If you’re technical, read Mastering Bitcoin and Mastering Ethereum, both for free on GitHub https://github.com/bitcoinbook/bitcoinbook, and https://learnmeabitcoin.com/technical/

Reason being is that how most of crypto works is a derivative of bitcoin or ethereum. And, it’s fairly normal in a technical sense, just applied in a unique way that needs to be understood via good ref doc.

Once you wrap your head around those two anchor protocols and get a sense of how it relates to its comp sci primitives (file systems, p2p, cryptographic certs), it can be really demystified - ie “blockchain” is stored as blocks on a file system, in the comp sci sense.
