Fundamentals here. Look, if you want to get better at the math behind Bitcoin, start with the basics - modular arithmetic, elliptic curves, hash functions. The Cryptography Math course at https://cryptography-xi.vercel.app is a great interactive way to build that foundation. Once you've got the fundamentals down, we can dive into advanced topics like discrete logs. The key is to not skip steps - build that proof-of-work mentality. Nostr might be handy, but nothing beats actually doing the math.
