The impending transition of Ethereum to Proof-of-Stake (PoS) has sparked intense debate, technical innovation, and strategic maneuvering across the blockchain ecosystem. As the network prepares for this historic shift, a growing movement of miners and developers is rallying around preserving the original Proof-of-Work (PoW) chain through a hard fork. This decision isn’t just ideological—it opens up real financial opportunities in trading, arbitrage, and ecosystem development.
In this deep dive, we’ll explore the motivations behind the Ethereum PoW fork, assess the risks and potential of both chains, uncover hidden arbitrage strategies, and examine how users can position themselves ahead of one of the most consequential events in crypto history.
Why Are Miners Forking Ethereum?
At the heart of the Ethereum hard fork lies a fundamental disagreement: what defines a truly decentralized blockchain? While the Ethereum Foundation pushes forward with PoS for scalability and sustainability, many long-time miners argue that PoW remains the gold standard for decentralization and security.
JACK LIAO, veteran miner and coordinator of multiple Ethereum PoW fork initiatives, emphasizes two core reasons for supporting the fork:
- Risk Mitigation: The PoS transition carries inherent technical and regulatory risks. Code vulnerabilities or sudden regulatory actions—such as classifying ETH as a security—could destabilize the entire ecosystem. A PoW fork acts as a "Plan B," ensuring continuity if PoS fails.
- Economic Incentives: The mining industry represents over $10 billion in hardware investment and supports hundreds of thousands of participants globally. Abandoning PoW leaves these stakeholders with stranded assets. Supporting a fork preserves value and offers new revenue streams.
Satoshi_song, developer behind Ethereum Fair (ETF), adds a philosophical dimension: "POW embodies the essence of decentralization—permissionless entry and exit." He argues that while performance improvements are valuable, they shouldn’t come at the cost of core principles like censorship resistance and open participation.

Ethereum Fair vs. ETH1: Divergent Visions for PoW
Two major projects have emerged to carry the torch of Ethereum’s PoW legacy: Ethereum Fair (ETF) and ETH1. Though both aim to preserve mining, their approaches differ.
Ethereum Fair (ETF)
- Recently launched a post-Bellatrix testnet compatible with Sentry Omega v1.10.23.
- Already integrating key DeFi protocols like MakerDAO, Curve, BendDAO, and OpenSea via third-party frontends.
- Focuses on enabling “ecosystem mining”—users can extract value from dormant assets on the forked chain.
- Planning advanced NFT utility layers, including rental, copyright, and multi-creation incentive models.
- Exploring Layer2 integrations to scale the PoW chain sustainably.
ETH1
- Emphasizes backward compatibility and ease of migration for existing dApps.
- Actively engaging second-tier DeFi projects looking to capture early traffic on the new chain.
- Developing PoW 2.0 ("Suitable Workload Proof"), an enhanced consensus mechanism designed to improve performance without sacrificing decentralization.
- Open-sourcing its patent portfolio to defend against future IP-based attacks on open blockchains.
Both teams believe there’s room for coexistence—ETH pursues scalability under PoS, while the PoW forks serve as decentralized backups and alternative innovation hubs.
Potential Risks Facing PoS Ethereum
Despite its promise, PoS Ethereum may face significant challenges:
Regulatory Scrutiny
If regulators classify staked ETH as a security, the entire ecosystem could be forced into compliance frameworks meant for traditional finance. This would undermine Ethereum’s status as a neutral, decentralized platform.
Centralization Risks
Large staking pools like Lido and Coinbase already control over 30% of all staked ETH. With voting power concentrated in few hands, governance could become oligarchic. As JACK LIAO warns: "POS resembles feudal land ownership—closed, static, and resistant to competition."
Competitive Pressure
Once PoS launches, Ethereum will compete directly with other high-performance EVM chains like BSC, Polygon, and Avalanche. Unlike PoW, where hash power is distributed globally, PoS validators are easier to coordinate—and potentially manipulate.

Hidden Arbitrage Opportunities in the Fork
The hard fork creates unique market inefficiencies that savvy traders can exploit.
1. Stablecoin Divergence: USDTW & USDTS
BitCoke Exchange has pre-emptively forked USDT into USDTS (on ETH1) and USDTW (on ETHW). While centralized stablecoins like Tether will only support the PoS chain, their PoW counterparts may gain traction as community-driven meme assets.
Historical precedent exists: LUNA Classic (LUNC) holds a multi-billion dollar market cap despite lacking utility. Similarly, USDTW could appreciate if users treat it as a speculative asset or an “uncensorable” stablecoin alternative.
“POW USDT is stronger than Dogecoin or LUNC—it inherits Ethereum’s massive user base,” says Satoshi_song.
2. DeFi Token Duplication
All ERC-20 tokens existing at the fork snapshot will exist on both chains. However, liquidity won’t automatically follow.
On day one:
- Tokens on PoW chains may trade at steep discounts due to uncertainty.
- Automated Market Makers (AMMs) will list these tokens regardless of fundamentals.
- Traders can buy discounted tokens on PoW DEXs and bridge/sell them on PoS-based platforms—if cross-chain bridges support both chains.
3. NFT Valuation Reset
NFTs also duplicate across chains. But unlike fungible tokens, their value depends on community consensus.
One possible model? Stock-style split valuation. If an NFT worth 1 ETH splits into two copies (one on each chain), each might initially trade near 0.5 ETH. Early arbitrageurs can flip between markets until prices converge.
Will the PoW Chain Survive?
Critics argue the fork is risky:
- Energy consumption: PoW Ethereum uses ~94 TWh/year—comparable to a mid-sized country.
- Carbon footprint: Minting one NFT emits ~200kg of CO₂.
- Economic viability: Without strong DeFi adoption or institutional backing, miner rewards may dwindle.
However, proponents counter that:
- Many miners are switching to renewable energy sources.
- The chain inherits over 80 million smart contracts and 200+ million addresses—creating instant network effects.
- Projects abandoned on mainnet may find new life on PoW forks.
As Loopy Lu from Odaily notes: "Unlike the 2016 ETH/ETC split, today’s ecosystem is vastly more complex—making forks harder to ignore."
How Can Users Profit From the Fork?
For retail participants, here’s how to get involved:
✅ Before the Fork
- Hold ETH in non-custodial wallets (exchanges may delay distribution).
- Stake ETH via liquid staking providers (e.g., Lido) to earn stETH yield while retaining eligibility for forked tokens.
✅ At Fork Time
- Claim your free PoW ETH (e.g., ETHW, ETF) if you held ETH pre-fork.
- Swap USDT for USDTS/USDTW via supported exchanges like BitCoke.
- Explore early liquidity mining opportunities on PoW DEXs like 1inch (already testing on ETF).
✅ After the Fork
- Monitor price discrepancies between identical tokens on PoS and PoW chains.
- Participate in governance or validator pools on PoW networks to earn rewards.
- Deploy capital into emerging Layer2 solutions building atop the new PoW base layer.
Frequently Asked Questions (FAQ)
Q: Will my ETH be duplicated after the fork?
A: Yes. If you held ETH in a personal wallet before the merge, you’ll own equivalent amounts on both the PoS and PoW chains.
Q: Is it safe to use exchanges during the fork?
A: Use caution. Some exchanges may delay withdrawals or only support one chain. For maximum control, use self-custody wallets like MetaMask.
Q: Can I lose money during the fork?
A: Direct loss is unlikely if you hold securely. However, scams often surge during forks—avoid suspicious airdrop links or phishing sites.
Q: What happens to my DeFi positions?
A: Most DeFi protocols on PoS chains will continue normally. On PoW chains, some contracts may be inactive or unverified initially—interact only with audited versions.
Q: Are forked NFTs valuable?
A: Initially, they may trade at discounts. Value depends on whether communities rally around the PoW version. Monitor social sentiment closely.
Q: Could the PoW chain become more valuable than Ethereum?
A: Unlikely in the short term. But as a decentralized fallback option with strong miner support, it could gain long-term relevance—especially under adverse regulatory conditions.
The Future of Decentralization
This hard fork isn’t just about technology—it’s about ideology. It questions whether innovation should mean abandoning proven systems like PoW in favor of efficiency-driven models like PoS.
Projects like Ethereum Fair aren’t trying to replace Ethereum; they’re ensuring that decentralization survives even if mainstream adoption favors convenience over censorship resistance.
As Satoshi_song puts it: "There must always be a POW chain beneath powerful application ecosystems."
Whether you’re a trader seeking arbitrage edges or a believer in open-access blockchains, now is the time to understand—and potentially benefit from—the next chapter in Ethereum’s evolution.
