btcscript

[] (https://travis-ci.org/conformal/btcscript)

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 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

Sample Use

	pkscript := txS.TxOut[origintxidx].PkScript
	engine, err := btcscript.NewScript(sigScript, pkscript, txInIdx,
		txValidator, timestamp.After(btcscript.Bip16Activation))
	err = engine.Execute()

Documentation

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

Installation

$ go get github.com/conformal/btcscript

TODO

Increase test coverage to 100%

GPG Verification Key

All official release tags are signed by Conformal so users can ensure the code has not been tampered with and is coming from Conformal. To verify the signature perform the following:

Download the public key from the Conformal website at https://opensource.conformal.com/GIT-GPG-KEY-conformal.txt
Import the public key into your GPG keyring:
```
gpg --import GIT-GPG-KEY-conformal.txt
```
Verify the release tag with the following command where TAG_NAME is a placeholder for the specific tag:
```
git tag -v TAG_NAME
```
