Package btcscript implements the bitcoin transaction scripts. There is
a comprehensive test suite. test_coverage.txt
contains the current
coverage statistics (generated using gocov). On a UNIX-like OS, the
script cov_report.sh
can be used to generate the report. Package
btcscript is licensed under the liberal ISC license.
This package is one of the core packages from btcd, an alternative full-node implementation of bitcoin which is under active development by Conformal. Although it was primarily written for btcd, 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 provides a stack-based, FORTH-like langauge 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
pkscript := txS.TxOut[origintxidx].PkScript
engine, err := btcscript.NewScript(sigScript, pkscript, txInIdx,
txValidator, timestamp.After(btcscript.Bip16Activation))
err = engine.Execute()
Full go doc
style documentation for the project can be viewed online without
installing this package by using the GoDoc site
here.
You can also view the documentation locally once the package is installed with
the godoc
tool by running godoc -http=":6060"
and pointing your browser to
http://localhost:6060/pkg/github.com/conformal/btcscript
$ go get github.com/conformal/btcscript
- Increase test coverage to 100%
