Abstract
This EIP imposes that the price of the targeted number blobs TARGET_BLOB_GAS_PER_BLOCK * base_fee_per_blob_gas stays above the price of a simple blob-carrying transaction TX_BASE_COST * base_fee_per_gas. This ensures that the blob fee auction can function properly, because the equilibrium always forms relative to the fee that carries the price signal. The proposed if statement to check fee parity in calc_excess_blob_gas() represents a neutral, simple, and future-proof resolution to current blob fee auction idiosyncrasies.
