PoW Ethereum or ETHW is a forked model of the Ethereum blockchain created by a Chinese language miner after the Merge of the execution and consensus layers.

The way to crypto

Ethereum blockchain shifted from a proof-of-work (PoW) to a proof-of-stake (PoS) consensus mechanism on Sept. 15, 2022. Together with this transfer, ETHPoW, a definite PoW blockchain (mainly the previous pre-Merge Ethereum) forked from Ethereum’s Merge, grew to become stay. This forked model of Ethereum goals to keep up the proof-of-work mining process for ETH miners.

Any miner is permitted so as to add a block to the PoW community with the clear stipulation that the primary legitimate block printed is the proper one. In actuality, a couple of professional block is sometimes found by the community because of the latency of information propagation, creating quite a few branches of the blockchain known as a fork. 

This text will talk about the proof-of-work Ethereum fork, the historical past of PoW Ethereum and the variations between ETH and ETHW. 

What’s ETHPoW (ETHW)?

The long-awaited “The Merge” improve for Ethereum lowered the requirement for miners. It changed them with validators who stake Ether (ETH) slightly than utilizing expensive and energy-intensive units to safe the community, considerably rising the cryptocurrency’s power effectivity. Nonetheless, forward of the Merge, a hard fork of the Ethereum community, known as ETHW, which nonetheless makes use of the PoW consensus mechanism, was created, resulting in a triumph for ETH miners. 

However who’s behind ETHW? Chinese language miner Chandler Guo opposed the PoS consensus technique and launched the PoW-based Ethereum blockchain. Though creating the PoW Ethereum chain might be a victory for miners over stakers, ETHW customers suffered accessibility points. 

The chain ID that ETHPoW used is 10001, but it surely was already in use by a Bitcoin Money testnet. Because of this, the MetaMask cryptocurrency wallet customers confronted points because the Chain ID, performing as an identifier, couldn’t differentiate between two separate blockchains.

Chain IDs may be chosen at will as a result of there isn’t a central repository or registry, however pre-hard fork testing would have discovered the contradiction, whereas the workforce behind ETHW ignored the difficulty. Regardless of this, crypto exchanges like Binance and Coinbase confirmed assist for ETHW. As an example, Binance introduced its ETHW mining pool, stating that it is going to be topic to the identical overview course of as different cryptocurrencies.

How does PoW Ethereum (ETHW) work?

The preliminary model of the Ethereum community (i.e., Ethereum Traditional) was primarily based on the PoW consensus technique. Nonetheless, this model was onerous forked to safe the community attributable to the DAO hack. EthereumFair and EthereumPOW are the opposite two onerous forks of the original Ethereum blockchain that can proceed to make use of proof-of-work mining.

Proof-of-work cryptocurrencies like Bitcoin (BTC) are promoted as a censorship-resistant, trustless kind of digital cash created after one individual or a small group of individuals solve a mathematical puzzle and suggest a brand new block. Nonetheless, to forestall any small group of miners from enacting guidelines that might weaken the resistance to censorship, many non-colluding miners should be processing transactions.

Equally, to cease anybody from abusing the system, ETHW miners can even proceed to unravel arbitrary mathematical challenges to validate transactions and mine new tokens. In return, they are going to be rewarded with ETHW, the native asset to the ETHPoW chain.

The way to purchase PoW Ethereum (ETHW)

Crypto buying and selling platforms like and exchanges corresponding to Coinbase and Binance are examples of some locations the place ETHW supporters should purchase proof-of-work Ethereum tokens.

As an example, Binance formally launched Binance Pool’s fee-free Ethereum ETHW mining service that gives ETHW withdrawals for a restricted time. Nonetheless, please notice that ETHW deposits aren’t attainable. On Binance Convert, customers can sell ETHW towards BUSD and USDT.

The essential steps required to purchase ETHW in your chosen platform embody:

  • Create an account in your chosen platform/alternate and confirm your identification.
  • After the identification verification course of is profitable, deposit funds.
  • Customers can go to the buying and selling part and purchase ETHW after their account has been funded.

However why do folks use PoW Ethereum? Proof-of-stake critics want proof-of-work as a result of they’ve already invested in costly mining tools, and the shift to a PoS community will depart them with no income. 

The way to retailer PoW Ethereum (ETHW)?

{Hardware} or software program wallets may be utilized to retailer ETHW. {Hardware} wallets provide extra safety than software program wallets because the funds are saved offline utilizing wallets like Ledger Nano S. Crypto house owners with software program wallets retain custody of their personal keys versus permitting them to be held by the alternate.

Customers who’re principally away from their PCs could select cellular wallets to retailer ETHW or some other cryptocurrency. Nonetheless, the unique proprietor could lose funds if the machine is contaminated with malware. Alternatively, one can use paper wallets that retailer private and public keys and QR codes on a bit of paper. Once more, if the doc containing this info is misplaced or falls into the arms of unauthorized customers, the proprietor’s ETHW can’t be recovered. 


After the Merge, the Ethereum community was cut up into two variations: ETH, which makes use of the PoS consensus algorithm, and ETHW, which makes use of the older PoW algorithm. That stated, ETHW miners obtain rewards within the type of Ethereum tokens by fixing difficult mathematical puzzles, whereas validators might want to stake ETH for income functions.

ETHW attracts miners as a result of with out a proof-of-work consensus mechanism, they could go bankrupt as new tokens shall be added to the blockchain through the staking course of. However, the proof-of-stake blockchain is just not a substitute for the unique Ethereum blockchain however slightly a merge of the execution (mainnet) and consensus (Beacon chain) layers.

The variations between ETH and ETHW are said within the desk under:


Way forward for PoW Ethereum

The PoW consensus scheme’s incentive construction requires the community’s miners to carry out many hashes to acquire the primary usable block hash, leading to unsustainable power use. Moreover, the consensus mechanism adjusts the block hash issue upward because the community’s processing energy grows, resulting in the next network-wide hash fee.

Furthermore, the power utilized by unsuccessful miners goes to waste, main Ethereum to maneuver to a proof-of-stake consensus mechanism. Though ETHW attracts miners as a result of they’ve already invested in {hardware} mining tools, the PoS consensus technique is much less energy-intensive and permits networks to scale inexpensively. 

Proof-of-stake remains to be in its infancy, probably revolutionizing blockchain safety and rendering mining out of date. However it’s but to be seen if PoS consensus algorithms will outcome within the full cessation of PoW mining.
