Bitcoin development is hard, so learn from those who have already broken ground. Here are projects that are freely available for you to use or build upon to get your own project up and running much faster. Remember Java libraries are compatible with Ruby, Python, Clojure, Scala when running on a JVM.

  • Bitcoin Core - the reference client project on GitHub. Written in C++.
  • Bitcoinj - a Bitcoin library. Written in Java.
  • MultiBit - a Bitcoin wallet. Written in Java based on Bitcoinj.

Bitcoin News and Gossip

Everyone wants to get the low-down on their favourite cryptocurrency, so here are a few news links:

Bitcoin on Reddit

/r/bitcoin (the Bitcoin sub-Reddit) is a very popular outlet for news. Typically there will be 20-30 articles a day relating to the Bitcoin ecosystem and there is no registration required.

This is the home of the ChangeTip Bot which enables Redditors to send each other bitcoins using a simple syntax like:

10 mBTC /u/changetip

The above command will send 10mBTC to whoever you are replying to, even if they don't know about Bitcoin.

There are similar services available for Twitter, Facebook and many other social networking sites.

This illustrates the extraordinary flexibility of Bitcoin and how it dovetails neatly with the rest of the Internet's infrastructure.

Twitter Search

Possibly the fastest way to hear about new developments in the Bitcoin world. Simply run the search and trawl the resulting stream. Use "#bitcoin".

Facebook Page

The Bitcoin Facebook page is another source of information about what is going on in "Bitcoinland". Since no-one owns Bitcoin various users post interesting articles to the page.

BitcoinTalk Forum

This is the original forum dedicated to discussions about Bitcoin. There is a huge turnover of information and many big names in the Bitcoin community make their voices and opinions heard. They have a substantial section to assist beginners and most breaking news about Bitcoin can be found there first.

There is a dedicated MultiBit forum.

Bitcoin on IRC

Internet Relay Chat (IRC) is one of the earliest online chat protocols and it is still going strong with a very large user base.

Bitcoin has several dedicated channels that are very popular and you can join them using the FreeNode website. Just give yourself a user name and you're away. Here are some channels to get your started:

  • #bitcoin (General Bitcoin-related)
