Ethereum uses a constant BLOB_BASE_FEE_UPDATE_FRACTION when updating the blob base fee each block, with the proportional change in the fee computed as: math.exp((blob_gas_used - TARGET_BLOBS * GAS_PER_BLOB) / BLOB_BASE_FEE_UPDATE_FRACTION) A new value for this constant has been included in each EIP that changes the target blob gas. It turns out that there is a simple generalization for computing the constant, consistent with both the value set in EIP-4844 and EIP-7691, that would be appropria...
