Post by: Coding Enthusiast on January 29, 2019, 02:15:34 PM Previous outputs which this transaction is spending weren't "scripthash", they were Pay To Witness Pubkey Hash[1]. That is why the signature (or more precisely the scriptsig) is "transferred" elsewhere in a field called "witness" instead of it being in its usual place after the outpoint.
