Ethereum's switch to proof-of-stake in September 2022 — better known as The Merge — was supposed to be the final goodbye to GPU mining on the world's largest smart-contract chain. A vocal faction of miners disagreed. Within days, they launched EthereumPoW (ETHW), a hard fork that preserved the original proof-of-work consensus and kept the pre-Merge transaction history intact. The pitch was simple: miners who had poured billions into rigs shouldn't lose their livelihood because developers wanted to slash energy consumption.

What Is ETHW and Why Was It Created?

ETHW positions itself as the "true" continuation of the Ethereum that existed for seven years before the Merge. It kept the familiar 0x address format, retained full EVM compatibility, and even implemented replay protection so that transactions on one chain wouldn't accidentally trigger on the other. For a brief window in late 2022, it looked like a credible challenger — at least on paper.

Whether that pitch resonated with anyone beyond the original mining pool is a different story, and the answer has changed dramatically over time. The project was spearheaded largely by Chinese mining operations that had dominated Ethereum's hashrate before the Merge. Their argument carried weight inside certain Telegram channels, but struggled to break through to Western developers, institutional liquidity providers, or retail traders outside Asia.

Within weeks, ETHW's social media footprint shrank, its token unlocks trickled into thin order books, and the project settled into a long, quiet fade.

How ETHW Diverged From Ethereum Technically

Beyond the obvious consensus swap, ETHW made a handful of deliberate protocol changes to distance itself from its parent chain. The most notable was removing the difficulty bomb that was scheduled to make mining unprofitable on legacy Ethereum. Without it, miners can still produce blocks efficiently, and the chain doesn't risk the gradual stalling that originally pushed Ethereum toward proof-of-stake.

ETHW also tweaked EIP-1559's fee-burn mechanism in its original form, meaning the entire base fee flows to miners rather than being partially destroyed. The team argued this better incentivizes the network's security providers and creates a cleaner monetary policy. Other smaller adjustments modified uncle block rewards and gas mechanics to keep older GPU rigs competitive with newer hardware.

Critically, ETHW inherited every smart contract and token balance from Ethereum up to the Merge block. That makes it technically EVM-equivalent — developers can deploy the same Solidity code without modification.

The Replay Protection Question

One of the trickiest parts of any hard fork is preventing replay attacks, where a transaction signed on one chain gets maliciously rebroadcast on the other. ETHW's developers addressed this by altering the chain ID, ensuring that wallets and node software could distinguish between the two networks. It's a small but essential piece of plumbing that separates a serious fork from a fragile copycat.

The catch with all this technical fidelity? Liquidity, users, and validators all had to be rebuilt from scratch — and that has proven to be the hardest problem of all.

The Exchange Problem and Liquidity Drought

Almost immediately after launch, ETHW ran into the cold reality of crypto markets: exchanges call the shots on which chains survive. Major platforms like the biggest global spot exchanges never listed the token, citing low liquidity and concerns about the long-term viability of proof-of-work forks. A handful of smaller exchanges — primarily serving Asian retail traders — did pick it up, but trading volume remained a trickle compared to Ethereum's daily throughput.

This created a vicious cycle that's hard to escape:

  • Low volume discourages dApp developers from deploying
  • Few dApps means there's no reason for users to bridge funds over
  • No users means exchanges eventually delist or freeze withdrawals
  • Delistings kill the remaining volume and trigger sell pressure

By late 2023, ETHW had largely faded from mainstream conversation. The chain still produces blocks, miners still earn rewards, and a stubborn community still holds bags — but the project no longer commands the headlines it briefly enjoyed during the Merge mania.

Is There Any Reason to Care About ETHW Today?

Honest answer: probably not for most people. But the fork remains a fascinating case study in crypto governance and the political economy of consensus changes. When a network as large as Ethereum changes its fundamental rules, there will always be a minority who refuse to follow — and ETHW is what that resistance looks like in practice.

There are a few niche scenarios where ETHW still earns attention:

  • Airdrop hunters occasionally receive unexpected ETHW balances when interacting with old Ethereum contracts that predate the Merge
  • Miners with depreciated GPU hardware can still generate a small yield by pointing rigs at the chain, even if profitability is marginal
  • Researchers and historians study ETHW as a real-world test of hard-fork sustainability in a post-Merge landscape

Speculators sometimes revive interest during market-wide rallies or Ethereum-related news cycles, but these tend to be short-lived pumps on illiquid order books rather than signs of structural recovery. Treat any sudden price spike with skepticism, and remember that thin liquidity cuts both ways — getting out can be just as hard as getting in.

Key Takeaways

EthereumPoW (ETHW) is the proof-of-work hard fork that emerged from The Merge, championed by miners who refused to give up GPU-based block production. It inherited Ethereum's full state and EVM compatibility but lost the battle for legitimacy, liquidity, and developer mindshare within months of launch.

Today, ETHW survives as a curiosity rather than a contender — a reminder that technical viability alone doesn't guarantee a chain's success. Without exchanges, users, and apps, even a "true" Ethereum is just an empty ledger with extra steps. For most traders and builders, sticking with the main Ethereum network remains the obvious choice, while ETHW lives on as a footnote in crypto history.
