What is TxIn’s sequence?
What are the logical conditions that would require me to change a sequence number?
Suppose there is this transaction
txid: abcdefghi... sequence:1 input:1someVanityName output:1otherVanityName ...
... and the people who mutually created this TX decide to revise some information. Perhaps change the amount, or lock duration. Since a tx number will change once the sequence # changes, (or any change for that matter) when should I logically change the sequence number?
...when I change the amount or lock duration?
...when I change the output script?
...when I add / remove addresses from the input portion of the tx?
...when I add / remove addresses from the output portion of the tx?
Eventually I may modify the transaction in such a way it has no resemblance to the original tx... and may apply to a whole different set of circumstances.
When should I increment the sequence number versus creating a new tx?
