 ### Gas price of blobs (Simplified version)
 
+***WARNING:` This is only for testing***

 For early draft implementations, we simply change `get_blob_gas(parent)` to always return `SIMPLE_GAS_PER_BLOB`.
 
 ### Gas accounting (Full version)
 
 We introduce data gas as a new type of gas. It is independent of normal gas and follows its own targeting rule, similar to EIP-1559.
-We use the `excess_blobs` header field to store persistent data needed to compute the data gas price. For now, only blobs are charged for in data gas. In the future this could be extended to also cover calldata (at a different relative gas cost).

 Like EIP-1559, it's a self-correcting formula: as the excess goes higher, the `data_gasprice` increases exponentially, reducing usage and eventually forcing the excess back down.
 
 The block-by-block behavior is roughly as follows.
-If in block `N`, `data_gasprice = G1`, and block `N` has `X` blobs, then in block `N+1`, `excess_blobs` increases by `X - TARGET_BLOBS_PER_BLOCK`,
+If block `N` contains `X` blobs, then in block `N+1` `excess_blobs` increases by `X - TARGET_BLOBS_PER_BLOCK`,
 and so the `data_gasprice` of block `N+1` increases by a factor of `e**((X - TARGET_BLOBS_PER_BLOCK) / DATA_GASPRICE_UPDATE_FRACTION)`.
 Hence, it has a similar effect to the existing EIP-1559, but is more "stable" in the sense that it responds in the same way to the same total usage regardless of how it's distributed.
