# Bitcoin Script

## Definition

Bitcoin Script is the stack-based scripting system Bitcoin uses to define and evaluate conditions under which transaction outputs may be spent.

## What it means in practice

Common address types correspond to standard script templates, while newer constructions such as Taproot add additional ways to express spending conditions.

## How this concept appears in Terenval Wallet

Terenval abstracts normal Bitcoin Script details behind wallet addresses and transaction flows so users do not need to construct scripts manually.

**Important:** A wallet interface simplifies scripts but cannot make an incorrect destination reversible; verify before signing.
