dartminer 0.0.1

A Bitcoin miner with Dart language.

Dartminer - An example bitcoin mining package written in Dart.

This is an example application of how to build a Bitcoin mining application using the Dart language. This library is really for reference only and is not intended for live use within a bitcoin mining system. In fact, it doesn't actually publish the solution to the solved blockchain if it finds one, but rather just prints out that it found one. I also recommend only using this application using the TestNet within Bitcoin so that you do not risk of hitting the live network with sample code.

On my machine, I was able to hit hash rate of about 500kH/s, which turns out to be about a 15x speed improvement on a JavaScript implementation... While this is impressive, here's hoping that the Dash VM improves in performance with future releases.

Usage

Below is the steps necessary to get this to work.

• Install the Dart SDK and Editor by going to http://dartlang.org.
• Install the Bitcoin-Qt client by going to https://bitcoin.org/en/download
• Ensure that you run Bitcoin-Qt in testnet mode by following the guide http://suffix.be/blog/getting-started-bitcoin-testnet
• Add this project to your library and then use the following code to mine bitcoins.

import 'package:dartminer/dartminer.dart';

// Our main entry point.
void main() {  
 
 // Create a bitcoin client with the proper configuration.  
 Bitcoin bitcoin = new Bitcoin({
   "scheme": "http",
   "host": "127.0.0.1",
   "port": 18332,
   "user": "bitcoinrpc",
   "pass": "123123123123"
 });
 
 // Get work from the client.
 bitcoin.getwork().then((Map<String, String> work) {
   
   // Create the miner.
   Miner miner = new Miner(work);
   
   // Mine for gold!
   List<int> result = miner.mine();
   
   // Print the result!
   print(result);
 });
}

Enjoy...
