The CSV consensus rules dictate that the opcode fails when the transaction version is not at least version 2, however that only applies if the disable flag is not set in the sequence. This is not an issue at the current time because we do not yet enforce CSV at a consensus level, however, I noticed this discrepancy when doing a thorough audit of the CSV paths due to the ongoing work to add full consensus-enforced CSV support. As a result, this must be merged prior to enabling consensus enforcement for CSV or it would open up the potential for a hard fork. |

Package txscript implements the bitcoin 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 bitcoin transaction scripts.
Bitcoin Scripts
Bitcoin provides a stack-based, FORTH-like language for the scripts in the bitcoin transactions. This language is not turing complete although it is still fairly powerful. A description of the language can be found at https://en.bitcoin.it/wiki/Script
