This corrects some of the script tests which were not properly updated for the differences introduced by Decred as well as adds some additional tests for some updated semantics. Namely: - Correct the redeem script hash of several tests so they fail for the intended reason instead of due to having an invalid script hash - Correct multisig tests to remove the dummy parameter which is not needed by Decred - Change the tests for previously reserved opcodes to discouraged upgradable NOP tests to match their new semantics - Add tests to ensure all discourage NOPs are allowed when in an unexecuted branch - Add tests to ensure all reserved opcodes that are not always illegal are allowed when in an unexecuted branch |

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
$ go get -u github.com/decred/dcrd/txscript
