Q4/ What is the use of having a signature in a transactional structure such as question 1? Suppose a node in the network wants to forge the content of a transaction in its favor so that by verifying the signature this forgery can not be detected (of course, by checking other cases can be). What fields of the transaction should this person change and why? Given that the transaction can not be detected by verifying it is fake, suggests what information to check to determine if the transaction is fake?
