txscript

Package txscript implements the Decred transaction script language. There is a comprehensive test suite.

This package has intentionally been designed so it can be used as a standalone package for any projects needing to use or validate Decred transaction scripts.

Decred Scripts

Decred provides a stack-based, FORTH-like language for the scripts in the Decred transactions. This language is not turing complete although it is still fairly powerful.

Installation and Updating
