EIP-8141 adopts the two-dimensional gas model of EIP-8037 and activates on a fork that also includes EIP-7778 (Amsterdam). EIP-8037's "Integration with EIP-7778" section accounts the block execution dimension before the storage refund, so a refund lowers the payer's cost without freeing the block capacity the transaction occupied — the DoS bound EIP-7778 exists to keep.
The current EIP-8141 settlement accounts
block_execution_gas_usedfromgas_used_after_refund(post-refund), so a frame transaction re-opens the refund-based block-limit circumvention that EIP-7778 closes for every other transaction type on the same fork.This PR:
7778torequires:;gas_used_before_refund(block_execution_gas = max(gas_used_before_refund - tx_state_gas, calldata_floor_gas)), mirroring EIP-8037's EIP-7778 integration;cumulative_gas_usedon the post-refundgas_usedunchanged; the state dimension stays net, since a state-gas refill is not a refund in the EIP-7778 sense.Is the omission of the EIP-7778 integration a spec bug rather than an intended departure? EIP-8141's only documented departure from EIP-8037 is the calldata-floor payment rule; the refund/block-accounting integration appears to have been carried over from the pre-7778 form.
