I am teaching myself how to code. My question is if you take an undergraduate computer science degree and you strip away everything that you will either learn on the job or is not relevant for web3. What is left and how can I learn it as quickly as possib

It would be awesome for me to make sort of a checklist of the things I will dig into. I was thinking networking and distributed systems is definitely a topic. But maybe there are things that are either not that crucial to understanding or that I will anyway learn on the go when programming a lot. I already have decent math skills from studying economics, so a lot of math-related things should be fine already. I'm glad over any suggestions.
