Hey! I'm David, cofounder of zkSecurity and the author of the Real-World Cryptography book. I was previously a crypto architect at O(1) Labs (working on the Mina cryptocurrency), before that I was the security lead for Diem (formerly Libra) at Novi (Facebook), and a security consultant for the Cryptography Services of NCC Group. This is my blog about cryptography and security and other related topics that I find interesting.
Ken Shirriff has posted an amazing post on his blog on how he managed to manually make (meaning, he didn't use the official bitcoin application) a transaction in the bitcoin ecosystem.
I'm reading through it as I'm typing this, and it's really well explained, you get to see exactly what he does in Python and there are pictures!
