Resources Cool stuff.

This isn’t an exhaustive list of Bitcoin resources; it’s more of a list of things I like in case I forget.

I think you may find them useful too.

Bitcoin Implementations

  • Bitcoin Core (C++) - The original and most popular bitcoin implementation.
  • btcd (Go) - Solid implementation with great comments and documentation.


  • bitcoin-ruby (Ruby) - Readable bitcoin code. Excellent for learning how it all works.


  • Electrum (Desktop) - Straightforward and trustworthy wallet.
  • Green (Android/iOS) - Slick, polished, and developed by Blockstream.
  • Mycelium (Android/iOS) - Not as pretty but has stood the test of time.

Blockchain Explorers

  • Learn Me A Bitcoin - I use mine for inspecting raw transaction data.
  • - By far the best overall blockchain explorer. It’s how I’d design my blockchain explorer if I had design skills.
  • Yogh - Sleek blockchain explorer. Beautiful data highlighting.



  • bitcoin-iterate - Handy blockchain parser. Get data out of your blockchain.
  • bitcoin-utxo-dump - Get a human-readable list of UTXOs from your node. Courtesy of yours truly.


  • - The one true wiki for Bitcoin. A definitive resource.
  • Royal Fork - Masterfully written technical articles explaining key parts of Bitcoin.
  • Bitcoin Stack Exchange - Some of the brightest minds and clearest explanations can be found here.


  • RaspiBolt - How to set up a full node on a Raspberry Pi. I think everyone should follow this tutorial at least once.
  • Programming Blockchains (Ruby) - How to write simple blockchain code. Gerald is a good teacher.


  • The Book of Satoshi - A chronological collection of Satoshi’s writing (mailing list and forum posts) in one book. Nicely put together.



  • Bitcoin Only - A clean and well curated list of bitcoin-only resources.
  • - An extensive and well maintained list. A big fan favourite.

How recursive.

Hey there, it's Greg.

I'll let you know about cool website updates, or if something seriously interesting happens in bitcoin.

Don't worry, it doesn't happen very often.
