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
|
||
|
|
|
||
|
|

## 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 the btcsuite developers. 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
|
||
|
|
```
