Explore Bitcoin Core

In the near future I will be demonstrating more concepts using Python code, Jupyter notebook, and Rust. I will be sharing my progress as I learn about Bitcoin, Bitcoin Core and all things related to Bitcoin’s code.

I also recently passed CS120: Bitcoin for Developers with Saylor.org:

Run your own node

All you need is a Raspberry Pi and preferably a 1TB SSD

This is the official guide : https://bitcoin.org/en/full-node#what-is-a-full-node

What other sources of information have I used?

I found Matt Thomas on YouTube to be really good, he is very clear and very thorough. His video on digital signatures was especially helpful.

Digital Signatures – Public/Private Key Encryption

What do you see on a full node?

This is a screenshot of my full node – I leave it on 24/7 and it’s currently using just over half of of the SSD

I can query the Bitcoin blockchain on what is effectively my own personal copy of every transaction every made!

After passing the Saylor.org “Bitcoin for Developers” exam I am now learning more about creating Bitcoin transactions (P2PKH and P2WPKH) and the stack based Bitcoin scripting language.
