According to Planet Daily, EthHub co-founder Anthony Sassano (sassal.eth) said that the Ethereum Dencun upgrade will be activated on the Holesky testnet, which is less than 12 hours away. This is the last testnet fork before the mainnet, and the mainnet upgrade activation date will be determined at tomorrow's AllCoreDevs conference call, which is expected to be in early to mid-March. EIP-4844 is coming.
