- Validates that the EIP-4844 header fields exist and conform to the spec. This ensures that:
- Validates that the EIP-4844 header fields are correct with respect to the parent block. This ensures that the

field matches the expectedexcess_blob_gas
calculated from the parent header fields. - Validates the base fee against the parent and EIP-1559 rules.
- Validates against the parent hash and number.
- Validates the timestamp against the parent to make sure it is in the past.
- Validate a block without regard for state:
- Ensures the block response data matches the header.
- Validate that blob gas is present in the block if Cancun is active.
- Ensure the EIP-1559 base fee is set if the London hardfork is active.
