/**
* Instructions for redeeming a payment.
* <p>Instructions for redeeming a payment.</p>
*
* <p>Bitcoin transactions don't specify what they do directly. Instead <a href="https://en.bitcoin.it/wiki/Script">a
* small binary stack language</a> is used to define programs that when evaluated return whether the transaction
* "accepts" or rejects the other transactions connected to it.</p>
*
* <p>bitcoinj does not evaluate/run scripts. The reason is that doing so requires the connected transactions, ie, all
* transactions, and as a lightweight/SPV client we don't store them all. Instead tx validity is decided by miners
* and we rely purely on the majority consensus to determine if the scripts are valid. This class therefore just lets
* you manipulate and parse them.</p>
* <p>In SPV mode, scripts are not run, because that would require all transactions to be available and lightweight
* clients don't have that data. In full mode, this class is used to run the interpreted language. It also has
* static methods for building scripts.</p>
