SYNOPSIS Build Status

This module provides native bindings to Bitcoin's libbitcoinconsensus functions.
This library is experimental, so use at your own risk.

INSTALL

from npm

npm install libbitcoinconsensus
Note: you will need to have g++/llvm installed first

from git
git clone git@github.com:bitpay/libbitcoinconsensus.js.git
cd libbitcoinconsensus.js
git submodule init
git submodule update
npm install

NOTE: if you get multiple deprecation warnings on Mac OS X, fear not, you are using Apple's built-in libraries, all should work fine ;)

USAGE


'use strict';

var bitcoinconsensus = require('libbitcoinconsensus');

// the transaction spending an output
var txTo = new Buffer('01000000015884e5db9de218238671572340b207ee85b628074e7e467096c267266baf77a4000000006a4730440220340f35055aceb14250e4954b23743332f671eb803263f363d1d7272f1d487209022037a0eaf7cb73897ba9069fc538e7275c5ae188e934ae47ca4a70453b64fc836401210234257444bd3aead2b851bda4288d60abe34095a2a8d49aff1d4d19773d22b32cffffffff01a0860100000000001976a9147821c0a3768aa9d1a37e16cf76002aef5373f1a888ac00000000', 'hex');

// the previous unspent output script
var scriptPubKey = new Buffer('76a9144621d47f08fcb1e6be0b91144202de7a186deade88ac', 'hex');

// the input index that is spending the scriptPubKey
var nIn = 0;

var valid = bitcoinconsensus.verifyScript(scriptPubKey, txTo, nIn);

// valid will equal 0 (false) or 1 (true)
console.log(valid);

// the version of libbitcoinconsensus
var version = bitcoinconsensus.version();
console.log(version);
