Hi friend, I also had a hard time understanding the blockchain system, and I did it by sharing information in various forums and Discord groups. But sometimes I was recommended "The Age Of Criptocurrency " written by Paul Vigna and Michael J. Casey. It's a book that explains very well everything related to Bitcoin, blockchain technology and cryptomedas, also does not broaden a little vision on what can become bitcoin one day.
I hope it has been of great help to you,
