On May 22, 2010, Laszlo Hanyecz traded 10,000 BTC for two pizzas. The story, today's value, and the real lesson — which isn't the one you hear everywhere.
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.
SHA-256, secp256k1, ECDSA, Schnorr, address derivation: the cryptographic block that holds Bitcoin together, explained at a useful level without drowning in formulas.
To understand Bitcoin, you first need to understand what we did before it — and why, in 2008, someone decided that wasn't enough anymore.
Blockchain, blocks, mining, proof of work, public and private keys — the essentials, with no jargon.
Programmed scarcity, halving, network effect: why an asset with no industrial use and no state behind it trades at tens of thousands of dollars.
