This commit contains the entire btcscript repository along with several changes needed to move all of the files into the txscript directory in order to prepare it for merging. This does NOT update btcd or any of the other packages to use the new location as that will be done separately. - All import paths in the old btcscript test files have been changed to the new location - All references to btcscript as the package name have been chagned to txscript This is ongoing work toward #214.

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
|
|
bitcoin transaction scripts.

|
|
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.
