As Ethereum's Merge upgrade approaches, discussions about the future of Ethereum miners intensify. Chandler Guo, a prominent crypto advocate, recently sparked debates on forking Ethereum to maintain a Proof-of-Work (PoW) chain—dubbed ETH-PoW. This analysis explores two primary options for miners: migrating to other PoW networks or orchestrating a hard fork.
Option 1: Migrating to Other PoW Networks
Ethereum Classic (ETC) as the Leading Contender
- Recent Trends: ETC’s price surged ~170% in a month, outpacing ETH’s 52% gain. Its hashrate grew by 19%, compared to Ethereum’s 9.3%.
Challenges:
- Hashrate Disparity: Ethereum’s hashrate (~935 TH/s) dwarfs ETC’s (~25 TH/s). A mass migration would spike mining difficulty, slashing profits.
- Economic Viability: ETH’s price is 42× higher than ETC’s, further eroding miner ROI.
- Ecological Limits: ETC hosts just 3 DeFi projects, raising sustainability concerns.
Other PoW Networks: Limited Capacity
- Ravencoin (2.6 TH/s) and Monero (2.8 GH/s) lack the infrastructure to absorb Ethereum’s hashrate.
- Centralization Risks: Smaller networks face 51% attack threats if dominated by a few large miners.
Option 2: Forking Ethereum to ETH-PoW
Technical and Ecological Hurdles
- Complexity: Unlike BTC/BCH forks, Ethereum’s ecosystem involves thousands of interoperable DApps, requiring coordinated support.
- DeFi’s Critical Role: Protocols like Aave and Uniswap would likely follow stablecoin issuers (e.g., USDC/USDT). If Circle (USDC) backs the PoS chain, ETH-PoW’s "forked" stablecoins would lack value.
- Historical Precedent: Ethereum Classic’s stagnation post-fork (without Vitalik’s support) raises doubts about ETH-PoW’s longevity.
FAQs
Q1: Will mining ETC be profitable post-Merge?
A: Unlikely. ETC’s lower price and smaller ecosystem may render mining unviable for most miners.
Q2: Can ETH-PoW attract developers?
A: Without core Ethereum devs, building a competitive ecosystem is an uphill battle.
Q3: What’s the biggest risk for ETH-PoW?
A: Liquidity collapse if major stablecoins and DeFi protocols reject the fork.
Conclusion
Both paths—migration or fork—present significant challenges. While PoW alternatives offer temporary relief, their long-term viability is questionable. ETH-PoW’s success hinges on broad ecological support, which seems improbable given Ethereum’s entrenched PoS transition. The crypto community awaits innovative solutions to address this looming transition.
