What sort of research (or where to look) should I be doing to acquaint myself with advances in Blockchain technology?

Hello!

I’m a 21 yr old who is increasingly more interested in the prospects that blockchains and their effects bring to the world of economics. I first showed interest around 12-13 yrs old, as bitcoin was becoming something not many people ever thought it could.

I’d love to dive deeper into advances in blockchain technology that will drive this still-young project to the next level, and what we may expect to see in the future. I’m just unsure how to ACTUALLY find good sources in general knowledge, as many articles nowadays are focused around investment/trading or other reasons I’m not as interested in.

I’m also aware that I do not know much about blockchains besides bitcoin, etherium, and a few other notable names. Even then, I’m not totally knowledgeable about the ones listed previously. Really I’m trying to catch back up to what I’ve missed, as my attention drifted from cryptography to other hobbies (3d printing, baking, foraging, etc.).

I appreciate any and all help and suggestions you all might have, and am excited to be getting back into this incredible frontier. Thank you!!
