Shameless self-promotion but there's also this post I wrote in 2017 if anyone interested in a slightly different take (but a very similar write up to the OP): https://www.samlewis.me/2017/06/a-peek-under-bitcoins-hood/ https://www.samlewis.me/2017/06/a-peek-under-bitcoins-hood/ Cool that this article implements the cryptography primitives, though! e: Funnily, like the article, I also stored some BTC in a wallet and challenged people to (manually) take/steal it. At the time it was worth $10 USD.. now it's worth $123 USD!
