The Ethereum Foundation stated that its "Trillion Dollar Security" plan is exploring the transaction result constraint mechanism (Native Transaction Assertions), which allows transactions to attach constraints on the final execution results, and checks status changes such as balances, contract storage, codes, and events after execution; if the final results do not meet the preset rules, the transaction will be rolled back. This mechanism is designed to solve the problem of bias in transaction intentions or results that cannot be avoided by relying solely on signatures, Clear Signing, and transaction simulation. EIP-7906 is one of the candidate implementations and has not yet been determined to be included in the Ethereum upgrade.
