What’s new? The developers of a potential Ethereum hard fork on the Proof of Work (ETHW) consensus algorithm have published the code containing the removal of the EIP-1559 proposal, according to which part of the transaction fees in the blockchain are destroyed. However, the crypto community found a serious flaw in the code. Analyst Colin Wu wrote on Twitter that the developers' error could roll back all blocks to the state prior to the London hard fork, which was made in August 2021. The team later released the corrected code.

ETHW team released the first code yesterday, including the removal of EIP1559 and distribute to the miners. People found a loophole which will roll back all blocks to before the London fork. Team released the patch code for the vulnerability this morning. https://t.co/uV4T5a3OUI— Wu Blockchain (@WuBlockchain) August 16, 2022

What is known about EIP-1559? This upgrade was part of the London hard fork. It was supported by developers and users, but some of the miners were against it, because their earnings depend on the network congestion, with the increase of which the fees increase.

Earlier, the developers of the PoW hard fork published a manifesto of the digital asset. Among the main points were the rejection of EIP-1559, no pre-mining and inflation.

On August 11, the Goerli testnet on the Ethereum network was successfully switched to the Proof of Stake (PoS) consensus algorithm in a merge with another Prater testnet. A major blockchain upgrade, which may result in a PoW hard fork, is expected in mid-September.
