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
|
|
|
|
|
|
|
|
|
|
```Go
|
|
|
|
|
pkscript := txS.TxOut[origintxidx].PkScript
|
|
|
|
|
engine, err := btcscript.NewScript(sigScript, pkscript, txInIdx,
|
2013-08-05 22:08:28 +02:00
|
|
|
txValidator, timestamp.After(btcscript.Bip16Activation))
|
2013-06-12 23:35:27 +02:00
|
|
|
err = engine.Execute()
|
|
|
|
|
```
|
|
|
|
|
|
|

|

## 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:
|
|
|
|
|
```bash
|
|
|
|
|
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:
|
|
|
|
|
```bash
|
|
|
|
|
git tag -v TAG_NAME
|
|
|
|
|
```
