• validate_4844_header_standalone
  Validates that the EIP-4844 header fields exist and conform to the spec. This ensures that:
• validate_against_parent_4844
  Validates that the EIP-4844 header fields are correct with respect to the parent block. This ensures that the blob_gas_used and excess_blob_gas fields exist in the child header, and that the excess_blob_gas field matches the expected excess_blob_gas calculated from the parent header fields.
• validate_against_parent_eip1559_base_fee
  Validates the base fee against the parent and EIP-1559 rules.
• validate_against_parent_hash_number
  Validates against the parent hash and number.
• validate_against_parent_timestamp
  Validates the timestamp against the parent to make sure it is in the past.
• validate_block_pre_execution
  Validate a block without regard for state:
• validate_body_against_header
  Ensures the block response data matches the header.
• validate_cancun_gas
  Validate that blob gas is present in the block if Cancun is active.
• validate_header_base_fee
  Ensure the EIP-1559 base fee is set if the London hardfork is active.
• validate_header_extradata
  Validates the header’s extradata according to the beacon consensus rules.
• validate_header_gas
  Gas used needs to be less than gas limit. Gas used is going to be checked after execution.
• validate_shanghai_withdrawals
  Validate that withdrawals are present in Shanghai
