed effectively.
Frequently Asked Questions
What exactly happened during The Merge?
The Merge was Ethereum's transition from a Proof-of-Work (PoW) consensus mechanism, where miners validate transactions, to a Proof-of-Stake (PoS) system, where validators stake ETH to secure the network. This eliminated the need for energy-intensive mining on the Ethereum blockchain.
Can I still mine Ethereum?
No, you cannot mine the native Ethereum (ETH) coin anymore. The blockchain no longer produces blocks through mining. Any mining activity labeled "Ethereum" is likely referring to a fork or a completely separate project.
What is the most profitable coin to mine now?
Profitability changes constantly based on coin price, network difficulty, and electricity costs. There is no single "best" coin. The most effective strategy is to use a profitability calculator, input your hardware and electricity rate, and mine the top-ranked coin, being prepared to switch when conditions change.
Do I need new hardware to mine other coins?
In most cases, no. Your existing GPU mining rig can be repurposed by simply reconfiguring your mining software with a new pool address, algorithm, and wallet address for your chosen alternative coin.
What happened to the EthereumPoW (ETHW) fork?
A faction of the community created a fork of the pre-Merge Ethereum blockchain to continue Proof-of-Work mining. While it launched, its long-term viability, security, and value depend entirely on community support and exchange adoption, making it a highly speculative venture compared to established alternatives.
How do I stay updated on the best mining opportunities?
The crypto mining space moves quickly. To make informed decisions, follow reputable mining pools, stay engaged with community discussions on platforms like Telegram or Reddit, and consistently use profitability tools to assess your options. 👉 Get advanced methods for tracking crypto trends
