On May 6th, @nero_eth, an Ethereum developer, discussed "Delayed Execution and Free DA Issues". Delayed Execution (EIP-7886) changes the verification process: the validator verifies the validity of the block through pre-checks (e.g. nonce, balance) before the transaction is fully executed. If a transaction fails due to insufficient balance during execution (e.g., transaction A depletes account B's balance, causing transaction B of B to fail to pay gas), its data has been written to the block and processed by the validator without payment.
This leads to the problem of Free DA: invalid transactions occupy the data availability resources on the chain, and the verifier is not compensated. This paper proposes four solutions: optimistic authentication, pre-verification and pre-charging, and pre-charging entity and execution layer no-operation, which ensure the cost of data writing through withholding fees, block reorganization or state rollback, and prevent network congestion and economic injustice caused by Free DA.
