To understand Bitcoin, stablecoins, DeFi: what it's made of, what it's for, and who pays. We always start from the protocol — not the price. If an article doesn't stand up without the word « moonshot », I don't publish it.
80-byte header, nonce and extraNonce, difficulty, from CPU to ASIC, mining economics and pools: we take apart a real block mined on 31 October 2026 to understand what a miner literally does — and who decides what goes into blocks.

UTXOs, binary structure, the Script language, output families, witness and malleability: we take apart a real 222-byte Bitcoin transaction, field by field, until you can read it with the naked eye.
In 2025, Bitcoin Core lifted OP_RETURN's data limit. BIP-110 was the pushback: a temporary soft-fork to re-cap arbitrary data. What it changed, how it was meant to activate — and how, on 8 August 2026, it ended in a chain split, then in a hard fork by the Knots camp.
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.
Platforms, wallets, seed phrase: the practical guide to buying Bitcoin without getting scammed and keeping it safe.
Volatility, energy, crime, regulation: an overview of common objections and real uncertainties around Bitcoin.
I never write about a token while its market cap is under €1B. Not because there's nothing interesting there — quite the opposite — but because the pump & dump risk is too serious for a blog read by beginners. You won't find « x100 » calls here — but you'll find why some happen.
