 * When spending a native P2WSH, the <code>scriptSig</code> MUST be empty, and the witness stack format and signature generating rules are same as P2SH-P2WSH (including the requirement of using compressed public key)

 * P2SH-P2WSHと同様、<code>scripthash</code>は<code>witnessScript</code>をSHA256した値です。
 * Native P2WSHを使用する際は、<code>scriptSig</code>は必ず空で、witnessスタックの形式と署名の生成ルールはP2SH-P2WSHと同じです（圧縮公開鍵を使用する要件含め）。
