Where can I learn more about blockchain

Hey guys, I'm a recent graduate with an interest in blockchain technology. I have dabbled myself with trading a little bit, but I still consider myself a newbie. My problem is that when I try to follow new blockchain projects or try to learn more about the technology itself, I usually run into keywords that I just don't understand. Stuff like eigenlayer, liquidstaking, ordinal, oracle, layer2, layer3,... I have try to search and educate myself each time I find new keywords, but I find that it's not a good way to learn things systematically. So, does anyone know of a resource where I can learn about blockchain from a to z, like a you tube channel or a block page, or even just a roadmap of what to learn each step to have a full understanding of blockchain macro. Any help would be appreciated.
