|
Package txscript implements the Decred 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 Decred transaction scripts.
|
|
|
|
## Decred Scripts
|
|
|
|
Decred provides a stack-based, FORTH-like language for the scripts in
|
|
the Decred transactions. This language is not turing complete
|
|
although it is still fairly powerful.
|
|
|
