Chapter 12: Embedding Bitcoin Scripts in P2SH & P2WSH Transactions

Bitcoin Script moves down several levels of abstraction, allowing you to minutely control the redemption conditions of Bitcoin funds. But, how do you actually incorporate those Bitcoin Scripts into the transactions you've been building to date? The answer is a new sort of Bitcoin transaction, the P2WSH (formerly: the P2SH, which we'll also meet along the way).
