Package txscript implements the Decred transaction script language.
|
|
|
|
This package provides data structures and functions to parse and execute
|
|
decred transaction scripts.
|
|
|
|
Script Overview
|
|
|
|
Decred transaction scripts are written in a stack-base, FORTH-like language.
|
|
|
|
The Decred script language consists of a number of opcodes which fall into
|
|
several categories such pushing and popping data to and from the stack,
|
|
performing basic and bitwise arithmetic, conditional branching, comparing
|
|
hashes, and checking cryptographic signatures. Scripts are processed from left
|
|
to right and intentionally do not provide loops.
|
|
|
|
The vast majority of Decred scripts at the time of this writing are of several
|
|
standard forms which consist of a spender providing a public key and a signature
|
|
which proves the spender owns the associated private key. This information
|
|
is used to prove the the spender is authorized to perform the transaction.
|
|
|
|
One benefit of using a scripting language is added flexibility in specifying
|
|
what conditions must be met in order to spend decreds.
|
|
|
|
Errors
|
|
|
|
Errors returned by this package are of the form txscript.ErrStackX where X
|
|
indicates the specific error. See Variables in the package documentation for a
|
|
full list.
