- Browse through topics at https://ethereum.org/en/developers/docs/
- Explore blocks, transactions and other protocol internals at https://etherscan.io/
- Each YouTube video (Block 1-5) is approx. 1 hour, yikes 😅
- Mastering Ethereum (I hadn't finished the book yet) is a must read, it really explains a lot of complex topics in an understandable manner.
- Ethereum yellow paper is dense, I prefer the Ethereum 'beige paper': https://github.com/chronaeon/beigepaper/blob/master/beigepaper.pdf it is more readable for laymen (such as myself, I have difficulty reading & understanding the mathematical notations from the yellow paper).
- I really liked reading about (albeit it only through a subset of) Ethereum's history: https://vitalik.ca/general/2017/09/14/prehistory.html. Vitalik's older posts are fascinating and you can see how the founders' original ideas evolved over time. There is much more to read and discover, but it's interesting nevertheless.
- EVM illustrated: https://takenobu-hs.github.io/downloads/ethereum_evm_illustrated.pdf is really helpful to visualize a lot of important Ethereum components & concepts.
