 =====Committing to the ScriptSigs Hash=====
 
 The scriptsig in a segwit transaction must be exactly empty, unless it is a P2SH
 segwit transaction in which case it must be only the exact redeemscript. P2SH is incompatible
 (unless the P2SH hash is broken) with CHECKTEMPLATEVERIFY because the template hash must commit

 To prevent malleability when not using a segwit input, we also commit to the
