What is EthereumPoW (ETHW)?

TLDR

EthereumPoW (ETHW) is the original proof-of-work blockchain that continued from Ethereum after its transition to proof-of-stake, created to preserve the mining-based ecosystem.

  1. A Forked Legacy – It originated from a community-led hard fork of Ethereum at block 15,537,393 on 15 September 2022, when Ethereum executed The Merge.

  2. Technical Continuity – The network maintains Ethereum's pre-Merge codebase and consensus, relying on miners for security and transaction validation.

  3. Primary Differentiator – It is the principal blockchain that continues Ethereum's proof-of-work legacy, distinguishing it from the now proof-of-stake Ethereum mainnet.

Deep Dive

1. Origin and Purpose

EthereumPoW exists because of The Merge, the event where Ethereum transitioned from an energy-intensive proof-of-work (PoW) system to a proof-of-stake (PoS) consensus. A segment of the community, primarily miners and proponents of PoW, chose to continue the original chain. This hard fork created a separate blockchain where the historical transaction ledger up to the fork block was preserved, but the development path diverged to maintain PoW (CoinMarketCap). Its core purpose is to sustain a version of Ethereum where security and issuance are handled by miners, not stakers.

2. Technical Foundation

Technically, ETHW is a near-replica of the pre-Merge Ethereum network. It uses the same Ethash mining algorithm and supports the same Ethereum Virtual Machine (EVM), meaning decentralized applications (dApps) built for Ethereum can, in theory, run on it. Key modifications were minimal to ensure chain stability; for instance, the difficulty bomb (a mechanism to encourage transition to PoS) was disabled. The native ETHW token is not an ERC-20 standard token but the chain's base asset, used for transaction fees and miner rewards (EthereumPoW FAQs).

3. Key Differentiator: The PoW Ethereum

The primary factor that defines ETHW is its commitment to proof-of-work. While Ethereum (ETH) now operates on PoS, ETHW represents the ideological and technical fork that chose not to adopt this change. This makes it the main continuation of the original Ethereum PoW chain, creating a distinct network for users and developers who prefer or rely on the mining-based model over staking.

Conclusion

EthereumPoW is fundamentally the preserved proof-of-work incarnation of Ethereum, born from a philosophical split over consensus mechanisms. How will the value proposition of a dedicated PoW Ethereum chain evolve within a market increasingly dominated by its staking-based counterpart?
