Foresight News reported that Ethereum core developer timbeiko. eth tweeted that "Pectra was launched on Holesky on Monday, and an EL vulnerability caused chain splits, resulting in a small number of valid chains and reducing network health. Holesky verification personnel need to take action as soon as possible, and some Sepolia users need to upgrade their clients. Tonight, a large-scale slash will be conducted on the Holesky testnet to ultimately determine the correct blocks on the chain, which may last for 2 to 3 weeks until the weight of validators affected by the slash drops below 33% of the entire network. In addition, the upgrade time for the Sepolia testnet will not change, providing a longer testing period for the mainnet upgrade
