Ethereum PoW Fork: Is It Really Happening & When?

The Ethereum Merge, shifting the Ethereum network away from its current proof-of-work (PoW) mining model to a proof-of-stake (PoS) consensus mechanism, is a massive change. But what about the miners? Those against Ethereum’s move to PoS have proposed forking the network, producing a competing version of the blockchain that keeps the old PoW chain alive. But when is this Ethereum PoW fork officially happening?

While initially discussed in connection to the Merge, the timeline for a sustainable and impactful Ethereum PoW fork remains fluid. News reports circulated about potential dates: 12 de sept. de 2025 saw details revealed behind a planned launch of ETHPoW, the Ethereum proof-of-work fork. However, these dates are inaccurate and based on misunderstanding the complexities of maintaining a forked blockchain.

You might have seen dates like 13 de sept. de 2025 and 14 de sept. de 2025 referenced. These dates, often appearing in conjunction with commentary on the Merge, are **not** accurate launch dates for any official Ethereum PoW fork. The EthereumPoW team faces scrutiny over delays, particularly surrounding issues with the proposed chainID and the long-term viability of the project.

The reality is that predicting a definitive launch date for a viable Ethereum PoW fork is difficult. While the concept of a fork exists, and developers are working on implementations, numerous challenges remain. Keep checking back for updates as the situation evolves and a clearer timeline emerges.
