Package txscript implements the bitcoin transaction script language. |
|
|
|
A complete description of the script language used by bitcoin can be found at |
|
https://en.bitcoin.it/wiki/Script. The following only serves as a quick |
|
overview to provide information on how to use the package. |
|
|
|
This package provides data structures and functions to parse and execute |

|
Script Overview |
|
|
|
Bitcoin transaction scripts are written in a stack-base, FORTH-like language. |
|
|
|
The bitcoin 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 Bitcoin 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 bitcoins. |
|
|
|
