ChainCatcher message, Ethereum developer @nero_eth discusses delayed execution (EIP-7886) and data availability optimization proposals. This proposal aims to improve the block validation mechanism, allowing validators to confirm block validity through preliminary checks before transactions are fully executed. The research team has proposed various implementation solutions, including optimistic validation, pre-validation with pre-charging, and Coinbase-based front charging. The new mechanism is expected to enhance network efficiency, but it needs to balance factors such as user experience, construction complexity, and fork selection. This research has received feedback from several core Ethereum developers and is currently still in the design optimization phase.
