After Understanding Bitcoin in 5 articles , we step into the machinery. This series is for those who want to really understand how it works: the secp256k1 elliptic curve, the Script language, the 80-byte header miners hash, the Merkle tree, Nakamoto consensus, the BIPs.
10 articles, each readable on its own but designed to be read in order. No programming required — just the desire to look under the hood.
A math side-quest (Math prerequisites ) supports the series for anyone needing a refresher on modular arithmetic, hashing, or the law of large numbers.

The cryptography of Bitcoin
SHA-256, secp256k1, ECDSA, Schnorr, address derivation: the cryptographic block that holds Bitcoin together, explained at a useful level without drowning in formulas.
Math prerequisites for Bitcoin (side-quest)
Modular arithmetic, hash functions, elliptic curves, the law of large numbers — the 4 mathematical building blocks needed to follow the Inside the gears of Bitcoin series, explained as intuition, without heavy formulas.
