|
Whether a block is valid or not is a bit subtle, it's defined by presence of
|
|
blockHeader, transactions and uncleHeaders fields. If they are missing, the block is
|
|
invalid and we must verify that we do not accept it.
|
|
|
|
Since some tests mix valid and invalid blocks we need to check this for every block.
|
|
|
|
If a block is invalid it does not necessarily fail the test, if it's invalidness is
|
|
expected we are expected to ignore it and continue processing and then validate the
|
|
post state.
