Fixes for 4884 tests in hive: simulators/eth/pyspec

[spencer-tb]

Adds some small changes required to get all our current 4844 execution-spec-tests to pass within the pyspec hive simulator. This simulator simply runs all of our fixtures against clients using the EngineAPI. More info on how to run it below within "Notes on testing".

Changes

• Skips the ExcessDataGas calculation within BlockProcessor for genesis blocks, where the block number is zero (prevents SYNCING).
• Updates the ChainSpec to use the ExcessDataGas field input from the genesis block as opposed to using a value of zero (prevents SYNCING).
• Moves the KZG hash version check from the transaction execution payload validation step into the transaction network validation step within TxValidator (prevents VALID payloads being recognized as INVALID).

Notes on testing

This has not been tested internally within Nethermind.

These changes allow all of our 4844 execution-spec-tests to pass on hive using the pyspec simulator. If you want to try it out yourself you can use this testing branch -> here.

Note that the branch is experimental for the time being but you should be able to run the tests by 1) re-building hive after pulling in the changes, 2) using the following command:

./hive --sim ethereum/pyspec --client "./nethermind.json" --docker.nocache nethermind --sim.limit /4844
