As the Ethereum network transitions from proof-of-work (PoW) to proof-of-stake (PoS) with The Merge, a pivotal shift has sent ripples across the mining ecosystem. For miners who relied on computational power to validate transactions and earn rewards, this change marks the end of an era on Ethereum’s mainnet. Yet, it also opens new pathways—most notably toward alternative PoW chains like Ethereum Classic (ETC) and the newly emerged EthereumPoW (ETHW).
This article explores the evolving landscape for miners post-Merge, comparing ETHW and ETC in terms of technology, community support, security, and market performance. We’ll examine which chain offers a more sustainable future for miners and why one may be pulling ahead in this high-stakes race.
The Post-Merge Mining Dilemma
With Ethereum abandoning mining, thousands of GPU and ASIC miners faced an urgent decision: shut down operations or migrate to another blockchain that still supports PoW consensus.
Two primary options have emerged:
- Ethereum Classic (ETC): The original continuation of Ethereum’s PoW chain after the 2016 DAO fork.
- EthereumPoW (ETHW): A hard fork created specifically to preserve Ethereum’s mining model post-Merge.
While both aim to sustain mining, their approaches, governance models, and market reception differ significantly.

EthereumPoW (ETHW): A Community-Driven Fork
Launched shortly after The Merge, ETHW was designed as a direct response to the Ethereum community’s shift away from mining. Backed by a coalition of miners and developers, ETHW emphasizes decentralization, open access, and resistance to centralized control.
Core Principles of ETHW
- No restricted pools: All mining pools are welcome; none will be blacklisted.
- No contract freezing: Unlike past interventions (e.g., the DAO rollback), ETHW vows never to reverse transactions or freeze funds.
- Inclusive wallet policy: Even wallets associated with controversial actors—such as hackers—are accepted, reinforcing its commitment to neutrality.
- Immutable ledger: Once recorded, transactions cannot be altered, ensuring long-term trustlessness.
These principles reflect a strong ideological stance: code is law, regardless of external pressures.
However, this absolutist approach raises concerns about regulatory scrutiny and security vulnerabilities—especially regarding replay attacks.
Replay Attack Risks and ChainID Controversy
A critical technical issue facing ETHW is the risk of replay attacks—where a transaction on one chain is maliciously or inadvertently repeated on another. This becomes possible if two chains share the same ChainID, a unique identifier used to differentiate networks.
As highlighted by MakerDAO, there was initial concern that ETHW might use the same ChainID as Ethereum’s new PoS chain, creating potential chaos for DeFi protocols like Maker, which issues the DAI stablecoin.
"Once the Merge takes place, a forked Ethereum PoW chain appears to be imminent, with a non-zero chance that it will use the same chainId as the PoS chain."
Thankfully, ETHW developers implemented EIP-3788, updating the ChainID to prevent cross-chain replay attacks. This move improved interoperability safety and reassured DeFi integrators.
Still, questions remain about long-term adoption and ecosystem growth beyond mining incentives.
Ethereum Classic (ETC): Stability Meets Longevity
While ETHW made headlines as a reactionary fork, Ethereum Classic has existed since 2016 and has steadily built resilience over time. As the original PoW version of Ethereum, ETC adheres to the principle of immutability—"code is law"—long before it became a rallying cry for ETHW.
Why Miners Are Flocking to ETC
Recent data shows a dramatic surge in ETC’s hashrate—up over 100% in just a few months—indicating strong miner migration. Several factors explain this trend:
- Established network security: With years of operation and consistent mining activity, ETC offers greater stability than newer forks.
- Proven infrastructure: Exchanges, wallets, and mining pools already support ETC widely.
- Lower volatility: Compared to ETHW’s speculative price swings, ETC has demonstrated relative price stability.
- Active development: Despite being older, ETC continues to receive protocol upgrades and community-driven innovation.
At the time of writing:
- ETC price: $38.76 (+5.5% over 24 hours)
- ETHW price: $28.18 (-18% over 24 hours)
This contrast highlights not only market confidence but also investor sentiment favoring established assets during periods of uncertainty.

ETHW vs. ETC: A Comparative Breakdown
| Aspect | EthereumPoW (ETHW) | Ethereum Classic (ETC) |
|---|---|---|
| Launch Date | Post-Merge (2022) | Pre-fork (2016) |
| Consensus | Proof-of-Work | Proof-of-Work |
| ChainID | Updated via EIP-3788 | Stable and well-known |
| Hashrate Trend | Volatile, uncertain growth | Surged over 100% recently |
| Price Performance | Declining since launch | Steady upward momentum |
| Community Base | New, miner-focused | Mature, ideologically committed |
| DeFi Integration | Limited | Moderate (growing cautiously) |
While ETHW brings fresh energy and urgency to the PoW space, ETC benefits from longevity, trust, and infrastructure maturity.
Market Sentiment and Miner Behavior
Miners are pragmatic. Their choice isn’t driven solely by ideology but by profitability, ease of integration, and long-term viability.
Current trends suggest that while some miners initially supported ETHW out of loyalty or protest, many are now shifting toward ETC due to better returns and lower operational risks.
Additionally:
- Mining pools such as 2Miners report higher payouts and uptime on ETC.
- Cloud mining services increasingly list ETC as a top-tier option.
- Hardware resellers note increased demand for GPUs optimized for ETC mining algorithms.
This groundswell indicates that practical economics are outweighing emotional allegiance to the ETH brand.
Frequently Asked Questions (FAQ)
Q: What happens to Ethereum miners after The Merge?
After The Merge, Ethereum no longer uses proof-of-work mining. Miners must either switch to another PoW blockchain (like ETC or ETHW), repurpose their hardware, or cease operations.
Q: Can I still mine Ethereum?
No. Ethereum completed its transition to proof-of-stake in 2022. Mining is no longer possible on the Ethereum mainnet.
Q: Is ETHW a scam?
No credible evidence suggests ETHW is a scam. It is a legitimate hard fork aimed at preserving mining. However, its long-term sustainability remains unproven compared to ETC.
Q: Could ETHW and ETC coexist long-term?
Possibly, but competition for limited mining resources makes coexistence challenging. Only the most secure and economically viable chain is likely to survive long-term.
Q: How do replay attacks affect users?
Replay attacks can cause unintended transactions across chains. Users must ensure proper network separation (e.g., using different wallets or replay protection tools).
Q: Which is safer to hold—ETHW or ETC?
ETC is generally considered safer due to its longer track record, larger ecosystem, and resistance to attacks over time. ETHW carries higher risk due to lower liquidity and adoption.

Final Verdict: Who Wins the Mining Race?
While ETHW captured early attention as a symbolic stand for miners’ rights, Ethereum Classic (ETC) has proven to be the more practical and resilient choice. With surging hashrate, stable pricing, and growing infrastructure support, ETC appears better positioned to absorb displaced Ethereum miners.
Ultimately, survival in the post-Merge world depends not on ideology alone—but on security, scalability, and sustained economic incentive. On these fronts, ETC currently holds the edge.
For miners weighing their options, the message is clear: longevity matters. And in the battle between nostalgia and necessity, necessity is winning.
