Advanced Transactions and Scripting

Introduction

In the previous chapter, we introduced the basic elements of bitcoin transactions and looked at the most common type of transaction script, the P2PKH script. In this chapter we will look at more advanced scripting and how we can use it to build transactions with complex conditions.

First, we will look at multisignature scripts. Next, we will examine the second most common transaction script, Pay-to-Script-Hash, which opens up a whole world of complex scripts. Then, we will examine new script operators that add a time dimension to bitcoin, through timelocks. Finally, we will look at Segregated Witness, an architectural change to the structure of transactions.
