As discussed in recent 4844 implementers calls, this proposes to add optional fields for blobGasUsed and blobGasPrice to the transaction receipt object specific to 4844 blob transactions.

looks good, should it also not be part of the encoding as noticed by @jochem-brouwer

I don't think we'd want it encoded since the values can be derived from protocol rules. The field is being added more for convenience. And to that end, I wonder if the value of data_gasprice should be in there too, in order to be able to conveniently compute the gas cost component incurred by the blobs. Without this you'd have to re-implement get_data_gasprice from the spec and hope the parameters never change.

This change seems fine, but there are other large changes to the RPC that need to be made for cancun so I am going to hold off merging this until that solidifies. We don't really have much ability on execution rpc side of things to denote fork-related info.

Is this change only for RPC and not for receipts RLP in devp2p?

That was my understanding from the discussion on the last implementers call.

Can we add dataGasPrice too? I think without it this change isn't very helpful. Having both fields allows one to calculate total gas cost easily from the tx receipt in a way that will be forward compatible with any 4844 parameter tweaks:

(effectiveGasPrice * gasUsed) + (dataGasPrice * dataGasUsed)
