Ethereum developers discuss the free data availability issue under the latency execution mechanism.

Gate.io News bot message, Ethereum developer @nero_eth recently published an article discussing the data availability issues under the latency execution (EIP-7886) mechanism.

According to the article, the latency execution mechanism has changed the block validation process. Validators verify the validity of blocks through pre-checks (including nonce, balance, etc.) instead of waiting for transactions to be fully executed. When a transaction fails due to insufficient balance (for example, when transaction A consumes the balance of account B, B’s transaction cannot pay for Gas), this data has already been written into the block and processed by the validators, but the fees have not been paid.

To address the issue of free data availability (Free DA), the article proposes four solutions: optimistic authentication, pre-validation and pre-charging, pre-charging entities, and execution layer no-operation. These solutions ensure that writing data incurs a cost through methods such as pre-deducting fees, block reorganization, or state rollback.
