PR description
Check the params earlier and move blob validation to a new method
In case CL sends a payload with invalid blob params for a known header, we should return invalid.
Expected Behaviour: return invalid
Actual Behaviour: Returns are valid because we have already seen that payload.
This PR moves the validation earlier in the flow and encapsulates the validation login into a method for readability.
