F2Pool, Poolin to start Ethereum PoW mining after ETHW mainnet launch

Published at: Sept. 15, 2022

Despite Ethereum’s historic transition to a proof-of-stake (PoS) consensus mechanism, mining pools are increasingly signing up for mining on the upcoming proof-of-work (PoW) version of Ethereum.

EthereumPoW, the community advocating for ETHPoW, or the PoW Ethereum version, has released a list of mining pools that are going to continue mining after the ETHW mainnet launch.

According to EthereumPoW, some major Ethereum mining pools are going to continue mining despite Ethereum’s switch to the eco-friendly PoS consensus mechanism.

At the time of writing, the list of ETHW mining pools composes a total of 19 various mining pools, including F2Pool, Poolin, AntPool, Nanopool, 2miners and EthwMine.

Interestingly, the list includes some Russia-linked pools, including Pool Moscow and BaikalMine, as well as Ukrainian ones, such as UA Pool. EthereumPoW noted that the list is growing as more pools are joining after the mainnet launch.

The mentioned ETHW mining pools apparently make up significant mining capacity. According to data from ETH.BTC.com, F2Pool is the second-largest Ethereum mining pool by blocks after Ethermine, with the year-to-date block share amounting to 15.7%.

Poolin is also a significant contributor, as several Poolin mining pools have a total block share of 8.7%. According to the data, 2miners, Nanopool and AntPool are also notable mining pools, with the annual block share standing at 5%, 3% and 1.5%, respectively.

Together, ETHW mining pools apparently make up more mining capacity in terms of block share than Ethermine, the world’s largest Ethereum mining pool, which mined more than 28% of all Ethereum blocks over the past year.

Unlike F2Pool and Poolin, Ethermine opted to terminate its Ethereum mining pool services due to Ethereum switching on PoS, officially announcing a withdrawal-only mode on Wednesday. Instead, the company has launched a new Ethereum staking service in line with the PoS Ethereum vision of the Ethereum Foundation.

F2Pool did not immediately respond to Cointelegraph’s request for comment. This article will be updated pending new information.

As previously reported by Cointelegraph, Ethereum’s PoS transition became a major issue for Ethereum mining firms as the Ethereum Merge was originally designed to eliminate PoW mining.

The Merge is positioned as a major Ethereum upgrade, aiming to make the cryptocurrency greener and more eco-friendly. According to Ethereum researcher Justin Drake, the Ethereum Merge will reduce worldwide electricity consumption by 0.2%.

Due to Ethereum switching to PoS, Ethereum mining-related firms have been actively searching for solutions to continue mining. For example, cryptocurrency miner Hive Blockchain has been working to replace the mining of Ether (ETH) with other coins.

ETC Group launches crypto ETP based on PoW Ethereum hard fork
Digital asset-backed securities provider ETC Group will continue to rely on Ethereum’s original proof-of-work (PoW) consensus for its current Ethereum exchange-traded product (ETP). ETC Group officially announced on Wednesday the launch of a new Ethereum ETP in response to the upcoming Ethereum Merge. Scheduled to occur in mid-September, the Ethereum Merge is a long-awaited consensus upgrade that is set to move the Ethereum blockchain from mining-based PoW to mining-free proof-of-stake (PoS). ETC Group’s new Ethereum ETP will rely on a forked PoW Ethereum chain, representing a group of miners opposing Ethereum’s switch to PoS. The PoW chain will have a …

Breaking: Historic day for crypto as Ethereum Merge to proof-of-stake occurs
The Ethereum Merge has officially taken place, marking the full transition of the network to proof-of-stake (PoS). On Sept. 15 at 06:44 UTC, the long-awaited Merge saw the merging of the Ethereum Mainnet execution layer and the Beacon Chain’s consensus layer at the Terminal Total Difficulty of 58750000000000000000000, meaning the network will no longer rely on a proof-of-work consensus mechanism. The Ethereum Foundation said the Merge will make the Ethereum network about 99.95% more energy efficient and will set the stage for future scaling solutions, including sharding. Speaking to Cointelegraph, StarkWare President and co-founder Eli Ben-Sasson that “the immediate importance …

What is PoW Ethereum (ETHW), and how does it work?
Ethereum blockchain shifted from a proof-of-work (PoW) to a proof-of-stake (PoS) consensus mechanism on Sept. 15, 2022. Along with this move, ETHPoW, a distinct PoW blockchain (basically the old pre-Merge Ethereum) forked from Ethereum's Merge, became live. This forked version of Ethereum aims to maintain the proof-of-work mining process for ETH miners. Any miner is permitted to add a block to the PoW network with the clear stipulation that the first valid block published is the correct one. In reality, more than one legitimate block is occasionally discovered by the network due to the latency of data propagation, creating numerous …

Ethereum Istanbul Hard Fork Release Date Confirmed By Core Developer
Team lead at the Ethereum (ETH) Foundation Péter Szilágyi has confirmed Dec. 4 as the expected date for the network’s forthcoming Istanbul hard fork. In two tweets posted on Nov. 7, Szilágyi indicated that Istanbul will commence at block 9069000. He provided Geth mainnet node operators with a link to a new maintenance release designed to begin the hard fork’s initialization. Geth is the name given to one of the two most popular clients used to operate nodes on the Ethereum network — the other being Parity, which will update upon the activation of Istanbul but is now in the …

Ethereum Merge and the hefty tax bill you could be in for
Ethereum (ETH) hodlers that don’t play their cards right following the Ethereum Merge may be in for a hefty bill come tax time, according to tax experts. Around Sept.15, the Ethereum blockchain is set to transition from its current proof-of-work (PoW) consensus mechanism to proof-of-stake (PoS), aimed at improving the network’s impact on the environment. There is a chance that The Merge will result in a contentious hard fork, which will cause ETH holders to receive duplicate units of hard-forked Ethereum tokens, similar to what happened when the Ethereum and Ethereum Classic hard fork occurred in 2016.
