The ongoing debate around a potential Ethereum Proof-of-Work (PoW) fork has sparked significant discussion across the blockchain community. In response, the ETC Cooperative — a 501(c)(3) public charity founded in 2017 dedicated to advancing the Ethereum Classic (ETC) ecosystem — has issued a public letter addressing key concerns about the viability of such a fork. The message is clear: the proposed ETH PoW chain is unlikely to succeed, and miners would be better served by transitioning to ETC instead.
This article breaks down the core arguments presented in the open letter, analyzes the technical and economic challenges behind forking Ethereum post-merge, and explains why Ethereum Classic remains a sustainable home for PoW miners.
Why the ETH PoW Fork Faces Critical Challenges
At first glance, creating a continuation of Ethereum’s PoW chain may seem technically feasible. However, the reality is far more complex than simply maintaining mining operations. Unlike the original Ethereum/Ethereum Classic split in 2016 — which occurred under vastly different ecosystem conditions — today’s blockchain landscape is deeply interconnected, making clean forks nearly impossible.
1. Technical Complexity of Forking Modern Ethereum
To sustain a PoW version of Ethereum after the Merge, developers must fork not just one but multiple client implementations — including Geth, Erigon, Besu, and Nethermind. Each of these clients requires:
- Removal of Proof-of-Stake (PoS) consensus logic
- Disabling the "difficulty bomb"
- Updating the chain ID to prevent replay attacks
Additionally, mining software must be updated to recognize the new chain ID. While open-source clients can be modified publicly, many mining tools are proprietary. This means developers must persuade closed-source tool creators to support the fork — a major coordination hurdle with no guarantee of success.
2. Lack of Public Development Activity
Transparency builds trust. For any blockchain project to gain credibility, development activity must be visible: GitHub repositories, documentation, release timelines, and community engagement.
As of now, there is minimal public evidence of active development for the proposed ETH PoW chain. No official GitHub organization, no published client binaries, and no technical documentation or tutorials exist. Without these foundational elements, node operators cannot prepare, wallets won’t integrate, and exchanges will hesitate to list.
Given that the Merge is only weeks away, time is running out for meaningful coordination.
The Collapse of DeFi and Stablecoins on a PoW Fork
One of the most critical points raised in the letter is the incompatibility of decentralized finance (DeFi) and stablecoins with a PoW fork.
3. Stablecoins Will Cease to Function
Stablecoins like USDT and USDC are issued by centralized entities that have already declared support for the PoS Ethereum chain. These issuers will not honor balances on a PoW fork. As a result, all stablecoin balances on the forked chain will effectively be worthless from day one.
Since DeFi protocols rely heavily on stablecoins for liquidity, lending, and trading, their functionality collapses without them. Platforms like Aave, Uniswap, and Compound would become unusable — not due to code failure, but because their core assets no longer hold value.
4. dApps Depend on Off-Chain Infrastructure
Decentralized applications (dApps) are not just smart contracts. They depend on:
- Web interfaces
- Backend servers
- Customer support teams
- Documentation and community channels
- Ongoing development and maintenance
None of this infrastructure will automatically carry over to a forked chain. Unless project teams explicitly choose to support both chains — which most won’t due to cost and complexity — dApps on the PoW chain will be inaccessible or broken.
Even worse, many smart contracts have admin keys controlled by project owners. These teams have no incentive to hand over control to unknown fork operators. In fact, they may actively disable contracts on the PoW chain to prevent user confusion and financial loss.
NFTs and Digital Ownership: Another Broken Link
Non-fungible tokens (NFTs) face similar issues. Ownership records may technically exist on the forked chain, but without:
- Marketplaces like OpenSea supporting the new chain
- Metadata servers remaining online
- Project teams validating authenticity
...the NFTs become unverifiable and unsellable. Owning a Cryptokitty on a dead chain means nothing if no platform recognizes it.
Why Ethereum Classic Is the Logical Alternative
The original ETH/ETC split happened in an era before DeFi, NFTs, and complex dApp ecosystems. At that time, continuing to mine ETC required minimal effort — just keep running the same software.
Today, ETC offers:
- A proven, stable PoW blockchain
- Active development and regular network upgrades
- Growing miner adoption as Ethereum transitions to PoS
- Support from mining pools, exchanges, and wallet providers
As stated in the letter:
“ETH miners should transfer to ETC, to maximize their long-term revenue — it’s that simple.”
ETC doesn’t require reinventing infrastructure. It already works.

Frequently Asked Questions (FAQ)
Q: Can a successful Ethereum PoW fork exist alongside PoS Ethereum?
A: Technically possible, but practically unviable. Without stablecoin support, working DeFi protocols, or active dApp maintenance, the forked chain lacks real utility for users.
Q: Will my ETH balance be duplicated on the PoW fork?
A: Likely yes — at launch, you may see a mirrored balance. But without ecosystem support, those tokens will have little to no trading value or usability.
Q: What happens to NFTs after the fork?
A: While NFT ownership data may copy over, they won’t be recognized by major marketplaces or platforms unless those services choose to support the new chain — which most won’t.
Q: Why should miners switch to Ethereum Classic?
A: ETC provides a ready-to-use, secure PoW network with existing infrastructure, exchange listings, and growing miner interest — making it the most sustainable option post-Merge.
Q: Is ETC just a copy of old Ethereum?
A: No. While ETC shares Ethereum’s early history, it has evolved independently with its own roadmap, upgrades (like Phoenix and Agharta), and community-driven governance.
Q: Can developers revive DeFi on a PoW fork later?
A: Theoretically yes, but it would require rebuilding everything from scratch — including liquidity, trust, and integrations. Given limited incentives and resources, this outcome is highly unlikely.
Final Thoughts: A Fork Without Users Is a Chain Without Purpose
The letter concludes with a sobering truth: even if a PoW fork launches successfully, it will likely become a “disaster zone” — full of broken applications, worthless assets, and abandoned projects.
The ecosystem has moved forward. The Merge isn’t just a consensus change; it’s a shift in where value, innovation, and community effort are concentrated.
For miners seeking long-term sustainability, abandoning the idea of an ETH PoW fork and migrating to Ethereum Classic is not just practical — it’s essential.
