Bitcoin Scripting

Bitcoin scripts act like the instructions and tools needed to open a box and access the funds inside. These scripts are essentially programs written in a special language built into the Bitcoin protocol.

Defining Locking Scripts and Spending Conditions

A locking script acts as the intricate lock on this vault, specifying the conditions that must be met before someone can spend the bitcoins within. This type of script is referred to as the scriptPubKey because it often involves a public key or a Bitcoin address (derived from a public key hash). However, the possibilities extend far beyond, allowing for more complex spending conditions.
