EIP-7706

EIP-7706, authored by Vitalik Buterin, proposes a separate gas type for transaction calldata with its own basefee and per-block gas limit. The proposal argues that this would bound the theoretical maximum calldata per block without making calldata scarcer on average, since basic economic analysis suggests calldata would become considerably cheaper. It adds a new transaction type that carries max fees and priority fees as three-item vectors covering execution, blob and calldata gas, and it sets the calldata gas target at 187,500 bytes per block, about twice the current average. The EIP is in Draft status and is categorized as a Core, Standards Track change requiring EIP-1559 and EIP-4844.
