Legacy transaction deep copy code mandated by the Bitcoin protocol caused large amounts of data to be copied needlessly. If the optimization for SigHashAll is set in chaincfg/params.go, these extra copies are avoided by directly writing the pkScript and decorations to a buffer and then hashing to get a witness hash, while using the cached hash for the prefix. Fixes #126. |

txscript
Package txscript implements the decred transaction script language. There is a comprehensive test suite. Package txscript is licensed under the liberal ISC license.
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 langauge for the scripts in the decred transactions. This language is not turing complete although it is still fairly powerful.
