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 Together with this transfer, ETHPoW, a definite PoW blockchain (mainly the outdated pre-Merge Ethereum) forked from Ethereum’s Merge, turned dwell. This forked model of Ethereum goals to take care of 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 revealed is the right one. In actuality, multiple reliable block is often found by the community because of the latency of knowledge propagation, creating quite a few branches of the blockchain known as a fork.

This text will focus on 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 decreased the requirement for miners. It changed them with validators who stake Ether (ETH) relatively than utilizing pricey and energy-intensive gadgets to safe the community, considerably growing the cryptocurrency’s power effectivity. Nevertheless, 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 methodology 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, nevertheless it was already in use by a Bitcoin Money testnet. In consequence, the MetaMask cryptocurrency wallet customers confronted points because the Chain ID, appearing as an identifier, couldn’t differentiate between two separate blockchains.
Chain IDs will 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 staff behind ETHW ignored the problem. Regardless of this, crypto exchanges like Binance and Coinbase confirmed help for ETHW. As an illustration, Binance introduced its ETHW mining pool, stating that it is going to be topic to the identical assessment course of as different cryptocurrencies.

How does PoW Ethereum (ETHW) work?
The preliminary model of the Ethereum community (i.e., Ethereum Basic) was based mostly on the PoW consensus methodology. Nevertheless, this model was laborious forked to safe the community on account of the DAO hack. EthereumFair and EthereumPOW are the opposite two laborious forks of the original Ethereum blockchain that may proceed to make use of proof-of-work mining.
Proof-of-work cryptocurrencies like Bitcoin (BTC) are promoted as a censorship-resistant, trustless sort of digital cash created after one individual or a small group of individuals solve a mathematical puzzle and suggest a brand new block. Nevertheless, 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 may also proceed to resolve 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 right way to purchase PoW Ethereum (ETHW)
Crypto buying and selling platforms like Crypto.com and exchanges comparable to Coinbase and Binance are examples of some locations the place ETHW supporters should purchase proof-of-work Ethereum tokens.
As an illustration, Binance formally launched Binance Pool’s fee-free Ethereum ETHW mining service that provides ETHW withdrawals for a restricted time. Nevertheless, please observe that ETHW deposits usually are not doable. On Binance Convert, customers can sell ETHW in opposition to BUSD and USDT.
The essential steps required to purchase ETHW in your chosen platform embrace:
- Create an account in your chosen platform/trade and confirm your id.
- After the id 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 desire proof-of-work as a result of they’ve already invested in costly mining gear, and the shift to a PoS community will go away them with no income.
The right way to retailer PoW Ethereum (ETHW)?
{Hardware} or software program wallets will 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 homeowners with software program wallets retain custody of their non-public keys versus permitting them to be held by the trade.

Customers who’re principally away from their PCs might select cell wallets to retailer ETHW or every other cryptocurrency. Nevertheless, the unique proprietor might lose funds if the gadget 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 fingers of unauthorized customers, the proprietor’s ETHW can’t be recovered.
ETH vs. ETHW
After the Merge, the Ethereum community was break 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 will probably be added to the blockchain by way of the staking course of. Then again, the proof-of-stake blockchain just isn’t a substitute for the unique Ethereum blockchain however relatively 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 gear, the PoS consensus methodology 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 consequence within the full cessation of PoW mining.
