Ethereum client developers confirmed on Thursday that the expected Dencun upgrade will not be implemented in a network hard fork before the end of 2023. Last month, when the new Holešky testnet was successfully launched later than planned, it was unanimously believed that it was unlikely to complete the upgrade before the December holidays. Anonymous Prysm developer Potuz confirmed on today's core developer conference call that it is impossible to fork the mainnet in 2023. He pointed out that in the past few months, there has been a consensus issue among the 10 developer networks (devnets) that have launched test upgrades so far, and added that "none of them have progressed smoothly."
