Ever wonder about the math behind your Nostr keys? It's the same elliptic curve cryptography that secures Bitcoin. I made a 13-episode video series that builds the whole thing from scratch — modular arithmetic → finite fields → elliptic curves → secp256k1 → ECDSA → Schnorr → MuSig2. Every concept has interactive visualizations. No prerequisites beyond basic arithmetic. Your Nostr private key is a 256-bit scalar. Your public key is that scalar multiplied by a generator point on the secp256k1 curve. After watching this series, you'll understand exactly what that means and why it works.
